Common Window Water Leakage Issues—and How to Prevent Them Permanently

September 22, 2025

There’s nothing more frustrating for a homeowner than finding water seeping around windows after heavy rainfall. Damp patches, mould growth, peeling paint, and even structural damage are common consequences of poorly sealed or outdated windows. In coastal or high-rainfall areas, these issues become even more severe.

The solution? Investing in a high-quality waterproof window system. Modern aluminium windows and door systems are engineered not only for aesthetics but also for long-term, leak-proof performance.

Common Window Water Leakage Issues

Let’s start by understanding some of the common water leakage issues people face:

1. Poor Sealing Between Frame and Wall

One of the most common causes of water leakage is inadequate sealing between the window frame and the adjacent wall. Small gaps allow rainwater to seep in, causing damage to both interiors and walls.

2. Blocked Drainage Channels

Many traditional windows lack effective drainage systems or their channels become blocked over time. This results in water pooling on the track, which eventually overflows into the home.

3. Worn-out Gaskets

Rubber or inferior-quality gaskets lose their flexibility over time, allowing water to bypass the frame and enter the interiors.

4. Cracked Silicone Sealants

Low-grade silicone sealants used during installation may crack due to exposure to the weather, resulting in leak points that become worse during heavy rainfall.

5. Inappropriate Frame Material

Wooden windows expand in moisture, whereas steel is prone to rust. Both can develop gaps that enable seepage, making them unsuitable for long-term use in coastal or rainy environments.

How to Prevent Window Water Leakage Permanently

Modern waterproof window designs utilise advanced technologies that offer full protection against leaks. Here’s what makes the difference:

1. High-Quality Gaskets

Top manufacturers like Eternia windows and aluminium door and window systems use microwave-cured EPDM gaskets that create a tight seal between frames and sashes. These gaskets:

  • Blocks water, dust, air, and even external noise.
  • Offers superior flexibility and long-lasting durability.
  • Performs effectively even in extreme weather.

2. Advanced Drainage System

An effective drainage system is crucial for waterproofing. Eternia’s aluminium-frame window systems include a one-way drain valve that:

  • Channels water away rapidly.
  • Prevents water build-up within the frame.
  • Eliminates backflow, ensuring smooth operation during heavy rain.

3. Silicone Sealing

To offer extra protection, Eternia windows and aluminium door and window solutions are reinforced with high-grade silicone sealants at all junctions. This guarantees:

  • Zero gaps between profiles and walls.
  • No seepage, even in extreme conditions.
  • A watertight installation that lasts for years.

Together, these technologies make leakage prevention a permanent solution, not just a temporary patch.

Why Aluminium Windows Are the Best Choice

Compared to traditional materials like wooden windows, aluminium windows and door systems are far superior for modern homes:

  • Corrosion-resistant
    Perfect for coastal environments where salty air can lead to rusting.
  • Slim frames with larger glass panels
    Allow maximum natural light while ensuring strong sealing.
  • Durability
    Unlike wood or steel, aluminium does not warp or degrade in high humidity.
  • Modern design
    Complements every home architectural design and adds an elegant and modern look to the space.

When paired with waterproofing technology, aluminium frames offer the most reliable solution for long-term protection and comfort.
