Weathering the Storm: How Weather Conditions Impact Balcony Leaks

Balcony leaks are a common problem in many homes, especially in areas with high rainfall or extreme weather conditions. Not only can these leaks cause significant damage to the structure of a home, but they can also become a serious health hazard if not addressed promptly. In this article, we will explore the relationship between weather conditions and balcony leaks and offer practical advice on protecting properties.

The Relationship Between Weather and Balcony Leaks

The Role of Rain

The most direct and obvious connection between weather and balcony leaks is rainfall. When it rains, water can seep into any cracks or gaps in the balcony’s surface, leading to leaks. The situation worsens when rainwater cannot drain properly due to clogged or poorly constructed drainage systems. Consequently, standing water can exacerbate the damage, leading to more severe leaks.

Temperature Fluctuations

Extreme temperature changes, especially in regions that experience scorching summers and freezing winters, can significantly affect the integrity of a balcony’s structure. When the temperature fluctuates, different types of building materials expand and contract at different rates, therefore, leading to cracks and gaps where water can infiltrate, resulting in leaks.

Wind and Storms

High winds and storms can accelerate the damage caused by rain and temperature changes. They can drive rainwater into places it would not normally reach, including under doors, through window frames, and into cracks and crevices in the balcony’s surface. Severe storms can also damage the exterior sealant, rendering it ineffective against leaks.

How to Protect A Balcony from Leaks

Regular Inspection and Maintenance

Prevention is always better than a cure. Regular inspection of the balcony must occur for any signs of damage, including small cracks, separation to perimeter joints, bubbling/flaking paint, physical water or signs of mould. These issues must be addressed immediately to prevent further deterioration.


Waterproofing a balcony is one of the best ways to protect it from leaks. This involves applying a waterproof membrane or coating to the balcony’s surface prior to tiling, which can help prevent water from penetrating the surface. Additionally, the use of an epoxy grout product in the grout joints and perimeters will stop any leak to the substrate and keep water out.

Proper Drainage

Ensuring the balcony has a proper drainage system is essential to preventing leaks. This means that any rainwater that lands on the balcony should be directed away from the building, preventing it from pooling and causing damage.

Hire Professionals

If you’re unsure how to protect a balcony from leaks, consider hiring a professional. They can assess its condition and recommend the appropriate solutions, carrying out the necessary repairs or preventative measures.

Final Thoughts

Weather conditions can have a profound impact on the integrity of a balcony, leading to leaks that can cause extensive property damage. It’s crucial to understand the impact of weather and take the necessary steps to reduce the likelihood of property damage.
