Longfellow Design Build

Sandwich requires a building permit for re-siding, filed with the town Building Department. Crucially, exterior changes within the Old King's Highway Regional Historic District — including new siding or a change of material visible from the public way — require committee approval before work starts. Homes built before 1978 are presumed to contain lead paint, so siding work that disturbs old painted wood must follow the federal Lead RRP rule and use an EPA-certified, lead-safe firm — common given the town's age. Some homes carry asbestos-cement (transite) shingles requiring licensed abatement. Coastal flood-zone lots may have added flashing requirements. Reputable contractors handle the permit, route any historic application, and flag lead or asbestos concerns up front.

Sandwich siding costs run near the Cape average, slightly above inland central Massachusetts because of travel and coastal-grade materials. A standard vinyl re-side generally runs $12,000–$25,000; insulated (foam-backed) vinyl runs roughly $16,000–$30,000. Fiber-cement (James Hardie) lands at $20,000–$45,000 for a whole house, and natural cedar shingle or clapboard — the traditional material in the historic core — runs higher still. Antique homes in the Old King's Highway district can cost more because of period-matched materials and the added review step, and detailed flashing on coastal lots pushes those jobs toward the top 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.
