I have a small crawl space (16' x 12') that needs a vapor barrier put in. When I bought the house about a year ago, radon tested at 4.1, so I'm hoping that sealing this area will decrease that. Do you also do radon testing and/or remediation? I didn't see it on the website. I prefer contact via email. Thanks.
