Double-Hung Window Repair

Double-Hung Window Repair

Residential homes generally use four main types of windows; casement, awning, sliding, and double-hung. The latter is the most popular of the four, meaning that most people will need some sort of double-hung window repair at some point in their home ownership. Though most double-hung windows are made to last, there are a variety of issues that can affect their functionality.


If your double-hung windows are sticking, there could be any number of reasons for the issue. The simplest and most common is a hasty paint job. Double-hung windows have many moving parts that can easily be caught or stick when painted over.

Another reason for sticking may be the swelling, shrinking or general warping of the window itself. This can be due to frequent or sudden changes in warmth and humidity of the air.

Not Staying Open

Double-hung windows are designed to stay open after being lifted. If your windows are falling or slamming shut, the inner workings may need to be repaired.


You should be able to open your windows in nice weather, letting the cool breeze waft in. To the same extent, when the clouds roll in, you should be able to easily close the same windows, keeping moisture and pest insects at bay. If your window is leaking, there may be some warping or other issues keeping them from forming a tight seal. This can also be an issue that runs up your utility costs as the precious air conditioning or heat you’re paying for literally goes right out the window.
