Certified for both, which is convenient and worth a question
Seven certifications across the two registers means this firm can measure the problem and fix it. For a homeowner that is one phone call instead of two, and for a property sale it removes a scheduling dependency.
It also puts the same company on both sides of the result. The post-mitigation test is the only evidence that the system worked, and an independent tester is the stronger arrangement. Ask who signs off on that measurement before you book, and treat the answer as a preference rather than a dealbreaker.

Every review is a five star rating
All 97 Google reviews recorded on 21 September 2026 were five stars, which is unusual at that volume. Reviewers mention fan installation and scheduling speed most often.
A perfect record at 97 reviews says the common cases go well. It says less about the awkward ones, because customers with an awkward house are a small share of any review set. The scope on your quote remains the better guide to whether the company has understood your particular building.
The two DEP numbers on the firm's own site
Precision Inspections and Radon Solutions calls itself a fully licensed and insured home inspection and radon service company. Its site lists ASHI and InterNACHI certification and quotes the DEP numbers 2404 and 3105.
In the September 2026 register, 2404 is the mitigation certification of Jeremy Ling and 3105 is the firm's testing certification. The firm's own mitigation number is 3355. A quote should say which of these covers the work on your house. The site describes installed systems in apartment complexes, schools and commercial buildings. Read on 4 November 2026.

Common questions about Precision Inspections & Radon Solutions
Is Precision Inspections and Radon Solutions DEP certified?
Precision Inspections and Radon Solutions is DEP certified for both testing and mitigation. The September 2026 register lists three mitigation certifications, including 3355 for the firm, and four testing certifications, including 3105 for the firm.
How far is Mechanicsburg from York?
Roughly 35 minutes by road. Distance affects how quickly a job gets scheduled rather than whether it is taken, and the York County cost record shows no price premium for firms based outside the county.
Should the same firm test and mitigate?
It is legitimate and common, and an independent post-mitigation test is still the stronger arrangement because it separates the party doing the work from the party confirming it worked. Ask who performs and pays for that test.
