"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."

Siding questions, answered by experts

While bleach can be effective in killing mold, it may not fully remove mold stains from siding. Additionally, bleach can be harsh and may damage certain types of siding. It's recommended to use specialized mold cleaners or natural alternatives that are safe for your specific siding material as a part of your regular siding maintenance

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.

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.

While almost nothing is completely fireproof, metal siding is extremely fire-resistant. It’s non-combustible so while it may eventually melt in extreme temperatures, it won’t actually light on fire itself. This can add a layer of safety to structures that wood or vinyl siding can’t, making it attractive for industrial use. Metal siding can significantly slow down the spread of a fire, giving extinguishers and firefighters a much better chance at saving the structure and containing the blaze. 

Hail as small as 3/4 inch (about the size of a penny) can cause damage to your siding. When hail reaches 1 inch in size, you can expect to see more cracks, chips, and holes, and hail that’s 1 and 1/4 to 1 and 1/2 inches around will cause significant damage. If you see hail that’s 1 and 1/2 inches to 2 inches or more in size, the damage is likely to be extensive and possibly even dangerous.
