Some people might be surprised to find that their windows are leaking. Whether you installed them yourself or you had them professionally installed, there are many reasons that windows leak and they all lead back to construction, installation and maintenance of your windows. If you plan on installing your windows yourself, it pays to know all of the errors that can lead to windows leaking to prevent future leaks in your windows.
There are various reasons to ensure that your windows don’t leak. Moisture that leaks in through windows will eventually leak into your walls. When moisture gets inside walls, your home is susceptible to mold, mildew and rot and could turn into a very costly repair. Homeowners can prevent the growth of mold, mildew and rot in their home by purchasing top quality windows, installing them correctly as well as following the manufacturer’s recommendations for maintenance.
Unfortunately there are common mistakes that are made during the installation of windows that causes them to leak:
- Improperly installed or missing flashing – Flashing that is not one continuous piece leaves room for windows to leak. With any break in flashing, there is the potential for water to leak into the siding and eventually into your walls. This is why the flashing is a very important part of installation.
- Lack of overhangs – Overhangs are meant to protect your windows from the elements, especially rain that hits your window quite harshly because of the wind. Depending on the angle of the rain, it could seep into your window, down the siding and into the mounting flange, damaging your walls. A missing overhang or improperly installed overhang leaves your windows susceptible to leaking.
- Lack of caulk – Caulk is the next most important thing from preventing your windows from leaking next to the flashing. Caulk should be used in all areas around the window and especially in nail holes or any other visible holes, to prevent water from leaking into your home.
- Aged glazing putty – Glazing putty doesn’t last forever, it requires periodic maintenance by the homeowner. When glazing putting is left to crack, it allows water to seep into your home.
- Improper materials used – When the installer or yourself uses the incorrect material for flashing, the flashing won’t do what it’s supposed to do and water will leak into your home causing mold and rot.
Whether you plan on installing your windows yourself or hiring a professional installer to install them, it’s imperative that the proper materials are used as well as the proper steps are taken to install your windows to prevent unnecessary leaks and other damage to your home.
