Our Reviews Speak for Themselves

Read glowing reviews from numerous customers who are now enjoying more energy-efficient homes.

“Our home has needed energy-efficient windows for years. We got the Ecotek windows installed. Wow what a game-changer! The new windows are airtight and cosmetically beautiful. We weren't sure that we could get a solid one-piece glass picture window because of its size, but we were able to do so and it is perfect! Because it had been several years and we had some shingle wear, we also opted for a new roof with Atlas shingles to top off the look. At this point, we considered purchasing new exterior doors. We were shown the Provia doors, they were so impressive that we opted for four new doors. We were not disappointed, they are beautiful. With the windows, doors and roof remodel it made the home complete! Would recommend this company to those ready for a home improvement project. ”

“We had doors, windows, siding and gutters installed throughout our home. Paul and his team were great to work with. He made several suggestions to not only save a few dollars here and there but also recommended different options on styles of windows available. From someone who knew very little about the project our home desperately needed, Paul and his team left me feeling confident and educated! I was very pleased with the installation crew and the doors and windows are excellent quality. We are extremely happy with the entire experience and end results with Wintek USA!!”

Carrington C.

“Having experience in home construction with charitable organizations, we knew there would be some industry delay in acquiring our replacement windows. The installation crew and Wintek's owner more than made up for this with their obvious concern for detail and satisfaction. They finished twelve windows in less than 9 hours, even making some minor modifications on site. Extremely pleased with the results!”

“Awesome experience with Wintek USA! From my meeting with two reps of the company to place an order..... to installation of the entry door, my experience was fabulous! I highly recommend Wintek USA for a replacement or new entry door. I love my new ProVia Door! It took me two years to find ProVia Doors and Wintek USA and I am glad I finally found both! You will not be sorry if you choose Wintek USA. I needed a replacement for an old wooden 32 year old door with sidelights and the installer (Tim) was able to make the new ProVia fiberglass door with sidelights look like it had always been there. Paul Echols was very responsive to all of my questions and concerns through the entire process! Great job!”
