Spray Foam Insulation in Treasure Island, FL

Spray foam insulation in Treasure Island often goes into homes built in the 1950s and 1960s. ACS figures on Point2Homes put 41.4% of homes in those two decades, with a median build year of 1970. Wikipedia lists the city at about 7 feet of elevation, and only 1.54 of its 5.40 square miles is land.

Storm exposure

The National Hurricane Center's Helene report lists a USGS sensor reading of 7.26 feet above mean higher high water at Madeira Beach, just across John's Pass. Homes in Treasure Island took surge and wind-driven rain, and many attics and walls held wet insulation afterward. Removing what got wet comes before anything new.

Second homes and rentals

The 2020 census counted 5,694 housing units in Treasure Island, 33.4% vacant at the time, with a 19.1% rental vacancy rate. Seasonal homes that sit closed up in summer heat stay cooler and drier with a sealed attic and good insulation.

What mid-century homes need

Homes from the 1950s and 1960s usually have thin attic insulation, leaky ceilings and ducts added later in the attic. Sealing the ceiling and insulating to depth, or foaming the roof deck where ducts are present, is the usual starting point. Block walls can be insulated during remodels.

Raised rebuilds

Some Treasure Island lots have been rebuilt with raised homes since the storms. When a new raised home is framed, it is the right time to plan closed-cell foam under the floor and a sealed attic or foamed roof deck. Doing it during construction costs less than retrofitting later, and the materials can be chosen with flood rules in mind.

Working around rentals

For homes rented to visitors, we schedule work between stays and keep the work area contained, then ventilate before guests return.

Code baseline

Pinellas County is Climate Zone 2 under the 2023 Florida energy code, which lists R-38 for ceilings. Many mid-century attics are far below that. Get a free estimate
