Whole-home insulation upgrades, additions, and new construction built to meet St. Charles County's energy code. Free quotes for new builds and retrofits alike.
Spray foam is applied directly to wall cavities, rim joists, and other framing, expanding to fill gaps and forming an air-tight seal as it cures. In new construction or during a remodel with open walls, this is straightforward. In existing finished walls, it typically means small access holes drilled at intervals to inject foam into each cavity.
This fits new home construction, additions, and whole-home retrofits — especially older homes in the St. Charles area built well before current energy standards. Persistent drafts, uneven room temperatures, high summer cooling bills, or high winter heating bills are common signs a home could benefit from an upgrade.
St. Charles County's adopted energy code sets minimum R-value requirements by component for new construction and major additions, along with a certificate requirement documenting what was installed. Spray foam's higher R-value per inch makes it a practical way to meet these standards, particularly in tighter wall cavities where a thicker batt product isn't practical.
Square footage, whether open or closed cell foam is used, and whether the walls are open (new construction) or closed (requiring injection) all factor into the price. A quick call gets you an accurate quote for your specific project.
Spray foam expands and sets quickly, but full cure time before a space can be closed up with drywall or used normally is worth planning for. If you're coordinating with other trades on a renovation, let us know your schedule so insulation timing fits into the broader project.
It's more limited than new construction. Existing closed walls typically need small access holes drilled to inject foam, while open walls (during a remodel) can be fully sprayed. We can assess your specific situation on a call.
Yes. Spray foam's air seal works both directions — it keeps conditioned air in during summer just as much as it keeps cold air out in winter, which matters in a climate with hot, humid summers and cold winters like this one.
Most single-family home projects take one to a few days depending on scope, plus curing time before the space can be closed up or used normally.
Spray foam's higher R-value per inch makes it easier to meet the county's prescriptive R-value requirements without adding excessive wall thickness, though your specific project's compliance path depends on the overall design. We can help clarify what applies to your project.
