Let’s take about a 1000 to 1500 square foot crawl space. You’re probably looking at about $5,000 to $15,000 just to encapsulate. We would consider encapsulation removing and replacing the vapor barrier, making sure it’s insulated, installing a dehumidifier and making sure it’s properly ventilated.
How much does it cost to vapor barrier a crawl space?

What is the difference between a vapor barrier and encapsulation?
The difference between a vapor barrier and encapsulation in a crawl space is thickness, flexibility, and a sealed interior.

Does crawl space encapsulation stop radon?
Radon moves up through the soil and into the crawl space air. Crawl space encapsulation can reduce radon levels and prevent moisture damage.. Radon is an invisible, odorless radioactive gas that comes from the decay of uranium in the soil.
Do you need a dehumidifier with a vapor barrier?
