What looks like a simple swap often turns into a fight with measurements, flashing, insulation, trim, and weatherproofing. One wrong step can leave a home less efficient than before.

A window that is not measured and fitted correctly can end up crooked, hard to operate, and vulnerable to air and water infiltration.
