Radon Testing in Saint Paul

Radon Testing in Saint Paul, Ramsey County, by Closer Look Inspectors. Saint Paul is the capital city, a dense stock of Victorian, Craftsman and early-1900s homes wrapped around the river bluffs and the lakes.

Radon testing places an EPA-protocol continuous monitor on a home's lowest livable level to measure radon gas — and it matters across Minnesota, where more than two in five homes test above the action level.

Local housing

Homes in Saint Paul.

Saint Paul housing runs to Victorian, Craftsman and early-1900s homes with pockets of newer infill, across the river bluffs, the lakes neighborhoods, and the dense historic districts, on river-bluff and lake-adjacent clay sites — and that mix shapes what a radon testing here needs to find.

Local conditions in Saint Paul

Radon is a good example of why Saint Paul basements deserve a closer look. Ramsey County sits in EPA Radon Zone 1, and the Minnesota Department of Health recommends testing every Minnesota home, whether it is a stone-foundation Victorian or a newer townhome. Our testing is run under closed-house conditions, typically in the lowest lived-in level, and gives you a number to act on. If a result comes back elevated, it helps to know what mitigation generally involves, so the question of the basement gets a factual answer instead of a guess.

Questions

Common questions.

Is radon really a concern in Minnesota?
Yes. The Minnesota Department of Health reports that more than two in five Minnesota homes have radon levels that pose a significant health risk, and finished basements are where it concentrates.
How long does the test run?
A 48-hour minimum under closed-house conditions; the result is delivered with your inspection report.
What are the differences between homes in Highland Park, Mac-Groveland and Como?
Macalester-Groveland is mostly pre-1939 housing that grew after streetcars were extended to the area, with Tangletown's curvy streets as a distinct area. Highland Park sits on the river at the southwest corner of the city, with the former Ford plant site now redeveloped. Como Park is centered on Como Lake. All three call for checking sewer laterals, basements and roofs, but the priorities shift: masonry and porches in the older blocks, drainage near the lake and river.
Do you inspect Saint Paul's older historic homes?
Yes — the capital's pre-war stock is our home turf. We read original panels, knob-and-tube remnants, aging boilers and the structural quirks of century-old construction with an experienced eye.
