I had to call/email several times to check on the progress of my windows and other work.

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.

Very professional, high quality product, super happy.

Very helpful, courteous and knowledgeable staff from the showroom through the install. They carry very nice quality products at a very reasonable price.

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.

They worked with us when we have some extenuating circumstances. They have a wonderful customer service.

We are long time satisfied customers.

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.

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.

The quality of installation and professionalism was very good.

Gravina's Window Center has fantastic windows.

They are a very professional company with a great quality of workmanship and we are satisfied with the finished product.

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.

Windows are excellent. Gravina's has a very professional and family feel to their organization. Will happily use them again for the next project.

Gravina's Windows are saving us on electric and gas bills. We appreciate this as we are on a limited budget. Regards, John and Connie Martinez

Every aspect of my sliding glass door purchase and installation was handled professionally. I highly recommend Gravina’s.

Gravina's of Littleton answers all questions, helps with any problems, is punctual - great customer service from beginning to end.

I was real happy with them, and I'll use them again. I was happy with everything, from sitting down with them until finish.

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.

I am disappointed after paying that much money. I am disappointed in them doing their job correctly.

Gravina's Window Center of Littleton is very professional.

Areas Of Satisfaction

Areas Of Satisfaction - From start to finish. Crissy and Jon visualized and thoroughly described all aspects of the work. This was not just replacement of a window and door, it was a construction project.

Recognized Excellence

Recognized Excellence - Everyone on our job, from start to finish was phenomenal

Recognized Excellence

Recognized Excellence - Thanks to Jeff & Tim for their excellent service and explanation of the entire window process. My windows were in bad shape and they were truly transformed with your install.

Additional Comments

Additional Comments - Thanks for an excellent job from start to finish. I will be returning for new doors soon. I like the fact that they do not subcontract their work out. Install team was highly skilled.

They did exceptional work. The windows look very good and very professional.

Areas Of Satisfaction

Areas Of Satisfaction - I think the result of the new windows was even better than I could imagine. It's so hard deciding on a window how it'll look. I had inserts on one window I took off, and it was the best decision. The quality is good, and the recommendation. It was hard to visualize how it looks, but the end result was great.

Additional Comments

Additional Comments - It's just a pleasure, even though it took some time from the time of signing to install it. It was worth the wait--I was very pleased with the outcome.

The new patio door is beautiful and the installation crew was great - neat, clean & professional.

We can walk from one end of the house to the other with little temperature change. It will be so much easier keeping the windows clean. We love our new windows!!

The employees at Gravina's were the most friendly and considerate I've ever encountered, especially for a project of this size. They took great care to protect our home and belongings from the installation process, and the Marvin windows are great. Thanks to Gravina's for making this large project go so smoothly!

Best quality windows, installation went great, my favorite windows ever, Peter Boyles was right.

We have recommended them to people who are looking to put in new windows and doors.

Jim and team are the best of the best!! They did a great install!!

They did everything very professionally. They insisted that I give them clear instructions about what I wanted. When I made a change in one of the windows, they did it in the snap of a finger. It was supposed to take 3 months to get the regular picture windows and it had been less than a month when I called them and told them that I wanted to change it to a box bay window. They did it and never missed a beat. I think that they are great.

The installers of Gravina's were very professional and friendly.

Absolutely excellent service and product (Marvin Infinity)... just need to accept the cost.

Great experience, highly recommended.

The people were really nice and helpful, but we were disappointed with the quality of the door. Hopefully, we can resolve this issue soon.

I had purchased some windows from Replacement By Anderson and decided to complete my home project with Marvin Windows. They were a little less expensive and I see no difference in the quality.

We were happy with the service.

They did a great job, easy to work with!

They do a good job and they follow through with getting things resolved.

They were just very easy to work with. We loved the finished product.

They did a great job. The windows look and function great. You can really tell the difference inside on the house temperatures. And with the windows were got; cleaning is a really simple and fast.

Gravina's Window Center was recommended by another locally owned business. I have been satisfied with both.Already I am noticing other windows in the house and am wondering why I did not have them replaced as well.Thank you again. I can open my sliding doors without calling my neighbors for help.

Recognized Excellence

Recognized Excellence - Jim Gravina is very easy to deal with, answers every question and helps you make the right decisions. The entire staff is there to assist if anything seems not quite right. We feel very comfortable dealing with Gravina’s and they will be our only call when we replace our front entry.

I didn't have a huge project, but nevertheless the owners of the company were involved in every phase of the project from pre-sale quotes, measurements, to inspecting the work that their installers had done (not that it needed any quality verification, all of their staff is excellent) . I wouldn't hesitate to recommend them to friends or use them again.

Areas Of Satisfaction

Areas Of Satisfaction - They kept every commitment that they made and their prices were extremely competitive for higher quality windows than some of the other firms that compete with them

No doubt in my mind, I will always call Gravina's for any work in the future!!!!

The installation team was outstanding. Unfortunately Gravina's and Marvin have not, over the course of year, been able to resolve poor quality screening issues on the largest of the windows in my project.

We get so many positive comments from our neighbors about our new siding! We are very pleased.
