Siding in Chilmark, Massachusetts

Chilmark is served by Eversource, so homeowners are fully Mass Save eligible. The siding itself isn't rebated, but pulling the cladding is the cheapest moment to add cavity insulation, air-seal, and on exposed shoreline elevations, address the wall assembly properly.

Mass Save typically covers weatherization at 75% or more after a free Home Energy Assessment, and the 0% HEAT Loan can finance qualifying envelope work. Many of Chilmark's seasonal builds were never properly insulated for year-round occupancy. The rebated envelope work behind new siding has clear payback for owners shifting toward longer shoulder-season or full-year use.

Chilmark requires a building permit for residential re-siding through the town Building Department. The Martha's Vineyard Commission has Districts of Critical Planning Concern across most of Chilmark, and the town's strict zoning and conservation rules mean exterior changes often draw multiple layers of review — Conservation Commission for the substantial Wetlands Protection Act buffer along ponds and the shore, and historic-district consideration for the Menemsha and Chilmark Center areas. With a 44-year median build, lead RRP applies to the older stock and asbestos-cement shingle occasionally appears on mid-century cottages.

Re-siding a typical Chilmark single-family runs roughly $18,000–$40,000 for vinyl, $22,000–$45,000 for insulated vinyl, and $28,000–$60,000 for fiber-cement. White cedar shingle — the near-universal visual choice up-island — generally lands $30,000–$90,000 for a full wrap depending on grade. Vineyard labor runs well above the state baseline because of ferry logistics, lodging, and a seasonally constrained labor pool, and review-board permitting timelines add carrying cost.

Chilmark is a Martha's Vineyard up-island town of about 1,561 year-round residents but roughly 1,613 housing units — most of the difference is summer second homes on rural roads and a notable second-home premium per acre. Menemsha, the working harbor, anchors the village.

The median home is around 44 years old, with stock dominated by 1970s–2000s shingled architect-designed beach houses, weathered shake cottages along the stone-walled lanes, and a smaller share of older saltbox-era houses near the Chilmark Center crossroads. Salt-laden wind off Vineyard Sound and the Atlantic, plus intense UV, weather cedar shingle fast and chalk vinyl quickly.
