Great value, great team, and great results!"

"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."

Siding questions, answered by experts

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. 

Yes, you can shou sugi ban existing siding, but it might pose a hazard to wooden structures, shouldn’t involve treated wood, and must be done by a siding professional. You can not char wood on a house without first removing the boards, so it’s a more complicated replacement project than other siding types.

To clean painted aluminum siding, use a mixture of mild detergent and water applied with a soft brush or sponge. Rinse thoroughly with a garden hose to remove soap residue. For stubborn stains, cleaning aluminum siding with a power washer on a low-pressure setting can be effective. But avoid using high pressure, which could damage the paint.

Bleach can be an option if you want to kill mold and mildew clinging to your siding. However, you must water bleach down to the right concentration of a 1/2 cup of bleach per gallon of water to avoid damaging your siding. Bleach can also harm plants in your yard and isn’t safe to use near pets, so employ it with caution.

Local pressure washing services often offer non-bleach options that can powerfully remove mold and mildew.

You should install your cedar shake siding with the rough side exposed. The smooth side is less resistant to weathering over the years, and the rough side gives your home a more rugged aesthetic. The rough side also takes to paint better and ensures any paint job will last longer before needing to be redone.
