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."

Radon Detection and Reduction questions, answered by experts

Through air sampling devices and surface swabs in key areas of concern.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

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.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
