SHOULD I BE CONCERNED ABOUT RADON?
Radon is the number one cause of lung cancer among non smokers, and is found at unhealthy concentrations in one in fifteen houses in the US according to the EPA. Radon is odorless, and colorless. The only way to know if radon levels in your home are unsafe is to test. Long term tests[90+days] are affordable, and available online or at local hardware stores. Contact us for a 48 hr short term test.
WHAT IF MY NEIGHBOR DOES NOT HAVE RADON? 
Radon is very site specific. You can not rely on a neighbor's radon test as an indicator for another building. The primary factor affecting radon concentrations is whether there is a natural radon source beneath your home. It is exceedingly difficult to seal out radon as it can pass through most materials and microscopic cracks in the foundation. Instead, mitigation efforts redirect radon using a fan or vacuum to create a pressure differential; venting radon outside the home.
SHORT-TERM or LONG-TERM TESTING? 
The EPA defines any test longer than 90 days as a long term test. Long term tests are inexpensive and available online or at local hardware stores. Our short term tests provide hourly concentration levels throughout the test period in addition to basic weather condition records and can detect potential tampering. Short term tests are generally used during real estate transactions, or to verify the results of a long term test.

WHEN CAN I SCHEDULE A RADON TEST?
We do our utmost to accommodate same day requests if possible. Generally a few hours advance notice is all we need to set up a test; however windows must be closed for 12 hr before the start of the test, so in any case where we cant verify 12 hours of closed home conditions before we arrive, the test will be set on a 12 hr delay to allow radon levels in the home to normalize before the official 48 hr test period begins as per the EPA's radon testing for real estate transaction protocols.
CAN I STAY IN THE HOME DURING THE RADON TEST?
Yes. Windows must be closed for 12 hr prior to and for the duration of the 48 hr test period; doors can be used for normal entry/exit, but should not be left open. Conventional AC and Heating systems should be used as normal. Besides those requirements, radon testing is unobtrusive.

WHAT IS IN A RADON REPORT?
In addition to the average radon exposure level our reports also provide hourly data points on the radon concentration levels in the home as well as weather conditions throughout the test including temperature, humidity, and barometric pressure. Our machines also include motion sensors which combined with weather data can help to detect evidence of potential test tampering.
HOW & WHEN DO I PAY FOR MY RADON TESTING?
In the case that we are working with a home inspector we have an existing relationship with, we can add our service to the primary home inspection invoice. When working for customers directly, we prefer to be paid by check either during the test set up, or when collecting the meter approximately 48 hr later. We can also receive checks by mail. An invoice will be generated and sent via email as soon as we add the test to our schedule.
HOW FAR WILL YOU TRAVEL?
We are based in Lake Oswego, Oregon; but we serve a radius of communities in the greater Portland area. We do charge a distance fee for drives over 25 mi.
IS RADON TESTING RELIABLE?
Our machines are state of the art, and annually calibrated. Our technicians are trained, professional, and prepared to answer any questions about radon testing. We strive to ensure every screening we perform adheres fully to the EPA's Radon Testing for Real Estate transactions protocols.
