I recently got a couple of storm shutters installed by Gill Window. They were custom made for my windows. I think they are terrific. Highly recommended!

We had all 12 of our upstairs windows replaced with Gill Windows. Then a couple years later had the main entry door, the rear entry door and two storm doors replaced by Gill. If I could give these guys a 10 star rating it would be low. We had a bay window built by Gill windows and totally replaced as well. About two years after the window replacements, and because I'm admittedly not the sharpest knife in the drawer, we didn't have the closure mechanism properly closed on one of our larger windows on the side of the house that catches the most wind. Well, I called Joy, Dwayne comes out and within two minutes very politely showed me the problem and then wouldn't take a service call payment.

Every single person I dealt with at The Gill Window Company simply rocks. Forgot to mention we live east of town on Windbreak Road. Seriously. The wind blows constantly. The windows are great. And yes, it really helped with our energy costs as well. A tried and true local company that is an example of trade locally. Try to get a Denver company back up here to service your product. Have been and will continue to recommend The Gill Window Company. Tom Reid 5669 Windbreak Drive Cheyenne.

The Gill window company receives the highest recommendation from me. They have quality windows, that I have had for years. If you do need assistance from their company, they are happy to come and solve the problem., and go out of their way, to accommodate. Mike is absolutely one of the nicest people, I have encountered. Thank you

Gill windows are the best company too work with, I bought windows for my whole new house went to pick them up and didn't have a big enough rental truck Mike said no problem and helped me get a bigger truck and with a large order little things pop up and again Mike was always spot on with resolving all and any issues that I had. Now it's been 13 years from the order and my windows are holding up in the Arizona brutal sun with little care a good quality product at Gill windows, I must say all the employees at Gill windows are great and were a big help from start too finish. I wonder if Mike remembers, he does have a lot of customers, thanks again to all the great people at Gill windows, later Will

If there's a better window company around I'd be surprised. Duane and his crew installed windows at my house and I couldn't be happier. From Joy the receptionist, to Chuck and of course Duane and his crew of efficient, hard working professional and excellent customer service staff were terrific. I will recommend them to everybody I can. It was a pleasure doing business with them. They are true craftsmen!

We bought our windows when Kevin was alive and if anything went wrong he would always make things right! They were supposed to be guaranteed for life. Since he has passed on this is not the case anymore. We had to have the window in the downstairs bathroom replaced because the seal broke (second window this has happened to). The young gentleman (Mike) that did the work was awesome but the bill was $20 higher than the estimate because we were charged for mileage, which we never had to pay for before. Very disappointing and we will have trouble recommending Gill Windows to anyone.

This company and its employees are phenomenal. They have been helpful and on top of their game from the moment I called for an estimate. They came the next day to measure and gave me a quote on the spot. It only took a few weeks to get the windows installed once ordered. Their staff was very courteous and professional when they installed 3 windows today, in the snow and cold to boot. They left zero mess, were timely with the install and did a great job. I will use them for any and all future window needs.

During our renovation we had all new windows put in our house. They came over and did all the measurements and came over to install them as soon as they came in. They even added a larger window sill for me in my kitchen! I couldn't have asked for a better group of workers! Thank you Gill Windows for all your hard work!

We had our windows installed today by Duane and his crew. They were very professional, cleaned up their jobsite, didn't let my dogs out. I couldn't be happier with the installation. The house already feels tons warmer! The custom made bay window is gorgeous! The natural oak frame is beautiful and can be stained. The windows open easily for cleaning. Im so tickled! Will definitely call them to replace the front door!

Last summer (2014) we had Gill make us 6 patio doors and a large window. We had all of the doors installed around our porch, which effectively gave us a sun room that we could enjoy year round, and allows us to control the air flow through the porch area regardless of the wind direction or force, which is a key factor here in Wyoming! We have found these doors to be flawlessly constructed and absolutely windproof.

These were important considerations since we like to sit out on the porch and watch nature's fury and her beauty during the winter and summer months. We could have gotten less expensive patio doors at one of the giant home improvement chains, but we could not have gotten the same degree of quality construction or personal attention to our needs. Highly recommend Gill for custom doors and windows that are 2nd to none!

I never had a window installed by Gill, but I had scheduled a free estimate with them in regards to a window I had downstairs that was leaking water. They took the extra time to pinpoint the real source of the water, which was actually a small part in my kitchen sink. They could have told me that I needed a new window and I wouldn't have known any better. I was very thankful for their time and their honesty. They didn't even seem bothered that they didn't profit off of me, but I was very thankful.

I had Gill windows installed at my house the better part of 15 years ago. It was a good experience and I've never had a complaint about the process or the product. This week the lock on the patio door broke, so I called them to fix it. The guy arrived exactly on time and fixed the lock quickly. Then he refused payment! What company do you know that will repair for free 15 years after purchase? A quality company.
