Blown-In Insulation for Fast, Affordable Upgrades
By late afternoon in July, the upstairs bedrooms are already warmer than the thermostat downstairs. Come January, those same rooms lose heat just as quickly. Many St. Louis houses were built before modern energy codes. They still rely on thin, settled attic layers that can’t keep up with our humid summers and sub-freezing nights. As blown-in insulation contractors, we close that gap fast and give your home the insulation depth it should have had all along.
Foam Co. blows material through a hose into attics and closed wall cavities, where it drifts into every corner. Loose-fill insulation wraps around wiring, piping, and uneven joist bays that pre-cut pieces leave exposed. The result is a seamless thermal blanket that raises your total R-value and trims wasted energy, with no demolition. For many homeowners, it’s the quickest, most affordable upgrade before the next utility bill arrives.
Seamless Loose-Fill Coverage
We feed the material through a hose and spread it evenly across the attic floor. It settles around cables, pipes, vent housings, and odd framing without leaving voids. Most blown-in attic insulation goes right over your existing layer, so nothing gets torn out. In walls, our crew fills each cavity from above or through small access holes until it’s packed full.
Faster, Lower-Cost Results
Attics are where most homes lose the most energy, so a modest investment there goes the farthest. Our blown-in insulation installers finish most attic upgrades in a single visit. You’ll feel cooler bedrooms in August and warmer floors in February. With Foam Co., you can rest assured the crawling, hauling, and cleanup stay off your to-do list.
Material Choices, Minimal Disruption
We match the fill to your goals. Fiberglass stays stable and resists settling. Dense cellulose insulation packs tight and slows air movement. Mineral wool adds sound control and fire resistance. For wall retrofits, we drill small holes, fill each cavity, and patch every opening so it blends in. Your leakiest areas get a high-impact upgrade without a remodel.

About Us
We’ve worked in St. Louis attics from every era. We’ve seen 1920s bungalows with a few inches of old fill, 1970s ranches with patchy coverage, and newer two-story homes built only to minimum code. That experience shows us where blown-in material pays off and where another product fits better. Some homeowners ask about blown-in foam insulation. We’ll explain honestly when loose fill, spray foam, or batts make the most sense for your space.
Our crews arrive on time, protect your floors and belongings, and leave your home as clean as we found it. We bring the same measured approach to houses, commercial buildings, and industrial sites. Read our story to see what shapes the way we work.
Areas We Serve
Our trucks cover the St. Louis metro, the growing towns of St. Charles County, and the river and farm communities of Southeast Missouri. Each area has its own mix of historic brick, suburban split-levels, and newer builds. We plan every residential insulation upgrade around the house in front of us. Travel distance never changes the quality of the fill or the care we put into cleanup. Check our service area page to find your town on the map.
