Faulty Window Installation: Signs You Need to Look For

When you buy new windows and have them installed by the pros, you expect the job to be done the right way. However, the benefits of these purchases, from improved aesthetics to better functionality, can be completely negated if they’re not installed correctly. Apart from being a waste of finances, poorly-installed windows could lead to water damage and other problems that could compromise your home’s structural integrity.

Window installation

Read on as we discuss the signs you need to look for that can indicate faulty window installation.

Window Operation Difficulties

New windows should operate without a hitch. After the installation is finished, make sure to test them. Do they open or close properly? Are you having difficulty doing either one? If not addressed right away, these issues could become worse until you are left with windows that are rendered useless.

Substandard Appearance

New windows should appear perfectly leveled without any noticeable gaps. Also, the glass should look clean and without a single smudge. Inform your installer if you notice any of these problems on your replacement windows following the installation.

Hasty Caulking

The caulk surrounding the window units is their first line of defense against the weather. If it fails, water could find its way inside your home through cracks and gaps. Make sure that the applied caulk looks smooth and even. If it doesn’t, the installer is likely to have cut corners for the entirety of the window installation.

"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
