Somerville’s buildings are overwhelmingly pre-war — original clapboard, asbestos shingles, early aluminum, and first-generation vinyl that’s past its useful life. Each era left different wall conditions behind. We handle all of them.
Full vinyl siding on a typical single-family runs $40,000–$50,000. Hardie and Everlast composite start around $65,000 and go up with trim scope. Triple-deckers are significantly more due to three stories of wall area, scaffolding requirements, and tenant coordination — expect $80,000+ for a full triple-decker reside with premium materials. Complete projects include removal, sheathing inspection, weather barrier, new siding, and PVC trim.
Vinyl is the most affordable — low maintenance, wide color range, solid performance when installed properly. Hardie fiber cement is more substantial, resists impact, and holds its appearance longer. Everlast composite is our primary premium option — factory-finished, fade-resistant, with strong warranties. In Somerville’s competitive real estate market, many owners investing in a reside choose Hardie or Everlast for the curb appeal and long-term value.
Yes — and in Somerville, that’s the majority of our siding work. Three stories of scaffolding, zero-lot-line access planning, tenant coordination, and maintaining weathertight conditions on an occupied building are all standard. We work section by section, floor by floor, and manage the project so residents can continue living in the building throughout.
Most single-family projects take 2–3 weeks. Triple-deckers take 3–5 weeks depending on building size, material choice, and trim scope. Somerville’s access constraints can add time compared to suburban projects, but we build that into the timeline from the start. Clear schedule at signing.
Yes — and on Somerville’s pre-war buildings, there’s almost always something. When we strip old siding, we inspect every square foot. Rot, water damage, and insect damage get repaired before the weather barrier and new siding go on. The sheathing condition behind a 100-year-old triple-decker is never a guarantee.
We strongly recommend it. Old wood trim on Somerville’s pre-war buildings is typically rotted behind the surface even when it looks acceptable from the street. Cellular PVC won’t rot, doesn’t need painting, and gives the exterior a clean, premium finish. On a triple-decker, new trim across all three floors is what ties the whole project together visually.
Yes. With the old siding off and sheathing exposed, it’s the ideal time for continuous exterior insulation. Somerville’s pre-war buildings have minimal wall insulation, and many triple-deckers have balloon framing that allows air to move freely through the wall cavity. Adding exterior insulation during a reside can make a significant difference in heating and cooling costs across all units.
