Testimonials

Hello, My name is Jill Hebert, we recently were in the market for new vinyl replacement windows. To our surprise TDWS had a lot of good ideas for our home and brought up good points that other companies didn't even mention. Then when he gave us the price, I couldn't hold back my tears I was so happy. TDWS contacted us at least five times after we signed the contract and before our windows were installed! The Door & Window Specialists did a beautiful job on my home, They had all the windows installed in one day, They left my home clean, I can't hear the freeway anymore, The windows are a lot easier to slide, The house stays cooler, etc. I hope that if you are considering buying windows for your home that you would have TDWS perform for you.
