Doors measured, set square, and sealed
Entry, interior, French, and sliding doors fitted to the opening, shimmed level, sealed where needed, and trimmed to finish.
Overview
Doors that sit square, latch cleanly, and keep the weather out, which is entirely down to how the opening is prepared and the unit is set.
What door installation involves
Most door complaints — sticking, dragging, drifting open, draughts — trace back to how the unit was set rather than the door itself.
The opening is measured and checked, the unit is shimmed plumb and square, the reveal is made even, exterior units are sealed and flashed, and the trim is finished on both sides.

What you get
Set plumb and square
A door that binds or swings on its own is almost always a setting problem. Units are shimmed and checked rather than simply screwed in.
Weather sealing on exterior doors
Flashing, sealing, and threshold detail are part of an exterior installation, because that is where water and draughts get in.
Trim finished both sides
Casing and any required jamb extensions are installed and finished, so the job is complete rather than functional but unfinished.
Before & after
Completed door installation projects will be documented here with same-angle before-and-after photography.
