Leaking Aluminum Windows

Aluminum windows are in many homes because they are inexpensive and relatively durable. These windows do contain a seal in the frame, which prevents water from leaking inside. If your aluminum windows are experiencing leaking, the problem likely lies with this frame seal. There’s no need to call the handyman, because you can remove and replace a damaged seal on your own.
