"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 questions, answered by experts

There are several highly durable types of siding that you can build right on top of without removing it, with wood being one of them, provided it's in excellent condition. However, a common reason for siding replacement is to eliminate materials that are in poor condition, making installing new wood siding over old not recommended. Additionally, the cost of adding siding over existing siding can increase costs to between $7 and $13 per square foot.

Yes, vertical and horizontal siding both come in the same materials, including wood, vinyl, aluminum, and engineered wood. The material you choose can significantly affect your siding’s overall price, lifespan, insulation properties, and maintenance costs. 

You can calculate the required square footage of siding you need by measuring the height and width of your home’s rectangular exterior walls. For the triangular-shaped gable walls, measure the height from the ground to the tallest gable point to make sure you have enough for good coverage. Once you have combined the totals for each wall, add another 10% to account for wasted materials. It’s also good to have extra siding on hand to tackle wood siding repair down the road.

Not always. The answer depends on your specific vinyl siding product. While some manufacturers advise against pressure washing, others recommend pressure washing as long as pressure is kept below a certain threshold.

Cracked mortar, loose bricks, water damage, and efflorescence (white powdery deposits) are common problems.
