Everyone on their team was friendly and professional. After the job was complete they followed up to make sure we were happy and asked if we had any concerns. They did a great job.

  • Working within the restoration industry I routinely need to refer my customers to many different tradesmen outside of my expertise. Colorado Siding Repair consistently exceeds my expectations with the responsiveness to both myself and my clients and does amazing work! The value they bring with their consultative and educational process is a breath of fresh air! For jobs both large and small they show amazing attention to detail and communication!"

  • We had a fabulous experience with CSR. We worked closely with Cash for every detail from design, color, financing and timing. He made it fun and easy! I would highly recommend them!"

  • I would give these guys 100 stars if I could! I am VERY, VERY picky about this kind of work being done on my house and I couldn't recommend them more highly! Cash was our sales rep and he never pressured me in any way. He presented all options to me equally and let me decide if I wanted to move forward and what level of siding to choose. One of our huge issues is that our 1970 house was roasting in the summer and freezing in the winter. He suggested that we put new insulation in as part of the project (although he made NO promises that it would help with heating/cooling of the house). We both HOPED it would and let me tell you, with these upper-90 degree days, we are completely, totally comfortable in our house now. WOW!
    I have never in my life seen a group of guys work so hard on a project. Emerson and the rest of the crew who worked on our house were here 12-14 hour days, always smiling, positive, friendly with us and each other, professional.....AND SUPER respectful of our property. I am a freak about my flowers and grass and during this entire project, the siding crew did not injure one blade of grass or one petal on one flower. They cleaned up thoroughly at the end of each day as well.
    I added a few things along the way to the project, including wrapping the existing beams (would highly recommend doing this), and Cash, as well as the crew, were happy to do so and did this quickly and professionally.
    Our house honestly looks like a brand new house. I realize it costs a lot of money to reside a house and it's a big investment. So of course, you want to choose a reputable, honest company that does great work. Colorado Siding Repair is that company. This is the best money we've ever spent! One of my neighbors told me that he'll never be able to sell his house now because ours looks so good - ha! He is looking at doing siding next year - I hope he chooses this company!
    Thank you, Colorado Siding Repair!

  • Knowledge of the problem I was experiencing. I was included in the discussion of how to best resolve the problem and why. The work looks wonderful, the workers were all professional and timely, and I was extremely happy with the process and results.

  • I needed help with a problem that I could no longer could take care of myself since I have battling Multiple Sclerosis and a fractured femur in my right leg. No one else could even be bothered with this small repair job. Cash came out and did the repair at a very reasonable price. I can’t thank him enough.

    Douglas B.
  • Cash came out and gave an excellent consultation. He described exactly what needed to be done to repair my siding.

    Justin S.
  • All facets of the project have been easy, from the original estimate, through the quote/contract, and now the work is done. I worked with 3 crews: demolition and replacing battens/facia; paint prep that caulked the whole house; and the guys that replace all my gutters. All three crews were great. Cash and Paul were easy to work with as well. Strongly recommend them for your project.

    Kelly M.
  • I hired CO Siding Repair for my rental home that was going on the market for repairing and replacing damaged siding and they did a great job at a fantastic price. I've passed their number on to my friends with rental properties and private homes who have had recent hail damage and encouraged them to give them a call. I highly recommend them!

    Jordan M.
  • Very professional and honest. Quotes are clear, lower than competition and truly honest in assessment of work or repairs to be done. Cash went the extra mile to address all questions and concerns.

  • Colorado Siding Repair was a pleasure to work with and did excellent work!! We contracted them to do a large hail damage repair project on our house - it included a full roof replacement (including a section of the house that had cedar shakes under multiple layers of composite, so required sheeting), gutters, window replacement and modification (replacing a sliding door with a window), and painting of the entire house. It was a complex project, and they coordinated the teams to consolidate work as much as possible, and make it as easy as possible for us in terms of scheduling. We worked with Cash and Paul, and I can't say enough about how pleasant and efficient they were. The work teams were also great, and did an excellent job of cleaning up after each project - especially the roofers, using a magnet to clean up all the nails, which is a huge plus for a home with small kids. And the quality of workmanship on every component is excellent. We will definitely be calling them again for future projects!

    Shay C.
  • Cash is great to work with. Does what he says he is going to do. Followed up with me, explained EVERYTHING and was patient in dealing with the extra hoops needed on an insurance claim and pricing is competitive. This company was recommended to me and I highly recommend this company to others.

    Diana S.
  • We worked with Cash, Paul, and foreman Mario on a big siding, gutter, painting job. Absolutely pleased with these guys, from the workmanship and attention to detail to their work ethic and honesty. We've done a lot of work on our house and CSR is one of the rare teams that compel me to go out and write a review.
    They helped us stage colors and design, stayed on budget, worked quickly and effectively, and did very clean quality work. Clean cuts, extra coats of paint, flashing on everything (which was painted to match), clean angles where there were grades, caulk dyed to match, ongoing supervision of the workmanship.
    Highly recommended.

    Paul L.
  • Excellent job. Worked hard and die good work.

    Annette E.
  • They went above my expectations and had to move a lot of my junk to do their job. Took care not to damage my roses which I had planted across the front of my house. When I called or texted with a concern, they would always respond quickly. I’m a stressed person and worried about everything, they helped by addressing all my concerns. So far this is by far the best experience I’ve ever had with hiring someone to work on my home. They treated my property as if it was their own!

    Darlene F.
  • Colorado Siding Repair is a rare company to find. Their willingness to get the job done right and continue to strive for complete customer satisfaction is unlike anything I have encountered in the construction industry. Cash and Paul are terrific human beings guided by their integrity and honesty. Despite several set-backs, they showed every day and always made sure we knew they were going to do everything they could to make us satisfied.

    Ryan M.
  • The project went smooth from start to finish. They started exactly when expected and ended when as they said. They did a good clean job. Our house looks so good now. The rates were very competitive and I believe we got a great deal! I am getting compliments all the time. It was money well spent. You can't go wrong with this company!
