"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 FAQs, answered by experts

If you’re wondering how to make wood siding last longer, including Composite T1-11, inspect it annually or quarterly to spot and repair cracks, holes, or chipped areas. You’ll also want to re-stain the wood every 3 to 5  years or repaint every 7 to 10 years for protection (note that repainting requires stripping and sanding off old paint as well). Lastly, keep up with regular cleanings using a garden hose or low-pressure power washer to help prevent grime and discoloration.

Regularly wash with mild detergent, inspect for rust, and repaint as needed to maintain its appearance.

Vinyl siding is the cheapest option in terms of upfront costs. The average cost to install vinyl siding is around $12,173, with certain types like vinyl shake, clapboard, or dutch lap costing as little as $2 to $3 per square foot. While vinyl is very low-cost, it may not last as long as natural materials or metal, with a typical lifespan of 20 to 40 years. In contrast, metal siding is more expensive initially but can save you money in the long run due to its longer lifespan, which is often double that of vinyl. It's recommended to consult a siding professional to determine if the lowest-cost option is the best material for your specific home.

Increasing home value and return on investment (ROI) are two different things and it’s important to differentiate between the two. While a kitchen remodel will surely raise the value of the house, it may only have an ROI of around 50%. Homeowners looking to raise the value of their home for sale will have to consider how much they will recoup by the monetary investment in projects, as the ROI percentages may be lower or higher than the added value on a dollar-for-dollar basis.

Caulking should be re-applied roughly every five years. It's natural for a home to settle and separate caulking from joints, so it's a good idea to assess the home every two years. A consistent siding maintenance schedule will help you see if the caulking is needed and address any potential issues before they occur.
