"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."

"All the work went well. Paulo was very professional and responsive. We had a few delays that were out of his hands - mostly due to suppliers who were behind schedule. Nothing major, but Paulo communicated about all of these in a timely fashion. We replaced all of our vinyl siding with James Hardie board. Also replaced several exterior windows. Paulo also replaced all of our old gutters. Everything was painted to order including old soffets and fascia. Someone touched up the drywall texturing around the new windows and then painted everything to match. The work was done efficiently. They paid attention to detail and fabricated nice trims around outlets and utility vents. My only gripe would be that they didn't leave the roof clean, and after the first rain, I found a lot of debris and nails that had blown down into the yard and driveway. Everybody on his crew was friendly and respectful. There was always at least one person on site who spoke perfect English."

Siding FAQs, answered by experts

Yes, cedar is a popular option for shou sugi ban siding, which is a Japanese style of charring wood for a home’s exterior to finish and protect the material. Cedar shou sugi ban siding costs $15 per square foot on average, but ranges between $2 and $25 per square foot depending on your home’s size, the price of labor, and where you live.

Oil-based stains are preferred over latex or water-based varieties because your home's cedar siding must constantly withstand the weather conditions in your location. These stains provide better penetration into the wood to more effectively protect it from UV rays and water infiltration. Oil-based stains are available in transparent, semi-transparent, opaque, or solid-color selections to achieve the look you desire.

If you’re wondering how to clean clapboard siding, the approach depends on its material and condition. Siding in good shape may need only light soap and spray from the hose, while older siding often requires more thorough treatment. For serious cleaning, power washing can remove caked-on dirt, but you should consider hiring a professional to avoid causing damage in the process.

Yes, you can mix siding types to create a unique design. However, it requires thoughtful planning to execute properly. The installation process will also be more time-consuming than if you were to choose either vertical or horizontal for the entire home, so it will cost you more in labor and design costs. 

Wood siding requires an air gap behind it to allow water to drain out, and for air circulation and venting to allow humid air to escape and keep the material from rotting due to moisture.
