Attic Insulation & Air Sealing in Naples, FL

Attic Insulation & Air Sealing is usually the most direct way to make a Naples house easier to cool. Under a dark shingle or tile roof in August, attic air gets far hotter than the outdoors. Every gap in the ceiling, from a recessed light to the space around a plumbing vent, lets that heat and the moisture with it pull into the rooms below whenever the AC creates even a slight pressure difference.

Seal, then insulate

We start by closing the holes: the attic hatch, top plates, wiring and plumbing penetrations, dropped soffits over kitchen cabinets, and the open chases common in homes built before the 1990s. Foam, caulk and fire-rated sealant each have their place. Only after that do we add insulation, so new material is not sitting over open leaks.

How deep is enough?

The 8th Edition (2023) Florida Building Code, Energy Conservation lists R-38 for ceilings in Climate Zone 2, which includes Collier County. Many attics in older Naples homes have a fraction of that, crushed down by years of AC service trips.

Blown-in or spray foam?

If the attic is vented, open and easy to reach, blown-in fiberglass or cellulose over a sealed ceiling is usually the lower-cost path. If the ducts and air handler are up there, or the roof is being replaced, foam on the roof deck may be the better investment. We price whichever options fit.

Signs your attic needs work

A ceiling that feels warm on a summer afternoon, an AC that runs nearly nonstop, dust streaks around ceiling vents and light fixtures, and insulation you can see the ceiling joists through are all common signs. We check each one in person.
