"Bob from SIS is a straight shooter, provides options, clear explanations and associated costs on the necessary steps to remediate the problem. Good communication, timely and professional. Pleasantly surprised with my experience with SIS and the contractor they recommended to do the work. Easy 5-star rating, not too common these days."

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

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.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
