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. And to top it off their pricing was more fair than anyone we got quotes from. I would highly recommend them!

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!!!!!

We were looking to replace our 28-year-old, builder-grade siding that was showing signs of water…read moreretention. 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."

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.
