How We Saved a Historic Stained Glass Window in West Roxbury — A Sill Restoration Case Study
The Challenge
When the homeowner of this charming West Roxbury property reached out, the issue was immediately visible: the wood sill beneath their decorative stained glass window had suffered years of moisture exposure. Layers of paint were peeling, the wood was crumbling, and structural integrity was at risk.
Many contractors would have recommended a full window replacement — an expensive option that would have meant losing the original stained glass, a defining architectural feature of the home.
We had a better idea.
Our Approach
At Whole Window, we specialize in historic wood window repair across the Greater Boston area. For this West Roxbury project, our team:
Carefully removed the rotted wood without disturbing the stained glass panel above
Rebuilt the sill using rot-resistant materials designed to withstand New England weather — a process we've refined through years of rotten window sill repair work
Primed and painted the new sill to match the home's existing trim and historic character
Sealed all joints to prevent future moisture intrusion
The Result
The before-and-after speaks for itself. The stained glass window is preserved exactly as the original craftsmen intended, the structure is now solid for decades to come, and the home's curb appeal is fully restored — all at a fraction of the cost of full window replacement.
Why Restoration Beats Replacement
Historic windows in Boston-area homes were built with old-growth wood and craftsmanship that simply isn't available today. When you replace them, you lose:
Original architectural character
Superior wood quality
Often, irreplaceable details like stained glass
Restoration preserves all of this — and typically costs significantly less than replacement.
