Siding.

Modern siding, installed as a system

Modern siding upgrades enhance curb appeal and provide year-round protection. CS1 installs vinyl, fiber cement and engineered wood as a complete system — housewrap, flashing and trim — not just panels on a wall.

New siding is the single biggest curb-appeal upgrade a home can get, and one of the few that pays back in both comfort and value. Properly installed cladding with a continuous moisture barrier keeps water out of the wall assembly, while added insulation board trims heating and cooling bills every month it’s on the house.

Frequently asked questions

Vinyl, fiber cement and engineered wood, matched to your home’s style, budget and exposure.

Will new siding lower my energy bills?
