Gravina's Window Center of Littleton is very professional. The quality is superior. They are professional and clean up after themselves, and it was a great experience.

Thrilled with the service and installation was excellent.

I had to call/email several times to check on the progress of my windows and other work.
Dave H.
Our experience from in-home sales to installation was fabulous-very professional, informative, courteous and experts in the field, providing an excellent product. Extremely satisfied with our new storm door.

Gravina's was great to work with in spite of the "supply chain" long wait for the windows. Once they got here Gravina's was quick to set up an installation date with us that fit our schedule. The installers were clean and professional as well as being friendly and comfortable. The bedroom window was a simple job of remove the old and inset the new, but the bathroom window was a carpentry job as well. Tom spent an entire day, inside and outside of our second story bathroom, rebuilding, caulking and correcting the existing window opening on our 1897 house, before installing the new window. Now there are no air leaks, no whistling wind on a cold night. The windows are tight, firm and secure.
We chose Gravina's specifically because when making the original estimate they noticed the issue of the bathroom window and included it as a matter of course.
Gravina's is a wonderful group to work with. Their prices are competitive and their service is exemplary. Hire them, you won't be sorry.

The door is better than we expected the sales staff were very helpful.

Respective of individual requests and needs. Competent and friendly staff. Prompt attention to request for adjustment to the paint and screen at no extra charge. Professional communication and follow up. Customer focused from the initial consult to the post installation evaluation.

This is the second time Gravina's Window Center installed windows at our house. We called them again because they did a great job the first time. We are just as happy the second time.
Wendy F.
They worked with us when we have some extenuating circumstances. They have a wonderful customer service.
Pete S.
We are long time satisfied customers.
Review in Boulder, CO
I had a great experience with both the salespeople and the installation crew. The salespeople were very knowledgeable, had good advice, and gave me time to talk about what I wanted. The installation crew was efficient, informed me of what they needed, and made sure the house stayed clean during the install. Two of my neighbors also used Gravina's and were very happy with their experience as well.
Review in Littleton, CO
John the salesperson did everything late, called him a couple of times and never heard from John ever again. They assigned me to a new sales person named Wendy. Lack of communication mainly.

Gravina's of Littleton has worked on 3 homes for us in the past 20 years. We would not use another company for our custom windows & doors!

The owners, office staff and installation crew are tops. I am thrilled with the bay window they installed and amazed at how expert the installers were. Highly recommended.

Areas For Improvement
Areas For Improvement - They didn't really fall short. I don't fault them that it wasn't done on the timeline. They did it a month later, but I wasn't in a huge hurry, and I don't fault them for it. They communicated that to me, and I was fine with that.
Areas Of Satisfaction
Areas Of Satisfaction - I was definitely satisfied in the initial meeting with the crew. They were very through; like, they were honest. I like the whole family aspect. The crew came out to do the windows were extremely friendly, courteous, and did a great job. During the process, the initial meeting and going over the product--those two areas were exceptional.
Recognized Excellence
Recognized Excellence - I can't really think of anyone in particular. I remember the one lead guy on the crew, Tom. They were all great. Then at the initial meeting, John and Chrissy--the people I met with--I thought they were both great.
Toni S.
I am disappointed after paying that much money. I am disappointed in them doing their job correctly.
