How It Works

Three states of the same window.

Restoration is not a single operation. It is a sequence of decisions about what to keep, what to remove, and what to upgrade — made opening by opening, component by component.

What twenty years of weather does to a wood window

Failure rarely starts at the glass. It starts where water sits: the bottom rail, the sill, the joint where the finish film cracked three winters ago. By the time fogging appears, the assembly has usually been telling you something for a while.

Wood decay
Sustained moisture in the rail and sill
Fogged glass
Perimeter seal fatigue in the insulated unit
Failed glazing
Shrunken bedding compound and split bead
Air leaks
Compressed weatherstrip, out-of-adjustment hardware
Single pane
No sealed cavity, no coating, no argon
