Manchester, New Hampshire sits atop granite bedrock, a geology that naturally emits radon gas. The U.S. Environmental Protection Agency classifies all of New Hampshire as Zone 1, meaning the average indoor radon level is predicted to exceed the action level of 4.0 pCi/L. According to the New Hampshire Department of Environmental Services, nearly 40% of homes tested in Hillsborough County (which includes Manchester) show elevated radon levels. With a population exceeding 115,000, Manchester is the largest city in the state and has a strong real estate market. Home sales, particularly in neighborhoods like North End, West Side, and the downtown area near Elm Street, routinely require radon testing as part of buyer inspections. The growing awareness of radon’s link to lung cancer has pushed more homeowners and landlords to seek testing independently. Consequently, the demand for certified radon measurement services is steady and increasing, especially in older multi-family homes and new construction alike.
New Hampshire requires radon measurement professionals to hold a valid certification. The state recognizes two main certifying bodies: the National Radon Proficiency Program (NRPP) and the National Radon Safety Board (NRSB). Additionally, the New Hampshire Radon Program (part of NHDES) offers a state-specific certification that aligns with NRPP standards. You must complete an approved radon measurement course (typically 16-24 hours) and pass a proctored exam. Once certified, you must renew annually by submitting continuing education credits. Beyond certification, you need a general business license from the City of Manchester’s Clerk’s Office. Liability insurance is highly recommended; many real estate agents require proof of insurance before allowing testers on client properties. NHDES also mandates that radon testing devices be calibrated annually per manufacturer instructions. Finally, familiarize yourself with New Hampshire RSA 125-I, which governs radon measurement and mitigation licensing, including record-keeping requirements and report formats.

Use posts to announce seasonal testing specials (winter is high season due to closed windows). Encourage clients to leave Google reviews; respond to every review professionally. Upload your test reports as PDFs in the “Products” or “Services” tab. Also add Q&A: “Do you test for radon in Manchester condos?” – answer with specific building types common in the city.
