5 Questions to Ask Yourself When Selecting a Radon Testing and Mitigation Company


Radon testing and radon mitigation are highly specialized trades. Selecting the right radon company is an important decision. Radon is a dangerous gas that could impact your health, and high levels of radon can occur anywhere in the country. Which is why it’s crucial to test the radon levels in your home and have a professional radon mitigation team help address high radon levels. We have outlined five questions to help you select the best radon mitigation company.

1. Is the radon contractor licensed? 

There is not a national license for the radon trades. A client looking for a quality contractor should contact their State Radon Office to find out if there is a State specific radon contractors license. Many states do not have licensing programs for radon. If you live in one of these states, look to hire a radon contractor who is certified either by the National Environmental Health Association’s Radon Proficiency Program or by the National Radon Safety Board’s Certification Program. It is also wise to ask if the installer/employee is licensed or certified. 

2. Are they insured? 

Installing radon mitigation systems sometimes require some alterations to the house. Make certain to check your contractor’s insurance certificate to be sure it has proper coverage and is up to date.

3. Did you receive a detailed scope of work and estimated price? 

Before starting any work, either testing or installing a system, ask the radon contractor for a detailed scope of work and how much this work will cost. Make sure both parties agree on this proposal before proceeding, this helps both the contractor and you as the customer be satisfied with the work. 

4. Do they provide a guarantee? 

The EPA recommends that radon levels be lowered below 4 picocuries per liter. Most radon mitigation contractors will provide a written guarantee of performance. 

5. Do they have good references or online reviews? 

A reputable contractor is always eager to offer references to potential clients. When a contractor readily provides references, it showcases transparency and confidence in their work. Speaking with past customers or reading online reviews can offer valuable insights into the quality of their work. You can also ask the company about other aspects such as cleanliness, punctuality, and overall customer satisfaction. Seeking and obtaining references stands as a powerful tool in distinguishing between exceptional and subpar radon contractors, ensuring a positive and reliable experience for you.
