Blackburn Foundation Repair Provides Premium Radon Testing Services
Radon Testing Is Key to Reducing Dangers at Home
Radon is an invisible, odorless gas that can build up indoors. The EPA identifies it as the second leading cause of lung cancer in the United States after smoking. Testing is the only way to know your home’s radon level, and neighboring homes can have very different results.
Testing your home is the first step toward understanding its radon level. Blackburn Foundation Repair offers professional radon testing in South Dakota and Wyoming. For our free charcoal test kit, we recommend a 3- to 4-day test period for best results, following the instructions included with the kit. Professional testing with a continuous radon monitor is a separate option. We’ll explain your results and whether additional testing or mitigation should be considered.
We encourage you to call us at 1 (800) 392-3389 today to get this test scheduled or to receive our free Structural Analysis along with an estimate for a Mitigation System if you have previously been made aware of high radon levels in your home.
The Three Steps of Radon Testing
- Radon testing is quite simple and starts by contacting Blackburn Foundation Repair so that we can take care of the work for you. First, we will schedule the setup of the Continuous Radon Monitor along with a followup meeting to chat about the results of the testing. Both meetings will be quite short.
- Second, we will send a specialist from Blackburn Foundation Repair to set the monitor up and to discuss how you can get the most accurate results.
- Third, our specialist will go over the test results with you after at least 48 hours of monitoring. You will be provided with a printout of the results, which will tell you whether radon levels in your home are high or low.
Radon Testing Results
The EPA recommends taking action when a home’s radon level is 4 pCi/L or higher. Because there is no known safe level of radon exposure, the EPA also recommends considering a fix for results between 2 and 4 pCi/L. If your test is elevated, we can help you understand the result and discuss next steps.
An elevated result is a reason to plan a solution, not to panic. Radon mitigation systems can reduce indoor levels, and a follow-up test confirms how well the system works in your home. Learn how radon mitigation works or contact Blackburn Foundation Repair to discuss your test result.
Professional Versus Do-It-Yourself Radon Testing
Our free charcoal test kit gives homeowners a convenient way to check their radon level. For best results, follow the included directions and leave the kit in place for 3 to 4 days. We can help you understand the result and decide whether another test or a mitigation evaluation makes sense.
Professional testing with a continuous radon monitor is another option, especially when you need a documented result for a home sale or want help with setup and interpreting the readings. Blackburn Foundation Repair can explain which testing option fits your situation.
Instead of wondering how safe your home is, find out the truth today using professional radon testing. Contact Blackburn Foundation Repair at 1 (800) 392-3389 to schedule a time to get your radon monitor set up and to go over your results.

Radon Testing FAQs
Can I tell whether my home has radon without a test?
No. Radon has no color, smell, or taste, so a properly performed test is the only way to measure the level in a home.
What is the difference between short-term and long-term testing?
Short-term tests provide a snapshot over several days. Long-term tests measure for more than 90 days and better reflect changes across seasons.
When should a home be retested?
Retesting is useful after remodeling, changes to heating or ventilation, foundation work, or installation of a mitigation system. Periodic testing can also confirm that levels remain low.
Where should a radon test be placed?
It should generally be placed in the lowest level that is regularly occupied or could become living space, following the device manufacturer’s instructions.
What happens if the result is 4.0 pCi/L or higher?
The EPA recommends taking action at or above 4.0 pCi/L. Learn about radon mitigation or request an evaluation.
