Old Glass, Real Costs
Original single-pane sashes are beautiful and brutally inefficient. Fairhaven homes feel it doubly: winter winds come up the hill off Bellingham Bay, and the neighborhood's marine air keeps humidity high enough that cold glass sweats condensation onto century-old sills. Many homes here also carry a patchwork of past replacements — a 1970s aluminum slider in one wall, a 1990s vinyl unit in another — none of them sealed to modern standards.
Our approach preserves what matters and fixes what doesn't:
- Matched proportions — tall double-hung and cottage-style units that keep original sightlines and divided-light patterns
- Frame materials chosen for character — fiberglass and wood-clad options that take paint and mimic historic profiles, not just white vinyl
- Full-frame or insert installation, selected opening by opening based on the condition of the existing jambs
- Modern Low-E double glazing that cuts heat loss and street noise while staying visually quiet from the sidewalk
Installation Is Where Historic Homes Get Hurt
Century-old walls are rarely square, and their framing hides surprises — old knob-and-tube wiring near openings, sash-weight pockets that leak air like chimneys, sills weathered soft by decades of southwest storms. We measure every opening individually, insulate the weight pockets, flash sills properly, and rebuild exterior casing details where rot has taken them. That craftsmanship focus is why our work carries a 25-year workmanship warranty; in a neighborhood of hundred-plus-year-old homes, a warranty measured in decades is the only kind that means anything.
We have completed over 2,000 projects around northwest Washington, and the Fairhaven jobs are among those we are proudest to walk past — homes a short stroll from the Village Green and the bookstores on Harris Avenue that look period-correct and now stay warm through a February blow.
See What Your Home Needs
Whether you own a full Victorian, a 1920s cottage on the south hill, or a newer infill townhome near the Taylor Dock boardwalk, the first step is the same: a free on-site estimate. We will go window by window, note which sashes are worth keeping, which are past saving, and what the right replacements will cost — itemized, in writing, with no obligation attached.
