"It went very well! They showed up on time and addressed all the concerns I had. Jeremiah went through everything with us and was able to have it done in no time. We’ve had contractors before and they would say they would get it done by those time and it would never be done by the time they would say. We were very happy and pleased that they had it finished when they said they would. They did amazing work and I would recommend them to anyone!"

"Jared was on time. It was a little cool for painting the porch but he power washed the deck. Came back later and did 2 coats to the deck floor and 1 coat to the railings and lattice. He is very quiet, works constantly. He always cleans up any mess."

Siding FAQs, answered by experts

Vinyl siding will fade slowly over time but will likely be most noticeable starting 10–15 years after installation. This timeline varies based on factors such as the climate where you live. In areas with more extreme hot or cold conditions, vinyl is likely to fade more quickly.

Siding and cladding are two popular exterior wall coverings that protect homes from the elements and provide insulation, but they differ in design and application. Siding is applied directly to a home’s exterior, providing some insulation and basic shielding from the elements. In contrast, cladding is installed indirectly over furring strips, creating a ventilated air gap for enhanced insulation and moisture control.

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. 

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.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.
