Siding in Lexington, Massachusetts

Lexington is in Eversource territory, so homeowners qualify for the full Mass Save program. Mass Save does not rebate siding itself, but the free Home Energy Assessment unlocks heavily subsidized weatherization — and a residing job is the ideal moment to use it, since the walls are open. Adding continuous exterior foam or upgrading house wrap and air-sealing under new clapboard is exactly what the program supports, typically at 75% or more for insulation when paired with the assessment.

That matters most in Lexington's leaky antique colonials, where the original wall cavities are often uninsulated. Sequencing the assessment before you reside lets the crew dense-pack or add exterior insulation while the old siding is off, capturing comfort and fuel savings. Insulated vinyl is an option on non-historic homes, but on contributing structures the commission usually steers you toward wood, so the energy gain comes from what goes behind the siding rather than the siding itself.

Lexington requires a building permit for siding replacement, and historic review is the defining wrinkle. Properties in the town's historic districts — including the Battle Green and East Village districts — fall under the Historic Districts Commission, which reviews any exterior change visible from a public way. The commission generally expects clapboard or wood shingle in matched profiles on contributing structures and frequently declines vinyl, so get a determination before ordering. Pre-1978 homes, which describe most of the historic stock, trigger the EPA RRP lead rule and require a lead-certified crew for any disturbance of old paint. Mid-century homes with asbestos-cement shingle siding need licensed abatement before removal.

Lexington runs at the high end of state pricing. A standard vinyl re-side on an average home falls roughly $14,000–$26,000, and insulated vinyl runs $18,000–$32,000, but both are limited to non-historic streets. Fiber-cement (HardiePlank) typically lands $24,000–$48,000 installed depending on size and trim detail. Matched cedar clapboard or wood shingle on a historic colonial commonly runs $35,000–$70,000-plus once custom milling, priming, and review are factored in. Pre-1978 lead-safe handling and any asbestos-shingle abatement add to all of these, and larger estate-class homes near the center push past the top of every range.

Lexington is one of the most affluent towns in Massachusetts, about 34,200 residents, built around the Battle Green at the Revolutionary War site. The housing runs from antique colonials and Federal-era homes near the center to the well-known mid-century modern enclaves architects laid out across town in the 1950s and 60s.

That split drives two very different kinds of siding work. The antique colonials carry painted clapboard or wood shingle that homeowners usually want matched in kind rather than swapped for vinyl, and many sit in regulated historic districts. The mid-century moderns more often run vertical board, T1-11, or early panel systems that owners replace with fiber-cement or cedar. Both ends trend toward premium materials and higher labor, making Lexington one of the costlier towns in the state for residing.
