Spray Foam Insulation in Naples, FL

Spray Foam Insulation in Naples, FL is less about keeping warmth in and more about keeping the attic's heat and the Gulf's humidity out. Naples Airport normals for 1991 to 2020 put the average high near 91 F in both July and August, and the hot, wet season runs from May through October. In a home with the air handler and ducts in the attic, that attic heat goes straight into what you pay to cool the house.

We are spray foam insulation contractors who also blow loose-fill, seal attics and remove old insulation, so the quote you get is not built around a single product. Sometimes foam on the underside of the roof deck is the right call. Sometimes a well-sealed attic floor with deeper blown-in insulation does the same job for less. We explain which fits your house before you sign anything.

Why so many Naples homes are under-insulated

Much of the city's housing predates today's energy code. American Community Survey estimates (via Point2Homes) put the median year built in Naples at 1983, with roughly 40% of homes built from 1960 to 1979. Insulation from that era has often settled, been crushed by service work, or been soaked by a roof leak. The current Florida Building Code, Energy Conservation (8th Edition, 2023) calls for R-38 in ceilings in Climate Zone 2, which covers Collier County. Many older attics hold far less.

Closed cell vs open cell spray foam

Open-cell foam is lighter and softer, costs less per square foot, and is commonly used under roof decks to create an unvented, conditioned attic. Closed-cell foam is denser, has a higher R-value per inch, adds rigidity and resists moisture, which makes it the usual pick for metal buildings, block walls that take wind-driven rain, and places where water is a concern. Which one has the highest R-value? Closed cell, per inch. Which one fits your house depends on the surface, your roof and how the attic is ventilated now.

Spray foam insulation cost in Naples

National guides put installed spray foam at about $1.50 to $5.00 per square foot (HomeGuide), with open cell at the low end and closed cell at the high end. A spray-foamed attic in an existing home runs about $2,500 to $12,000 by Fixr's figures. Your attic size, roof pitch, foam type and thickness, and whether old insulation has to come out first all move the number. We measure and give you a written estimate, and that estimate is the price.

Is spray foam insulation worth it in Florida?

It often is when the ducts and air handler live in the attic, when rooms over the garage or under a low-slope roof stay hot, or when a re-roof exposes the deck. It is less likely to pay off on a wide-open attic floor with no ductwork overhead, where air sealing plus blown-in insulation may cost less.

We work across Collier County and just over the line in southern Lee County. In the city of Naples and Pelican Bay, much of the work is in condos, villas and older single-family homes close to the Gulf, where elevation is only a few feet and flood rules shape how homes have been rebuilt. North Naples, Vineyards, Island Walk and Verona Walk lean toward 1990s and 2000s homes in gated communities, where attic upgrades and roofline foam come up when a roof is replaced. Golden Gate, Golden Gate Estates and Orangetree are inland, with larger lots, more detached houses, and more garages and outbuildings. To the south, Lely, Lely Resort and Naples Manor mix older ranch homes and newer planned neighborhoods. Marco Island, Goodland, Everglades City and Chokoloskee sit at the water's edge and have all been hit hard by hurricanes. Ave Maria and Immokalee round out the inland side of the county, and Bonita Springs and Estero are just to the north.
