CM Shepard Construction Inc.
Longmont, CO Window Contractors
February 10, 2021
I can and have highly recommended the CM Shepard Construction Company to many of my friends. All of them have used this company and have made a point to thank me for suggesting them. They all had a good experience too. The workers were good to give us a schedule and they stayed true to it the entire project time. They were polite and kind. They were good to protect our property. They made sure the lawn was not damaged, which was important to my husband. They kept my house clean and neat which was important to me. We were happy with the work they did and with the product we now have. I cannot say enough good things about them.

It took a few weeks to get everything going, but the guys at 5280 Exteriors are awesome. They're respectful, and informative, and you, in no way, feel slighted or as though they are attempting to take advantage of you. LOVE THESE GUYS!!!
Skylight Specialists, Inc.
Longmont, CO Window Contractors
March 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
Longmont, CO Window Contractors
March 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.
Abraxis Art Glass & Doors, Inc
Longmont, CO Window Contractors
November 9, 2015
Services provided by Abraxis in my opinion have been the very best that i could have expected. i have had conducted business with Abraxis on a professional and personal nature. As a project manager, Abraxis was always willing to step up to the table with their best price and service. Personally, i was involved in a project where Abraxis was consulted and hired to fabricate and install some of the best stained glass artwork i have seen in a long time. Products, service and professionalism are over the top!
Gravina's Window Center of Littleton
Longmont, CO Window Contractors
June 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.

We just had all our windows replaced. The crew came and was very respectful of my time and working in the house. They finished all 25 25 windows and 2 doors in 1 day. They cleaned up and made sure all my questions were answered. I really love our new windows. Kristen and Joel Carrollton tx.
