The experience was excellent from the appraisal and measurement to the install. The product was delivered early and the installation crew was in and out in one day installing French doors, 2 side panels, andx3 exterior doors. Willxdefinitely call them again for future work.

Wow! Never thought my windows getting replaced would make such a huge difference in our home! Our windows were only about 10 years old! Unbelievable difference! I’m sure my heating costs are going to be much lower! If you need windows I recommend calling this company! I gathered a few quotes from larger companies and these guys blew the other quotes out of the water! Plus, the other companies could not even replace three of our windows because they said they were odd sizes. Window Source replaced all of them! Amazing job! I’m extremely impressed. Thanks!

I went on Saturday, morning and talked to Design Consultan Joe Bustos. He was very helpful and made some great recommendations about the different windows available. I was able to get an estimate, and will seriously consider The Window Source for replacing 29 windows. But, first I need to submit the documents need for HOA approval.

We are very happy with our new windows! You can really tell the difference from the original 1959 single pane windows. These new double hung windows are nice and clean. Great communication from start to finish. Definitely recommend 10/10
