"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

How long siding takes to install depends on various factors, but averages seven to 14 days for a 1500 to 2000 square foot home. You may have a longer installation timeline if your house is large or architecturally complex, if you have underlying damage beneath the existing siding, or if the weather delays the installation process.

The most significant benefit to mixing siding styles is the visual appeal and intrigue you can create. Multiple colors or textures will make your home stand out, boosting curb appeal and home value. Mixing siding styles also lets you take advantage of the high resale value of stone without having to pay the high cost of covering your entire home with it. Coupling stone and vinyl means pairing affordability and value. Plus, you’ll often only have to pay for a partial siding replacement when it comes time to replace one of the materials.

Siding colors that go well with a green roof include off-red, beige, white, gray, brown, and even another green. Don’t be afraid to get creative with your green roof. This roof color has character, and playing with your color palette can really add to the natural charm of the house. 

Both vinyl and metal are very popular siding options, and it’s important to weigh the pros and cons of each before making a decision for your home. Vinyl has a lower price point than metal and is easier to install, but metal siding is more durable, longer-lasting, and requires much less maintenance. The upfront costs could save you money in the long run.

The main differences between dutch lap versus clapboard siding have to do with their design and texture. Clapboard siding features flat, beveled planks stacked at a slight angle, offering a simple, traditional look. Dutch lap siding features a subtly concave surface along with a notch that creates a shadowed look between the boards. This eye-catching design often resembles wood grain and introduces a noticeable shadow line, making it more visually interesting compared to the simpler look of clapboard siding.
