Portland's Highland Rim clay stays saturated right through the spring, which is when most homeowners here first notice the smell coming up through the floor. Full encapsulation runs $4,000 to $15,000 and a vapor barrier alone starts around $2,500. Free inspection, written estimate handed to you on site.
What makes Portland crawl spaces damp
Portland's Highland Rim clay drains slowly and stays saturated through the spring, which is exactly when homeowners here start noticing the smell coming up through the floor. You cannot air-dry ground like that. Summer vents feed the space humidity, that moisture lands on the joists and the ductwork, and by the time you smell it upstairs it has been going on for years. Sealing it is the only thing that holds.
Our crawl space work in Portland
A Portland job usually means clearing out plastic that has broken into pieces, treating framing that has already started to grow, and then getting the space sealed and dried before another wet spring comes around.

Portland crawl space questions
What is the price range for crawl space work in Portland?
$4,000 to $15,000 for a full encapsulation, from around $2,500 for a vapor barrier only. Cleanout tends to be a bigger share of the work here, because the original plastic has usually broken up completely.
Is Portland too far north for you?
No. Portland is part of our regular Sumner County run, and the free inspection applies there the same as it does closer to the shop.
There is mold on my floor joists. Can that be treated?
Yes, and treating the framing is part of the job. But it comes back if the moisture source stays, so the sealing and the dehumidifier are what actually solve it rather than the treatment on its own.
Should I wait until spring to see how bad it gets?
We would rather look now. Water lines on the piers and rust on the duct straps tell us what the space does in March even if it looks dry in September, and you have the estimate in hand either way.
