Local conditions in South Saint Paul

Minnesota Department of Health guidance is that every home in the state should be tested for radon, and South Saint Paul is no exception. Dakota County falls in EPA Radon Zone 1, the highest-potential category. In a city of about six square miles, soil gas can collect in basements and lower levels, which is where we place the monitor. Radon tests are run under closed-house conditions, and the result is easiest to use in plain terms, including when mitigation is worth discussing.

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.
Do houses on the South Saint Paul bluffs need special inspection attention?
Yes, slope matters. Retaining walls, grading that directs water away from the foundation, cracks or stair-stepping in masonry, and doors or windows that stick because the structure has shifted are the signs worth noting. Drainage is usually the cause of trouble on a hillside. If we see signs of active movement, we recommend a structural engineer rather than guessing.
What is common in South Saint Paul homes?
Older housing stock means original panels, galvanized plumbing and clay sewer laterals — a scope is frequently worthwhile here.
