Promar did an outstanding job replacing all new energy efficient windows and new siding. The crew on site were outstanding and the quality of the work is top-shelf. Their prices are very clear, as compared to other estimates - detailed and inclusive. Highly recommend!

The installers were very nice and fast. We purchased 22 new casement vinyl windows and new vinyl siding and it has transformed our home.

These guys are great. Reliable, professional, reasonably priced and experienced. Promar installed all new wood windows and aluminum gutters on my house and I can’t say enough good things about them. Our project resented a number of unique challenges and it came out better than new, on time and on budget because of their experience, professionalism and hard work.

We had all new energy efficient windows and 2 patio doors installed and the professionalism, workmanship, and knowledge were superb. The crews were always willing to listen to any of our questions or concerns. If we had to do it all over again, we wouldnt change a thing.

Wonderful experience. The team at Promar is top notch. My home needed new vinyl windows and Rick our rep came to our appointment on time and gave us an honest quote. I didn’t feel pressure to sign and appreciated not trying to be oversold. The customer service, smooth and clean installation, and professionalism is something to be admired by this local Wheaton business. It’s not a common site, and believe me, I’ve shopped around for Window companies.

Promar installed Marvin casement windows and new composite siding in 2 homes. The crew were professional and on time. They provided a straight forward quote with multiple options. It was a no pressure sale. I found the Promar quote to be competitive. The installation was on time and professional. I would highly recommend Promar.

I had new fiberglass windows and composite siding installed through Promar and have been totally happy with everything. They are highly professional and skilled. We have used them second times, now, and they have always done a terrific job.

Promar is a wonderful exterior company. Friendly and helpful. Always on time and installed all new casement windows and wood siding on the house. No pressure, just helpful. Love my new windows and siding! Thank you Promar!

These guys are fantastic! And they offer the best price for new cement siding and Marvin wood windows installed in my house. I have recommended them to all my neighbors. I had a least 4 other bids and Promar was the least expensive and they did amazing work.
