After having experiencing contractors in the past that had left us feeling frustrated, disappointed…read moreand 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 Gravina 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! ~ Kevin & Jeri-Lynn ~

I requested a formal contract from Gravina's for a full-frame window and sliding door replacement…read moreproject. The sales rep, Mark, provided a detailed itemized quote and answered initial spec questions promptly. When I mentioned that another vendor's quote was significantly lower and asked for a formal contract to compare, the rep declined to finalize the contract or calculate exact measurements unless I first shared the competing company's proposal. I explained that I don't share competitor quotes with any vendor, as a matter of fairness, and asked again for Gravina's own formal contract with their best price. I followed up twice over the following week, including a specific deadline for the contract, and received no contract or further response from the rep. I then forwarded the full email exchange directly to the sales director so the company could review it and respond if they chose to. That email also went unanswered. The initial consultation and product information were professional. However, despite being a ready buyer and giving the company multiple opportunities to follow through, I was unable to get a final contract at any level, and ultimately went with another company that provided a complete, firm proposal without conditions.

New windows are a significant financial investment and Paramount was easily the best decision for our investment!
