What Residential Spray Foam Involves

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.

When You Need It

This fits new home construction, additions, and whole-home retrofits — especially older homes in the area that were built with minimal or outdated insulation. Persistent drafts, uneven room temperatures, and high heating bills in winter are common signs a home could benefit from an upgrade.

Meeting Wisconsin's Energy Code

Wisconsin's energy code (SPS 322) sets minimum R-value requirements and moisture control rules that apply to residential insulation work. Following these isn't just about passing inspection on new construction — the vapor retarder and ventilation requirements apply to any dwelling with insulation installed, which matters for retrofits too.

What Affects Cost

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.

Planning Around Curing Time

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.

Common Questions
Can spray foam be added to existing walls without tearing them open?

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.

Will spray foam reduce noise between rooms, not just outside?

Yes, to some degree. Spray foam's density helps dampen sound transmission through walls, which is a common secondary benefit homeowners notice alongside the energy savings.

How long does residential spray foam installation take?

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.

Does spray foam help with drafts around windows and doors?

Spray foam is excellent for sealing gaps around framing, but window and door seals themselves are usually a separate, smaller sealing task — ask us about addressing both in the same visit.
