York Township isn't York. It's a separate township that starts right at the city's south edge and runs about 25 square miles from there. It was formed in 1753, and it's still growing. The Census estimate went from about 29,700 residents in 2020 to about 31,500 in 2025. Most of it uses a York mailing address, so people mix the two up all the time. For me it's home turf either way. It's the same work I do for radon mitigation in York PA, just with more variety in the houses.
What's Under York Township
York Township covers a lot of ground, and the ground changes across it. The north end sits near the limestone valley by the city, and the south end climbs into the harder hill rock toward Dallastown. That's one reason neighbors here test so differently. More on York County geology and radon.
Which York Township House Do You Have?
The township's 2025 comprehensive plan, shared with Spring Garden, describes York Township as having more newer subdivision growth, rural land and preserved farmland than its neighbor. That range is exactly why I won't quote a system over the phone. Here's roughly how the plan changes by house type.
A mid-century house around Spry or off South Queen Street. Full basement, often partly finished, sometimes a sump. This is usually a single suction point and a clean pipe run, if the basement layout cooperates.
A 1980s or 1990s subdivision home. Bigger basement footprint, poured walls, maybe a finished rec room and an attached garage. A big slab can need a second suction point to pull the whole floor. The garage is often the best place to run the pipe up and out of sight.
A newer build. New doesn't mean low. Pennsylvania DEP recommends testing after you move in, even if the builder added radon-resistant features. If there's a capped pipe in the basement floor with no fan, it may just need a fan added to the existing pipe.
An older farmhouse toward the township's rural edges. Stone or mixed foundations, a cellar under the original house, and additions that came later on their own footings. These take the most diagnosing, because air under one section may not move under the next.
Not sure which one yours is? My foundation guide shows you how to tell in five minutes with a flashlight.
The Numbers Around York Township
No dataset lines up with the township boundary, so here's what the ZIP codes that cover it show.
- 17402: Pennsylvania DEP's public records show 5,119 of 8,558 basement tests at or above 4 pCi/L, about 60 percent. York County's 2024 Hazard Mitigation Plan reported an average of 11.8 pCi/L across 17402 basement readings from 1990 through 2022.
- 17403: The same county report put the 17403 average at 12.4 pCi/L.
Both ZIP codes stretch past the township into the city and neighboring townships. Both averages come from closed-house tests, which tend to run higher than normal living conditions. So they tell you radon is common around here. They don't tell you what your house reads. For that you need a test, and my radon testing is typically around $165.
If You Live in Your Basement, It Matters More
Radon exposure is about how much is in the air and how long you're breathing it. A York Township basement that's a family room, a home office, a guest bedroom or a gym gets a lot more hours than a storage basement. If that's how you use yours, that's the level I'd want tested, and it's the level I'd design the system around.
A finished basement doesn't stop me from installing a system. It changes where I can put the suction point and how the pipe gets out. I'll work around your finished space instead of through it wherever I can.
The Job, Start to Finish
I walk the house and check how air moves under the slab. You get one written, all-inclusive price. My crew and I install the pipe and fan, seal cracks and openings, including the sump if it's open, and then I retest the house after install. The retest is part of the price.
York Township Questions
My house is big. Will one fan handle it?
Often yes. A single fan can run more than one suction point if the pipe is laid out right. What matters is whether the whole slab gets pulled, and I check that during the install, not after.
Is York Township the same as the City of York for your pricing and scheduling?
Yes. Same free estimate, same written quote, same hours: 7:30am to 7:30pm weekdays and 7:30am to 2:00pm Saturdays.
I'm out near the farmland with a cellar and a newer addition. Can that be done?
Usually, but it's rarely a one-point job. The cellar and the addition often need separate treatment. I'll tell you how many suction points I think it needs and why before you agree to anything.
I just bought a house here and the seller's system is already in. How do I know it's working?
Look at the gauge on the pipe. If the liquid levels are even, the fan likely isn't pulling. Even if the gauge looks fine, a fresh test is the real answer. If the system needs work, I service systems I didn't install.
