I had a sliding glass door put in by Terry's. They were superior to ALL other companies I have ever worked with! The work done was fantastic! The price was great, salespeople are very knowledgeable and the installers were friendly and professional. I can't stress enough just how wonderful the whole experience was for me. I will never use another company for my window needs again! Terry and his staff are the BEST!

The windows are fantastic! A+ to The Team at Terry's Discount windows From the first phone call to the installing they made it so easier. On installation day the crew was very professional and very meticulous in their installation. We had three windows installed and they did an awesome job. Wish I could give 10 Stars.

Critical: Professionalism Salesman came out to give me a quote on my windows and he was very rude. Told me a price is good for 2 days and price goes up 3,000 dollar in 2 days. Very poor salesman. Interested in getting windows but need a better salesman to give me time to talk with wife about price.

Our home is so BEAUTIFUL and QUIET now! We recently had our siding, soffit, fascia, gutters and patio door installed by Terry's. We are so pleased! Walking into the showroom at Terry's is like walking into a room of friends, I have never felt so welcomed! We chose Terry's based on their being a local family owned and operated business, our past experience with them replacing a couple of windows and their price was reasonable and competitive.
As for the timing of our install, besides the slowed manufacturing of the products (which is not in their control) they were quick and courteous once the supplies showed up. I highly recommend Terry's Discount Windows from our experience!

Wow. Terry's Discount Windows is amazing. These Windows (4 were installed) look great. Both the inside and outside look transformed. The reason I had them replaced is because they were from 1951 and were crank single pane that would not even close all the way. The new Windows make a huge difference. I heard about Terrys on the radio. Since they are a Christian company I knew I could trust them. And I was right. The installers did a fantastic job in 10 degree weather. If you need Windows, you can trust Terrys. AMAZING!

Terry's was recommended to us by a relative who had a great experience - and they didn't disappoint. We've had 3 windows and two exterior doors replaced so far, and both installations went without a hitch. Their crews are super professional, they work neat and clean, it's affordable with competitive pricing, and their work is flawless. We already have our next job with them lined up and at least one more after that we're brainstorming. Terry's is the best!
