Local radon know-how, house by house across York County

Dave Kessler runs Radon Mitigation of York out of the county he grew up in, and he's spent his career crawling through the crawlspaces and basements of the same neighborhoods he knows by name — Downtown York rowhomes near the Central Market House, the older stone-and-brick housing stock around West York and North York, and the newer builds out toward Spring Garden Township and Devers. York County sits on limestone and fractured bedrock terrain that's notorious for allowing soil gas to move freely into basements, and that geology doesn't care whether a house was built in 1920 or 2015. Dave's job is to read each house's foundation, soil, and airflow patterns and design a mitigation system that actually matches what's happening underneath it, not a one-size-fits-all pipe stuck in a slab.

What sets this business apart is that Dave still does the site visits himself. He'll walk your basement, check your foundation type — whether it's a sump crock, a slab, or a mix common in older Pinehurst and East York homes — and explain in plain language why radon levels tend to spike here once winter sets in and homes get sealed up tight against the cold, or why humid summer soil moisture can change how a system performs. He's tested and mitigated houses within sight of the York Fairgrounds, near Codorus State Park, and in the tighter lots around the Strand-Capitol Performing Arts Center downtown, so he's seen how radon behaves differently block to block, not just county to county.

Radon Mitigation of York is set up to give homeowners a straightforward experience: a real inspection, a real explanation of what the numbers mean, and a system installed to work with your specific house, not against it. Dave keeps his crew small and his schedule realistic, which means he's not juggling five subcontractors and a call center — you're dealing with the person who's actually going to be on your roof or in your basement running pipe.

I grew up in West York and spent a good chunk of my career doing residential HVAC and foundation work around York County before I got into radon mitigation full-time. What pulled me into this specifically was seeing how many older homes in Downtown York, Spring Garden Township, and North York still had unfinished stone or rubble foundations that basically let soil gas walk right into the basement. That's common housing stock here — a lot of it pre-dates any real thinking about radon, and the fieldstone and limestone geology under York County makes elevated readings pretty routine once you test for it. I started this business to do one thing well: design a mitigation system that actually matches the house instead of a cookie-cutter pipe-and-fan setup. Every home from Devers to Pinehurst to East York has its own quirks — sump pits, crawlspaces, slab additions tacked onto older structures — and I walk every job myself before quoting so the customer knows exactly what's getting installed and why. Our cold winters mean homes get sealed up tight for months, which is exactly when radon concentrations climb, so I try to get systems in before the weather turns. I'm in and around York County jobs most weeks, from Codorus State Park out to the neighborhoods near the Fairgrounds, and I still do the estimates myself rather than handing that off. We're open Monday through Friday 8am–6pm and Saturdays 9am–2pm, and I give straightforward, upfront quotes with a job you can inspect at every stage.
