Keep in mind that even if you chose high-quality windows, they can still fail due to poor installation. This is why it’s important to hire a reliable contractor for your project.

Poor Operation

You should be able to open and close new windows with no issues. Make sure to test if your windows work fine following the installation. Check if it’s hard to open, close, and lock. If there are problems, you should let your installer know because when not fixed immediately, you can end up with inoperable windows. 


Many homeowners get new windows or sliding French doors to eliminate drafts or reduce energy loss. Once your new windows have been installed, you should immediately feel that the drafts are gone. Keep in mind that it’s not normal for new windows to be drafty. Let your window company know right away as soon as you feel moving breeze coming through your newly installed units.

When moisture seeps into your windows, mold and mildew can start to grow. These microorganisms aren’t only unsightly but also harmful to your health. You’ll water is seeping through your new windows when that the walls beneath and around the units are getting stained. Paint can also start to bubble and chip due to the excess moisture.
