Hiring a siding contractor in Concord is a meaningful decision. Concord is one of Contra Costa County’s largest cities — suburban, family-focused, and with a housing stock that’s mostly single-family homes from the 1950s through the 1980s. Lots are bigger here than in the core Bay Area, and homeowners tend to stay longer. The renovation market is strong: kitchens and bathrooms that haven’t been touched in 30 years, roofs that are past their lifespan, and a lot of interest in ADU construction now that Concord has streamlined its process.
What to Look for in a Siding Contractor
Siding failure is usually a moisture problem. Old wood siding cracks, loses its paint seal, and starts absorbing water — which gets into the wall system. Fiber cement solves this permanently: it doesn’t absorb moisture, doesn’t rot, and holds paint far longer than wood. We install it correctly — proper flashing, nailing, gaps, and a complete moisture barrier. Verify the contractor’s CSLB licence at CSLB.ca.gov before signing anything. For most siding work, a B (General Building) licence or the appropriate specialty classification is required.
What a quality siding scope includes:
- James Hardie certified installers
- Wood, fiber cement, and engineered wood options
- Complete moisture barrier installation — no shortcuts
- Matching existing profiles on historic homes where possible
- Trim, flashing, and caulking included — complete system
Permit Requirements in Concord
Most siding projects in Concord require permits through the Concord Community and Economic Development. A licensed contractor manages the permit process. Never work with a contractor who suggests skipping permits on significant renovation work.

Old siding loses its seal, lets moisture in, and drives up heating bills.
