Window Types
Custom Windows
One-off assemblies, oversized units, and discontinued factory profiles where no replacement part exists in the supply chain.
Common failure modes
- Discontinued hardware
- Unavailable profiles
- Non-standard glass sizes
- Mixed-material joints
Restoration approach
Profile knives ground to match the original section, hardware sourced or fabricated, and units built to the measured opening.

Casement
Side-hinged sash operated by a crank. Excellent seal when adjusted correctly, but hardware wear and sill exposure make them the most common restoration candidate.
Awning
Top-hinged units that shed water while open. Their horizontal bottom rail collects moisture and is often the first component to fail.
Double Hung
Two vertically sliding sash. Restoration focuses on balance systems, parting stops, and the meeting rail seal that governs air infiltration.
Fixed
Non-operating units in direct-set or sash-in-frame configurations. Failures are almost always glazing- or frame-related rather than mechanical.
