How Injection Foam Works
- What Injection Foam Actually Is
Think shaving cream that turns into a wall's best friend.
What makes it different from everything else you could put in a wall:
It fills 100% of the cavity — no voids, no gaps at the top, no missed corners around obstacles
It never settles. Blown cellulose and fiberglass compact over the years and leave the top of every cavity empty. Cured foam holds its shape for the life of the home
It air-seals as it insulates. The same fill that blocks heat blocks the air infiltration that makes rooms drafty and pipes freeze
It's the highest R-value you can put in your walls without tearing them out
It's safe — non-toxic once cured, Class 1 fire rated, no off-gassing into your living space
Six steps. One day. Zero guesswork.
The estimate — measured, not guessed
Erik — the owner — comes to your home, walks it with you, and puts real numbers on the problem: measurements of your actual wall area, thermal imaging to show where heat is escaping, and a straight answer on what it costs. Free, no pressure, no commissioned salesman working a script.
The before test
On installation day, the first thing we do is a blower door test: a calibrated fan in your doorway that measures precisely how much air leaks through your home. This is your "before" number — in black and white.
Access
- SidingWe remove a course of siding at the injection height — vinyl, aluminum, or original wood — and set it aside for reinstallation.
- MasonryWe drill through the mortar joints (never the brick) with a 5/8-inch bit — a hole about the size of a dime.
- InteriorIf you'd rather we never touch the exterior, we can drill from inside through drywall or plaster, and leave a rough patch at each hole for you to sand, prime, and paint.
Every stud cavity gets located and drilled — including the short ones over windows and doors that other companies skip.
The fill
Foam flows into each cavity until it's completely full. We keep the thermal camera out during the injection, watching cavities fill in real time — if a section isn't filling the way it should, we see it and fix it on the spot, not after your first cold night.
Close up
Siding goes back on. Mortar holes get sealed with new mortar, color matched as close as possible. Drill plugs are set and sealed. We clean up like we were never there.
The proof
The last thing we do is the same as the first: a second blower door test and a final thermal scan. You see the before and the after, side by side — the number, and the picture. Our tests routinely measure at least 25% less air leakage — and up to 50%.
- What The Day Is Like For You
Your day, honestly:
You can stay home.
Most customers do. The work happens outside; inside you'll hear drilling and the rig running — a working-day level of noise, done by dinner.
No demolition, no dust storm.
Your rooms stay your rooms. Nothing inside is opened unless you specifically choose interior drilling.
Pets are fine
keep them inside and away from the work area like you would for any contractor visit.
When we leave
the evidence that we were there is a quieter, more comfortable house and a before-and-after report — not a mess.
