Just completed windows and patio doors with Gravina's Window Center of Littleton. If you are looking for a great window company - look no further. They are not the snappiest in turn-around but the Attention to detail in the install, craftmanship and overall working with them was an outstanding experience. Glad we chose them.

We Couldn’t be happier with Gravina’s and our experience replacing our entry doors. From start to finish, from door selection to install.. the entire team was amazing to work with. Our order came in a bit early, was scheduled within days of getting the doors and installed to perfection. I have a feeling had there been any issues, the team would have bent over backwards to make things right… but it never came in to question. Thank you Jon, Lisa, Jim and team… what a well run, family owned business.. we’ll be back and happy to support a local company like yours!

Gravina's provides a high quality product. We have replaced four outside doors with three slider french doors and a traditional french door. We have also replaced five windows. Without a doubt, these changes have not only provided us with better insulation but have increased the value of our home. Beautiful. We are very happy.

My partner and i went to the Denver home show on Saturday as we are in the market for windows. We stopped by Gravina's booth in hopes to get a quote set up. The guy working there came across like we were inconveniencing him. When he finally decided to ask if we needed something, i said we're in the market for vinyl windows. He immediately quipped back that Gravina's doesn't do vinyl and he didn't even let me explain anything else. I feel like we were not given the opportunity to even shop Gravina's, and i can't help but wonder if it's because we are gay. We've since heard Gravina's commercial on line which states Gravina's does do vinyl. I do hope it was just a misunderstanding and not selective bigotry. Unfortunately we didn't get the gentleman's name at the home show. We did get a contract for new windows with another company.

What a great company! We purchased an entry door for our garage, the installer worked efficiently and went above and beyond our expectations. Our old door was hard to open and not square, Brian made sure the new one was perfect. The attention to detail is unmatched! We will definitely use Gravina’s Window Center for all our windows and doors.

ght $10k of Marvin Infinity Windows in 2010; came w/Limited Lifetime warranty. Now the Ultrex Fibreglass frames are fading and discoloring and the weatherstripping is shredding and failing. Gravinas won't honor the Warranty and is slow and hard to communicate with - they have told us that " upper management at Marvin will have to decide" what gets done and who will do the work. Gravinas is not an ethical, or responsible, company and Jim Gravina is a poor business owner/manager! I recommend that no-one does business with Gravina's - if you do you'll be sorry if you ever have a problem or need help. On the other hand Lifetime Windows and Siding sells Marvin Windows and stands behind their products and customers; a MUCH better choice for anyone looking for replacement windows.

We're thrilled with our Marvin Infinity windows and the entire Gravina's team. It's now been several months since we had them installed. We've noticed that they kept the house cooler during our ridiculously hot September weather and are keeping the house warmer now that we're moving into winter. The installation team was hard-working, efficient, highly professional and just really nice! No last-minute cost adjustments. Highly recommend.

Gravina's of Littleton replaced 10 windows (8 gliders and 2 stationary) in my house with Marvin Infinity windows. I am presently awaiting the finalization staining phase. I have generally been quite pleased with the products and services that were supplied. During the initial introduction and generally throughout the process, they have conducted themselves professionally and been very responsive to my questions and concerns offering fairly thorough responses. The windows and their installation look quite good to me. The foreman (Rich) was considerate and friendly and professional. The installation team provided drop clothes and plastic barriers to contain the work and cleaned up nicely after each days work. I am pleased with the overall experience.

Gravina's has been an absolute pleasure working with from the initial evaluation and meeting with Justin and John. To Lisa helping me find the ebony color that looks amazing on my house in the showroom. To the lead installer, Tom, once they were manufactured who did an excellent job with his installation team. Had one issue and it was resolved no problem. I was so impressed I have already ordered part 2 of the project! Plus as someone who works in a small family business the professionalism, kindness and feeling you were taken care of were all there! The same way I earn clients trust and why I love small business.

Additionally they use Marvin, high quality materials and Tom was an excellent installer. Have Justin and John out for an estimate!

Thank you!

Sincerely,
Brian
