Wood Window Repair in Boston, MA
Need a window repair?
Restore your wood windows. Don't replace them.
Most window companies will tell you your old wood windows are beyond saving. We disagree. At Whole Window, we specialize exclusively in wood window restoration across the Greater Boston area — saving homeowners 50–70% compared to full replacement while preserving the character of their home.
Why repair instead of replace?
Original wood windows in Boston-area homes were built with old-growth lumber that's denser, more durable, and more rot-resistant than anything available today. A properly restored wood window can last another 50+ years. Replacement vinyl windows typically last 15–20 years before needing to be replaced again.
Repair also preserves the architectural integrity of your home — especially important in historic neighborhoods like Beacon Hill, Back Bay, Brookline, and Jamaica Plain.
What we repair
Our wood window repair services cover every part of your window system:
Rotten window sills — wood splicing, epoxy consolidation, profile matching
Rotten sashes — full sash rebuild or epoxy restoration
Rotten frames — structural repair before damage spreads
Sash cords and pulleys — restore smooth operation in double-hung windows
Glass and glazing — replace fogged units, reglaze with traditional putty
Weatherstripping — seal drafts, reduce energy bills
Hardware — locks, latches, lifts, balances
Screens — custom window screen repair and replacement
Reglazing: putty is a wear part
Glazing putty holds the pane, seals it, and sheds water off the glass. It hardens and cracks after twenty to thirty years, and it goes first on the south and west sides of the house where the sun is hardest. Once it fails the glass rattles, water sits against the muntin and the rail, and rot starts exactly where repairs cost the most. Reglazing is routine maintenance on a wood window, and it is the piece most often skipped.
How we reglaze a sash
Old putty is softened and removed without scorching the wood or breaking the glass
The rabbet is cleaned to bare wood and primed with oil primer. This is the step most often skipped, and it is why some putty jobs fail in three years instead of thirty
Glass is bedded in a thin layer of putty so it sits on a cushion, not on bare wood
Glazing points hold the pane mechanically. Putty is a seal, not an adhesive
The bevel is run in one pass and left to skin over before painting
Paint is lapped slightly onto the glass, which is what keeps water out of the putty line
Fresh putty does not cure in a deep freeze or in full August sun, so in New England this is spring and fall work.
Restoration pricing, window by window
Most restoration jobs combine three things in the same visit. These are the prices we charge in the Boston area:
Reglazing a sash, $275 to $495 per window, depending on the number of panes, the condition of the old putty, and access
Sash cords, $125 per side and $250 per sash for both cords, or $290 per sash to convert to chain
Bronze weatherstripping, $175 to $345 per window, depending on whether one sash or both are done
Done together in one visit, a full restoration of a single window generally runs $500 to $1,000. Booked separately that is three trips to the house. Every job gets a written estimate before work starts.
We do not install replacement windows. Repair and restoration is all we do, so there is no version of the estimate where it turns out you need new units.
