Foam is soft, so we don't use it. Every gap is closed with galvanized steel mesh, putty and concrete.
The CDC notes a mouse can fit through a hole the width of a pencil, about 1/4 inch. So we seal the small gaps too, inside and outside the house.

How rodent proofing works
Neighbors said it best.
4.9out of 5 from 344 reviews on Thumbtack (opens in a new tab)
After three other companies failed to stop the rats from getting into our basement, these guys finally did it. They found a tiny gap behind the HVAC unit that everyone else had missed.
They sealed everything up, including mesh screwed into areas in the beams where they could get into the attic. They also discovered our furnace was slowly leaking water into the crawl space, which was creating mold!
Atticali has been highly professional, punctual, and responsive. … Entire process right from first visit, estimate, payment, and service was seamless.
The garage door seals were failing and mice were just wandering in like they owned the place. … No more unwanted visitors in my garage!
