Gravina's Window Center of Littleton
Home Window Replacement Companies in Thornton
Average rating: 5 out of 5 starsJune 18, 2015
“This is the second window-replacement project Gravina's Window Center has completed for me. The first was in 2009 and based on my total satisfaction with that job I used them again earlier this year for the remaining windows in my home. Every person at Gravina's was without fail extremely professional, friendly, competent, respectful and very careful inside my home during the installation. I particularly enjoyed working with a local family-owned business. I recommend Gravina's Window Center without reservation to anyone seeking high quality windows, flawless installation and top-notch service.”
Egress Inc
Home Window Replacement Companies in Thornton
Average rating: 5 out of 5 starsMay 15, 2024
“I cannot speak highly enough about this company. They were very prompt in responding over email and JC the owner and Cody came out to quote within 24 hours when I needed a response quickly for a real estate transaction. These guys could not figure out why the current egress windows weren't working and worked hard to figure it out. FOR FREE!! Walked away without giving us a quote to replace the windows but fixed the issue on the spot. Kind, courteous, clean and such a high level of service. You just don't get this kind of service from most companies any more. They will be my first call and only call any time I need egress window support. Thank you again, JC and Cody! We appreciated your great service today!”
Skylight Specialists, Inc.
Home Window Replacement Companies in Thornton
Average rating: 5 out of 5 starsMarch 28, 2016
“I had Skylight Specialists replace four operable (leaking) skylights over a year ago. Their estimate was far less than several others I also considered. They recommended the inoperable skylights because I hardly ever opened the 18 year old ones anyway. They also recommended buying new ones as opposed to repairing the installation parts of the old ones that were what was leaking. They explained that for just a little more money (an additional $2000 I would get new inoperable skylights with a great warranty rather than reinstalling the old ones that they could only warrant the installation but not the almost worn out old ones. I agreed with their evaluation, realizing that I'd probably have at least one of the old skylights fail and need replaced within 3-5 years and would pay enough at that time to replace the old one to be even with what they wreaking me to spend for all new ones at that present time and... I would still have three old worn out skylights to worry about leaking and requiring replacement!! Skylight Specialists installed all four in less than a day, gave me a great written warranty and a great price, and best... they haven't leaked a drop! I'm very happy with Skylight Specialists, would readily use their services again and highly recommend them to whoever is looking! Tom S.”

Mountain View Window & Door
Home Window Replacement Companies in Thornton
Average rating: 5 out of 5 starsMarch 29, 2013
“I am a contractor and purchased quality windows from Mountain View Window and Door company and hired them to install for my remodel project. They are a new supplier for me and are very friendly and timely in their quotes and ordering, as well as providing a professional and friendly installation team. I also purchased interior doors from them which I had my own trim team install. I will work with them on upcoming orders in the near future.”

Zen Windows Denver
Home Window Replacement Companies in Thornton
Average rating: 5 out of 5 starsMarch 21, 2014
“I could not be happier with the experience I've had with Brandon and Zen Windows. I had to have a severely cracked window replaced on the second floor of my house, and Zen did the job beautifully. The timeliness, courtesy, experience and professionalism simply can't be beat. Add in the fact that Brandon and Zen did the job for literally hundreds of dollars less than the competition was quoting, and I can say that I'll probably not even look at another company for the next time I need a replacement. Thanks Zen!”
