REP Frequently Asked Questions

Q: Does REP test for radon?

A: No, REP believes this presents a potential conflict of interest, therefore, works with numerous state-certified third party testers. You can also purchase a testing system through Amazon here.

Q: How long will the radon mitigation take?

A: Generally, installations take less than a day. Homeowners do not need to be present during the installation, however, they are more than welcome to be there and our team will answer any questions.

Q: How much does it cost for a radon mitigation estimate?

A: Estimates are free of charge within 50 miles of Solon, IA.

Q: Is the warranty transferable?

A: Yes, the warranty remains with the system, not the individual that chooses to install it. All systems come with our standard 5 year warranty. Customers have the choice to extend this guarantee to 10 years at an additional cost.

Q: Will the price of the installation include a post test?

A: Yes. REP contracts a state-certified third party testing company post installation for verify radon levels have been reduced to the appropriate levels. A list of Iowa Department of Public Health (IDPH) licensed radon measurement professionals can be found on the IDPH Radon Program website by clicking here and selecting the second available link on the page.

Q: Do you accept credit cards?

A: Yes, an additional 4% convenience fee will be charged.

Q: What is the loud high-pitched noise coming from the base of my radon system?

A: It is likely due to a crack in the silicone that seals the base of the system. You can reseal this with 100% silicone or call us. If you choose to reseal it as the homeowner, your warranty will NOT be voided.

Q: Is it normal to hear a gurgling sound at the base of the system?

A: It is not uncommon to hear a gurgling sound after a heavy rain or large thaw. If the sound continues for more than a week, please call/email REP and we will schedule an appointment for service.

Q: My radon pipe goes into my sump and I need to replace the pump motor, how should I proceed?

A: An experienced individual (i.e. plumber) can cut the radon pipe to replace the sump and reconnect the radon pipe into the sump lid which will require resealing with 100% silicone.

Q: What do I do if my u-tube reading is even or at zero?

A: Call/email REP for instruction.

Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas.


If your first test has a result between 4 and 8 pCi/L, you have the choice of testing again. If results are needed quickly, you can re-test with a short-term (2-7 days) device.


Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings.
