Radon Testing and Mitigation Referrals in Hilliard, Ohio

Hilliard is a northwest Columbus suburb in Franklin County, bordered by Dublin to the north and Upper Arlington to the east. Franklin County is EPA Radon Zone 1—the highest predicted indoor radon potential on the federal map. Predicted potential is not a reading for your address. Only a test tells you that.

Call (614) 363-6129 to get connected with a licensed Ohio radon professional for testing or mitigation in Hilliard (ZIP codes such as 43026).

Westerville Radon is a free referral service. We are not a licensed radon tester or mitigation contractor. When you call, we connect you with licensed Ohio radon professionals who can test or mitigate your home.

Franklin County radon context

Ohio Department of Health (ODH) data from licensed professionals shows that about 44.9% of Franklin County pre-mitigation tests exceeded the EPA action level of 4 pCi/L. ODH stresses that maps and county averages are educational. Every home should be tested. The EPA recommends fixing homes at 4 pCi/L or higher and says you may want to reduce levels between 2 and 4 pCi/L.

Hilliard neighborhoods that often call for testing

Hilliard’s housing ranges from walkable Old Hilliard to larger golf-course and subdivision homes—useful for knowing what a tester or mitigator may see, not for predicting your result.

• Old Hilliard. The city’s historic core anchors the Heritage Trail, Station Park, restaurants, and local events. Housing here is denser and more mixed in age. Basements, crawl spaces, and older foundations appear throughout; entry points for soil gas (sump pits, floor-wall joints, utility openings) are common in any era of home.
• Heritage Lakes and Fairway Commons. Established in the mid-1990s as a golf-oriented community of roughly 188 homes (Heritage Lakes plus Fairway Commons), with homes typically 2,700 square feet and up and an average around 3,600 square feet. Many properties include full or finished lower levels. Listings regularly note basements overlooking the course or stocked ponds.
• Hoffman Farms, Britton Farms, Lakewood, Scioto Run, Hayden Run Village, Weston Trail, and similar subdivisions add more late-20th- and early-21st-century single-family plans—ranches, two-stories, and finished basements near trails, parks, and The Well recreation campus.
• I-270 runs through the east side of Hilliard, so many addresses are a short drive from Dublin, Upper Arlington, and northwest Columbus job centers. Commute convenience does not change the geology under the house.

What we refer—and what we do not do

Westerville Radon is a referral site. We do not perform radon tests, and we do not install mitigation systems. Call (614) 363-6129 with your Hilliard address or neighborhood, whether you need testing or mitigation, and your preferred timing. We connect you with a licensed Ohio professional.

Background reading: our radon testing and radon mitigation pages. Typical Ohio residential mitigation costs are quoted by licensed contractors after they see the foundation—not by this website. Local providers have publicly described many systems in roughly the $1,400 to $2,500 range; your quote depends on the home.

Buyers, sellers, and routine retesting

If you are buying in Hilliard City Schools, put radon on the inspection checklist and call us for a licensed tester. Sellers who test before listing can address elevated results without a last-minute scramble. Long-term owners should note ODH’s guidance to retest single-family homes about every two years, or after renovations that change how the house breathes.

After mitigation, ask for a post-mitigation test. Keep records with your home file for future buyers.
