Windows Installation in Denver

“If you're looking for window installation, then I highly recommend that you don't look past 303 Windows. We moved into a house with 30 year old windows, and knew they needed to be redone. We contacted three other companies, each of which spent at least two hours walking through the house, measuring everything, and inspecting every detail, only to sit us down afterward and present outrageously high quotes, with added pressure to buy right away, and offering discounts if we did x, y, or z.

After reading great reviews about 303 Windows, I decided to contact them. Honestly, the reviews undersold how great they are. Jay came out and completed the entire walkthrough in about 20 minutes. He immediately pointed out all the issues the other companies had mentioned, and then some. You can tell he truly knows windows. His quote was less than half of the national brand we had talked to, and much less than the other two companies. He even mentioned our problem windows, that no other company had bothered to note, because they were high living room windows, that couldn't be accessed without a ladder. He also mentioned that we could save some money by not having grids on the windows. None of the companies we spoke with even mentioned that. He didn't try to push us into signing that day or up sell, or anything that made us feel like we had to buy right away. Jay was very patient with all of our questions and made us feel heard. He said no job was too small for them, and we could do a few windows at a time. Given how great his quote was, we decided to get everything done at once.

Jay's sons and crew handled the window installations, and they were fantastic. They finished almost 30 windows in two days. They also fixed some of our broken window sills, window trims that had rotted over time, and repainted everything. They were very considerate, and cleaned up after themselves. Jake and Max were especially great. They were friendly, professional, and clear about the few minor issues that came up, while patiently answering all of our questions. I've recommended 303 Windows to our realtor, neighbors, and will 100% be using them in the future if we ever have any window issues.

Even if you need to fix only a window or two, contact Jay. You will not be disappointed. Thank you guys for making our house a little more beautiful!“

“The bid I received was not only very competitive, it was very professional. In particular, I appreciated listing references I could call, which I did.

And the roofing job itself was excellent. Not only did they do a great job in a very short period of time, they went out of their way to do a new roof on an entry arch. I had not planned to re-roof. But I’m glad they did.“

“Amazing company! I had a stuck window and Nancy was very helpful over the phone and sent over a technician, Anthony, who helped open the window up. Very professional.“

“Quick, easy and courteous. Have used them twice and will continue for all out glass needs!“

“I ended up getting 11 windows installed at my home, he was responsive and professional during the entirety of the project. He did a great job with the small details and they look great. Very reasonably priced and polite.Service: Window installation“

“I waited a full year to write this review so that it could be as complete as possible.

The sales experience: Excellent. James was great to work with and went above and beyond to meet me at a showroom where I could have a better look at the windows than the small sample. The quote was more than competitive and it was a straightforward interaction without the sales tactics I saw from other companies.

The installation: Very smooth. The crew was experienced, worked well together and efficiently and did an excellent job with no residual issues.

The windows: I love them. I have lived with them (Simonton windows) for a year and they are beautiful, work well, and are easy to clean. My husband has been tracking our energy usage and our natural gas bills were significantly reduced last winter after replacing with these windows.“

“After a big hail storm, we worked with Jesse to replace our roof. He did a great job of working with us and our insurance provider. Everything was handled professionally, and our new roof looks great!“

“Great service - I called and they were able to come out and fix our shop door same day - and it looks great! Fair price too and very nice gentlemen. Stay glassy guys.“

“Ralph is amazing! Outstanding customer service, great price! So appreciate the work S&H did!“

“Big thanks! R&R had a clutch shoe for windows 30+ years old. Better, R&R had pictures on the internet that I found using Google Lens - 1st time! I thought I would be looking for hours trying to find this old shoe. R&R parts was 100% like the 30+ year old shoe. Plus, very good price and free shipping. 5 Stars. Thanks!“

“We were very impressed and extremely satisfied with the deck from the Install Company. The communication was top notch with Mark and Bronn. From start to finish we were kept in the loop and our questions and concerns were addressed promptly. We love how our deck looks and can't say enough good things about our experience.“

“I had a unfortunate instance at my house. I called Colorado Glass and Mirror LLC.
They came out right away to help with the problem.
My windows were completely done in a week.
Justin and Xavier came out and did a great job

I totally love this company Colorado Glass and Mirror.

“Very encouraging through a long process with the insurance.
Great product and people.“

“I highly recommend this company. Great prices. High quality doors. Experienced and professional work crew. This company was easy to work with and delivered on-time and as promised. The workers are employed by this company so they know their crews and are accountable for the workmanship. They showed up when they said they would and did great work. The doors are really nice and solid. They did an excellent job all around.“

“So thrilled with our beautiful new door! Mike Cook was so helpful with getting us the right door for our home and Jesus (installer) was friendly and so professional. Cannot recommend them enough!“

“This is my 2nd time using Reflection windows and doors. Both times the service has been incredible. I highly recommend.
My 1st experience was repairing a sliding glass door. I have 4 panels that slide that open up the back of my house. They repaired my door in a matter of minutes. The 2nd service was replacing a window where the seal went bad. Josh was great about calling 1st and replaced my window in about an hour. The install went great and he did a great job making sure everything was clean when he was done.“

“Exteriors Now did a fabulous job repairing and replacing my gutters. Their teams work tirelessly, on hot days, in thunderstorms, and we polite efficient and cleaned up each day. I would hire them again (very reasonably priced) in a second.“

“I couldn’t be happier with service provided by this roofing company. From start to finish, Mike Tinker showed incredible persistence and professionalism. He made sure every detail was handled with care, kept me informed throughout the process. I highly recommend this company!“

“I would highly recommend Brian from Gravina's Service Department. He is very personable and has a great attitude. His expansive knowledge from decades in the business is very impressive and enabled him to promptly replace worn parts and adjust the windows. Thank you Brian.“

“Every project has its challenges and setbacks. When you select a contractor choose wisely. We recently hired Rocky Mountain Exteriors to replace siding, trim and paint the North side of our house. Right from the estimate, Conner developed a solid approach, communicated it clearly and sold it at a reasonable price (always get a few bids). Once the project started, Mason took over and scheduled the crews to complete the work. Again, clear communication and follow through. Javier's crew demoed and sided the house expertly. Impressive craftsmanship and an eye for detail. Although there was a rain delay in between, this was a setback. The trellis on our deck was a challenge. Javier came up with a creative solution in anchoring it to the trim. Eric handled the paint and was done in a day. Gutters went back up and the job was finished. I highly recommend RME and would rehire without concern. If you value communication and expect integrity you'll be pleasantly surprised.“

“They were fantastic and honest from start to finish. I appreciate all the help they provided and the professional nature. The window wells turned out great!“

“Roland and Andrew did an excellent job deliver and staging my new Pella windows in advance if the installation.“
