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.

Excellent products, professional and knowledgeable staff, competent crews, fair pricing.

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.

Sara Gonzales

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

Ed Hester

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.

Bellwether and crew were superb. Materials and support arrived as scheduled. Project managers were checking in regularly. Adjustments were seamless. The whole project proceeded from start to finish as promised.

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.

Rich Fisher

Bellwether is a reputable and responsive company with highly professional construction experts who will expertly advise you on your project. I highly recommend Bellwether for your home project.

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.

I did have some challenges with my initial project, but Paul and the team addressed all of the issues and fixed things perfectly!

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.

Kelly Toney

1689890552

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.

Katie Wood

1687286432

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.

Lauran

Bellwether replaced our 100 year old shingle siding with James Hardy, paying great attention to the detail of our home. From our sales person, Tom, to our installer, Alejandro, the communication and professionalism was top notch. Install went well even with weather delays. Painting was the final phase of the project and communication broke down a bit as Bellwether contracts out for their paint jobs. However, when mistakes were made, Bellwether was quick to address and fix them.If you have a siding job and want it done to the highest level, hire this company!

Colorado Siding Repair replaced our old siding with JamesHardie sidings/trim. Great experience working with them. Excellent job overall. We are very pleased that we chose them over three or four other bids. The results were excellent and would not hesitate to use them for any other services they provide. They also took care of some minor issues we brought up once we were there. I would highly recommend if you want new siding.

I contracted with Bellwether to install new siding on my home. Every employee that I spoke with was helpful and professional, but especially the crew that installed the new siding. They transformed the exterior of my home that now has some curb appeal. My neighbors all commented on how much they liked the new look. Peggy C.

I have nothing but positive things to say about our partnership with Cash, Paul, and the entire Bellwether/Colorado Siding Repair team. When we began the vendor evaluation process for the complete residing of our 1950’s MCM home, we had a very particular idea of what we were hoping to achieve as an outcome.After sitting on the receiving end of multi-hour, in home sales presentations, including hard line negotiating and closing tactics from from 4-5 other vendors, we had all but given up on finding a contractor to partner with.Cash arrived at our first consultation and, (gasp) asked questions and listened to what we had in mind, evaluated our budget, and presented creative solutions from their supplier library that would get us as close to our ideal while respecting our overall budget. It was a breath of fresh air and welcome respite from the other vendors we had been in discussions with and it was clear that this was the team for us.From the contracting window to the install date, the team is prompt, professional, and communicates clearly throughout the process and we felt well informed of what to expect and what they were expecting of us.Upon the handoff from Cash on the sales side to Paul on the installation side, we couldn’t have been more pleased. With respect to our borderline obsessive compulsion with what we wanted, Paul was quick to acknowledge fault, take ownership, and have his detail team quickly address the areas of concern.Finally, post install the team has made us feel well respected and valued. We had two minor workmanship requests that popped up 8 months after install and the team dispatched another repair crew, without question to address the concern.Again, I can’t say enough positive things about working with this team and would whole-heartedly recommend them to any friend, family member, or even stranger evaluating a residing of their home.

Colorado Siding Repair, now Bellwether replaced our old siding with Hardie Plank and also added a couple of new windows we wanted, where many others were not able to. Excellent job overall. Was all done virtually as well before our moving in showing us detailed pictures of the work they did and they also took care of some minor issues we brought up once we were there.

Kalin Ivany

1668814571

Overall, this was incredible and painless project. Keith worked with us to get our vision for the new siding and windows and walked us through the plan and process. Vicente was an excellent project manager, and we were so happy with the crew. Siding installation was quick, and I really appreciated how the crew cleaned up at the end of each day. Alex and his team were fantastic with the paint; Oscar’s gutter installation was stunningly quick; Rigoberto’s work finishing the punch list items brought it all together. Kari was so responsive with questions and finalizing our project on the back end. When you end such a big upgrade and can’t think of anything you would have done differently, it’s such a relief. From start to finish, working with CSR (Bellwether) was wonderful.

Kim Ruhland

1666972827

Colorado siding repair (now Bellwether) is certainly interested in providing the best service and workmanship possible. Their siding crews are excellent, taking great care and pride in installation to the customer’s satisfaction. Communication is excellent . Paul, one of the owners, in particular, personally ensures that everything is done accurately and to your specifications. When you get a bid, they are not high pressure and give you a fair estimate,, unlike some of the other five-star rated companies we interviewed .We are very pleased that we chose them over three or four other bids. The results were excellent and would not hesitate to use them for any other services they provide.

Had to get a siding repair done for one of the homeowners my company works with doing Solar and this company was great to work with! They were able to keep myself and homeowner up to date with when the project was starting and was done to satisfaction. Karen with accounting was very helpful when it came to payment as well

Marissa Hammond

1666124771

Had a great experience getting new siding on my whole house. The process was super fast and everyone on the team was so nice. Steve was an awesome salesman and Angel and his install team did such a great job. I would highly recommend if you want new siding.

M Forrester

1665678965

We were very pleased with the work done by Bellwether Siding. We needed replacement siding, but the profile we have is no longer available. They were flexible in making sure the work done was what we actually needed. I especially appreciate that they were willing to do a smaller job, just three walls, rather than the whole house.Alejandro, the crew lead, was excellent. Great communication and follow up.

Scott Lawson

1663712802

CO Siding did a great job replacing the siding on our house! Completely PRO throughout the whole process from sales to completion. On time and on budget. Communication throughout was perfect too. I highly recommend them and I’ll use them again without hesitation.

Randy Glassman

We had a great experience from initial conversation through sales to production completion. We replaced all windows and full hole siding. Most impressive was their crew’s working timeline and respect of my property during construction. I highly recommend Colorado Siding Repair.

Melisha Westbrook

1661444888

We had a wonderful experience with Colorado Siding Repair. We had new siding installed and exterior painting done. They were professional and the crews cleaned up before they left every day. The communication from the entire team was excellent and they followed through with every scheduled date. Once project was complete we were so pleased with the finished product!

I had talked to several former customers before deciding to hire Colorado Siding Repair, so I was confident they would do a good job. But they exceeded even my most optimistic hopes. From start to finish, in all aspects, this project was executed professionally. Tom was a very helpful and patient salesman. He never pressured us or used “hard” sales tactics. He answered our questions honestly and worked with us to keep the project within our budget. He positively influenced our color and style choices and told us exactly what to expect.Once the project commenced, everything ran like clockwork. The logistics were daunting, but there were no delays due to missing materials or equipment. I was awed by how well the job was planned.We had an amazing crew. I just can’t say enough about this team. Marco, Isaias, Suany, Nury, and Sebastian . . . they were all fantastic. They were careful, meticulous, hard-working, thorough, conscientious, supportive of each other — you couldn’t ask for a better team. Even as temperatures exceeded 100 degrees, they put in long days and were ready to do it again early the following morning. There were no surprises or challenges they couldn’t handle. No matter what, they would just get it done.Rigo took care of the final punch list items and he too was excellent – every last detail perfect.The final invoice was for the exact amount we had agreed to at the beginning, even though I know there were some surprises and unexpected material costs. At project completion I feel that Colorado Siding Repair delivered MORE than they promised. Before we started this project, I was worried about the cost. In the end, I’m really glad we did it and feel it was money well-spent.We love how our home looks now. It’s a vast improvement; all of our neighbors say so too. It is also a great relief to have siding that won’t burn, and to know that I’ll never have to paint the house again.I would unreservedly recommend Colorado Siding Repair to anyone. I only wish that I could hire them to remodel our bathrooms.

We’ve worked with six or seven contractors over the past two years while remodeling our house. Colorado Siding Repair was one of the very best. I would recommend them to anyone.

Ross Levin

1657648558

Colorado Siding Repair replaced the cedar soffit and fascia with Hardy board on our entire house. The whole process from proposal, planning, prep, execution and cleanup all went smoothly. Communication was spectacular with both verbal and written explanations of what to expect leading up to the work and then texts and emails during the installation. Folks were accessible at all times for questions during the project. All the employees we interacted with showed a positive attitude and seemed to be happy to be part of Colorado Siding Repair.

Christine Perez

1656438519

We used Colorado Siding and Repair for a very complicated exterior siding removal and replacement. Their staff was very responsive and answered all of our questions before, during and after the project. Their installers were on time every day, worked extremely hard throughout the project and did an excellent job. We had just moved into the house and this was a very stressful project for us. Colorado Siding was extremely helpful and competent in explaining the process and timelines and responding to our concerns. After the project was over they completed a walk through to answer our questions and found areas where minor touchups could be done. We were very happy with the finished work. We would definitely use them again for future needs.

Martha Griego

1656038420

They did siding on our home and the men they sent were so professional and communicated in what they were doing. They would ask where we wanted mail box, address, etc. I would highly recommend them.

Ken Grimes

CSR installed all new siding on our home, and they did a fantastic job! The work crews were very thoughtful and professional with their workspace and cleanup. The office staff was friendly and easy to work with as well. We are very happy with this contractor and with the new siding job on our house–highly recommended!
