Radon Inspection
Professional Radon Testing
Radon is a naturally occurring radioactive gas that can enter homes and buildings from the ground below. Because it has no color, smell, or taste, elevated radon levels can go unnoticed without testing.
MoldTec LLC provides professional radon testing for homes, businesses, property owners, and real estate transactionsto help determine the radon levels inside a property.
Get clear, independent results so you can make an informed decision about what to do next.
What Is Radon?
Radon forms naturally from the breakdown of uranium in soil, rock, and groundwater.
As radon moves through the ground, it can enter a building through openings where the structure meets the soil, including:
- Foundation cracks
- Basement floors and walls
- Crawl spaces
- Construction joints
- Gaps around pipes and utilities
- Sump areas
- Other foundation openings
Radon can be present in new or older properties, and neighboring homes can have very different radon levels.
The only way to determine the level inside a particular property is to test it..
Know What’s in the Air You Breathe
Radon can’t be seen, smelled, or tasted. Professional radon testing can help you understand the radon levels in your home or property and determine whether further action may be needed.
Common Signs That Shouldn't Be Ignored
Who Should Consider Radon Testing?
Radon testing may be appropriate if you:
- Own a home that has never been tested
- Are buying or selling a property
- Have recently moved into a home
- Have completed major renovations
- Have changed how a basement or lower level is used
- Have an existing radon mitigation system
- Want to verify previous radon results
- Own or manage a residential or commercial property
Even if another property nearby tested low, that doesn't necessarily indicate what the radon level will be in your building.

Why Is Radon Testing Important?
Long-term exposure to elevated radon levels can increase the risk of lung cancer.
According to the U.S. Environmental Protection Agency, radon is the second-leading cause of lung cancer in the United Statesand the leading cause among people who do not smoke.
Because radon cannot be detected through sight, smell, or taste, professional testing provides measurable information about the conditions inside your property..
Our Radon Testing Process
Stage 1: Pre-Test Preparation & Setup
Step one
We inspect your property to determine optimal radon testing locations and ensures proper testing conditions. Professional radon detection equipment is strategically placed in the lowest occupied levels of your building according to EPA protocols.
Stage 2: Testing & Monitoring
Step two
Radon detectors remain in place for the required testing period (typically 48-72 hours for short-term testing) to capture accurate radon level measurements. Testing conditions are monitored to ensure reliable results.
Stage 3: Results Review & Mitigation Planning
Step three
The inspector retrieves testing equipment and analyzes radon level results. The MoldTec team explains findings in detail, compares levels to EPA action guidelines, and provides specific recommendations for radon mitigation when levels exceed safe limits. Results are immediate and emailed to you.
FAQs
How do I know if my home has radon?
You cannot see, smell, or taste radon. The only way to know the radon level inside your home is through testing.
Do all homes need radon testing?
Radon can be found in both new and older homes. Testing is especially worth considering if your property has never been tested, you're buying a home, you've made significant renovations, or it has been a long time since the last test.
Can my home have radon if my neighbor's home doesn't?
Yes. Radon levels can vary from one property to another, even between neighboring homes. A nearby test result cannot determine the radon level inside your property.
Where is a radon test placed in a home?
Radon testing equipment is typically placed in the lowest level of the home that is regularly used or could be occupied. The appropriate location depends on the layout and conditions of the property.
How long does professional radon testing take?
The testing period depends on the method being used. Short-term radon testing commonly takes at least 48 hours, while other testing methods may monitor conditions for longer periods.
Should I test for radon when buying a home?
Radon testing can provide valuable information during a real estate transaction. It allows buyers to understand the property's measured radon level before completing the purchase.
What radon level is considered high?
The EPA recommends taking action when radon levels are 4 picocuries per liter (pCi/L) or higher. The EPA also recommends considering measures to reduce radon when levels are between 2 and 4 pCi/L.
What happens if my radon test comes back high?
If elevated radon is detected, a qualified radon mitigation professional can evaluate the property and recommend a system designed to reduce radon levels. MoldTec can help you understand your test results and the appropriate next steps.
Can radon be reduced in a home?
Yes. Radon mitigation systems can significantly reduce radon levels in many homes and buildings. Follow-up testing can then be used to determine whether the system is working effectively.
Should I retest after installing a radon mitigation system?
Yes. Post-mitigation testing helps confirm that the system has reduced radon levels. Periodic testing afterward can also help monitor conditions over time.
Does MoldTec provide independent radon testing?
Yes. MoldTec LLC provides professional radon testing and objective results so homeowners, property owners, buyers, and businesses can better understand the conditions inside their property.
