Broken, Damaged, and Hard to Use

Your doors and windows should open and close with ease, so if they are difficult to use, it might be time to replace them!

It is so important to have easy to use, functional windows and doors—windows and doors that stick or won’t stay open is not only a nuisance, it is a safety hazard!
