Testing certifications
The entries below are registered in York and dated 1 September 2026. Every one of them belongs to a named individual rather than to the business, which is worth knowing when you ask whose number covers your job.
| Cert number | Held by |
|---|---|
| 1631 | HOMECHEK, INC. |
| 1630 | JOHNSON, STEVEN |
| 8438 | HODGES, MATT |
| 8760 | KRUSZON, TATE |
| 8699 | MUROG, ALEX |
| 9130 | WILSON, NICHOLAS |
Six testers, no mitigators
Firm number 1631 plus five individuals appear in the testing register: Steven Johnson, Matt Hodges, Tate Kruszon, Alex Murog and Nicholas Wilson. Neither the firm nor any of those individuals appears in the mitigation register.
That is a clean division of labour rather than a limitation. Homechek measures, a mitigation firm installs, and the post-mitigation test that confirms the system worked comes from somebody with no stake in the installation.

Why an independent tester is worth the extra call
Across York County installations with a reading before and after, levels fell by 92 percent on average and 97 percent of houses finished below the action level. Those figures exist because somebody measured afterwards.
When the company that installed the system also runs the test that grades it, the number is still probably right, but nobody independent has checked. Using a testing-only firm for the measurement removes that question entirely, and at 150 to 300 dollars for a professional test it is the cheapest piece of evidence in the whole process.
How that compares
Of the 14 testing certifications held by the eight firms in this guide, 6 belong to this one, or 43 percent, and none of its certifications is for mitigation. Only 4 of the eight appear in the testing register at all.
Verify it before you book

Common questions about Homechek
Is Homechek certified for radon testing?
Yes. The September 2026 DEP register lists six testing certifications, including 1631 for Homechek Inc and five individual certifications. That is the largest testing presence of any firm in this guide.
Does Homechek install mitigation systems?
No. Neither the firm nor any of its certified individuals appears in the DEP mitigation register. Call them for the measurement, then a certified mitigator for the system.
Are they based in York?
Yes, on Eastern Boulevard in York, PA 17402. They are one of two firms in this guide with a York city address.
