A lot of older houses were framed long before today’s standardized dimensions, so window openings can vary from room to room and even from one side of the house to the other.

Over the years, houses settle, framing bows, plaster thickens, trim gets layered, and past repairs leave behind their own footprint.

What Smart Homeowners Ask Before Replacing Windows

Before placing an order, homeowners should check the opening conditions, the wall construction, and whether the existing frame is worth keeping.
