Overview & Where it fits
For homes and condos that need the right residential window type for operation, daylight, ventilation and curb appeal.
We review the condition of the opening, how it is used day to day and whether the right path is adjustment, component replacement, glazing work, hardware updates or a larger replacement scope.
Common issues we address
- Failed balances or sash drift that make hung windows hard to raise or keep open.
- Loose tilt latches, worn weatherstripping or rattling vertical sashes.
- Residential windows that no longer lock squarely after frame or sash movement.
What is usually included
- Inspection of balances, sash travel, tilt hardware and locking alignment.
- Recommendations focused on smoother vertical movement and better sealing performance.
- Checks for opening control, lock engagement and final sash fit after service.
