Flint Township is the west side's postwar boom preserved in brick and block. Tract ranches and split-levels from the decades when this county was building as fast as it could. Fast building meant consistent building: block basement walls, sump crocks, slab floors poured over clay. The Census numbers back that up: the median township home was built in 1971, and about seven in ten went up between 1950 and 1989, from the older streets near the city line out to the subdivisions around Genesee Valley Center. Consistent building means consistent radon behavior, and consistent radon behavior means we can usually tell you what your install looks like before we've seen anything but the address and a photo.
The block-wall chimney effect, one more time
It comes up on every page about this county's housing because it decides half the jobs: hollow concrete block walls conduct soil gas upward through their cores like a chimney, releasing it through the open top course and every gap in the mortar. Township tract homes have block walls almost universally. The fix folds into the standard system, top-course sealing plus sub-slab or drain-tile suction, and it's the difference between a system that hits 1-point-something and one that limps in just under 4.
Split-levels, handled
The township's split-levels deserve a mention because test kits mislead in them: a kit on the mid level can read moderate while the lowest level, where the rec room and the kids' TV setup usually are, runs double. Testing belongs on the lowest lived-in level, and mitigation design in a split treats the stacked slabs as the single connected system they are. If your split-level tested “probably fine,” it's worth knowing where the kit sat.
Frequently asked
How fast can you get to a Flint Township job?
Township jobs are as close to the middle of our map as it gets. Quotes from photos same-day, installs typically scheduled within days, and the whole job done in one visit.
Our 1960s ranch has the original sump. Reuse it or start fresh?
Usually reuse. An original crock connected to drain tile is a ready-made suction network for the entire footprint. We seal it with an airtight lid, tie in the pipe, and your sump pump keeps doing its day job underneath. It's the most cost-effective system this housing stock offers.
