Most of those I called did not seem to interested in such a small project. However, when I called Window Doctor of Colorado, Chris was more than willing to help out! He cut me the piece I needed in a couple of days. When I went to pick it up, he told me he was happy to help and there would be no charge! That was not expected. There are very few companies that would demonstrate that kind of service from start to finish. An amazing company that is concerned with your needs!

Mike and the team at Superior were really great to work with. We received quotes from 2 other…read morecompanies in the Denver area, but when Mike visited I knew they were the right fit for us. He felt both genuine and knowledgeable, and that proved out over the quoting process and engagement. While the wait for our windows took a little longer than we had hoped, Mike was really responsive and when the window did arrive installation was scheduled immediately. I'd wholeheartedly work with them again and recommend them to others!

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.

I needed the front side of my home resided and needed two new windows installed. They were able to come out for an assessment relatively quickly and from the assessment time to a finished product was about six weeks. For the duration of the project, I was able to stay in constant communication and was updated regularly. I appreciate that the owner of the business is actively engaged in all projects as well. While any house project is going to hit your wallet a bit, 1st Choice is definitely worth the cost and has competitive pricing to other companies. I highly recommend 1st Choice Windows And Siding!

I got quotes from ten well known, well reviewed window companies in the Littleton area and Thibault was by far the most responsive, no-nonsense and respectful of my time professional out there. As a female homeowner, I really appreciate not having to sit through a condescending two hour high pressure sales pitch. I know what I want, please just give me a fair price. Thibault did just that, while being extremely knowledgeable, and the pricing was fantastic as well. I am affiliated in no way with this company and truly blown away by their customer service. Highly recommend!

When we were referred to Windows America by a friend, we also needed 2 other quotes for cost comparison. Not only were these Windows America the best price, they looked after us in ALL aspects of the installation process. We have seen a significant reduction in our electric and gas bills! Our home now has a BETTER UV protection in the windows for protecting our cabinets, floors and wooden furniture. They also have the bottom up/top down locking windows (for a comfortable breeze), which was an up charge at the other two companies that had quoted on the replacement windows! Matt and his team were outstanding to work with! We also loved that they are locally owned, a family run business and they employed veterans throughout their various levels of employ! They TRULY wanted us happy and bent over backwards to help us with this HUGE project! In any big projects, there can be a snag or two...(the joy of construction work--haha!). But, the snags we'd had were small and were handled professionally, promptly and all parties were happy with the results!
