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!

Selecting Paramount Siding & Windows for our window project was the absolute best decision!…read more *Sue in the office is super sweet, professional and responsive. *Scott came to our home for the sales pitch but is wasn't salesy at all! We had a great conversation, we walked through the house, what we were looking to do and he made recommendations that fit our needs. He was highly responsive and submitted a proposal quickly. Best price and value from everyone we talked to! *Jon came out to do measurements and take video for the install team. Another great experience! He was thorough, asked additional questions, set ther install team up for success and set our expectations. *Install was a breeze! We had an amazing team who came in and made the magic happen over 3 days. Day one was old windows out, new windows in. They were methodical, detail oriented and the moved so seamlessly! Day two was outside details and day three was inside details. The disruption was much less than we imagined. New windows are a significant financial investment and Paramount was easily the best decision for our investment!

I've had WestPro come quote the same job twice, once in 2023 and once in 2025. It was two very…read moredifferent experiences to the point of being hard to believe it's the same company. The job is for removal and replacement of soffits, fascia, gutters and downspouts on a 1-story ranch with 200 linear feet of gutters. In 2023 a woman came out, did the walk through and then sent me a quote with details about the materials, a cost breakdown for each part of the project - quantity and cost for removal of gutters, removal of downspouts, installation of gutters, installation of downspouts. It was very professional (I work with contractors and job bids for a living) and provided all the necessary details of the cost. In 2023 they refused to address the soffit and fascia so I declined to move forward with them. In 2025 a man came out, did the walk through and then insisted on setting up a follow up appointment to walk through the project quote. I did not receive the info packet ahead of time and was disappointed by what I received - a detailed project description for siding work (presumably for the soffits and fascia but the material was specific to siding installation which isn't relevant to either of those locations) with no scoped quote for any aspect of the project. There were no details of the materials to be used or breakdown of the cost specifics. The dollar amounts were hand written into a spec sheet of "good / better / best" (photo attached because I don't even know what to call it, it's definitely not a job quote). I understand that materials costs have changed significantly and the job might cost more today than two years ago, but if you're going to waste my time with a second meeting to quote the job, actually quote the job. So your experience with WestPro may entirely depend upon the person you randomly end up with as your project coordinator. Homeowner be wary. I'll update this review when I've heard back with legit quotes and decisions on a path forward. For now it's a very unimpressed meh.

We hired Five Seasons last year to replace most of our windows for our home. Some of our windows…read morewere fairly large, and we also had two sliding glass doors replaced. So, this was a big project and we were very nervous as it was our first time doing this. From the start, we were impressed by the sales process. They went over our preferences and needs multiple times, made many iterations, and finally, we settled on the windows to replace, the style, the amount of sun filtering, etc. We chose Marvin windows as the window manufacturer, and Five Seasons then handled the installation. Now that it's been a year, we can say that Five Seasons supports their work really well. We had some problems with the hardware side of some of our Marvin windows and doors. It wasn't anything major, but things that should have been working properly. Dylan and Makayla provided exceptional support and actually rebuilt our sliding glass door locks for us, and since they did their work, the door locks have been working perfectly. The window installers, under Mike, did a great job installing windows that were large and in difficult locations. We have now had a year to see how they have held up to wind, rain, and cold weather and they are doing great. We are glad we went with Five Seasons. They were reasonably priced, installed the windows when scheduled, and have been providing excellent support.

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 would love to be able to give zero stars…read more I will not be recomending Gravinas to anyone I know. We needed to get a quote for a couple of windows that needed to be replaced due to being damaged, and covered under insuance. We had a consultation at the house and were told we would recieve a quote in a couple days. We did not recieve a quote, which lead to us calling and leaving 5 messages with Chrissy. On the 6th call we finally got a hold of her, to then be told that the windows we were needing replaced would not be a match for insurance (which was never conveyed at the walkthrough of the house) and that it would be more expensive than what we had. I then asked if we could still get a breakdown of the quote to understand the differences. Chrissy proceeded to list numbers for a full install over the phone of an all inclusive package. When I asked for a breakdown of the pricing to fully grasp the whole package, she questioned whether we would really want to spend $3,500 per window and implied we could not afford it. Needless to say, it felt incredibly rude and condesending and we will not be giving Gravinas any business.
