"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."

"The project was phenomenal! At first we needed new siding and then there was Austin! He was an awesome person to get us started with our new siding. He showed us several options before starting the project and then we met Jackie! She was a blast and a breeze to help us with the scheduling of our project. And then there was Darryl the project manager who was very courteous and nice with us throughout the entire install. Germans siding crew was very helpful and even helped my grandmother with some things. We are very satisfied and will trust home genius with whatever we need on our home!"

Siding FAQs, answered by experts

Insulated vinyl siding is very durable and can last for 20 to 40 years. The extra support that the insulation provides helps to make the vinyl siding less susceptible to damages from weather and other minor wear and tear. Vinyl siding on its own may  be less durable than other types of siding like fiber cement, but when coupled with insulation it is stronger than usual.

As stunning and natural as stone siding is, it's not for everyone. Some popular siding alternatives to stone siding include:

  • Aluminum siding

  • Brick veneer siding

  • Engineered wood siding

  • Fiber cement siding

  • Wood siding

  • Vinyl siding

If you want the look of natural stone siding without the high material and installation costs, vinyl siding may be one of the best alternatives. It’s lightweight, low-cost, and low maintenance but does have a lower life span than natural stone.

A square of siding refers to 100 square feet of siding materials. Rather than sell by the individual square foot, manufacturers typically sell siding materials by the square. For instance, if you need 105 square feet of siding but the material is sold in squares, you’ll need to purchase two squares (200 square feet).

Traditionally, you place a layer of ⅜-inch foam board beneath aluminum siding. This gives you a smooth surface to which you can fasten the trim and siding. Beneath the foam board, you should have some kind of waterproof sheathing to further protect your home from water damage. It’s possible this sheathing is already under your current siding.

OSB is a common material used in sheathing, so when OSB prices go up, so does the cost of sheathing. Depending on the economy and supply chain, increased costs can reduce demand, though some homeowners proceed with their projects despite the elevated expenses.
