"Our house was in bad shape. Hired this company to do the siding replacement and in 1 and a half weeks we had the whole house re-sided, all debris was cleaned up and I was left with a new house. The communication was executed with top notch professionalism. A trustworthy choice for exceptional siding installation services."

"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

Vinyl siding is durable, low-maintenance, weather-resistant, and available in various colors and styles. It also provides excellent insulation, improving energy efficiency.

To calculate how much siding you need for exterior walls, first measure the height and width of the rectangular walls. For the triangular gable walls, measure the width and then the height from the ground to the tallest gable point.

  • For the rectangular walls, the calculation is: length x height

  • For the triangular gable walls, the calculation is: (length x height) / 2

Once you add these up, include an additional 10% to account for any wastage.

Signs that you need to replace your siding include siding that’s warping, bubbling, or cracking; signs of rot or mold growth; fading, peeling, or chipped siding or paint; or siding that’s separating from the exterior of your house. Failing to replace your siding when it’s damaged can lead to moisture problems or structural damage, so promptly repair or replace siding as soon as you notice any of these signs.

Generally speaking, the thicker the siding, the higher the quality. Thicker siding provides a stronger resistance against extreme weather conditions. Thicker siding also tends to fade more slowly under the sun. Hardie boards, a popular fiber cement siding option, is usually 5/16 inches thick. Meanwhile, masonry-finished cement siding varies from 5/8 to 5/8 inches thick.

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.
