Places to Scan and Seal

Electrical Outlets: Scan the electrical outlet wall plate. Remove the plate before foaming. Seal the gap between the outer perimeter of the electrical box and the wall (do not foam inside of the electrical box).

Sink Plumbing: Scan the PVC plumbing under the sink in rooms that are on the perimeter of the house. Seal by filling the gap between the wall and the pipe.

Dryer Vent: Scan the dryer vent from the inside of the house (when the dryer is not running). Seal from either the interior or exterior of the penetration, depending on which you have easier access to.

HVAC Penetrations: Scan first floor registers that are located on the floor. Seal between the penetration and duct work from the basement.

A/C Wiring: Scan where the cooling line from the A/C condenser (look for a copper pipe) that enters the basement from the outside of the house. You will find near where the air conditioning unit sits on the ground. Seal the penetration between the pipe and the wall.

Sill Plate: Scan the walls of an unfinished basement where the wood 2 X 4 or 2 X 6 meets the poured concrete foundation wall. Then seal around the wood framing.

Attic Hatch: Scan the attic hatch door from the living space. Seal by going into the attic and filling the gap between the frame of the attic hatch door and the attic floor.

HVAC Penetrations: Scan the top floor registers, which will more than likely be located on the ceiling. Seal between the penetration and duct work from the attic.
