What Causes Window Leaks?

Windows can start leaking for several reasons, including gaps in the frame or worn-out seals. In some cases, windows may also be improperly installed or be of poor quality due to age. Poorly insulated windows can also cause condensation in colder climates, which can lead to window leakage.

How To Repair Window Leaks

To repair leaking windows, you will need to identify and address the root cause of the problem. Here are some tips for getting started:

  • Check that your windows are properly installed in their frames – Inspect all four sides of each window for gaps where air or water can enter. If they are not level with each other and have gaps around the perimeter, they should be re-installed correctly by a professional contractor.
  •  Check for broken seals – Look closely at any caulking or weatherstripping around your windows. If they appear cracked or worn out, they should be replaced as soon as possible to prevent further leaks from occurring.
  • Clean off dirt and debris – Dirt and debris can build up on window frames over time and create small gaps where air or water can enter through. Make sure that you periodically clean these areas with soap and warm water to make sure that there are no blockages preventing proper sealing around your windows.
  • Install new seals – If necessary, install new caulking or weatherstripping to ensure that there is a good seal between your window frames and walls/windowsill/ceiling (depending on where the leak is coming from). This will help reduce air infiltration as well as prevent water from entering into your home.
  • Add insulation – Adding insulation around your windows will help keep heat in during winter months while keeping cool air out during summer months—this helps reduce energy consumption throughout the year! Additionally, it also helps create an extra barrier against moisture infiltration when combined with quality caulking/weatherstripping materials used in installation/repair processes.


Fixing leaking windows is not always an easy task but it doesn’t have to be overwhelming either—with just a few simple steps such as inspecting frames for gaps, cleaning off debris buildup, replacing old seals, adding insulation, etc., you can easily repair most common window leakage issues without having to call in an expensive professional contractor! With regular maintenance and care taken when installing/repairing windows at home or office buildings alike—leaks will become less likely over time eventually leading to fewer problems down the road! So if you want protect yourself against costly repairs due to leaking windows now is the time take action.
