  • Dani Brown is a awesome project manager. She came out tonight explained everything, went over all the different style windows with us and the installation procedures. Great lady to deal with , we can’t wait to speak with her again!!

  • Ryan was our salesman today and was not planning on buying windows today. We like to shop around and make sure we are getting the best deal for our money. After listening to Ryan and seeing the window and him working with us to get us the best deal he could, we decided to buy today. I feel good about it and replacing our builder grade windows is overdue. Thanks for all your help Ryan and can’t wait for them to get installed!!!!

  • job was done as promised and done right the first time. 12 windows installed in one day.

    We had David come to our home the other evening and quote us for new windows which we terribly terribly need, our home was built in the 1890’s and the windows at least down stairs are probably still from the early 1900’s. No joke. And we have 20 windows in our home. We have decided to just do the 13 down stair windows for now, But I am extremely impressed with David as he was very knowledgeable and gave us a lot of useful information. He was very polite and kind to our children! We look forward to working with this company and the improvement it will make on our home!

    25 windows installed in one day by a crew of 5. Wow! Job well done. The crew worked exceptionally well together, and were organized and efficient. The windows are terrific and have already noticed a decrease in the heat when by the window. Cleaning of windows is not included in contract, but I expected at least the greasy handprints be removed.

  • John D. presentation was very professional. We are thrilled to get our new windows to be installed ASAP. Will recommend John to all our neighbors and friends. Thanks again, greatly appreciated. Oleg and Elena.
