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
- Water entry, drafts or movement at corner joints and projection-window transitions.
- Aging roof caps, seat boards or multi-panel assemblies that no longer seal cleanly.
- Glass, frame or support issues affecting the comfort and appearance of bay or bow windows.
What is usually included
- Inspection of corner seals, support condition, roof-cap transitions and multi-panel glazing performance.

- Checks for weather resistance, fit and curb-facing appearance after service.
