"Our house was in bad shape. Hired this company to do the siding replacement and in 1 and a half weeks we had the whole house re-sided, all debris was cleaned up and I was left with a new house. The communication was executed with top notch professionalism. A trustworthy choice for exceptional siding installation services."

"The work was done efficiently and the end result is great. The crew members were very friendly, courteous, professional, and communication was very good. They did both siding and paint. We got three quotes for this job and Martin and Sons was certainly the most cost efficient option. I will keep them in mind for my next siding and painting projects."

"Colorado siding repair was so wonderful to work with. They came quickly to give us an estimate. The workers came and were SO EFFICIENT. In addition there was no mess left. We could not be happier that they were able to repair the sections without needing to replace all our siding. Thank you Colorado Siding Repair!"

"We loved working with Ernest. He answered every question I had in a very timely manner (within minutes of my text). We have 100% exterior siding (no rock or brick. Our house was a big job and Ernestâ s crew had our James Hardy siding completely finished within 2 weeks and they were able to start immediately. The crew worked non-stop except to break for lunch. I have referred a friend to GS exteriors and I will continue to refer people. I am 100% satisfied."

"After looking for a couple of years and not being able to find a siding company that would smaller jobs, I finally found Colorado Siding Repair. They came out and reviewed the job to replace one wall of siding on my garage that was badly warped. I chose to use a different type than the original, remove a damaged vent, etc. and it came out perfect. They were prompt, kept the work area clean, did some additional finish details to make the front of my house look great. I had one small issue and they promptly came back out and fixed it immediately. I highly recommend this company (and have to several people). They are doing a great service by offering repair/replacement on smaller jobs."

"Very professional from start to finish. My Hardi plank siding had cracks and broken pieces missing. I had to replace that side of my house. Home Genuis did an excellent job replacing my siding. They started on time and finished on time and effectively communicated each step. The Project manager AJ was superb."

"We had siding. roofing, gutters, windows, trim and paint damage to our home. I wasn't sure who to trust. I was referred to Greenslate Roofing and Siding by my neighbor down the street who had them on their roof as well. Joe the owner and his team over at Greenlsate were fantastic easy to work with, they kept me informed of the steps, set expectations and followed through, on top of that we got a great finished product. Greenslate has me as a life long client."

"I recently had my entire home re-sided, with upgraded window trim, full window resealing, and detailed sealing around the perimeter and roofline. The quality of the work was outstanding. Every step was precise, meticulous, organized, and extremely clean. Bryon works with a level of craftsmanship and efficiency that is rare—every cut, seam, and finish was completed with care and accuracy. Equally important, Bryon is a contractor with true integrity. He is honest, reliable, and communicates clearly from start to finish. He documents everything upfront and follows through exactly as promised. As he works, it’s obvious he performs every step he was contracted to do—no shortcuts and no surprises. I’ve worked with more disappointing contractors than good ones over the years, and finding someone with this combination of skill, professionalism, and honesty is exceptional. Bryon has earned my full trust, and he will be my go-to for as long as I own my home. He has my highest recommendation."

Siding FAQs, answered by experts

Regular washing and quick repair of damaged areas to maintain appearance.

Yes, vertical and horizontal siding both come in the same materials, including wood, vinyl, aluminum, and engineered wood. The material you choose can significantly affect your siding’s overall price, lifespan, insulation properties, and maintenance costs. 

Before applying paint to exterior surfaces, filling any cracks or gaps with caulk is essential. Sealing them with a combination of caulk and paint prevents moisture from damaging the paint or decaying the underlying material. You want to ensure the caulk you purchase can be painted over or that you opt for a caulk the same color as the paint.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

Regularly clean with mild detergent, inspect for cracks, and replace damaged sections as needed.
