Crawlspace Restoration in Portland, OR
A dry, clean, sealed crawlspace protects the floor above, keeps pests out and stops moisture moving into your home.
Crawlspaces are out of sight, so problems go unnoticed. Rodents tunnel through the insulation, droppings accumulate, ground moisture rises and sagging batts fall to the dirt. Meanwhile, the air in the crawlspace moves upward into the house.
In the Pacific Northwest, moisture is the second half of the story. Damp conditions encourage mold, rot and carpenter ants, and make the space even more welcoming to pests.
Cleanout and inspection
We start by clearing debris and contaminated insulation, and by looking at the structure: floor joists, pipes, ducts, vents and the soil. Evidence of animals, moisture and wood damage is documented so you know exactly what we found.
Vapor barrier and moisture control
A heavy-duty ground vapor barrier covers the soil to limit moisture rising into the space. Along with vent repair and drainage recommendations, it brings humidity down and makes the crawlspace a poor environment for mold and pests.
Insulation and sealing
After cleaning, we reinsulate the underside of the floor and seal gaps around pipes and vents. Foundation vents are screened or repaired so animals cannot slip through. The result is a space that is easier to inspect and harder to invade.
What to watch for
Rodent damage
Tunnels in insulation, droppings and chewed ducts are common after long infestations.
Ground moisture
Bare soil releases vapor that damages wood and raises humidity.
Open vents
Broken screens and gaps in the foundation are the way in.
