I've been looking into local radon contractors lately, since our test showed levels a bit above the EPA action limit. It's a relief to find pros nearby who actually walk you through the whole mitigation process, from diagnostic testing to installing a system that vents soil gases safely above the roofline. They even help with post-installation follow-up testing to make sure it's working right.
