Rarely we come across an exceptional businesses that actually provide what they sell. Many are fancy on words, promises, but few actually deliver. Bellwether Homes did an outstanding job installing James Hardie siding on my home. Their extensive experience working with the Green Valley North HOA made the entire process smooth and reassuring, and their attention to detail was evident in the final result. As a first-time homebuyer, I had many questions throughout the project, and the Bellwether team was incredibly patient, helpful, and professional every step of the way. They took the time to explain the process, address my concerns, and make sure I felt comfortable with each decision. I truly appreciate all the hard work from everyone at Bellwether Homes, from the office staff to the build team. The employees who completed the work were skilled, respectful, and clearly took pride in what they do. Everything looks fantastic, and I couldn’t be happier with the finished product. I highly recommend Bellwether Homes to anyone considering a home improvement project. The proof is in the before pictures taken after the hail storm in NE Denver and the after pictures I provided, they say it all. Thank you Bellwether Homes for my James Hardie siding!

If you’re looking for window and door replacement, I can’t recommend Bellwether enough. From start to finish, the entire process was smooth and straightforward. Their pricing was competitive and reasonable, and the installation crew was prompt, respectful, and completed the job in a very reasonable timeframe without cutting any corners. The final result looks fantastic—so much so that we immediately recommended Bellwether to our neighbors next door. Great team and top-notch work!

Could not recommend Bellwether enough! My home is currently for sale, and the James Hardie siding update they completed has been a total game changer. Not only does it look fantastic, but it has significantly improved the overall curb appeal and value of my home. From start to finish, every person I worked with was responsive, professional, and genuinely helpful. I especially appreciated the free consultation to discuss options, the 3D visualization tool that allowed me to see different siding styles and colors on my actual home, and their willingness to accommodate my accelerated timeline. The entire process was smooth, well-organized, and exceeded my expectations. The first photo shows the siding before the project, and the second shows the finished result. The quality of the James Hardie product combined with Bellwether's craftsmanship made a huge difference in the final result. I couldn't be happier with how it turned out and would absolutely recommend Bellwether to anyone considering a siding project.

I had the opportunity to work with Bellwether in the Summer & Fall of 2025. (It is my very own fault that my review is nearly five hundred twenty five thousand six hundred minutes late in posting!) Nick rolled up to my house on a hot June day for our initial meeting. Prior to this meeting, I had met with two other companies (who will remain nameless) who had presented me with good, better, best options for a siding project so I had some general figures in mind. I was not entirely sure this was a project I could even take on, if I was being honest, and I told Nick that, and he held space for it. One thing that is really notable about Bellwether is that they only offer the best option, and because it is the best option, it's a product that everyone who works for them backs and supports and THAT is something I get down with. Anyway, Nick and I sat in that hot summer sun for nearly five hours (yes, you read that correctly) sometimes in silence, analyzing every option on this green Earth. You see, I have a very long house and I wasn't yet sure if I wanted to replace the siding on the whole thing or maybe do half of it. Did I need new windows? I knew at least three...but then are all the rest going to look old and crusty next to the new ones? Probably. How about new soffit from where the squirrels chewed through? There was a lot to discuss and Nick was there through it all. At one point we even took a couple calls with Josh & Tanisha who were available to answer questions on the spot as well. At no point did I feel pressure in this process, but it is important to me to convey how much belief this company (and now me) have in this product and the craftpeopleship behind it. Moving into production, I was deeply appreciative of how flexible the team was with working around both my work schedule and the already existing schedule of the tenants in my rental, which is the south end of my home. I was trying to accomplish this project while not disturbing or uprooting them, which was an added challenge that Bellwether had to navigate throughout the process. Dennis and Dylan were communicative with the ordering, delivery, and installation process, as well as when issues arose (as they do in any construction process) they were quick to problem-solve with me on the phone when I couldn't physically be on site. The James Hardie siding is such a CLEAN look. Pair that with the framing of the windows and edges of your house and all that matching the soffit, facia, and gutters--I mean, chef's kiss! The caulking also all matches the color of what is being caulked. It's the details for me! I loved how the entire crew wore Bellwether swag while working each and every day! The team was very thorough with clean up each day of construction as well. My project involved 17 windows total, five of which weren't included in the initial order and delivery, and Bellwether was quick to remedy this and took accountability for the misstep. Due to my next tenant, those windows had a later install date, and the crew came to replace all the framing again after the new windows were put in, after having already done this once. I had expected the previous new framing to be reused and was glad to see and know it was all replaced and brand new! Bellwether's honesty, reliability, and integrity throughout my experience is what makes them stand out in this industry and why I would recommend them to anyone seeking the same service. I want to also acknowledge Luis who put many final touches on my windows in the Fall, which really made them pop. His dedication to making it right and finishing the job out is much appreciated! And a S/O to Mason who swung by to check out the work, get to know me, and spread some positive Bellwether vibes. So many neighbors have told me they have NEVER noticed my very cute 91-year-old house before this facelift, but look-at-her-now-look-at-her-now-she's-gettin'-paper(cuter). Thanks s'much Bellwether!! Up next--doors! I need em, you got em! I'll hit ya up!

The project manager Ezekiel was great and deserves five stars for his attention and dedication to the project and getting it completed to the customers satisfaction. Unfortunately he inherited a window and Siding replacement Project that was initially delayed apparently due to staffing Issues. The home office Did not communicate well with me after I signed the contract and made down payment.They Did not apply for a building permit prior to sending a crew. This caused a delay in project start. Apparently the Person they sent initially did not do accurate field measurements, therefore materials were delivered to the site in the wrong quantities and sizes delaying the project again. Some materials were delivered damaged causing additional delays. The Initial wainscoting Installation was installed with corners and damaged / scratched materials and needed replacement by a professional sheet metal crew. This caused another delay. The project took six months from the time I made down payment and final punch list completion. Initially, I was told the Project Would take 8 to 10 days from the time it started.Ultimately, the project looks great. I highly recommend the project manager bur was not impressed by the rest of the staffing at Bellweather.
