How Much Does Radon Mitigation Cost in Maine? (2025 Guide)

# How Much Does Radon Mitigation Cost in Maine? If you've received a radon test result above 4 pCi/L — the EPA action level — you're probably wondering what it costs to fix the problem. Here's a straightforward guide to radon mitigation pricing in Maine. ## Typical Cost Range Most Maine homes are mitigated for **$800 to $1,600**. The majority of single-family homes with a standard poured concrete or block basement fall between $900 and $1,400 installed. ### What Drives the Price Up or Down **Foundation type** is the biggest variable. Poured concrete slabs and standard basement floors are the easiest (and least expensive) to work with. Crawlspaces, multiple foundation sections, or combined slab-plus-crawlspace homes take more materials and labor. **System complexity** matters too. A simple sub-slab depressurization system with one suction point and a single fan is the norm. Some homes require multiple suction points, longer pipe runs, or specialized fans — all of which add to the cost. **Home size** has a moderate effect. A 1,200 sq ft Cape is straightforward. A 2,800 sq ft colonial with an attached garage and a partial crawlspace is more involved. ## What's Included in a Professional Mitigation A proper mitigation installation in Maine includes: - **Site assessment** — the technician evaluates your foundation, measures sub-slab conditions, and designs the right system for your home - **PVC pipe installation** — typically 3" or 4" Schedule 40 pipe routed through the basement wall or up through the interior - **Radon fan** — a dedicated continuous fan creates negative pressure beneath your slab, drawing radon out before it enters your home - **Electrical connection** — the fan is hardwired or plugged into a dedicated circuit - **System label and U-tube manometer** — so you can visually confirm the system is working - **Post-installation walkthrough** — the technician explains what was installed and what to watch for ## Should You Get Multiple Quotes? Yes — but be careful what you're comparing. The cheapest quote isn't always the best value. Ask each company: - Are they NRPP certified? - Is the fan included, or is it extra? - What happens if the system doesn't reduce levels below 4 pCi/L? - Is there a warranty on the installation? At Central Maine Radon & Water Mitigation, our quotes are itemized and firm — the price we quote is the price you pay. ## Radon in Water: Separate Cost If your home has radon in well water (separate from radon in air), water treatment is a different system. Aeration units for well water radon typically run **$2,500–$4,500 installed**, depending on flow rate and water conditions. We handle both air and water radon. ## The Bottom Line For most Maine homes, professional radon mitigation costs less than a car payment and protects your family indefinitely. The system runs 24/7, requires minimal maintenance, and can add value to your home when it's time to sell. If you've tested above 4 pCi/L, don't wait.
