Have you ever taken a closer look at the grout in your shower and wondered if those dark stains or cracks are harmless—or hiding something more serious?
While grout might seem like a minor detail in your bathroom, neglecting it can quietly cause significant problems. In many Perth homes, ageing grout is a common but often overlooked issue, especially given the city’s humid climate and the constant moisture in wet areas. When grout starts to deteriorate, it doesn’t just affect the look of your shower—it opens the door to mould growth, water leaks, and even structural damage behind the tiles.
This blog will uncover the hidden dangers of neglected grout and why addressing it early is crucial for your health, home, and hip pocket. If you’ve been putting off maintenance or haven’t considered a shower regrouting service in Perth, now is the time to learn why it could save you thousands—and keep your bathroom clean, safe, and watertight.

What Is Shower Grout and Why Does It Matter?
Shower grout might seem like a background element in your bathroom, but it plays a critical role in the overall structure, hygiene, and longevity of your wet areas. Understanding what grout does—and why it deteriorates—is essential to recognising when it’s time for action.
The Role of Grout in a Shower
Grout is a product made from a mixture of cement, sand, and water. Once applied and hardened, it acts as the filler between tiles. While often seen as a purely cosmetic material, its role in a bathroom—especially the shower—is far more significant.
Waterproofing Function
Grout’s primary job is to seal the gaps between tiles and prevent water from seeping into the surfaces underneath. While grout itself is not fully waterproof, it contributes to the water resistance of the tiled area, especially when paired with proper sealing. Without intact grout, water can easily penetrate behind the tiles, leading to moisture buildup, mould growth, and eventual damage to the surrounding walls and floors.
Structural Integrity and Hygiene
Grout also keeps tiles in place and supports the structural integrity of the tiled surface. Cracked or missing grout allows tiles to shift, which can weaken the wall or floor over time. On top of that, compromised grout lines create crevices where bacteria and mould can thrive, leading to hygiene issues that are tough to resolve with cleaning alone.
Aesthetic Contribution
From a visual standpoint, neat grout lines enhance the overall appearance of your bathroom. Clean, uniform grout frames your tiles and gives the space a polished, well-maintained look. Discoloured or crumbling grout, on the other hand, can make an otherwise updated bathroom look tired and neglected.
Why Grout Is Vulnerable Over Time
Despite its crucial function, grout is far from invincible. Over time, it naturally deteriorates—and in a high-use, high-moisture environment like a shower, this process is often accelerated.
Constant Exposure to Moisture and Cleaning Agents
In a shower, grout is subjected to water exposure daily. This repeated saturation weakens the material, especially if the grout was not properly sealed or has aged past its effectiveness. In addition, harsh cleaning products and scrubbing can erode the surface of the grout, wearing it down and reducing its ability to protect the tiled surface beneath.
Effects of Perth’s Climate: Humidity, Temperature Fluctuations, Hard Water
Homes in Perth face unique environmental challenges. High humidity levels, especially in winter, create the perfect conditions for mould and mildew growth in deteriorating grout lines. Sudden temperature shifts—common when hot showers meet cold tile surfaces—can cause grout to expand and contract, leading to cracking over time. Hard water, prevalent in many areas of Perth, also leaves mineral deposits that degrade grout and make it more porous.
Recognising the importance of grout and the reasons for its decline is the first step in protecting your bathroom. The next step is learning how to spot the warning signs—which we’ll cover in the next section.
Common Signs Your Shower Grout Needs Attention
Many homeowners don’t realise there’s a problem with their grout until it’s too late. The early signs of grout damage can be subtle, but recognising them in time can save you from more extensive repairs, water damage, and health risks. Below are the most common visual and functional indicators that your shower grout may be compromised.

Visual Indicators
A quick visual inspection of your shower can reveal a lot about the health of your grout. Keep an eye out for the following red flags:
Cracks, Gaps, or Crumbling Grout
One of the most obvious signs that grout is failing is the presence of visible cracks or missing sections between tiles. Grout should appear solid and intact. If it looks chipped, powdery, or is crumbling away, water is likely penetrating these weak spots and reaching the underlying surfaces.
Discolouration or Staining
Grout that has turned dark, patchy, or uneven in colour may be absorbing moisture or hosting mould. While light staining can sometimes be cleaned, persistent dark or black stains—especially along grout lines—often indicate deeper issues like mould spores or embedded dirt that regular scrubbing won’t fix.
Mildew or Soap Scum Buildup Despite Cleaning
If your shower always seems to look dirty even after thorough cleaning, damaged grout might be the culprit. Mould and mildew thrive in damp, porous grout, especially when it’s lost its protective seal. Soap scum can also build up more quickly on degraded surfaces, making the area look grimy even after fresh scrubbing.
Functional Issues
Even if your grout appears somewhat intact, your shower may still be showing signs of failure beneath the surface. Here’s what to watch for:
Persistent Damp or Musty Odours
A lingering musty smell in your bathroom—especially after the shower has dried—can signal hidden moisture trapped behind tiles or within wall cavities. This often occurs when grout is compromised and water begins to seep into places it shouldn’t.
Water Pooling or Leakage
Are you noticing water collecting outside your shower or near the base of the wall? This can be a clear indication that water is bypassing your grout lines and leaking into adjacent areas. Over time, these leaks can cause costly damage to flooring, cabinetry, and even substructures. In such cases, professional service for leaking shower repairs may be needed to address the root cause.
Increased Humidity in Nearby Rooms
When water escapes from your shower enclosure through damaged grout, it can increase the overall moisture levels in surrounding areas. This might manifest as fogged-up mirrors, damp patches on walls, or even peeling paint in adjacent rooms. These subtle signs often go unnoticed until more serious water damage becomes visible.
Staying vigilant and knowing what to look for can prevent minor grout issues from becoming major home repairs. In the next section, we’ll explore how neglected grout can pose serious health risks if left unaddressed.
Health Risks of Neglected Shower Grout
It’s easy to think of grout as just a cosmetic feature in your bathroom, but when it’s neglected, it can become a serious health hazard. Damaged or deteriorating grout creates the perfect environment for mould, mildew, and bacteria to thrive—often out of sight. These biological threats don’t just affect your bathroom; they can impact the air quality throughout your home and negatively affect your health, especially if you have children, elderly family members, or anyone with allergies or respiratory issues.
Mould and Mildew Growth
One of the most common—and dangerous—consequences of neglected shower grout is mould. In the moist, humid environment of a bathroom, even small cracks or porous grout lines can allow water to seep in and linger, creating the perfect conditions for fungal growth.
Respiratory Health Impacts
Mould releases tiny spores into the air, which are easily inhaled. For some, this might cause mild irritation like sneezing or coughing. But for others—especially those with asthma, bronchitis, or other respiratory conditions—these spores can trigger severe allergic reactions, wheezing, and difficulty breathing. Children and older adults are particularly vulnerable to the effects of mould exposure.
Long-Term Exposure Risks
Chronic exposure to mould has been linked to more serious health concerns such as persistent sinus infections, fatigue, skin irritation, and even cognitive issues in extreme cases. Because bathrooms are often enclosed spaces, the concentration of airborne spores can be high, leading to constant low-level exposure over time.
How Mould Takes Hold in Grout
Grout is naturally porous, and when it begins to crack or deteriorate, it traps moisture deep within its surface. Add in soap residue, shampoo build-up, and warm air, and you have a recipe for rapid mould growth. Without sealing and proper maintenance, even small patches can spread quickly behind tiles and into hidden wall cavities.
Bacterial Buildup
Mould isn’t the only microorganism you need to worry about. Damaged grout also harbours bacteria, which can multiply rapidly in the damp, warm conditions of your shower area.
Hygiene Concerns
Bathrooms are high-traffic, high-contact areas, and when grout becomes compromised, it can trap not just water but skin cells, body oils, and organic material that bacteria feed on. This leads to hidden biofilms forming inside grout lines, making the surface much harder to clean effectively with household products.
Skin Infections and Irritation
Standing barefoot in a contaminated shower or touching infected surfaces can expose you to bacteria that may cause skin irritation, fungal infections, or rashes—particularly for those with sensitive skin or weakened immune systems. Small cuts or abrasions on the skin are especially vulnerable to infection in this environment.
Increased Risk in Shared Bathrooms
In homes where multiple people share the same bathroom, the risk is even greater. Shared showers mean more moisture, more exposure, and higher chances of cross-contamination if bacteria are allowed to flourish in neglected grout.
Ignoring the health implications of failing grout can put your household at risk in ways many homeowners never realise until it’s too late. The next section explores how this hidden problem can also lead to serious structural damage in your home.
Structural Damage to Your Home
While the health risks of neglected shower grout are reason enough for concern, the potential for structural damage to your home is even more alarming. Water that bypasses broken or deteriorated grout doesn’t just stay confined to the shower area—it seeps into walls, floors, and even the substructure of your bathroom. Over time, this silent damage can result in significant repair costs and compromise the integrity of your property.
Water Ingress Behind Tiles
The most immediate and common consequence of failed grout is water ingress—where moisture penetrates behind the tiles and reaches the substrate beneath.
Wall and Floor Damage
Once water reaches behind the tiled surface, it can cause swelling and degradation of the materials behind it, such as plasterboard, timber studs, or cement sheeting. These materials are not designed to be constantly wet and will deteriorate rapidly, leading to soft walls, sagging surfaces, and tile displacement.
Warping, Swelling, and Rot
In timber-framed bathrooms, water that seeps through damaged grout can lead to wood swelling, warping, and eventually rotting. This is particularly problematic around shower bases and behind wall cavities, where the moisture remains undetected for extended periods.
Spread to Adjacent Rooms
Water doesn’t stay put. If left unchecked, leaks from the shower can affect adjoining rooms, such as wardrobes, bedrooms, or hallways. You might start to notice peeling paint, warped skirting boards, or unexplained damp patches—often long after the grout damage has occurred.
Escalating Repair Costs
One of the most frustrating aspects of grout failure is how quickly a relatively inexpensive issue can spiral into a costly renovation.
From Minor Leak to Major Renovation
What starts as a few missing patches of grout can soon escalate into a full tile replacement or bathroom remodel. Once water has infiltrated behind your tiles, simply re-grouting may not be enough—damaged substrates, wet insulation, and mouldy wall cavities will need to be replaced entirely.
Hidden Damage Is Expensive to Fix
Because much of the structural damage caused by grout failure happens behind the scenes, it often goes unnoticed until the situation becomes severe. This results in more invasive repairs, including ripping out tiles, removing wall panels, and replacing structural timber or waterproofing membranes.
Prevention Is Far More Affordable
A professional grout repair service in Perth can identify and resolve these issues early—often without the need for major renovations. Regrouting and resealing at the first sign of wear is not only more affordable but also far less disruptive than dealing with large-scale water damage and rebuilds.
Structural issues caused by neglected grout often develop quietly, but their impact is long-lasting and expensive. Addressing these problems early is key to protecting your investment and maintaining the safety of your home. In the next section, we’ll look at the financial implications of delaying grout maintenance.
The Financial Consequences of Ignoring Grout Issues
Neglecting shower grout isn’t just a risk to your health and home—it can also hit you hard financially. Many homeowners postpone maintenance, thinking it’s a cosmetic issue or a low priority, only to be faced with hefty repair bills, decreased property value, and complications with insurance claims. Understanding the broader financial impact of grout damage can help you make a more informed—and cost-effective—decision.
Lower Property Value
A bathroom in poor condition is one of the fastest ways to devalue your home. Even if the rest of your property is in excellent shape, visible grout damage or signs of moisture can turn off potential buyers and devalue your listing.
Bathroom Condition Affects Buyer Confidence
Real estate agents often stress the importance of well-maintained wet areas. When buyers inspect a home, bathrooms are high on the checklist—and signs of water damage, mould, or crumbling grout immediately raise red flags. They might assume there are hidden structural issues or that a costly renovation is required.
Grout Issues Are a Telltale Sign of Neglect
Even something as seemingly minor as stained or missing grout can signal to buyers that other areas of the home may have been overlooked. This perception can lead to lower offers or the need for seller concessions to cover potential repairs.Higher Utility and Repair Bills
Letting grout damage persist doesn’t just compromise your home’s condition—it also results in recurring expenses that can add up quickly.
Increased Water Usage from Hidden Leaks
Cracks in grout lines can allow water to escape during every shower, which adds up over time. Even a slow leak can waste hundreds of litres of water each month, contributing to unnecessarily high utility bills.
Ongoing Costs for Cleaning and Maintenance
Neglected grout often leads to mould and mildew buildup, which means more frequent and aggressive cleaning. You may find yourself constantly buying mould removal products, scrubbing grout with harsh chemicals, or even hiring professional cleaners—costs that could have been avoided with proper maintenance.
Small Repairs Become Major Expenses
What could have been resolved with a simple regrouting service can snowball into thousands of dollars in repairs if left unattended. Damaged tiles, rotting walls, and failed waterproofing all require significant investment to fix, especially if water has migrated to other areas of the home.
Insurance Claim Complications
Many homeowners assume that if water damage occurs, their insurance will cover the repairs. However, that’s not always the case when it comes to preventable issues like neglected grout.
Insurance May Deny Preventable Damage
Most home insurance policies do not cover damage caused by maintenance neglect. If an assessor determines that water damage resulted from cracked or unsealed grout that was left unrepaired, your claim may be denied—leaving you to foot the bill.
Delayed Reporting Weakens Claims
Even if your policy includes water damage coverage, insurers often require timely reporting. The longer you delay addressing grout issues, the harder it becomes to prove the damage was sudden or unavoidable, further reducing the likelihood of a successful claim.
Taking a proactive approach to grout maintenance doesn’t just protect your bathroom—it protects your wallet. In the next section, we’ll look specifically at why homes in Perth are especially vulnerable to grout issues and water damage.
The Financial Consequences of Ignoring Grout Issues
Ignoring deteriorating shower grout doesn’t just pose health and structural risks—it can significantly affect your finances. Many homeowners delay addressing grout problems, believing they’re purely cosmetic. But when left untreated, these small issues often lead to substantial expenses, reduce property value, and complicate future maintenance and insurance claims. Below, we explore how overlooking grout can cost you more than you might expect.
Lower Property Value
Bathrooms are among the most scrutinised spaces during property inspections and valuations. The condition of your grout plays a bigger role in buyer perception than most realise.
First Impressions Matter
When potential buyers tour a home, a fresh and clean bathroom creates an impression of care and quality. On the other hand, cracked, mouldy, or missing grout can make the entire bathroom feel neglected. This can reduce the buyer’s perceived value of the home, even if the rest of the property is in excellent condition.
Hidden Costs Scare Off Buyers
Visible grout damage may lead buyers to assume there are deeper, unseen issues—such as water damage or poor waterproofing. Many prospective homeowners may factor in the cost of tile repairs or full renovations, resulting in lower offers or difficulty selling the home altogether.
Higher Utility and Maintenance Costs
Minor grout issues often spiral into more expensive problems when left untreated.
Water Waste and Hidden Leaks
Compromised grout allows water to seep through to the areas behind your tiles. Even small leaks can waste a surprising amount of water over time, increasing your utility bills. Since these leaks usually go undetected until more serious damage appears, the costs can accumulate before you even realise there’s a problem.
Ongoing Cleaning Costs
Neglected grout is prone to mould, mildew, and soap scum build-up, which requires constant scrubbing and specialised cleaning products. Over time, these recurring expenses add up. Even professional cleaners may struggle to restore heavily damaged grout, leaving you with no choice but to seek bathroom repairs.
Major Repair and Renovation Expenses
Failing to maintain grout doesn’t just lead to cosmetic damage—it often results in the need for larger, more invasive repairs.
From Surface Damage to Structural Repairs
Once water penetrates beneath the tiles, it can affect the waterproofing membrane, damage wall studs, and compromise flooring. At this stage, simple patch-ups are no longer an option. Homeowners may face the cost of removing tiles, replacing damaged substrates, and restoring the waterproof barrier—all of which are far more expensive than routine maintenance.
The Value of Early Intervention
By addressing grout deterioration early through a trusted regrouting company, you can prevent small issues from becoming major, costly renovations. A professional team can assess the extent of the problem, replace compromised grout, and reseal surfaces properly—saving you thousands in long-term repair costs.
Insurance Limitations and Exclusions
Many homeowners assume insurance will cover any water damage in the bathroom. Unfortunately, this isn’t always the case—especially when the cause is linked to poor maintenance.
Wear and Tear Isn’t Covered
Most insurers won’t cover damage resulting from gradual deterioration or neglect. If cracked grout or a failed waterproofing system is identified as the source, your claim may be denied. The cost of repairs will then fall entirely on you.
Delayed Action Reduces Coverage
Even if your policy includes water damage protection, delayed maintenance can reduce your payout or void the claim altogether. Regular upkeep and early repair by professionals are key to maintaining coverage and avoiding financial setbacks.
When it comes to shower grout, a “wait and see” approach often leads to higher costs and more inconvenience. Acting early with the help of experienced professionals protects your property, your health, and your budget. In the next section, we’ll examine why homes in Perth face a unique set of challenges when it comes to grout damage and moisture issues.
Why Perth Homes Are Especially at Risk
While shower grout issues can affect any home, Perth properties are particularly susceptible due to a unique combination of environmental, architectural, and maintenance-related factors. Understanding these localised risks can help homeowners take a more proactive approach to protecting their bathrooms from water damage and costly repairs.
The Impact of Local Climate Conditions
Perth’s climate plays a significant role in how quickly grout deteriorates. The combination of warm temperatures, fluctuating humidity levels, and hard water can accelerate grout failure if not addressed with the right materials and maintenance techniques.
High Humidity Levels
Although Perth has a Mediterranean climate, indoor spaces like bathrooms tend to trap humidity—especially in older homes with poor ventilation. Showers generate steam that lingers on walls and tiles, creating a moist environment where grout stays damp for extended periods. Prolonged moisture exposure weakens grout, encourages mould growth, and allows water to seep behind tiles.
Temperature Fluctuations
Daily and seasonal temperature changes cause grout and tiles to expand and contract. These micro-movements, though often imperceptible, can lead to cracks over time—particularly if the grout mix was not formulated to withstand such shifts. Cracked grout invites moisture, compounding the risk of leaks and internal water damage.
Hard Water Deposits
Many Perth suburbs have hard water, which contains high levels of calcium and magnesium. Over time, these minerals build up on tile surfaces and within grout lines, making them more brittle and prone to cracking. Hard water also encourages soap scum and mineral staining, which can mask early signs of grout damage.
Aging Housing Stock and Common Renovation Pitfalls
Beyond climate, the condition and age of many Perth homes also contribute to widespread grout issues. Bathrooms built decades ago or renovated without proper waterproofing standards are particularly vulnerable.
Older Homes with Outdated Materials
Many older Perth homes were constructed with grout and sealants that do not meet today’s performance standards. In some cases, original grout wasn’t waterproof or flexible, making it highly susceptible to cracking and erosion over time. Without regrouting or resealing, these materials are likely to fail under modern usage patterns.
DIY Fixes That Mask Deeper Issues
Homeowners often attempt quick fixes for damaged grout, such as applying silicone over gaps or using off-the-shelf patch products. While these solutions may offer a temporary improvement in appearance, they rarely address the underlying problem. In fact, they can trap moisture underneath and delay proper intervention—ultimately increasing the scope and cost of repairs.
Inadequate Waterproofing During Renovations
Some budget bathroom renovations in Perth have skipped essential waterproofing steps or used subpar materials. This leaves grout and tiling systems vulnerable from day one. When grout begins to deteriorate, the absence of a robust waterproofing membrane behind it means moisture has a direct path into walls and floors, escalating the risk of mould and structural damage.
Perth homeowners need to be especially vigilant about grout maintenance due to these combined environmental and construction-related factors. In the next section, we’ll explain how professional shower regrouting addresses these challenges and protects your bathroom for the long term.
How Professional Shower Regrouting Solves the Problem
When grout begins to fail, many homeowners assume that constant cleaning or DIY sealants will do the trick. Unfortunately, these short-term fixes rarely address the root cause. Professional shower regrouting, on the other hand, offers a lasting solution that restores both the function and appearance of your bathroom. This section explains how expert regrouting services work and the long-term benefits they provide.
AllSealed WA’s Approach to Shower Regrouting
At AllSealed WA, shower regrouting isn’t just a surface-level patch-up—it’s a comprehensive process that targets water ingress, mould prevention, and long-term durability. Their specialised methods are designed to suit Perth’s unique climate conditions and common home construction styles.
Removal of Damaged Grout
The first step involves carefully removing all the deteriorated or compromised grout between your shower tiles. Unlike superficial touch-ups, professional regrouting involves full-depth removal to expose clean, dry surfaces beneath. This ensures the new grout can bond securely and provide a watertight seal.
Application of Anti-Mould, Waterproof Grout
Once the old grout is removed, AllSealed WA applies high-quality, mould-resistant grout that’s specifically formulated for wet areas. This new grout is not only more durable but also contains anti-fungal agents to inhibit mould and mildew growth, providing better protection for your home and your health.
Precision Sealing and Finishing
After regrouting, the area is sealed with premium-grade products that further enhance water resistance. This step is essential for preventing future water penetration and ensuring the longevity of the newly applied grout. The result is a clean, smooth, and fully sealed shower area that looks and performs like new.
Benefits of Timely Regrouting
Professional regrouting does more than solve an immediate problem—it delivers long-lasting results that protect your bathroom and home from further deterioration. Here are the key benefits:
Restored Waterproofing
By replacing degraded grout with modern, water-resistant materials, regrouting restores your shower’s primary barrier against leaks. This helps prevent water from seeping into walls and floors, preserving the integrity of your bathroom’s structure.
Improved Hygiene and Air Quality
Old, mouldy grout is a magnet for bacteria and fungal spores. Regrouting eliminates these issues at the source, improving the cleanliness of your shower and contributing to better indoor air quality—especially important for those with allergies or respiratory concerns.
Enhanced Aesthetic Appeal
New grout can dramatically transform the look of your shower, making tiles appear fresher and more vibrant. It’s a cost-effective way to rejuvenate your bathroom without the need for a full renovation.
Cost Savings Over Time
Addressing grout problems early prevents small issues from becoming major expenses. Professional regrouting is significantly more affordable than full bathroom repairs, waterproofing redos, or structural restorations caused by water damage.
Increased Property Value and Buyer Appeal
If you’re planning to sell your home, a regrouted shower shows prospective buyers that the bathroom is well-maintained. It signals quality and care, boosting both property value and marketability.
When performed by experienced professionals like AllSealed WA, shower regrouting delivers long-term peace of mind. It safeguards your home, enhances its appearance, and protects your health—all with minimal disruption. In the next section, we’ll explore the key warning signs that it’s time to call in the experts.
When to Call a Professional: Key Warning Signs
Many homeowners wait too long before seeking help with their shower grout, only acting once damage becomes obvious or unmanageable. However, recognising early warning signs can save you from costly repairs and protect your home’s long-term health. If you notice any of the following issues in your bathroom, it’s time to call in a professional regrouting specialist.
Grout That Looks Patchy, Cracked, or Discoloured
Your shower walls and floor should have consistent, intact grout lines. If you see areas where the grout is cracked, crumbling, or falling out entirely, this is a clear sign the material has failed. Similarly, widespread discolouration—particularly if it’s dark or spotty—may indicate mould or water absorption beneath the surface.
Surface Disrepair Is Just the Start
What you see on the surface often reflects deeper damage. Missing or damaged grout allows water to seep behind tiles, which can lead to compromised waterproofing and structural deterioration over time. If grout damage is visible, the problem has likely already begun to spread beneath the surface.
Persistent Mould That Won’t Go Away
Cleaning your shower regularly but still dealing with stubborn mould in the grout lines? This is a red flag. Mould thrives in damp, porous environments—and once grout loses its seal or integrity, it becomes nearly impossible to keep dry.
Why Cleaning Alone Isn’t Enough
Bleach and mould-removal sprays may clear surface stains temporarily, but they don’t eliminate mould embedded deep within failing grout. Continued growth indicates that moisture is penetrating where it shouldn’t, and only full removal and replacement will fix the issue properly.
Water Leakage Outside the Shower Recess
One of the most serious signs that grout failure has gone too far is when water begins to appear outside the shower enclosure. You might notice damp patches on adjacent walls, wet flooring near the base of the shower, or discolouration on ceilings below second-storey bathrooms.
Leaking Showers Can Lead to Widespread Damage
If left unchecked, water from the shower can spread to adjoining rooms or levels, leading to warped skirting boards, peeling paint, or damage to flooring. In severe cases, it can even affect outdoor areas—similar to how a leaking balcony repair may be required when water seeps into external structures. Both scenarios stem from poor waterproofing and deteriorated sealing materials like grout and silicone.
Tiles That Feel Loose or Sound Hollow
If your shower tiles no longer feel firmly set, or if they make a hollow sound when tapped, this could mean that water has infiltrated behind them. Loose tiles are often the result of adhesive breakdown caused by moisture, and they pose a risk of cracking or falling off entirely.
Underlying Moisture Is Usually the Culprit
This is not just an aesthetic concern—it indicates that the bond between the tile and substrate has been compromised, typically due to long-term water exposure. Professional assessment is needed to determine whether regrouting alone is sufficient or if further repairs are required.
Recognising these early signs and acting quickly can prevent further deterioration and avoid more costly interventions down the line. In the next section, we’ll explore why AllSealed WA is the trusted choice for regrouting and leak repairs in Perth.
