What if high levels of Radon are found and how much does radon mitigation cost?
Reducing radon levels within your home is actually quite simple; however it should be performed by a radon mitigation company that specializes in reducing radon levels. There are various ways to mitigate the problem: one way is to prevent radon from entering the home, another is to reduce the radon level once it is there. Generally, the radon mitigation process includes installing a small, quiet fan that creates suction under a thick, sealed, plastic barrier in the crawlspace and vents the radon gasses out from under the home. Homes with basements or built on a concrete slab are more susceptible to high radon levels. In this case all of the cracks and crevices are sealed. Then a hole is put in the slab to install the small fan and create sub-slab suction. The average Radon mitigation cost in Portland, Oregon, or Vancouver, Washington is between $800 to $2,500 with an average of $1,200. Generally, the fan system requires little to no maintenance once installed.
