Leaky windows can be a serious problem for a homeowner. Even a small crack can lead to significant temperature changes, higher energy bills, and a lack of security.

Repairing a window leak can be a simple DIY job, but it often requires a more skilled professional. Only an expert can identify the root cause of the problem and perform a complete repair.

In this blog, we’ll discuss a few common causes of window leaks, how to identify the problem, how to fix a leaky window, and when to call a pro for the job.

Common Causes of Window Leaks

Many problems can plague your windows over the years, leading to air leaks. It’s important to understand what could cause these issues so you can prevent them in the future. A few common causes of window leaks include:

  • Bad insulation: A poorly leveled window or damaged flashing can result in an air leak.
  • Damaged seals: Broken seals around your windows are a common issue years after installation.
  • Worn-out weatherstripping: Over time, weatherstripping can flatten out and tear, leaving space for air to leak through.
  • Clogged weep holes: Windows with weep holes can drain water away from the window, but they can become clogged and hold water, damaging the window frame.
  • External factors: Heavy rain and strong winds can stress out your windows from the outside.

These problems can happen to even the best windows made of the highest-quality materials. The sooner a problem is found, the sooner a repair can be performed.

 How to Identify if Your Window is Leaking

It can be tough to know for sure if your windows are leaking at all. You may have a problem on your hands if:

  • You notice water damage: There could be a serious leak if you see water stains or wood rot around your windows.
  • You see condensation between window panes: Condensation is a sure sign of a damaged seal between the window panes.
  • Your rooms are cold or drafty: Even a light breeze is confirmation of an air leak.
  • You see mold or mildew development: Mold and mildew can quickly develop when water is present.

If you’re still unsure if you’re experiencing an air leak, try running water over the window to see if it passes through to the outside.

Step-by-Step Instructions on How to Fix a Leaky Window

Repairing a leaky window can be easy with the right tools and knowledge. When you try to fix a leaky window, be sure to:

  • Inspect the frame: Look closely at every part of the window frame for cracks and gaps.
  • Remove old sealant: Clear away old sealants with a utility knife.
  • Clean the surface: Wipe the area with a cloth to prepare for new caulk.
  • Apply new caulk: Add fresh caulk to gaps around the frame.
  • Replace weather stripping: Install fresh stripping if needed.
  • Check weep holes: Clean blockages with a brush or air.
