Our main insulation · Attic

Droppings, nests and soiled insulation taken out, so the attic starts fresh.

Crawl space
Debris, droppings and damaged insulation cleared out from under the house.

Crawl space
White sheeting over the soil that keeps ground moisture down.

New flexible insulated ducts in place of chewed or crushed ones.

Part of rodent proofing

How rodent proofing works

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!
