Window Leak Detection and Repair Tips

A window leak in your home can be a real nuisance. It’s something you might not even realize is happening until you realize that you’re spending a lot more on your utility costs over time. Leaks in and around your windows can be particularly diabolical because you are wasting money and they can cause serious damage to your home.

Why? Because a window leak can do more than let air out, it can also let water in from precipitation. The next time you have a serious downpour, the rain can also trickle into your home and cause some pretty bad water damage to your ceiling, your drywall, your flooring, and more.

That’s from just a little bit of water drip drip dripping in through a hairline fracture around the exterior of your window. The longer you allow that sort of thing to continue to happen, the more money it can cost in repairs and possibly even replacement expenses.

So, if you suspect you have a window leak, here are some ways to detect where it’s coming from and how to fix it.

Check the Frames

If you have a leak, it’s more than likely situated near the frame of the window. So, give the area a close inspection to find any gaps or fractures located where the frame and the wall meet. If you don’t find any cracks or gaps, don’t relent, you may not be finding them because you can’t see them, but they are still there.

This might require you to break out a magnifying glass and checking the entire perimeter up close. Get the magnifier up to the wall and observe the surrounding area closely. Go slow and look thoroughly.

Any luck? If not, you might need to try the window frame itself. Grip the side of the frame and see if you can shake it. Does it move? If so, even by a centimeter, you’ve found your leak. A window frame is not supposed to shift at all. So, if yours is shifting, you have a problem.

Fixing this problem could be as easy as getting some nails and caulk to secure the frame back into its seating. Just be mindful that you are re-installing the frame seated flush against the space in your exterior wall. If the window frame is not seated exactly level, then you will continue to have leaks.

Poor Functionality

Sometimes finding those leaks is a pretty easy. Your window just won’t shut fully or properly. Even the tiniest, miniscule millimeter width gap between the sash can lead to a significant amount of air lost. Perhaps the problem is even more obvious and one of your window panes has been cracked or broken. A busted pane of glass should always be repaired as fast as possible. This can pose all kinds of safety and security risks not to mention it brings down the curb appeal of your home.

Using anInfrared Thermometer

If it’s not a loose window frame or a malfunctioning or damaged window, your leak is elsewhere. Get an infrared thermometer to detect small adjustments in your air temperature around the windows. Notice any fluctuations? If so, you could be narrowing your search as to the location of your window leak.

Fixing the Problems

Depending on the type of leak you have, there are a few options for performing the right repair to deal with the issue.

New Weather-Stripping

If your window sash isn’t shutting all the way, add some weather-stripping to the edge and it can close the gap that exists and allowing air to escape and rain and snow to get in. This is an ideal solution for sliding doors that may be leaking as well. Fortunately, this is an easy and inexpensive fix.

Glazing the Windows

If a glass pane is giving you trouble and it’s not cracked or fractured, apply some new caulk to hold the pane in place. Caulk can deteriorate over time so your panes can come loose from time to time. Some new caulk will do the trick.

Window Replacement

Eventually it could come down to this. Your old windows are simply no good anymore and you need to put in brand new ones. You are probably thinking that you get no greater joy out of life than shopping for windows and it’s the last thing you want to do. But Andersen Windows, makes window buying easy and with so many new features and models on the market today, you’re bound to find the right window that fits your home.
