Five Causes of Leaky Windows
If summer storms have left you with a wet mess around your windows, it's time to take a close look at what might be happening to them. Improper installation, age and lack of maintenance can all take their toll on your hardworking windows.
Learn what might be causing your window leaks. If it's time to replace one or two windows, call an experienced contractor who can install new, energy-efficient windows for you before the winter storms hit.
1. Faulty Flashing
Flashing that was not installed properly is almost as bad as having no flashing at all. Always remember that flashing tape needs to be put in as a continuous piece, not in patches.
Most modern, energy-efficient windows are equipped with protective features that make your flashing cling better, preventing gaps and water leaks.
If faulty flashing is your problem, you can try a temporary repair involving new flashing tape and caulk. This might be enough to keep leaks at bay, but eventually, you will probably have to replace that window.
2. Sloppy Sealing
Are you seeing water on your window pane? If the water is on the interior pane that's inside your house, it's probably just condensation. Condensation doesn't mean the window is leaking, but it could be a sign that humidity levels in your house might be too high.
But if you're seeing droplets on the interior glass, between the panes of a double-paned window, that's a signal that the argon glass used to insulate the windows has sprung a leak.
Lost argon means you've lost the window's insulating properties and the only way to fix this problem is to replace the window.
Sealant breaks can happen during manufacturing, so check the manufacturer's warranty for your window. If it is out of warranty, you'll need to replace it.
3. A Bad Fit
Windows that don't shut properly won't do anything to keep wind, rain, cold or heat out of your house. Gaps in your window seal are especially inviting to rainwater, which will enter your home at will through a window leak.
Before you decide that the window is faulty, try this simple step. Close the window and lock it. Many of us don't lock our windows when we close them, because it's a pain to keep doing it when we frequently open and close them. Locking helps hold the window tight against the wall. If you lock it and the window still lets air or water in, it's time to replace the caulking and perhaps the window itself.
4. Perfect Painting
This one might be a surprise to some people. If you recently repainted the room that the window is in, did you carefully remove every trace of paint from the window panes?
If so, you might like the neat look, but you didn't do your window any favors. In order to maintain a tight, insulating seal on your windows, you should always allow a slight overlap of paint onto the glass.
Paint helps act as a sealant, locking out air and moisture. It's possible to leave that tiny overlap and still have a paint job that looks neat and professional, but you may have to hire a professional to do it.
5. It's Not the Window
It's possible that your window isn't to blame at all. The leak might be coming from inside your house. If you're seeing water form at the top of the window frame, chances are you have a leak from your walls. Water might be entering from your roof or your siding and showing up on top of your window. In that case, it's important that you find the source of the leak and repair it.
