The entire process, from proposal to completion, was a breeze. My home looks beautiful, and I am secure in knowing that the new siding installed by Bellwether is superior to the one it replaces.

Customer Service is Unbelievable. Let’s just say my job had challenges and Paul, Cole, and Karen didn’t give up until it was all done to my satisfaction. I just noticed, somehow one side of one window didn’t get caulked, I shared a picture with Cole (over a year after the initial completion) and he came out immediately and addressed the problem!Over the top customer service is something most companies have forgot, but bellwether knows how to treat its customers!I will plan to use bellwether again in the future, without any hesitation!Thanks Again.Mitch G.

Bellwether did a great job of replacing the siding on our home with pre-primed Hardie board in Castle Pines. The siding looks perfect and the detailing was done with precision. We couldn’t have been happier with the responsiveness of the company to any questions or concerns we might have and the crew worked well to complete the project in a timely fashion. It was a pleasure to work with the administrative staff, too. There was always a friendly and helpful voice on the other side of the line rather than a voice messaging or menu to scroll through . We highly recommend this family owned company to anyone looking for a siding replacement.

Bellwether did a great job putting James Hardie siding on my cabin near Black Hawk. The crew worked quickly and took care of any issues. There were some issues with material delivery, but the PM took care of them and made sure a solution was figured out. Great work! I’m glad I chose to work with them.

We hired Bellwether to replace some old pine wood siding. They did an excellent job. Lee and Julio stood out as 2 employees that went above and beyond. They were very professional and a pleasure to work with.

Cole the project manager kept everything running smooth and kept me updated on the progress of the project.

I would highly recommend Bellwether.If I could give 10 Stars I woud!!!

After going through the process of vetting several companies and receiving quotes for windows and siding, we decided to move forward with Bellwether. As you may have already figured out (if you’re reading this you’re likely shopping for a company), this process is not always the most pleasant as the companies vary greatly with the products they prefer, the prices can be drastically different even for the same products, and the overall feel of the representative that you’re working with.To begin with, getting an appointment with Bellwether was a breeze and speaking with them from the get go felt very professional and reassuring. I met with David from their sales team, and he got right to working with me to give me several iterations of what I wanted done, mostly based on different window choices. My one big ask of all the companies was to install new construction windows, rather than replacement type, since the siding would be coming off anyway. Much to my surprise Bellwether was one of maybe two companies that did not have an issue with this! Pricing was very competitive, and I really appreciated that they broke down all the costs in the quote, line by line. Whereas all the other companies gave you one number, not showing what cost what, Bellwether showed you all the minute details! Loved this, and made adjusting the work easier to meet budgets. Thanks, Dave.Moving onto the work itself, I give much praise to Cole, Lee, Luis and his crew. Luis and his team did an amazing job with demolition, and installing the new construction windows, siding, and all the soffits and fascia boards. Their eye for details is the best; the caulking by the lady is some of the best I’ve ever seen and was highly admired by the neighbors! They showed up on time every morning and worked hard all day. The house wrap, siding, trim, etc. look amazing and the house already feels more efficient inside. The Pella windows are a huge change from the original 40yr windows and Bellwether was one of two that agreed to install them.There were a couple of small hiccups that weren’t the fault of Bellwether; the Pella rep mis-measured one of the windows so we had to wait on the replacement. However, they installed the too small window temporarily so that we had a window, and came back to finish the job once the window came in. Also had a mishap with the gutters but Tanisha was wonderful about it and fixed it right away.Overall I am extremely pleased with how everything came out. It was a big job, but Bellwether came through and did a wonderful job with it. I am highly recommending them to my neighbors who are looking to have similar work done in the near future, and will surely use them again should the need ariseThank you to everyone at Bellwether.

Great experience with Bellweather Windows and Siding. From start to finish everyone I worked with was super! I had James Hardie siding and 4 Pella replacement windows installed. Seth, the salesperson was friendly, informative and clearly explained the process. Cole, the project manager kept the operation running smoothly and kept me in the loop with the progress of the job. Julio, the head of the installation crew was incredibly diligent in making sure they all got the job done efficiently each day. Everyone was quick to respond with any questions I had throughout the installation. Highly recommend this company! Thrilled with the final outcome.

Though the job started a bit bumpy with the foreman being changed out right before the job, Luis and especially Carlos took the reins and did an amazing transformation on our house. Beginning with David who designed a very complex siding facade, then it was well translated off the paper into reality. We were so impressed with and grateful for the hardworking Belwether employees who gave their utmost to get things right as well as their care and respect for our home. Thank you.

I’ve been thrilled with the service I’ve received from Bellwether. They did a beautiful job on my siding a couple years ago, and I’ve just now worked with them to replace my windows. Everyone involved with the company has been great to work with – polite, professional and thorough. One of the things that stood out to me is that I never had to remind anyone what color trim I had when I scheduled my window replacement, they knew what I had had done previously and ordered accordingly. They’re very well organized and are good at staying in contact about the current state of projects.

Had a fantastic experience with the whole team at Bellwether to reside our 1970s home. They were not the only quote we received, not the lowest bid either, and wow are we glad we went with them. From the first consult with Seth to working directly with the owners, our family is satisfied with the final look and follow up.The team worked fast even with construction happening on our street the first morning. They have been ultra responsive and accommodating for all our nitpicky details.Thank you Bellwether for making the experience painless and beautiful!

Cash Stricker was great and caught a couple of punchout items we hadn’t noticed! It’s stressful living in a construction zone for a week but the end result looks so good. Looking forward to comparing heating bills from past years now that our home has been ungraded to have OSB sheathing and Hardiewrap.

Bellweather Windows, Siding and Doors team updated our 1975 windows & siding and did a awesome job! The entire team from up front to the execution has been an incredible group to work with and was amazed by the speed of execution and quality of work during install. Will be definitely recommending them to friends, family and neighbors.

We had Bellwether replace our siding and it was a great experience! The whole process was quick and went smoothly. The office was very easy to communicate with and talked us through everything and the contractors were excellent. We literally have no complaints and are very happy with the end result!

Bellwether exceeded my expectations! From my first contact with salesman Steve Dennis and then Project Manager Paul Dickens, both listened and answered my questions and assured me the project would be done to my expectations. Well the day of the job 15 men showed up, headed by lead man Angel. His crew was so well orchestrated, they stripped the whole house of all cedar siding, wrapped and started siding the first day. The attention to detail was amazing and the house was fully sided with Hardie Board in 2 1/2 days. What a great job! I’m still walking around in amazement.

The rep who came to the house was very thorough and professional. The quote was quite detailed and made me feel everything was covered. I would have happily gone with them, but their price was much higher than the others. I just couldn’t do it.

When I purchased my home in 2021, it was dressed in the original cedar siding — and it was forty years old. When animals started chewing through my walls I knew it was time to replace it. As a single woman and first time homeowner, the estimates I was given were often marked up significantly and I felt confused and nervous about the entire process. I had spoken with Steve the year prior when I was under contract, and his warm and honest demeanor was immediately disarming. When I hit him up a year later, he not only was willing to stop by and look at things again, but spent a lot of time explaning every detail to me in a way that didn’t feel patronizing at all.Steve worked to give me the best possible price on my renovation, and he helped me decide on the financing that was most honoring for me. From the moment the project began, Paul was kind, responsive, and beyond helpful when any issues came up. Their team was fast, efficient, and respectful–and they did an amazing job. It has been fourteen months since my home got a facelift, and in that time we’ve had three major hailstorms and countless snowstorms and this siding doesn’t even have so much as a chip on it. I can not recommend Bellweather enough.

Steve Dennis and his team at Bellwether did an amazing job replacing the siding on my entire house. They were fast, efficient and thorough. I highly recommend Bellwether to anyone needing siding work.

We installed a new Sierra Pacific door and 3 Pelle windows in our Lennar house in the northend area. The process took around 3 months and we’re super pleased with the quality and care towards making our vision into a beautiful reality. The design process was super smooth and gave us a lot of ideas to work with while considering the structural integrity and resell value. The actual work days where the house was in a mess was less than 6 days, but scheduling and holidays was a factor in making sure everything was fully addressed. We’re 100% working with Josh and Tanisha (and their great contractors) again on future projects. I think their team enjoys unique projects like cutting wider openings for walls and solving harder problems than just replacing siding and installing windows. Extremely skilled professionals.

Beautiful work! Great Service! I even had one issue with the paint and they came right out to my house to fix it in the same week! I Love how the new siding looks and Bellwether was great to work with.

I had a great experience with Bellwether for replacing all the siding on my home in November 2023. It was a major project, that came together beautifully! I’m so pleased with the final product, the excellent service I received, the attention to detail and getting the project done right on schedule. I especially appreciated Paul as my project manager-he was SO responsive anytime I texted him a question. There were a couple of minor hiccups in the process, but Paul addressed them very quickly, and to my complete satisfaction. I would highly recommend this company for replacing siding.

We were extremely pleased with our experience with Bellwether! From our salesman, Steve Dennis, to the front office personnel,Paul,Tanisha,and Karen, to the installers. They were all exceptionally knowledgeable, friendly and professional. They assisted with our dealings with insurance, project timing, and completion steps. Everyone was friendly and willing to work around our needs and schedule. As the City inspector left, he said “They did a great job for you.” We can’t agree more! Thanks, Bellwether for what you have done for us.Richard and Lynne JonesAurora, Colorado

Great business to work with

Had all of our siding replaced by Bellwether with James Hardie siding. They finished off the job by sealing and painting all eaves and trim work not replaced. Final product looks great. They had a few items to come back and complete and did so quickly and to our satisfaction. Great pricing, great communication. Would have given 5 starts but the installation crew did not do a good job of cleaning up everyday after they finished work. There was a dumpster literally in the driveway but our yard surrounding the house was littered with food and drink containers. That stated, Happy customers and would recommend.

I had a siding project completed over a year ago and noticed some minor issues. I contacted Bellwether about it and they sent someone out when it was convenient for me. They treated me as well doing follow-up work as they did when they were trying to win my business and during the actual project. You can’t go wrong with this company and it’s people.

We live in Steamboat. We tried and tried to find a local contractor to re-insulate, instal new windows, and re-side our 120 year old mountain home. Couldn’t get anyone locally to even return a phone call. My wife reached out to Bellwether and three days later we were meeting with their rep and planning our project. Within a month our remodel began. We were amazed by how quick, professional, and skilled the crews were. They tore off the old siding and insulation and removed the old windows. Four weeks later our home was complete; new windows, insulation and siding. And we couldn’t happier. What was a 120 year old cold, drafty house is now a tight, beautiful comfortable home. Bellwether did an amazing job of upgrading our home for the extreme demands of mountain living!! Thank you Eric (windows) Alex (siding) and Alex (painting) for your professionalism, skill and outright pleasantness. I would recommend Bellwether to anyone in a Colorado mountain community for their quality work.

Bellwether was phenomenal. Cash came to the house in May after a large hail storm that damaged the vinyl on multiple sides. He spent over an hour talking with me, answering questions, and reviewing options. I said I didn’t want a big beige house, and wanted to find a new, modernized aesthetic. He took my elementary ideas and ran with them, giving me a bid and first rendering in only a few days. We could tell from the visual rendering that it would be a stand-out house! Then it was about the process of transformation. The crews worked diligently even in 90 degree weather, were respectful, and cleaned each day. Their work was precise and exhibited true craftsmanship. Everyone we worked with cared about what their efforts were bringing in total. The text thread for the PM and the crew lead were always responded to. Even in the walk-throughs, they listened to any concerns I had and I could tell the whole team was pleased with the final product. The house is beautiful and with the upgrade to James Hardie, I think it will remain as such for many, many years. My neighbors loved watching the process with me.

Bellweather was great to work with from sales team, site manager and installation crew. They showed up on time and did an excellent job. The crew was very nice and respectful and the workmanship is outstanding. When the project was completed, the crew walked the site with us to make sure everything was satisfactory, then, the site manager walked the project with us and went over every inch of caulk, piece of flashing and board. It was installed by James Hardy Board trained people who knew what they were doing. We highly recommend this product installed by this company.

We could not have had a better experience with Bellwether. They were professional, on time, delivered a beautiful quality product, and met all of our expectations. The ease of their process was a breath of fresh air. We completely re-sided the outside of our house from old mountain cedar siding to gorgeous James Hardie board and batten fiber-cement siding. They also handled replacement of all of the 40 year old windows in the house. It was a big job handled like clock-work. We had nothing but confidence in them the entire way through the project.We would use them again in a heart-beat and have referred other people to them who have already had their homes done. Save yourself some time, energy, worry, and heartache, and work with Bellwether.

Bellwether was a delight to work with starting with Cash Stricker. One of the original owners, actually has installed the Hardie Board Product. He could answer all my questions and provided an accurate, easy to understand estimate. The installers, Mario and Heberto worked with care and patience like they were working on their own home. All building codes for building wrap, rafter framing and flashing designs were followed ( I asked lots of questions during the renovation). The Painters and Gutter Crews were equally as Caring and Professional. All of the office staff I worked were equally friendly and caring. Bellwether was like working with family.All of the materials were delivered on time and as scheduled. The RedBox trash hopper with attached outhouses was plenty big enough for the old siding, fascia and soffit boards. A tarp was used to catch all of the material as it was being removed from the house and then moved to the trash hopper. The site was cleaned, swept and picked-up every day.The results of the Hardie Board installation were stunning. The Rich Expresso siding with Arctic White trim makes my house built in 1967, look brand new and totally transformed. Several neighbors out for their daily walks have stopped and stated how nice it looks. A new project is being started down the street based on the great looks of our house.I could not be happier about my Hardie Board renovation and the Bellwether Company. I would recommend Bellwether without question. I was so proud of the work, that I welcomed Frank the photographer here today for a photo and video shoot. I guess that says it all.

Project was installation of Hardie Board on cabin and detached garage near Cripple Creek. Hand holding through process of selecting colors was beyond expectations. Communications before, during and after were excellent. Neighbors are impressed. Highly recommend Bellwether.

Overall, Bellwether is priced in the middle of the pack, they have quality workmanship and are incredibly fast. My siding was removed and replaced and painted in four days (compared to a neighbor’s siding, where the other company took several weeks). It looks great! I had some issues with disorganized or missed communication, but after the project the owner sat down with me to discuss lessons learned so he could take that feedback forward. To me, that speaks to the companies dedication to quality.

Our Team

At the core of Bellwether is a firm dedication to customer service and excellence in everything we do, complemented by an eagerness to learn and a love for the work.
