Open-cell and closed-cell polyurethane foam that air-seals and insulates in one application — installed on roof decks, walls, and crawl spaces throughout Yulee.
In Yulee, 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 Nassau County construction.
Foam is the right answer in Yulee 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 Nassau County contractor should sell it.
Yulee 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 Yulee 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 Yulee home usually lands between $6,000 and $13,000; open-cell on the same deck is meaningfully less.
Not sure spray foam is the right call? These are the other scopes we run in Yulee — and the Yulee insulation overview covers the whole envelope.
Loose-fill fiberglass or cellulose blown to a consistent, verified depth across Yulee attic floors — the fastest way to bring an under-insulated attic up to code.
Blown-In Insulation in Yulee →Pre-cut fiberglass and mineral wool batts fitted between studs, joists and trusses in Yulee homes, additions, garages and light commercial framing.
Batt Insulation in Yulee →HEPA-filtered vacuum removal and disposal of wet, contaminated, storm-damaged or rodent-infested insulation from Yulee attics, walls and crawl spaces.
Insulation Removal in Yulee →Attic, wall, floor and air-sealing work for Yulee houses, condos and townhomes — the whole envelope handled by one contractor instead of four.
Residential Insulation in Yulee →Envelope, mechanical and fire-rated insulation for Yulee offices, retail, restaurants, hotels, medical buildings, warehouses and cold storage — including night and weekend work in occupied space.
Commercial Insulation in Yulee →Spray foam in Yulee 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 Yulee home usually lands between $6,000 and $13,000; open-cell on the same deck is meaningfully less.

Yulee 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 Yulee homes built before 2005 still measure R-11 to R-19, which is a large part of why their summer bills run high.
We answer the phone 24 hours a day, 7 days a week. In Nassau County we can usually be on site for a free assessment within 24 to 48 hours, and emergency insulation removal after a roof leak or storm gets same-day priority whenever we can make it happen.
Most Yulee residential jobs are completed in a single day. Larger homes, full removals and commercial scopes in Nassau County run two to four days. We give you a firm window before we start and we call if anything changes.
Cooling is roughly half of a typical Yulee electric bill. Bringing an under-insulated attic up to a properly air-sealed R-38 to R-49 commonly cuts the cooling portion by 20 to 30 percent — more if your ductwork runs through the attic. On a $300 summer bill that is usually $30 to $45 a month back.
It depends on the building and the budget, and we will tell you honestly which applies. If your attic is at R-13 and you want the most improvement per dollar, blown-in to R-38 to R-49 with proper air sealing is the answer. If your ducts are in the attic and you want humidity control, closed-cell spray foam on the roof deck is the answer. If your roof is more than twelve years old, do the roof first — we will say so.
Yes, and it is a large share of what we do in Nassau 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.
These are the outside sources we work from. None of them are ours — check them yourself before you sign anything with any contractor.
Written, itemized, and no obligation. We answer the phone 24 hours a day.
