Asheville Radon Mitigation helps homeowners across Asheville and Buncombe County with four core services: radon mitigation system installation, crawlspace radon mitigation, radon testing and retesting, and radon fan repair with system checkups. Most homes need exactly one of these — this page helps you figure out which one, and each service links to a full page explaining the work.
You don’t need to know the right technical term before calling. But if you want to read ahead, the match usually works like this: an elevated test in a home with a basement or slab points to a standard mitigation system. An elevated test in a home over a vented crawlspace — extremely common in Western North Carolina — points to crawlspace mitigation. No test yet, or a deal that needs a clean result? That’s testing. And if your home already has a system with a pipe and a little u-shaped gauge on it, but the fluid in the gauge sits level, that’s fan repair.
Plenty of Asheville homes need a combination — a walk-out basement with a crawlspace wing is one of the most common hillside layouts here, and it usually takes suction points in both zones tied to one fan. That’s a scoping detail we work out on the quote call, not something you need to decide.
The standard fix for basements and slab-on-grade homes: a sealed suction point in the slab, PVC piping, and an inline fan that vents soil gas above the roofline. Most installs are a single day.
Sub-membrane depressurization: a heavy sealed liner over the crawlspace soil with suction drawing soil gas from beneath it. Built for the vented crawlspaces under WNC bungalows and mountain homes.
Short-term tests for real-estate due diligence, post-mitigation verification tests, and periodic retests after renovations or basement finishing.
Diagnosis and replacement of failed or failing radon fans, plus checkups on systems that came with the house and haven’t been looked at since.
Whatever the service turns out to be, the first step is identical: call or send the quote form with whatever you know — a test number, “the gauge looks level,” or “we haven’t tested but we’re closing in three weeks.” We ask a few questions about the foundation and the house, and most of the time that conversation produces a scoped quote. When a layout genuinely needs a look first, we say so on that call instead of guessing.
Thirty seconds. We follow up by phone — usually with a clear scope from that one call.
You don’t need to understand the report. The number is enough — for example, “inspection said 6.8” tells us almost everything we need to start.
Call with whatever you know — a number, a symptom, or a closing date — and we’ll match the service to the house on that call.
