"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!"

"Our experience with GS Exterior Experts and Ernest was top notch. We had two other estimates for JamesHardie siding before we signed with GS Exterior Experts. Cheaper is not always better, so we were a little anxious about our choice. When we read all the great reviews about GS Exterior Experts we figured we made the right choice. The crew came and worked non stop until the job was done. We could not believe how fast and efficient they were. Done in 3 days and quality work. We were so thrilled and amazed with the job, we ended up giving each of the crew a tip! We could not be happier with our siding and gutters. We highly recommend Ernest and GS Exterior Experts."

"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 questions, answered by experts

You cannot install clapboard siding on a bare, unprepared surface. Clapboard siding requires a clean, sturdy base made from plywood or similar materials, sometimes called backerboard. Then, it needs an underlayment or sheathing, a moisture membrane to help protect the exterior wall.

Note that sometimes clapboard siding is caulked as it’s installed for additional protection. We don’t suggest this: Caulking the siding can trap moisture inside the clapboards and lead to moisture damage over time. The siding needs some space to “breathe,” especially in rainy weather.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.

The average cost to install stucco siding on a home is around $5,700, with most homeowners paying between $2,200 and $9,100. However, the total cost can range from $750 to as high as $22,750 depending on several factors. On average, you can expect to pay between $7 and $9 per square foot. Key cost factors include the size and complexity of your home, the desired color and texture, labor and material costs in your area, and whether you have a multi-story home. Specific applications have different costs, such as adding stucco over brick ($7 per square foot) or over wood siding ($8.50 per square foot). To save money, you can consider removing the old siding yourself or scheduling the installation during the off-season.

Traditionally, you place a layer of ⅜-inch foam board beneath aluminum siding. This gives you a smooth surface to which you can fasten the trim and siding. Beneath the foam board, you should have some kind of waterproof sheathing to further protect your home from water damage. It’s possible this sheathing is already under your current siding.

Fiber cement shingle siding is made from a blend of common ingredients, including cement, sand, water, and wood or cellulose fibers. The composition of the mixture varies depending on the manufacturer, however, with some makers opting to include special additives to improve longevity and resilience, and some include dyes and pigments to create custom colors that don’t require painting.
