Highland Park / Oak Park radon expertise

## Helping First-Time Buyers

Many homes here sell to first-time buyers, and radon often comes up during the inspection. We test inside the contingency window and explain the result in plain terms, so you can negotiate with real numbers.

If the result is high, a standard sub-slab system with sump and crack sealing usually brings it down. We can often install before closing and run the post-mitigation test the lender or buyer wants to see.

## Common Issues in Mid-Century Homes

**Open sump pits.** Many basements have open or loosely covered sump pits tied to drain tile. We install airtight, gasketed lids.

**Unsealed floor cracks.** Mid-century slabs often have cracks and a gap at the floor-wall joint. We seal them as part of every install.

**Simple layouts.** Many homes here have a single basement slab, which often means one suction point does the job.
