Full-frame and insert window replacements for Somerville homes — proper flashing, sealed transitions, PVC trim, and energy-efficient glass for triple-deckers, Victorians, and multi-family buildings. Google Guaranteed. 150+ five-star reviews.
Somerville’s triple-deckers and multi-families were built with the windows of their era — wood double-hungs, many with weights and pulleys, some replaced once already with early vinyl that’s now fogging and drafty. With property values climbing and energy costs up, window replacement is one of the highest-return upgrades a Somerville owner can make.

Somerville’s housing spans a narrow band — mostly 1890s–1930s triple-deckers and Victorians. But the window conditions vary widely depending on what’s been done to them over the decades.
Most whole-home projects range from $25,000 to $75,000+ depending on window count, frame type, and installation method. Triple-deckers and multi-family buildings with more units and openings will be higher — a full triple-decker window replacement across all three floors is a larger project than a single-family home. We provide a detailed written estimate after measuring on site.
It depends on the condition of your existing frames. If the wood is solid, square, and dry, inserts save time and cost. If there’s rot or water damage — which is common on Somerville’s pre-war triple-deckers and Victorians — full-frame replacement is the better long-term investment because it lets us properly flash and seal the opening. We inspect every window and give an honest recommendation.
Andersen, Marvin, and Pella for premium fiberglass and wood-clad options — popular in Somerville where homeowners want to maintain or upgrade the building’s character. Harvey and Mathews Brothers for high-quality vinyl when budget is a priority. We help you choose based on the building, your energy goals, and what you’re trying to achieve.
Most single-family or single-unit projects take 3–5 days. A full triple-decker across all three floors takes longer — typically 1–2 weeks depending on window count and installation method. We protect interiors, flooring, and landscaping throughout, and coordinate with tenants on multi-family buildings.
Yes — and that’s a significant portion of our Somerville window work. We coordinate across all units, schedule work to minimize tenant disruption, and can phase the project floor by floor if needed. Exterior trim is installed consistently across all three floors so the building looks cohesive when finished.
Yes — often significantly. Many Somerville triple-deckers still have original single-pane windows or early double-pane replacements from the 1990s that have lost their seal. Modern low-E coated, argon-filled double- or triple-pane windows dramatically reduce heat loss in winter and heat gain in summer. In a triple-decker where heating costs are split across units, the savings add up quickly.
Yes. Somerville requires building permits for window replacement. We handle the application, coordinate with Inspectional Services for inspections, and ensure the work meets current energy code.
