How To Measure The Opening The Right Way

Start with the rough opening, not the old sash or the interior trim. You want the width and height of the opening at three points each, because older homes are rarely square.

Record the smallest width and the smallest height, then let the installer or supplier figure out the final fit allowance. That small gap is what gives room for shimming, flashing, and doors Palm Coast FL sealant, all of which matter in humid weather and wind-driven rain.

Florida Code, Permits, And Product Approval

Another frequent problem is forgetting that stucco, tile, or interior trim can hide the true edges of the opening. This is one reason best replacement windows for coastal Florida homes are chosen after an in-person check, not from a few photos and a guessed size.
