Why Boston windows need repair
Boston has some of the oldest housing in the country — brick row houses and brownstones in Back Bay and the South End, Victorians in Jamaica Plain and Dorchester, and thousands of triple-deckers. Many still have their original wood windows, and most sills and brick molding are decades past their last real repair.
Coastal nor'easters, wind-driven rain off the harbor, and repeated freeze–thaw cycles push water into every open paint crack. Once water reaches bare wood, rot starts at the sill and spreads into the sash and frame.
Signs your windows need repair
- Drafts or cold spots near the window in winter
- Fog, condensation or moisture trapped between the panes
- Cracked, chipped or broken glass
- Soft, peeling or discolored wood on the sill or sash
- Window is stuck, won't stay open, or won't lock
- Torn screens or bent screen frames
