New-Construction Radon in York, PA
A white pipe in the garage or a roof jack from the builder is a start. It is not a living system until a fan and a test say so.
What builders leave behind
Newer streets in Dover Township, East York, and toward Shrewsbury often have a passive radon stack from the pour: a pipe through the slab or sump, up through the house, and out the roof. That is radon-resistant construction — a path for soil gas, not an active system.
A passive stack can still leave the house above 4 pCi/L. Activating it means adding a fan, confirming suction, and testing. Painting over the roof jack does not count.
Activate vs. design from scratch
If the pipe is already there and sealed to the slab, we treat it as a fan install on an existing run. If the house was built with no pipe, it is a standard sub-slab job.
Test first either way (radon testing). A new house in Zone 1 is not automatically “already handled.”
Next step: the mitigation process, the services list, or the quote form.
Frequently Asked Questions
Questions we hear on York County jobs.
Did the builder already mitigate my York County house?
Usually they left a passive pipe. That is not the same as an active system with a fan and a passing post-test. We will look at what is there and say which it is.
What is a passive radon stack?
A pipe through the slab or sump, up through the house, and out the roof — radon-resistant construction. Newer streets in Dover Township, East York, and toward Shrewsbury often have one from the pour. It is a path for soil gas, not a living system until a fan and a test say so.
Should I still test a new house in Zone 1?
Yes. A new house in York County is not automatically “already handled.” A passive stack can still leave the house above 4 pCi/L. Test first either way — radon testing — then decide whether to activate the pipe.
Can you put a fan on the pipe the builder left?
If the pipe is already there and sealed to the slab, we treat it as a fan install on an existing run: add the fan, confirm suction, then test. Painting over the roof jack does not count.
What if the house was built with no radon pipe at all?
Then it is a standard sub-slab job — suction, PVC, fan, exhaust — not an activation. The process is still test, diagnose, install, retest on the mitigation page.
