After having experiencing contractors in the past that had left us feeling frustrated, disappointed and taken advantage of… It has been a breath of fresh air to work with Gravina’s Window Center of Littleton.

At Gravina’s Window Center, our number one goal is to exceed our customers’ expectations. We’re proud to share our customers’ testimonials of the Gravina’s window family experience. 


After having experiencing contractors in the past that had left us feeling frustrated, disappointed and taken advantage of… It has been a breath of fresh air to work with Gravina’s Window Center of Littleton. We had tried going the route of “finding a great deal” in the past, only to discover cheap is expensive in the long run, and our “deals” had left us with poor quality products and even worse quality workmanship. We decided this time around we would research and interview for all of the projects we were about to begin – this time it would be about finding the best value for our money, professionalism, quality and workmanship.


Our first meeting with Gravina’s was to look into replacing a few basement windows. After meeting with Jim Gravina, Mike and Justin Shyong – loving their energy, knowledge and ideas – we decided to have them replace the windows in the basement and replace our back-patio doors. I can’t begin to express how excited we were to see the finished project – the back door had become a favorite focal point of our home! Once we had actually seen, and experienced the difference with the windows, door and workmanship from Gravina’s, it was a “no-brainer” to have them handle “phase two” … siding our garage and replacing the garage windows. Again, everything was awesome! Knowing that our James Hardy siding was done according to all of the proper guidelines of the product was important to us. Of course, with everything going better than we could have expected, I can honestly say, we were excited to hire Gravina’s again for “phase three” … replacing the windows and front entry door on our main level (the remainder of the house), they continued to exceed our expectations and we are absolutely ecstatic about everything! John Gravina and his crew did an incredible job with our window & door installation, as well as Wynette & Samantha who had come back to do perfect staining of the interior windows, door and casings to match the hardwood floors in our home.


It seems a little strange to say I was excited to work with a contractor – because I think many of us have experienced that nightmare of having someone in your home and just praying for the day they will leave – but the peace of mind knowing that things are going to be completed right, all of the proper follow thru will be done, having qualified and respectful people working in your home, knowing that you have a company you can trust, and knowing you will have beautiful windows, doors and siding to enjoy for years to come, is something to be excited about!


Upon writing this review, I have reached out to Gravina’s to let them know if they have a client that would like to see the work they have performed at our home, they are welcome to schedule a time with me to bring them by (this is something that we have only offered to do with Gravina’s and Luxescapes, the landscape/hardscape company we worked with on our backyard that was also incredible). Because I don’t want to post my personal contact information over the internet, if you wish to call me regarding our experience with Gravina’s, you are welcome to get my number from Gravina’s.


If you are looking for windows, doors or siding, I would highly recommend contacting Jim, Mike or Justin to come by… you will not be disappointed!


We hope you will find this information helpful in your search for a qualified contractor for your project!

Gravina's installed a top quality Marvin sliding patio door. The installation was outstanding. The interior and exterior finishes were matched exactly. This is the second patio door we have purchased from Gravinas. The first was several years ago. In both cases , they did an outstanding job. I recommended them to my nephew and they replaced several of his windows which were damaged by hail. He was completely satisfied and has ordered more windows from Gravinas of Littleton.

Gravina's products and the service were excellent. The new windows are much better than the windows they replaced. They are keeping the warmth in the room and I can see they will keep the heat out in the summer which will be a blessing. The young man who did the the job was prompt, polite and did his work with the minimum amount of disruption. I would highly recommend Gravina's to anyone who needs windows replaced.

The Gravina's technician that installed the door was outstanding. He worked several hours on Christmas Eve to get it finished. He was very professional and we were very happy with the job he did. The weather was an issue for the painter because it was an exterior door. She persisted until she was able to complete the work and she, too, did a good job. Overall, we are very happy with the work that was done and the quality of the product.

We ordered 4 patio doors with wood pane inserts, 1 single door with bronze pane dividers between the window and about 22 casement windows in custom sizes with wood panes. The doors and windows were produced by Marvin Windows. We purchased them through Gravina's in Littleton, CO. The approximate price was $70K. Our old windows and doors were removed, and the new windows and doors were installed by Bill, and Wynette (staining). The workmanship was outstanding! The installers were friendly and very professional. It was clear that they took pride in their work. Due to our travel schedule, a good amount of the work was done while we were out of state. I felt completely comfortable letting the installers continue working while we were away. When I returned, it was clear that they had taken great precautions not to damage any paintings or furniture during installation. They also cleaned up the areas where the installation occurred. There was one glitch and that was the single door in the kitchen. The manufacturer had placed a white divider between the glass instead of a bronze pane divider. The error was brought up to Jim Gravina who called the manufacturer and requested a new glass insert with a bronze divider. The new window was installed AND instead of just a bronze divider between the glass, Lonnie installed wood inserts that were placed on the outside of the window covering the bronze divider on both sides of the window. The wood inserts for the single door will be stained to match the wood dividers on the interior face of the casement windows and painted white on the outside to match the exterior side of the door. That was totally unexpected but VERY MUCH APPRECIATED!! The resulting is a top notch company. When I am ready to replace several additional windows, it will definitely be through Gravina's.

Gravina's installed 4 windows and a patio sliding door. They are Marvin Windows which are great. They measure to fit the window. Their installers wants to make sure everything is perfect. Their attention to detail is excellent. I recommend them to others.
