See Why Maryland Heights Residents Love Window World

We had a great experience with Window World. We did 13 windows and a slider door. Very affordable windows that are of excellent quality. The install was done in one day, and everyone was professional and great to work with. I will definitely be referring Window World to friends and family. 10 out of 10.
Megan P.
From start to finish, Window World was A+ in our book. Pricing was straightforward with no hidden fees or extra charges. All the windows were constructed to specs – we had several specialty windows we needed. The construction crew was quick, efficient and friendly. They cleaned all the new windows inside and out, hauled away our old windows and cleaned up any construction debris. The lead installer explained the lifetime warranty and showed us how to operate the windows. 100% would recommend!

I had a great experience from quote to install. Every person I worked with was professional and knowledgeable. The quote was very reasonable and in line with the other quote I received. The work itself was done to specifications with no problems.
