When’s the best time to spot a leaking window? In the middle of a rainstorm, of course. When’s the worst time to fix a leaking window? Ditto. Don’t panic, though. Get out your phone and take a picture of the mess instead. That way, if you need to call a pro to take of your problem, you’ll have clear evidence as to the location and severity of the leak. And, as an informed consumer, do your homework by checking out these leaking window causes and cures.

2. Look at your window seal. The glass of your window should be solidly sealed to a rubber or vinyl gasket within the frame. If the pane has loosened over the years, renew the seal, using transparent silicone caulk.

3. Check your window frame. If the frame is the cause of your leaking window, there are several possible repair scenarios, as follows:

4. Consider other possible sources of leakage. Sometimes, water that appears to be the result of a leaking window is really coming from another source altogether. Make sure that the source of the leak is not actually your home’s roof, exterior walls, or upstairs bathroom.

5. Minimize water damage. If heavy rain makes window repair impossible for the time being (or if you’re waiting for a pro to arrive and fix the problem), meanwhile you can at least minimize water damage, which, unchecked, may lead to mold and rot. Place a rolled up towel or large rag in the area of the leak — to absorb that darn water — and change it regularly for a dry one. If at all possible, move carpeting, furniture, and other vulnerable possessions away from the window area.
