Gravina's Window Center of Littleton

Gravina's Window Center of Littleton is seriously the best company we have EVER had work on our house. We got 3 bids, but the detail orientation and professionalism of Jon and Crissy Gravinas was hands down the best. They educated us about our replacement options, so we knew we got the best value for our budget. Our old windows were incredibly difficult to remove, and had to be cut into pieces and pried out in order to avoid damaging the metal siding, but they managed to avoid causing any damage, and then didn’t charge us extra for the difficulty, even though our install took more time and energy than an average job our size. The quality of the finished product also far surpassed the quality of other work that’s been done on our house. We went with relatively inexpensive windows due to our limited budget, but the high quality installation made the windows feel like higher end windows than they actually were. The installers also kept our house clean, carefully moved and put back the furniture, and left our house fully sealed up each night. They treated our house nicer than we do! If we ever need to purchase windows in the future at this or another home, I will only hire Gravina’s Window Center of Littleton.

We've used Gravina for the past few years. They installed replacement Marvin windows throughout our home and this past month they replaced our front door and sidelight. Each time the work was done beautifully and professionally. We would recommend using the Gravina company to anyone looking to purchase new windows or doors.

A+++ work and product. Installers, Mario and Rene were amazing. My windows look so great that my neighbors are commenting. We had our first freeze earlier this week, and my heat didn't turn on once, and it used to run all the time with my old drafty windows. The quality of the windows is top notch, and I find myself standing and looking at them with a big smile on my face. Highly recommend.

I contacted 3 Window Companies to replace 2 old large windows in my Living Room and Dining Room, plus needed a window removed and replaced with a French Double Door leading to my Patio. They came to my house, took measurements and gave me the best possible bid and better products than the others. The work was done within 2 weeks and I honestly can't believe how beautiful everything turned out. I will use them again when I need another door in my upstairs office -- leading to my new deck (yet to be built). Gravina's is one of the best companies in Littleton.

Salesperson provided relevant information to make a purchasing decision but was respectful of my time and not hard-sell. Installers were professional and efficient and finished the work within the promised time frame. Fine quality product.

We had five companies give us estimates to replace half the windows (15) and two sliding doors in our home. Gravina's provided a very competitive quote. Their installation crew (led by Tyler) was extremely professional and impressive. Any time we had a question, Tyler stopped what he was doing and provided a thorough explanation. He also kept on top of his crew and made sure they were working throughout the entire time they were in our home. As an engineer, I was very impressed with Tyler's attention to detail and the quality of his work. As I painted both the inside and outside of our new windows/doors, I got to see the quality of the installation crew's work. Overall, we were very impressed. We did have a problem with one of our screens on the sliding door and are waiting for Gravina's to respond to make repairs.

Gravina's is a wonderful company! They are top notch - everything was great through the whole process with phone calls, installation, clean up....We highly recommend using them - very professional and quality work!

I had my large sliding glass door and bedroom sliding window replaced. The sales process was 5 stars. The product quality is 5 stars. The installation was 5 stars. The improvement is 5 stars. I'm SO glad I went with Gravina's and Infinity by Marvin over the other company I received a quote from (even though Gravina's was more expensive). I've referred 2 of my neighbors to Gravina's. It's refreshing to do business with a local (CO), family-run company.

Hail damage to our house which included window replacement. I spoke to 6 different window contractors both commercial and independent contractors. Gravina's Window was our choice and was completely satisfied! They were not the cheapest nor the most expensive. Very professional from start to finish. We would recommend to everyone the product and quality worth every penny!

Our house was built in 1984. We were feeling drafts in the house and decided it was time to for new windows. Our search started by determining the best window for our home. We used the internet, neighbors and home shows to gather information. After narrowing the search, we interviewed and received quotes from several companies. All the companies were professional and provided fair quotes. In the end, we decided on Gravina's of Littleton because of the experience and confidence we felt with them. We feel the Marvin windows are the best on the market for our needs. The prices were more than fair and the entire process made us want to do business with them in the future. The entire process was completed professionally and on schedule. There are always a few stumbling blocks and those were handled immediately and fairly. The word professional to describe our experience is important but a better word to describe it would be family. We felt that all of the people involved became part of our family. We would welcome anyone of the people involved to stop at our house and chat anytime they felt so moved!

We could not be more pleased with the product quality and service by Gravina's!! Our product came in about 2 weeks ahead of schedule. The sales staff is not pushy and allows for the customer to decide without feeling rushed. Our windows are beautiful and we will use Gravina's again.

We had Gravina's finish a window project that Renewal By Anderson started a few years ago. We got tired of Anderson calling us all the time and sending "special prices" that did not turn out to be very special. The Gravina Marvin windows have a few features not offered on the Anderson windows. The installation crew did a great job and cleaned up completely when they were finished. The measurement and ordering went through without a hitch.
