"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."

"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."

"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."

Siding FAQs, answered by experts

A self-etching primer is the best option for aluminum siding. These are specifically designed to bond with bare metals, among other surfaces, leading to better adhesion and corrosion resistance. An oil-based primer is a good alternative if you can’t find a self-etching primer.

The best siding to cover brick is vinyl or metal siding. Vinyl is low maintenance and affordable, while metal is highly durable and offers some of the best insulation on top of brick. Fiber cement is another great option. Though you can install wood siding on top of brick, it’s not as ideal.

The living space of a home doesn’t correlate directly with how many square feet of siding you’ll need, but on average, a 2,000-square-foot home will need 1,700 square feet of siding or 17 squares of siding. Your siding measurements will vary depending on the layout of your home, the number of stories, the size of your doors and windows, and even your roof style.

Yes, new stucco siding can increase your home's value and curb appeal, similar to other new siding materials. Homeowners can expect an average return on investment (ROI) of around 70%. For an average stucco installation costing $5,700, this can translate to a value increase of nearly $4,000. The value can be further enhanced by choosing high-end textures or simulating more expensive materials like brick. Stucco is also a durable, fire-resistant, and versatile material that can last 50 years or more, making it an attractive feature for potential buyers, especially in hotter climates where its insulating properties are beneficial.

Siding pros typically charge by the square foot when providing estimates for siding projects. They’ll take the material cost and add in an estimated labor fee, and some contractors will include an additional upcharge to account for profit, waste, and unexpected issues. Another important price factor your pro will consider is the quality of your home’s current siding, which they’ll need to remove, and your home’s sheathing. If pros have to make any additional repairs to your home’s exterior, the added labor will also influence your final siding cost.
