"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

For homeowners looking for a less expensive alternative to metal siding, the most popular choice is vinyl siding. At just $3 to $12 per square foot, vinyl siding can cost much less than some types of metal siding. Other popular alternatives include fiber cement and engineered wood. Consult a local siding contractor to determine which type of siding will work best for your home.

The living space of a home doesn’t correlate directly with how many square feet of siding you’ll need, but on average, a 2,000-square-foot home will need 1,700 square feet of siding or 17 squares of siding. Your siding measurements will vary depending on the layout of your home, the number of stories, the size of your doors and windows, and even your roof style.

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.

To maintain vinyl siding, homeowners should regularly clean it with mild soap and water, inspect for damage, and promptly repair any issues. Avoid using high-pressure washing and keep sharp objects away to prevent scratches. Check for mold or mildew and clean with a mixture of water and mild detergent. Take preventive measures to avoid fading, such as minimizing exposure to direct sunlight and using color-safe cleaning products. With proper maintenance, vinyl siding can retain its appearance for years.

You should plan to stain or refinish your home's cedar siding every three to seven years to maintain its appearance and provide maximum protection, though some estimates suggest a range of four to six years. The exact frequency depends on several factors, including your local climate, exposure to severe weather like direct sunlight, rain, and wind, the quality of the initial stain application, the type of stain used, and the overall condition and quality of the wood.

For homes in harsh climates with high humidity and significant sun exposure, you should plan on staining as often as every three years, while those in milder locations may only need to do so every seven years. For the longest-lasting protection in particularly harsh climates, consider using an opaque stain.

If you are looking for a lower-maintenance alternative, you might consider vinyl or aluminum siding. While the initial installation cost can be higher, they do not require as much upkeep and can offer more value over time, especially in areas with excessive rainfall or high humidity.
