Spray foam insulation questions, answered for St. George

Most residential projects in Washington County fall between roughly $1.50 and $5.00 per square foot installed, with open-cell foam at the lower end and closed-cell at the higher end. The exact number depends on the application (attic floor vs. roof deck vs. crawl space vs. exterior wall), total square footage, and access. We give firm pricing after an on-site walkthrough, not a blind phone quote.

A standard residential attic or crawl space job is usually completed in a single day. Larger whole-house new-construction jobs, full roof-deck conversions, or commercial metal building projects can run two to several days depending on square footage and access. We give you a specific timeline as part of the written estimate before work starts.

Yes, once properly cured. A correctly installed job is typically safe to re-enter within a few hours, and the initial installation odor generally clears within a day or two in St. George's low humidity. A chemical smell that lingers for weeks usually points to an off-ratio or improperly cured install, which is something we address directly through our removal and correction service.

Open-cell cures to roughly R-3.5 to R-3.7 per inch, costs less, and excels at air-sealing interior spaces like partition walls and vented attic floors. Closed-cell cures to roughly R-6 to R-7 per inch, resists moisture, and adds structural rigidity, making it the right choice for roof decks, crawl space walls, rim joists, and metal buildings. Most projects use a combination of both, matched to each specific area of the job.

Both. We run dedicated crews and lift equipment for commercial and metal building projects -- warehouses, self-storage facilities, agricultural buildings, pole barns, and shops -- alongside our residential attic, wall, crawl space, and garage work. It's a core part of the business, not a side offering.

Yes, this is a regular part of what we do. We diagnose off-ratio or improperly cured foam, wrong product for the application, missing code-required ignition-barrier coatings, and failed inspections, then mechanically remove only the sections that actually failed and re-spray to a standard that passes inspection and resolves the underlying issue.

We can discuss financing and payment options during your estimate -- reach out to 844-967-5247 or josh@contractorschoiceagency.com and we'll walk through what's available for your specific project size and scope.

Yes. We apply code-required ignition or thermal barrier coatings anywhere foam is left exposed to living or storage space, and we coordinate directly with builders, GCs, and local inspectors on new-construction and remodel jobs so the insulation passes rough-in and final inspection without delay.

We're based in St. George and serve all of Washington County, including Washington City, Hurricane, Santa Clara, Ivins, and the LaVerkin and Toquerville area. Call 844-967-5247 to confirm service for your specific address.

Yes, our installation work is backed by a workmanship warranty, and the foam products themselves carry manufacturer warranties covering material performance. We'll walk through the specific warranty terms that apply to your project during the estimate.

For most residential attic, crawl space, or wall jobs, you don't need to leave the home, though we recommend staying out of the immediate work area (like the attic or crawl space itself) while spraying is underway. We'll walk you through any specific precautions for your project before we start.

Spray foam typically reduces your home's overall cooling load, which can improve how efficiently your existing system runs rather than requiring a resize. If you're planning a roof-deck conversion that moves ductwork into conditioned space, we'll flag anything worth discussing with your HVAC contractor as part of the project.
