Testimonials

What Our Customers Say

Don't take our word for it — hear from Chicago homeowners who chose Newtec for their window and door projects.

"We replaced all 12 windows in our South Side bungalow and the difference is night and day. No more drafts in January, and the house looks completely updated. The crew was professional, on time, and left everything spotless."

"Newtec installed a new entry door for us and it completely changed the look of our home. The consultation was thorough, the pricing was fair, and they finished ahead of schedule. Highly recommend for anyone in the area."

"Our old sliding door was a nightmare — hard to open, drafts everywhere. Newtec replaced it with a smooth aluminum sliding door and now we actually use the patio again. Great value and excellent communication throughout."
