Massachusetts requires a building permit for re-siding, filed with the Westborough Building Department. Because most homes built before 1978 are presumed to contain lead paint, siding work that disturbs old painted wood must follow the federal Lead RRP rule and use an EPA-certified, lead-safe firm — relevant for the older homes near the center and common. Some older homes carry asbestos-cement (transite) shingles requiring licensed abatement before removal. Subdivision homes with simple layouts permit and install quickly. Reputable contractors pull the permit and flag any lead or asbestos concerns up front.

Westborough siding costs sit near the suburban average, a touch below the inner-Boston ring. A standard vinyl re-side generally runs $12,000–$25,000 depending on size and stories; insulated (foam-backed) vinyl runs roughly $16,000–$30,000. Fiber-cement (James Hardie) lands at $20,000–$45,000 for a whole house, trading higher cost for durability and a clapboard look. Natural cedar runs higher still. Straightforward subdivision homes come in toward the lower end, while older homes near the center that need sheathing repair or asbestos abatement during tear-off push toward the higher end of each band.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential siding work; ask for the registration number and check it before paying a deposit.
