We think we're pretty great.
But don't just take our word for it.

See what some of our customers have to say about their Gravina’s installation experience.

“I love my new windows and doors! The installers were professional and friendly, and the quality is great.”

- Jessica Palmer

I love my new windows and doors! The installers were professional and friendly. The quality is great. They were able to recommend windows to meet my needs. The project was completed, on-time and according to the schedule that was communicated. I will be happy to use Gravina’s again in the future.

“Gravina's did a stellar job. They have superb customer service and they took extra time to make everything perfect.”

- O.C. O'Connell

Gravina’s Windows & Siding (@ 950 W Evans!) did a stellar job for us from consultation through installation! They have superb customer service & a passion for finding the most elegant solutions for complex situations. Our house had a jumble of casement windows, sliding glass doors and slider windows that were installed in the 1960’s and 70’s. Nick Gravina explored a wide variety of options for us to consider, taking into account our aesthetic and budget and delivered an outstanding set of windows and doors!

The installation team was led by Matt Gravina and they were exceptionally competent & kind. Because of the age of some of our doors, getting the new doors plumb and level required some creative problem solving and a lot of persistence. They took the extra time to nail it perfectly!

If you are in the market for any kind of replacement windows or doors, I cannot recommend Gravina‘s highly enough. There are two parts to any successful replacement window project: choosing the correct windows and having a top-notch installation crew. Gravina‘s exceeded my expectations in both regards. Moreover, they were tidy, on time and cleaned up after themselves. They had a lot of respect for us, our home and our dog!

“I needed a simple window repair. I was greeted right away, and my window was fixed on the spot. Thanks so much! We will be back!”

- Stefanie McDowell

Walked into Gravina’s this morning with a window needing repair.
I did not know who installed our windows originally, but decided to try. I was greeted right away and my window was fixed on the spot.
It had some missing and broken parts that would hold the window in place. They even showed me how to re-install the window while I was waiting.
Very friendly and did not even charge me which was a huge surprise and made my day! Thanks so much! We will be back!

“Our door was installed perfectly. Gravina‘s was on time, professional, and they did a great job. I highly recommend them!”

- Circe Baumgartner

We just moved into a new house I needed a new door installed before the painters started there job.Luckily Gravina was able to accommodate our request! The door was installed perfectly. Gravina‘s was on time professional and did a great job. I highly recommend them!

“I had the most awesome experience with Gravina's! Every person I dealt with was friendly and professional. I love my new door! Yay!”

- Kristen Ferguson

I had the most awesome experience with Gravinas! I needed a new front door and every person I dealt with was friendly and professional. From the reception staff, sales and installation, they communicated at every step and I love my new door! It was so great watching my old, janky front door removed and carted away. YAY!!!!

“Nick Gravina and his staff are the kind of people that you want to deal with when you need windows. Nick looked at what we needed, measured, and suggested great product for the application.”

- JE Carpender

Nick Gravina and his staff are the kind of people that you want to deal with when you need windows. Nick looked at what we needed, measured, and suggested great product for the application. When the windows came they were scheduled and installed at a time that worked best for us. Thank you Nick Gravina and all the staff at Gravina’s Windows for a job well done!

“I had the best experience all around. From the beginning the sales process was not high pressure, pricing was competitive, and product is great quality.”

- Shawn Fewell

I had the best experience all around. From the beginning the sales process was not high pressure, pricing was competitive, and product is great quality. The install process was painless, they even worked around my schedule to make it work best for us. Installer did a great job and made sure everything was perfect. I will use Gravina’s again for sure and will recommend them to anyone I know needing windows.

“I give my highest recommendation to Gravina’s Windows and Siding. The customer service goes above and beyond.”

- Judith Lev

I give my highest recommendation to Gravina’s Windows and Siding. The customer service goes above and beyond. I have Andersen casement windows and one of the window cranks was no longer opening the window. I don’t know where the windows were originally purchased. I called another window business that sells Andersen and is certified to do their repairs before contacting Gravina’s. That business tried to sell me new windows but did not respond to my numerous phone messages when I said I only wanted to deal with the one window opener. I later called Gravina’s Windows and Siding and explained the problem to Nick Gravina. He offered to come to my house and evaluate whether the crank could be fixed. He was never concerned that where the windows were purchased was unknown. He just knew I needed help and was willing to go out of his way to try and help me out. In the end, the opener needed to be replaced and Nick determined the correct part, ordered it, and installed it for me. I am so appreciative that I can use the window again and that Gravina’s was willing to do a job that they were not responsible for, but did because they had the expertise and wanted to help me out.

“We had a wonderful experience with Gravina’s Windows from start to finish.”

- William Gersch

We had a wonderful experience with Gravina’s Windows from start to finish. Top of the line workmanship and customer service with competitive pricing. We installed new windows upstairs, and we will be return customers when we are ready for new windows on the main floor.

“Gravina's was honest and professional and saved me a ton of money that other companies probably would've been happy to take!”

- Christy Naplin

Honest and professional and saved me a ton of money that other companies probably would’ve been happy to take! I was concerned that my windows may have needed to be replaced, but Nick came by and recommended replacing only one glass pane that had a bad seal. He ordered the glass and installed it in about 20 minutes, and it looks amazing! What could’ve cost me thousands ended up being a cheap, easy fix. They weren’t interested in selling me windows that I didn’t need, but I will absolutely be calling Gravina’s when I do!

“Everyone at Gravina's was very professional, and prompt. I recommend them to anyone without hesitation!”

- Michael Gooseff

I have used Gravina’s to replace windows in two homes in Colorado and I LOVE their windows. This time around we went with triple panes and they have been fantastic this winter. Everyone we worked with from planning to installing were very professional, prompt and clear communicators. I recommend them to anyone without hesitation!

“We are very pleased with Gravinas! Our new windows and doors are beautiful. Gravina's went above and beyond! Highly recommended.”

- Terri Dahl

We are very pleased with Gravinas! Our new windows (9), doors (3), and storm doors (2) are beautiful! When ordering, they answered all our questions. The products we received were quality materials. The installation was meticulously completed with care. Above and beyond! Highly recommended.

“They are professional, easy to work with, and tidy. The price is fair, too.”

- Denise Taylor

We have been working with Gravina’s for years. Since we moved into our house, they have done all of our window replacements, siding for gables and front of house and a brand new door. They are professional, easy to work with and tidy. The price is fair, too. I plan to continue to work with Gravina’s and have recommended them to family and friends.

“Amazing quality. The entire experience was great! They presented us with many options and delivered an amazing finished product.”

- Brian Bugge

Amazing quality. the entire experience was great they presented us with many options, stayed in touch about timelines, and delivered an amazing finished product. our new siding looks great and all our neighbors comment on it.

“Nick and his team were extremely helpful with finding and ordering the correct screens for our older windows.”

- Kevin Brenninkmeijer

Nick and his team were extremely helpful with finding and ordering the correct screens for our older windows. Will be using them in the future for window replacement projects.

“Having a contractor background myself I know the importance of selecting the right company, the right product and what is truly the best value.”

- Chuck Boncordo

Having a contractor background myself I know the importance of selecting the right company, the right product and what is truly the best value. Value does not mean the lowest price but the price was also great at Gravins’s. We worked directly with Nick Gravina and from day one we knew he stood well above the competitor’s Slick Johnny’s sales reps. We had 14 residential windows replaced in 2 days by a team of only 2 men. Jeremy and Ryan were awesome. I would guess that Jeremy is probably one of the best installers in the Rocky Mountain Region.

We highly recommend Gravina’s and would use them again w/o shopping further. We made the right choice by selecting Gravina’s.

“We had Gravina's come turn our kitchen window into a sliding patio door, which involved cutting into our brick siding and filling in our old back door with matching brick.”

- Sarah Foley

We had Gravina’s come turn our kitchen window into a sliding patio door, which involved cutting into our brick siding and filling in our old back door with matching brick. Joe was here on time every day, was very communicative and friendly. The project took a little longer than anticipated (due COVID and some other unforeseen circumstances) but Nick made us feel very taken care of and the team truly bent over backwards for us. Our new patio door is our favorite part of our home. Will definitely call them again.

“Nick and his team were awesome! They helped me out with 2 different window projects.”

- Joel Miller

Nick and his team were awesome! They helped me out with 2 different window projects. I’ve been very impressed with the level of service and professionalism. Great company to work with.
