One spray foam company for the whole job — not just the easy part.

St. George sits at roughly 2,860 feet in the Utah desert, in IECC Climate Zone 3B — a genuine hot-desert climate with July highs of 104-106°F and August close behind, followed by a monsoon season that runs mid/late-July through early/mid- September. This is a cooling-load problem, not a heating one, and it applies just as much to a metal shop as it does to a three-bedroom house.

Most spray foam crews in Washington County pick a lane — residential attics only, or commercial metal buildings only — and refer out anything else. We run both, plus the work most companies won't touch: removing and correcting spray foam a previous contractor installed wrong. Off-ratio mix, missing ignition barriers, and incomplete cavity fills don't fix themselves, and they don't pass inspection either.

Whatever brought you here — a hot attic, a sweating metal roof, or a job that needs to be redone right — we quote it the same way: a real site visit, an itemized number, and a crew that installs spray foam every single day.

Complete spray foam insulation for homes, shops & commercial buildings

From attic and roof-deck applications to metal-building condensation control and correcting a previous contractor's mistakes — click any service to see how it works, what it costs, and why it fits Washington County's desert climate.

Attic & Roof Deck

Roof-deck and attic-floor spray foam that shuts down the single hottest surface on a Washington County home, pulling attic temperatures down and taking real load off the air conditioner from May through September.

Closed-Cell Spray Foam

Dense, rigid, R-6 to R-7 per inch spray foam that St. George Foam runs across the toughest applications on our schedule - roof decks, exterior walls, crawl space perimeters, rim joists, and metal building interiors - anywhere moisture resistance and structural add-on matter as much as R-value.

Learn more

Open-Cell Spray Foam

Lighter, more affordable spray foam built for interior wall cavities and attic floors, where air-sealing and sound control matter more than raw density - and where St. George Foam specs it deliberately, not as a discount substitute for closed-cell.

Learn more

Exterior Wall Spray Foam

Open-cell or closed-cell foam sprayed into exterior wall cavities on new-construction framing and open-wall remodels, sized to hit IECC Climate Zone 3B performance targets without over-building the assembly.

Learn more

Crawl Space Spray Foam

Closed-cell spray foam applied to crawl space perimeter walls and rim joists, sealing the vented crawl space out of the thermal envelope and cutting off one of the more overlooked energy-loss points in a Washington County home.

Garage & Shop Spray Foam

Spray foam for attached garages, detached shops, RV garages, and home workshops across Washington County, aimed at turning a space that's unusable half the year into one you can actually work, park, or train in year-round.

Residential and commercial, one crew standard

The same install discipline whether we're in a family attic or a 6,000 sq ft metal shop — no B-team for commercial work.

We fix what other crews got wrong

Off-ratio foam, missed ignition barriers, incomplete fills — we diagnose, remove what has to go, and reinstall to code.

Zone 3B-appropriate, every time

We build to St. George's actual cooling-driven climate targets, not a generic statewide minimum or cold-climate assumption.

Why St. George chooses us

Comfort and savings, built for Washington County summers.

Full-service scope

Attics, walls, crawl spaces, garages, shops, and metal buildings — spray foam is the only material we install, across every scope it applies to.

Zone 3B-appropriate R-values

We build to St. George's actual code targets for a hot-desert climate — not a generic statewide minimum or a cold-climate assumption that doesn't apply here.

Honest, right-sized advice

We recommend open-cell, closed-cell, or a mix based on your property's actual needs — and we won't oversell heating-bill or ice-dam framing that has nothing to do with a St. George summer.

Questions

St. George spray foam insulation FAQs

Yes — that's the core of how we're built. Most spray foam crews in Washington County focus on residential attics and walls and pass on commercial work, or they focus on commercial metal buildings and don't do homes. We run both sides of the business every week: single-family attics and crawl spaces on one truck, metal-building and shop condensation-control jobs on another. If it takes spray foam to solve, we quote it.

Yes, and it's a bigger share of our work than most homeowners expect. Off-ratio foam, incomplete cavity fills, missing ignition barriers, and foam sprayed too thick in one pass are common failure points from crews that don't specialize. We assess what's there, remove what has to come out, and reinstall correctly — see our Spray Foam Removal & Correction service for what that process actually involves.

For most homes, yes — particularly when the attic and roof deck are the target. Those two months are when Washington County's cooling load peaks, and a sealed, foam-insulated attic assembly means your AC system spends less time fighting radiant heat gain from a 130-150°F+ roof deck. Rocky Mountain Power customers may also qualify for Wattsmart Homes program incentives that help offset the upfront project cost.

Most residential projects run roughly $1.50 to $5.00 per square foot installed, with open-cell foam toward the lower end and closed-cell toward the higher end because of its denser chemistry and higher R-value per inch. Commercial and metal-building projects are priced by scope and square footage after a site walk. Because Washington County's climate is entirely cooling-driven, none of the cost drivers you'd see in a cold-climate market — ice-dam prevention, snow-load venting changes — apply here. We'll walk your specific property and give you a firm, itemized quote.
