Replacing Windows in a Florida Block Home: Sanford Best Practices

Florida block homes make strong shells, but their masonry walls change how you replace a window compared to a wood-framed house.

This guide covers proven practices for Florida block homes, including specification choices, code, cost, and timeline.

Know Your Opening and Choose the Right Install Method

Most block homes in Sanford have a concrete sill, a block or poured lintel above, and a stucco-clad opening with narrow interior returns.

There are two main ways to set a new unit in CMU: a pocket insert or a complete tear-out with buck framing.

Insert installs are cleaner and faster with less stucco repair, while trimming a small amount of glass area due to frame-in-frame. Going full-frame adds substrate control, better flashing options, and full daylight, but it brings stucco cutback and patch time.

On real jobs, pros often blend both approaches, inserting where the pocket is square and dry, and going full-frame wherever the sill shows distress or the old frame is compromised.
