The Importance of Accurate Measurements for Custom Windows

In historic structures, movement over time leaves you with crooked jambs and varying plaster depths, so you cannot assume uniformity.

I map the frame profile, stool projection, and existing reveal so the new window lands flush with interior trim without odd gaps.
