Open-cell and closed-cell polyurethane foam that air-seals and insulates in one application — installed on roof decks, walls, and crawl spaces throughout Polk County.
In Polk County, spray foam earns its cost in two places: the roof deck and the crawl space or block wall. Applied to the deck, closed-cell foam turns a vented attic into a conditioned one and adds measurable racking and uplift resistance to the sheathing — not a small consideration in a part of Florida that plans its year around hurricane season. Applied to walls, it fills the irregular cavities that batts never quite fit, which is common in older Polk County construction.
Foam is the right answer in Polk County when the ductwork is in the attic and the house is fighting humidity, and the wrong answer when the roof is near the end of its life. We will tell you which situation you are in before we quote it. Spraying foam to the underside of a roof deck that needs replacing in three years is an expensive way to make a future re-roof harder, and no honest Polk County contractor should sell it.
Polk County sits in Florida Climate Zone 2 — hot and humid, with a longer cooling season than almost anywhere else in the country. Under the Florida Building Code, Energy Conservation (8th Edition), the ceiling minimum here is R-38 and framed walls are R-13. ENERGY STAR recommends R-49 for an uninsulated attic in this zone; we build to R-38 to R-49 as the practical target.
| Item | Value | Where it applies |
|---|---|---|
| Open-cell foam | R-3.7 per inch | Roof decks, interior walls, sound control |
| Closed-cell foam | R-6.5 to R-7.0 per inch | Roof decks, crawl spaces, block walls, flood-prone areas |
| Air sealing | Effectively eliminates envelope air leakage at the application surface | Both types |
| Vapor behavior | Closed-cell is a Class II vapor retarder at 1.5" and above | Closed-cell only |
We inspect the attic, roof deck condition, duct location, and any existing insulation, and confirm the roof has enough service life left to justify foam.
Existing insulation is removed where required, penetrations are prepped, and the work area and HVAC returns are masked and protected.
Foam is sprayed in controlled lifts to the specified thickness, checked with a depth gauge as we go rather than by eye.
The space is ventilated per the manufacturer's re-occupancy schedule before anyone goes back in.
We measure thickness, photograph the finished surface, and hand over documentation for permits, insurance, or a future sale.
Spray foam in Polk County typically runs $3.00 to $7.00 per square foot depending on foam type and thickness. A full closed-cell roof deck encapsulation on a 2,000 sq ft Polk County home usually lands between $6,000 and $13,000; open-cell on the same deck is meaningfully less.

Polk County sits in Florida Climate Zone 2 — hot and humid, with a longer cooling season than almost anywhere else in the country. The Florida Building Code, Energy Conservation (8th Edition) sets a R-38 minimum for ceilings in this zone, and R-38 to R-49 is the practical target for comfort and utility savings. Many Polk County homes built before 2005 still measure R-11 to R-19, which is a large part of why their summer bills run high.
Yes, and it is a large share of what we do in Polk County. Wet insulation does not recover — it mats down, loses its R-value permanently and holds moisture against your framing. We remove it under containment, document the condition for your insurer, dry and treat the deck, and reinstall once the cause is repaired.
