Windows and Doors That Seal, Fit, and Finish Properly
Window and door jobs go sideways when they get treated like simple swaps. The unit matters, but the flashing, shimming, framing condition, tie-in to siding, trim, and weather seal are what decide whether the install lasts.
KM Construction handles replacement windows, entry doors, patio doors, storm doors, trim, flashing details, and exterior tie-ins. We are a strong fit when the opening needs more than a quick drop-in and you want the finished result to look clean from both inside and outside.
You deal directly with Kyle Mennear, a Red Seal Journeyman Carpenter. KM Construction Ltd. also holds a valid Alberta prepaid contracting licence for qualifying residential renovation contracts involving deposits or progress payments.
Window and Door Replacement Scope
Replacement Windows
Window replacement for existing homes, including sizing, trim, flashing, and tie-ins that suit the surrounding wall assembly.
Exterior Entry Doors
Front doors, side doors, and exterior man doors with proper jamb fit, threshold details, brickmould, and finishing.
Patio and Garden Doors
Patio door replacement and wider opening upgrades where access, glass area, or traffic flow needs improvement.
Storm Doors
Storm door installation and replacement when you need airflow, protection, and a cleaner finished entry setup.
Trim and Exterior Tie-Ins
Brickmould, casing, siding tie-ins, caulking, and finish details so the new unit does not look like an afterthought.
Flashing and Weather Protection
Flashing details and exterior water management that matter more than the sales pitch attached to the unit.
Where Window and Door Jobs Go Wrong
The usual failure is chasing the lowest install price while ignoring the opening itself. Rotten framing, out-of-square conditions, bad thresholds, weak flashing, and poor exterior finish work are what create callbacks and regrets.
KM Construction is a better fit when the job needs carpentry judgment, not just a rushed swap. That includes old homes, tricky patio doors, awkward siding transitions, and openings where the homeowner wants the final look to actually match the house.
