What Your Neighbors Are Saying

Frank and Fred were very professional, friendly & courteous. They worked quickly & efficiently when installing 4 windows and a set of sliding glass doors. Very nice job
Cathy & Ernie D.
I hired Window World for an installation of three extremely large slider windows. These are windows other companies said could not be done. After finding their prices very reasonable, I asked for a quote on a garden window. Super price so I went with that also. It too was very large, almost pushing the limits on max size. The windows were installed over the course of a day and a half, and the installers exceeded my expectations in every way, as did the quality of the windows! I highly recommend them to anyone!
Anne F.
Installation was quick and clean. The window was easy to access both inside and outside with no climbing needed, so that probably helped with it being convenient. The two installers were kind, polite and I was comfortable with them (and they made a fuss over my dog). We will only use Window World in the future!
