We are a Family owned business and have locally operated in south eastern PA for over 25 years. We don't sub-contract any of our work. We take pride in our work, and in doing so, have become experts in Radon Remediation.

"I contacted three different companies to obtain estimates. Only one, RTE, offered to come out and inspect the property and thoroughly explain what would be needed. There was no pressure to sign a contract. The other two companies had me answer questions about the house and then sent their estimates. I was impressed that the owner of the company himself came out to provide the estimate. Their expertise, customer service, and quality of work far exceeded my expectations. I just got back the results of the post-remediation testing and level was reduced to 1.2, I highly recommend this company. They serve a wide area of the Delaware Valley."

"Dave did our home inspection, felt he was thorough, pointed out a lot in the house with a lot of detail in the report. The deal didn't go through (not because of the inspection), and we didn't hesitate to call him for another inspection when we found another house. Same experience, would definitely use him again."

We provide same day picture filled reports and spend the time discussing the findings in it with you during and after the inspection. We are certified with ASHI (American Society of Home Inspectors) and fully insured.

"Ross Kennedy got stuck on the roof when he did my home inspection. He failed to report on major structural issues which cost me hundreds of thousands of dollars. Would not recommend."

Radon Detection and Reduction questions, answered by experts

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.
