Wood Window Repair in Boston, MA

Need a window repair?

Boston has some of the oldest and most architecturally significant housing stock in America. Federal-style townhouses on Beacon Hill date to the early 1800s. Victorian brownstones in the Back Bay and South End rose between 1860 and 1900. The triple-deckers of Dorchester, Roxbury, Jamaica Plain, and West Roxbury defined working-class Boston between 1890 and 1925. Charlestown rowhouses go back further still. What unites them is original wood windows that have outlasted a dozen replacement window companies — and that, with proper care, will easily outlast a dozen more.

Whole Window is a wood window repair specialist serving Boston homeowners, condo associations, and historic property managers across every neighborhood. We don't sell replacement windows. We restore the original wood windows that define Boston's architectural character — fixing rotten sills, rebuilding sash cords, repairing frames, replacing glass, and weatherstripping for modern energy efficiency. Boston homeowners who choose repair typically save 50–70% on the total cost compared to replacement.

What makes Boston wood window repair different is the architectural diversity. We work on brownstones in the South End, triple-deckers in Dorchester, Federals in Beacon Hill, and mid-century homes in West Roxbury — each requiring different techniques and historical sensitivity. Our shop is at 1819 Centre St in West Roxbury, centrally located within Boston's city limits and within easy reach of every neighborhood.

Why Boston Wood Windows Are Worth Saving

The original windows in Boston homes — particularly those built before 1940 — were made from old-growth pine, mahogany, fir, or chestnut. These trees grew slowly in dense forests, producing wood that's two to three times denser than the plantation-grown pine in modern replacement windows. This is why your 1885 South End brownstone window can still be sound after 140 years while a 2005 vinyl replacement next door already has failed seals.

Common Boston window problems we address:

Brownstone window deterioration — Many Back Bay and South End brownstones have windows where the masonry has settled, putting stress on the frames. We can repair frame distortion without disturbing the surrounding masonry.
Triple-decker sash cord failures — Dorchester, Roxbury, JP, and West Roxbury are full of three-deckers where every window operates by sash cord and pulley. When cords fail, the windows stop working — we restore them while replacement companies refuse.
Beacon Hill historic district homes — Beacon Hill's strict preservation requirements mean replacement is rarely permitted. Repair satisfies historic district guidelines.
Failed glazing on harbor-facing exposures — Homes in East Boston, the Seaport, and along the waterfront face salt air and moisture that breaks down putty over decades. Reglazing brings these windows back to airtight performance.
Multi-unit building windows — Many Boston buildings are condos with shared exterior responsibility. We have experience coordinating with condo associations and property managers.

Our philosophy: identify exactly what's wrong, repair only that, preserve the original character. An 1890 South End window with sound frames and rotten sills doesn't need replacement — it needs rotten sill repair. A drafty Dorchester triple-decker doesn't need a $1,500 replacement — it needs a sash cord restoration and weatherstripping.

Wood Window Repair Services for Boston Homes

We provide a full range of wood window repair services across Boston:

Wood Window Repair — Comprehensive restoration for original wood windows in Boston brownstones, triple-deckers, Federals, and Victorians.
Rotten Window Sash Repair — When the bottom rail of your sash has rotted, we cut out the damaged section and splice in new wood matched to the original profile rather than replacing the entire sash.
Rotten Window Sill Repair — We mill replacement sills from rot-resistant wood, install with proper flashing, and slope them to shed water for the next 50 years.
Sash Cord & Pulley Repair — A Boston specialty. Almost every pre-1950 Boston home has rope-and-pulley sash systems. We restore them when modern installers won't touch them.
