JDI gave me outstanding options for replacing my windows at a great price. I did not get their premium windows. I just went for their second tier basic windows. The entire process from the initial consultation, measuring and ordering windows custom made for my home and installation was roughly 6 weeks. The owner who conducted the initial consultation, scheduler, crew foreman, and crew members were fast, efficient, cleaned up the demolition of the original windows beautifully and were very friendly. Some were even born and raised in the same neighborhood as me. I can't believe how nice these windows are, how they have improved the beauty, air tightness of my home for drafts, temperature changes and for outside ambient noise reduction. Their ease of use is outstanding. I can't say enough superlatives about JDI. I would give them 10 stars if I could. THANK YOU!!!!!

They did a wonderful job the windows look and operate per and we couldnt be happier. Rare these days when something like this actually goes as well as it possibly could have.

After getting four quotes, I came to realize that each company pretty much has one type of siding they recommend and install. For one company we interviewed it was LP (engineered wood), for two companies it was Hardie (fiber cement), and for the last company, Superior Industries, it was a material we hadn't heard of before: Gentek ALIGN Composite Cladding (aka Alside ASCEND Composite Cladding). I was initially skeptical because I hadn't come across it in my research. How good could it be? Turns out, amazing. Really glad I called Mike to come take a look, as otherwise we would have ended up spending a lot more to get a not-quite-as-good product. Superior Industries replaced all of our siding, soffits, and facia, and aluminum-wrapped all new trim boards for us. They did precise, high-quality work and it really shows. Communication was good throughout and the guys who did the work were friendly and competent. Mike only has a couple teams, so these guys have been with him for many years and really know their stuff. They listened to everything I had to say, they consulted me when there were any decisions to be made, and they answered all my questions. Everything looks great and we are very pleased.

Inferior Product Installed…read more I needed new windows for a remodel I am doing in my daughter's condo. I contacted Superior Industries for one of three quotes I received. Mike came to respresent Superior. Mike and I discussed in detail about the color of the windows. I probably told Mike at least a dozen times "I need brown windows," "The windows must be brown." Not once did Mike speak up to tell me the windows he had in mind would be white inside. I fully expected the windows to be brown inside and out. Mike emailed me a work order where he added "white inside" to the description of the windows. I didn't notice this detail in the work order, but at the same time, I did not approve or sign-off on this work order. I approved the install solely on the promise of brown windows at a quoted price of $11,262. What business person would believe that simply sending out a work order, with no sign-off by the customer, indicates acceptance by the customer? The windows Superior installed are much cheaper windows than all-brown windows would have been. I accepted their quote believing I would get all brown windows. Quotes from the other vendors indicate brown and white windows sell for three to four thousand dollars less than all brown windows. I overpaid by three to four thousand dollars! I entered into agreement with Superior in good faith. I did not get respect or good faith in return. Instead, I got an inferior product where a much better product was promised. I will never do business with this company again. Update to Mike's response: What contract? A contract is a document where both parties sign-off agreeing to the terms of the contract. My signature does not appear on any such document. The email Mike references approves only the quote based on a promise of seven brown windows. I never approved the work order via email. I challenge Mike to post here any proof that I signed-off or otherwise approved the terms of his "work order."

Don't hesitate, call now!  Over the past seven years we replaced all of our windows.  We did this…read morein thirds:  The first and second time we went through Discount Windows and Siding.  This is when they were discount windows.  Since then their prices tripled which prompted us to shop around, obtaining estimates from four more window companies.  Enter Jay from 303 Windows.  What a breath of fresh air!  From the first call Jay was prompt, professional, courteous, VERY KNOWLEDGEABLE, reasonable, observant, and keen on details (he was the only window man in seven years who pointed out that the grids in our windows did not match the others).  He's a straight shooter who won't steer you in the wrong direction.  Any follow-up questions or concerns are immediately addressed and resolved.  Others may have had lower bids, but Jay's integrity and confidence won the day.    From start to finish, the measuring, estimating, ordering and installation went without one hiccup.  I'd like to talk more about the people (very good communicators and listeners) before I describe the windows.  Rick came out to do the measuring.  He was fast and efficient.  Five guys showed up on installation day:  John, the front man who had the sweetest disposition, explained what they were going to do and how they would do it.  Dan, the most energetic and spry person I've met to date, elected to be the one to install the window over my jetted tub because he was the lightest of the men and wanted to place the least amount of pressure standing on it.  Let me clarify that most of the work was done from the outside on all windows.  Upon meeting Vincent he quipped, "Nice to meet you".  I can't tell you the last time a young man has said that to me.  Two other men showed up as I was leaving for work do I did not get their names.  These five professional, hardworking and very competent men installed 9 windows in 4 hours.  As with any project, touch-ups were needed.  Both John and Dan asked me for my touch-up paint so they could leave my walls as they found them.  I was totally impressed with their caulk lines by the way.   The windows:  We hesitated 2 weeks putting our blinds back up because the windows are so darn pretty to look at.  Functional?  Hell yes and way better than the Discount Windows we currently have and those we've seen from other companies.  303 Windows have more sophisticated features such as an aluminum bar running the length of the window to remove the screen (instead of cheap plastic tabs that break), clean lines, curved locks that your fingers can easily manipulate, and an overall design that makes the windows look elegant.  They are both lightweight and durable, open and close without throwing your back out, secure, and help reduce noise.  In addition, all parts can be replaced such as latches, locks and security features vs replacing the entire window.   Since starting this journey seven years ago, we've had a great deal of estimates and salesmen at our house including Andersen, Champion, Home Depot, Lowes, Southwest, Affordable, and Gravina's along with other companies and contractors we have long since forgotten.  Oh the stories we could tell!  Save yourself the time and frustration.  Call 303 Windows now!  I wish we would have seven years ago!

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!

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 assume the ball was dropped somewhere in the process. I want to cancel the order and forget it. I chose this company based on a personal recommendation.

We paid extra for tiles that had a 15 year warranty. As soon as they finished the job I noticed a leak in roof so I called Adam the project manager. He came over did something and left. The roof was still leaking came back again put some tar on it left again, still leaking, he came back a third time and managed to fix it. Within a year I noticed the tiles were coming up on one corner. By the third year I started having roofing companies ask me if I needed my roof repaired as lots of tiles where coming up. I called johnson and Adam came back over and said he would see what he could do to have it repaired and would get back to us. He never called back, I called the company to complain and have someone else look at it but they sent Adam back over. He told us to put in a warranty claim on the tiles as he thought it was the tiles, but it is not. As you can see from the attached pictures, it is the workmanship of the company. The tiles are supposed to last for 15 years minimum. This company will only guarantee the work for two years. It has been five years and one month and the roofing tiles are coming up everywhere and i will need a new roof.
