The Yamato Road corridor — stretching from I-95 east through central Boca Raton — is home to a dense concentration of residential communities built in the late 1980s and 1990s. These homes were constructed during a period when Florida's insulation requirements were significantly lower than today's standards, leaving many attics with R-values well below the current R-38 minimum.

Advanced Attic Preparation & Air Sealing
Before blowing in new high-density fiberglass, our crews execute meticulous air sealing and insulation removals. We safely extract worn-out, contaminated materials, then seal up the micro-gaps around your drywall seams and light fixtures. This extra step stops hot, humid attic air from leaking directly into your living spaces, optimizing your new insulation's R-value.
