Thor Wiebe Home Inspections provides Radon Testing, Radon Mitigation, Home Inspections, and Air Quality Testing throughout Southwest Minnesota. Every service is approached with accuracy and clear communication, giving you understanding of where your home stands and peace of mind.

Radon is a naturally occurring radioactive gas that can be present in any home, regardless of age or location. Because it is colorless and odorless, testing is the only way to know if radon levels are elevated.
Thor provides professional radon testing using approved methods that follow EPA and Minnesota Department of Health guidelines. Tests are conducted carefully to ensure accurate, reliable results you can trust.
A written report is provided with your results, along with recommendations if radon reduction is needed.

If radon testing shows elevated levels, mitigation is the proven way to reduce radon gas inside the home.Thor designs and installs custom radon reduction systems based on the structure of the home and the results of the radon test. Each system is tailored to the home—never a one-size-fits-all approach—and is built to operate efficiently and reliably.
All radon mitigation systems include a 5-year warranty, providing long-term peace of mind and confidence in the system’s performance.

A home inspection provides a clear, objective look at the condition of a home at the time of the inspection. It’s designed to help buyers, sellers, and homeowners understand how the home’s major systems and components are functioning—and where issues may exist.
Thor provides thorough, unbiased home inspections with an emphasis on accuracy, clear explanations, and practical insight. Findings are explained in plain language so you understand what matters, what may need attention, and what can simply be monitored over time.
Each inspection concludes with a detailed digital report, including photos and written observations, delivered promptly after the inspection. Thor is also available to answer follow-up questions so you can move forward with clarity and confidence.

Indoor air quality can affect both comfort and health, especially when there are concerns about mold or other airborne contaminants within the home.
Thor offers professional air quality testing when there is a specific reason for evaluation. Samples are collected using proper methods and analyzed by Pro-Lab, a certified laboratory, to ensure accurate and dependable results.
Results are typically available within 36–48 hours and are clearly explained so you understand what was found and whether further action may be recommended.
