Wildwood's wooded ridges and rolling lots hold some of the largest vaulted attics in the St. Louis area, paired with walkout basements and metal-framed shops that sit wide open to the mixed-humid climate. When a room over the garage won't heat, or your July cooling bill climbs past what you can afford, the culprit is almost always air leakage and thin or missing insulation in the spaces that matter most.
Since 2012, St. Louis Spray Foam Insulation has served Wildwood (63038) and the surrounding areas with spray foam and air sealing for attics, crawl spaces, rim joists, metal buildings and barndominiums. We know how the big vaulted spaces in Wildwood homes behave in summer and winter, and we know how to seal and insulate them right the first time.
Spray Foam Insulation in Wildwood (63038)
Wildwood's newer construction, built from the 1980s onward, brought two-story homes with vaulted great rooms, bonus rooms over garages, and walkout basements that sit on clay and limestone. The vaulted attics in these homes can reach 130 to 150 degrees in July and drop into the teens by January. Standard fiberglass batts or blown-in cellulose settle and compress over time, leaving gaps at the rim joists, band joists, and where the roof meets the walls. Ductwork routed through unconditioned attic space loses 20 to 40 percent of its heating and cooling before the air reaches your rooms. Closed-cell spray foam seals these leaks, holds its R-value for decades, and handles the moisture that swings inward during humid summers and outward during cold winters.
Wildwood's acreage also runs barns, metal buildings and barndominiums that sweat in spring and frost inside in winter. Spray foam insulation on the interior of metal roofs and walls stops the condensation and holds temperature year-round. Our team has been insulating Wildwood homes and properties since 2012, and we understand the building stock and the climate that shapes it.

How a Job Works in Wildwood
We start with a free on-site assessment. We walk your attic, crawl space or rim joist with you, measure the areas to be sprayed, check for moisture or contaminated insulation that has to come out first, and talk through open-cell versus closed-cell foam based on your space and budget. We give you a written estimate that names the R-value, thickness and board footage, so you know exactly what you are paying for.
On the day of the work, our fully insured crew sets up mechanical ventilation to manage the spray odor during application. We mask off areas that need protection, spray the foam to the specified thickness in controlled passes, and let it cure. The smell is normal and temporary. We ask that you stay out of the sprayed space for 24 to 48 hours while the foam hardens and off-gasses. If the space is occupied, we help you plan around that window. If insulation has to be removed first, we haul it out and dispose of it properly before any foam goes down.
When the cure is done, we do a final walkthrough with you, answer any questions, and leave your property clean. We do not leave debris, scraps or overspray behind.
Attic spray foam insulation in Wildwood typically runs from $1.50 per square foot for open-cell to $1.20 per board foot for closed-cell, depending on the R-value and thickness you need and whether existing insulation has to come out first. A 1,500-square-foot attic with open-cell foam to R-38 might run $2,200 to $3,000 before removal. Closed-cell foam costs more per board foot but delivers higher R-value in less thickness, which matters in tight spaces. Wall and injection foam for closed cavities runs from $2 per square foot. Crawl space work starts at $2,500 for a basic spray on rim joists and band joists. Rim and band joist sealing alone runs from $650. Metal building and barndominium work is priced by the square footage and thickness. Insulation removal runs from $950 depending on what is in the space and how it has to be handled. The real cost driver is always the R-value you need, the thickness that delivers it, and what has to be removed or fixed before any foam is sprayed.
