Injection Foam Inside
Injection foam can be done from the inside of a home or…
Injection Foam Outside
the outside of a home depending on your project or time of year for project completion.
Injection foam inside and outside:
One of Our Core Capabilities that sets us apart
2lb Closed-Cell Pour Foam (Existing Walls & Retrofits): A highly specialized "drill and fill" service that very few contractors can offer. We can inject premium insulation into existing, closed walls (including residential drywall and concrete block) without tearing down your walls.
From the Outside: We carefully remove pieces of your siding, drill access holes, fill the cavity completely, and seamlessly replace the siding.
From the Inside: For brick or stone homes, we drill and fill from the interior—ideal for rooms undergoing remodeling or refinishing.
The Wisconsin Climate Advantage: Most retro-foam or injection operations use lightweight 1/2lb open-cell foams that absorb moisture. We use dense, 2lb closed-cell pour foam, which creates a true, 100% moisture vapor barrier essential for freezing Wisconsin winters, while delivering twice the R-value per inch of the competition.
“The Builder’s Advantage: Because we are licensed building contractors with 30 years of carpentry experience, we don’t just drill holes blindly. We know exactly how your walls were built. Whether carefully removing and replacing exterior siding or working around delicate interior trim, our construction background ensures your home’s structural integrity remains flawless.”
Injection foam can be completed both inside and outside using the same technique. Holes are drilled inbetween the studs from the base of the wall to the ceiling. Foam is injected into the lowest holes until the foam is done reacting and expanding. The foam will “puff”out the hole created at the lowest point first. Once it is done reacting foam is injected into the next level hole until the process is complete, and thus repeating the process until all levels of holes are filled. Once all the holes are filled, and the reaction is complete, the excess foam that has “puffed” out of the holes are cut off flush with the drywall (indoor)/outside wall with the siding removed (exterior). All cavities are checked for “voids”. Any voids will be filled by drilling a smaller hole and using a quick fill technique. this process is completed using 2lb, closed cell, slow-rise injection foam. All surfaces are thoroughly covered to protect indoor items from foam overspill.
An example of what it looks like when the wall cavities are completed and filled. “Puffs” are out meaning only drying time left and then they will be cut off flush with the wall and cleanup will commence.

Once the process is complete and the “puffs” have been scraped flush, the inside projects are ready for plaster and paint, the outside projects are ready for siding.
Injection foam has a number of other applications, it can also be used to “Foam Jack” sunken concrete slabs and sidewalks. More to come on that in the near future. Check back often for new content on FOAM JACKING and other Injection Foam applications.
