62% of Millcreek homes were built before 1980 (Source: U.S. Census ACS). For radon, older homes raise a few specific questions:
- Foundation walls. Most valley basements are poured concrete, but if yours has hollow concrete-block walls, ask the contractor whether block-wall suction is needed. EPA notes radon can move through block cores (Source: EPA). Block-wall suction.
- Old floor drains and cracks are common entry points. Sealing them is part of most installs, but EPA says sealing alone isn't a fix (Source: EPA).
- Basement remodels. If you're finishing an older basement, test first. EPA says radon-resistant measures can be added cheaply during a renovation, and you should test again after major work (Source: EPA).
Renting in Millcreek?
With about 39% of Millcreek homes renter-occupied (Source: U.S. Census ACS), a lot of people living over a basement don't own it.
- Tenants: a Utah DEQ kit costs about $11 (Source: Utah DEQ). You can test your unit and share the result with your landlord. Fixing it is the owner's decision and cost.
- Landlords: a passing post-mitigation test and a working manometer are easy to document, and they're useful when you sell. Cost to fix.
We aren't giving legal advice about landlord-tenant obligations; for that, check with a Utah attorney.
