Vinyl and fiber-cement siding
We install vinyl siding, and James Hardie fiber-cement siding with AZEK trim over a Tyvek weather barrier. Behind the finish, a solid wood base matters: on some jobs the walls get new sheathing before the siding goes on.
Roof and siding from one team
Several of our Google reviewers had us do both. When the roof and the siding are planned together, the details where they meet are handled by the same crew.
“Luis and his team maintains my roof and installed new siding on the whole house. My neighbors have become their customers too.”
