University City's 1910s-to-1930s brick and stucco homes around the Loop face a hard insulation problem: third floors that bake in summer and basements that stay cold all winter, with attics and rim joists that leak conditioned air year-round. St. Louis Spray Foam Insulation has been sealing and insulating these older homes since 2012, and we know exactly why your heating and cooling bills climb while comfort stays out of reach.
The brick walk-ups and apartment buildings that define University City (63130) were built well before modern insulation standards, and their solid multi-wythe walls, flat roofs behind parapets, and floor joists set into brick pockets over basements create the same thermal weak spots in nearly every unit. Our crews work in University City and across the St. Louis area, and we specialize in the tight attics, narrow rim joists, and enclosed wall cavities that make spray foam the only practical answer.
Spray Foam Insulation in University City (63130)
University City's housing stock is almost entirely pre-1940s construction: brick and stucco buildings with solid exterior walls that have no cavity insulation, flat or low-slope roofs, and basements that sit on fieldstone or brick. The attics in these homes swing from 130 to 150 degrees Fahrenheit in July to well below freezing in January. The rim joists where the first floor sits on the basement wall are almost always open to the foundation, and the crawl spaces beneath older buildings collect humidity and condensation that kills blown-in fiberglass. Closed-cell spray foam seals these spaces completely, stops air leakage, and handles the moisture that makes this city's climate so hard on older insulation.
We have been installing spray foam insulation in University City and across Greater St. Louis since 2012. We measure every job on site, specify R-value and thickness in writing, and use only the equipment and technique that the manufacturer requires. Our team is fully insured with general liability and workers' compensation coverage for every project.

How a Job Works in University City
We start with a free on-site visit to your home in University City. We look at the attic, crawl space, rim joists, and any walls you want sealed. We measure the area, talk through open-cell versus closed-cell foam, and explain what has to happen before we spray. If old insulation has to come out first, we tell you that upfront and price it honestly. We give you a written estimate with R-value, thickness, and board-foot total before we schedule the work.
On the day of the job, our crew sets up mechanical ventilation in the space being sprayed. We apply foam at the manufacturer's specified ratio and drum temperature, pass by pass, to the thickness you approved. The space has to be ventilated during cure and for twenty-four to forty-eight hours afterward, and we tell you plainly when the area can be safely occupied again. If you are living in the home during the work, we coordinate the schedule to keep disruption to a minimum.
When the foam cures, we clean up and walk through the finished work with you. You leave with a written record of what was sprayed, where, and to what R-value and thickness. That documentation is what you need if you ever sell the home or file an energy efficiency tax credit.
Attic spray foam in University City typically runs from $1.50 per square foot for a straightforward top-up to higher costs if old insulation has to be removed first. Rim joist and band joist sealing starts around $650 for a standard basement perimeter. Wall injection foam for closed cavities runs from $2 per square foot. Crawl space foam starts at $2,500 depending on square footage and moisture conditions. Insulation removal alone starts at $950, and full insulation replacement including removal and new foam starts at $2,800. The actual cost depends on how much area needs coverage, the R-value and thickness you choose, whether old insulation has to come out, and how tight or difficult the access is.
