Common Causes of Window Leaks During Rain

There are several reasons why your windows may be leaking during heavy rainfall. Understanding the underlying cause will help you decide on the right course of action for repair or replacement.

1. Worn-Out Window Seals

Over time, the rubber seals around windows can deteriorate due to constant exposure to the elements. When these seals crack or wear out, rainwater can seep through, especially during heavy downpours. Aged or damaged seals are one of the most common causes of window leaks.

2. Faulty Installation

If your windows weren’t installed correctly from the start, leaks may occur. Poorly sealed edges, gaps between the frame and the wall, or unlevel installation can allow water to penetrate the structure when it rains.

3. Clogged or Damaged Weep Holes

Weep holes are tiny drainage openings found in many windows that help water drain out. If these holes become blocked with dirt or debris, water can collect inside the window frame and eventually leak into your home.

4. Structural Shifts

Over time, your home may settle or shift slightly due to weather conditions, temperature changes, or aging. This can create gaps between the window frame and the surrounding wall, allowing rainwater to enter.

5. Poorly Fitted Window Frames

Windows that no longer fit snugly in their frames due to wear and tear or structural changes in the home can cause leaks. Even slight gaps can let in moisture during a rainstorm, which then trickles into the home. A new replacement of window also need a special care and ensure the gaps are properly waterproof and sealed. Select a correct window frame section is essential.

Replacing old, cracked, or damaged weatherstripping is an inexpensive fix that can make a big difference in keeping rainwater out. If the water is dripping of the frame, installation of weather plate on the frame is important if the gaps of the frame is big.

3. Clean or Unclog Weep Holes

Blocked weep holes are a common cause of leaks. Simply clean out the dirt or debris with a small brush or toothpick to restore proper drainage and prevent water from accumulating in the window frame. Remove the clog and do not seal it off if it did by previous contractor.

4. Install Flashing Tape

Flashing tape is a waterproof adhesive tape used to seal gaps around windows and doors. Applying flashing tape around the exterior of your windows can reinforce weak spots where water might enter.

When Is It Time to Replace Your Window?

While repairs can often fix minor leaks, there comes a point when it’s more cost-effective to replace your windows. Here are some signs that it’s time for a window upgrade:

2. Visible Damage

Cracked window panes, warped frames, or peeling paint are all indicators that your windows have seen better days. These issues can compromise the structural integrity of your windows and increase the likelihood of leaks.

3. Poor Energy Efficiency

Older windows are often less energy-efficient, allowing heat to escape during cooler months and letting in too much sunlight during hot periods. If you notice higher utility bills or temperature fluctuations, replacing your windows can improve energy efficiency and prevent future leaks.

4. Difficulty in Opening or Closing

Windows that are hard to open or close properly are often a sign of wear and tear. Malfunctioning windows may not seal tightly, which can lead to water intrusion during rain.

If you notice condensation forming between double-pane windows, it’s a sign that the seal between the panes has failed. This can not only lead to leaks but also reduce the insulation and efficiency of the window.
