Radon Testing built for Hilltop homes
Hilltop is the smallest incorporated city in our service area — barely 0.1 square mile and roughly 750 residents — completely surrounded by Columbia Heights. Hilltop's housing inventory is unusual: it's almost entirely manufactured-home parks and a small handful of stick-built single-family homes from the 1950s. Manufactured home inspections are a different discipline than site-built — we inspect the marriage line, tie-downs, HUD tags, axle/wheel removal status, skirting and crawl-space ventilation, and the hookups for water, sewer, and gas. Common findings on Hilltop manufactured stock: original 1970s-1980s units with deteriorated subfloor at bathroom and kitchen wet zones, original aluminum wiring (used commonly in older HUD-code homes), mismatched insulation, ductwork hung in the belly, and roofs near or past lifespan. We do FHA-, VA-, and conventional-loan-compliant inspections on manufactured units. Schools are Columbia Heights ISD 13. Drive time from Blaine: 18 minutes. Hilltop is small but inspection-heavy — most lender programs require a third-party inspector.
That local context shapes how we approach radon testing here. All of Anoka County sits in EPA Radon Zone 1, where roughly 4 in 10 basements test above the 4.0 pCi/L action level. Every Hilltop inspection includes a digital report in 24 hours and a phone walkthrough. A common related finding in Hilltop is radon above action level — we check for it carefully.
