"I had Martin & Sons replace some siding damaged by age and water, and also paint. Martin was with the crew supervising and working the whole time. The house had a special "notched or grooved" siding that doesn't seem to be made or readily available according to a couple of different contractors. Martin customized the siding to perfectly match the existing siding. Next day the painting crew came to paint the whole house. They did a great job, and even painted my shed which we hadn't discussed, but it definitely needed it. Overall very happy with cost and quality of workmanship!"

"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."

"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."

"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

Though vinyl siding is affordable, the material may not last as long or look as good as other siding materials. For example, wood siding has a beautiful, natural appearance but requires much more maintenance to keep your siding looking as good as new. 

Fiber cement siding is another alternative that mimics the appearance of wood siding. Like vinyl siding, fiber cement is a low-maintenance material, but it does come at a higher price and is heavier and more difficult to install. Weigh the pros and cons of all siding materials before you decide on the best option for your home.

If you’re wondering how to make wood siding last longer, including Composite T1-11, inspect it annually or quarterly to spot and repair cracks, holes, or chipped areas. You’ll also want to re-stain the wood every 3 to 5  years or repaint every 7 to 10 years for protection (note that repainting requires stripping and sanding off old paint as well). Lastly, keep up with regular cleanings using a garden hose or low-pressure power washer to help prevent grime and discoloration.

While vinyl is the less expensive option, composite siding has been known to be more durable than vinyl. In addition, because it is made from recycled materials, it is a more ecologically-friendly choice. Composite siding is also more luxurious looking and comes in a much wider range of styles and colors.

Vinyl siding will fade slowly over time but will likely be most noticeable starting 10–15 years after installation. This timeline varies based on factors such as the climate where you live. In areas with more extreme hot or cold conditions, vinyl is likely to fade more quickly.

When it comes to fiber cement siding maintenance, it’s not too much work. However, it needs to be painted about every 15 years and may need to be re-caulked to prevent mold. Be sure to also wash your fiber cement siding with a lower-powered garden hose at least twice a year to avoid buildup and fading as well.
