"Steve is very professional, attentive to detail and offers great service. He was quick to respond to my request for a radon mitigation system installation, gave a fair estimate, and answered all my questions. The installation took one day and clean up was excellent. The system has reduced my basement radon level to 2.2.....it works! Highly recommend C&S!"

"The structural/electrical/plumbing inspector was fantastic. He spent over 4 hours going through every inch of the home, provided immediate in-person feedback showing significant issues, and followed up <48 hours later (on a holiday weekend) with a 133-page report with pictures, thermal scans, etc. On a lesser note, the radon inspector showed for a few minutes during the structural inspection and set-up measurements in the basement. The report was issued quickly but I found out later that the radon inspector had not taken into consideration the attached (inaccessible) crawlspace that made up 25% of the lower structure. I found out from a radon remediation contractor that the state code required the radon inspector to measure levels on the 1st floor above the crawlspace in cases where the substructure could not be accessed. Overall, the huge amount of time the structural inspector put into the property was worth the A rating. Just watch the radon inspection if you have a strange basement set-up like the house I am purchasing."

"Office communicated. Had a signed contract with pricing for the install. I was able to pay via credit card very easily over the computer. Installer was professional and cleanliness up after himself. Owner called to verify my satisfaction with the work. Post radon test was below the allowed amount of radon. Highly recommend this company."

"They first visited our home and after evaluating the situation, drew up a detailed plan and provided a written bid for performing the work. <br />The bid included a guarantee that their system would reduce the radon in our basement to an acceptable level. <br />After they received our signed contract they called and scheduled to do the work within one week. <br />They arrived promptly at the scheduled date and time. They completed the work in a professional manner in the estimated time allotted and took care to clean the work areas when they were done. <br />They provided a radon test kit to verify that the system worked as intended. <br />We have received the results from the follow-up test and we are very happy that radon levels have decreased to less than 1. <br /> <br /> <br />"

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"At first not so well. I had a passive system currently installed and I was hoping making it active would solve my radon issues; note my radon levels were off the charts at around 130 pCi/L. Mike and son showed up on time and performed the work quickly and efficiently. They needed access to my attic in which they added a fan to my passive system, did some sealing around my sump and added a manometer. Total time of around 1 hour. Unfortunately though running efficiently, this only brought my readings down to around 75 pCi/L. Cost of 1st install was $765 Mike and son came back out again and installed another suction point, including drilling and installing 4" pvc, another fan, and another manometer. Total time of around 1.5 to 2 hours. Again on time and done efficiently. Both times they cleaned up everything and were respectful of my house. Luckily this time it worked, bringing my levels down to around 1 pCi/L. Cost of 2nd install was $965."

FAQs for radon gas testing projects in Shrewsbury, PA

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
