5 Tips for Selecting The Best Radon Mitigation Company

5 Tips for Selecting the Best Radon Mitigation Company

Radon mitigation is a process that keeps the amount of radon in a property at a safe level. This is essential for any home, as radon is a highly toxic chemical that can cause sickness if you're exposed to it for prolonged periods. Given how complex radon mitigation can be, it’s important to find a company that can carry out the job to keep your household safe.

Although there are many companies that provide mitigation services, choosing the right one requires a thorough discernment of qualifications. That’s why when you’re looking for the best radon mitigation company, you should make sure to do the following:

  • Verify their license and certification
  • Ask about their experience
  • Secure their guarantees and warranties
  • Check out their reputation and references
  • Compare their prices to other companies

Following the above tips will help you gain a more thorough understanding of choosing the most qualified radon mitigation company. 

Verify The Radon Mitigation Company's License and Certification

One of the first things you must check is whether the company is licensed and certified to practice. These are very basic requirements, and if they don’t have them or are refusing to show them to you, then you should stay away from the company entirely. 

As stated, dealing with radon is very complex, and any misstep can be detrimental to your health and safety. Having a license and certification proves the company has undergone the proper training to deal with radon and they are legally allowed to receive compensation for it. 

Licenses may differ depending on the state you’re in—just make sure to check local regulations to ensure the company has the correct license to operate. When it comes to certification, on the other hand, try to choose a company that has national certification, such as the National Radon Proficiency Program (NRPP) certification. As stated by the Center for Environmental Research and Technology, Inc, a certification proves excellence and competence in the field—and the NRPP is one of the best available in the industry.

Ask About Their Experience

When working with any company, you will want to work with someone who has proven their capability of doing the job properly—and finding out about one’s experience will ensure that. 

The easiest and quickest way to check this is to ask how long they have been operating. Although the length of time a business has been operating is not a measure of how good a job it can do, it does mean that the company does well enough to stay open. Aside from that, companies that have been open for a long time will most certainly have handled more projects than those that have just newly started—which means they have more practical knowledge.

Beyond that, a more established company that has been operating for longer is likely to have better equipment than smaller contractors. This means more efficiency and better accuracy, as they are likely to know how to use their equipment well in their long tenure.

Secure Their Guarantees and Warranties

True radon mitigation professionals provide a written guarantee and equipment warranty if you avail of their services.

A guarantee is provided when it is found that you have elevated levels (above 4.0 piC/L ). The company will “guarantee” that their service and equipment will reduce it to a safer level and that by the time they are done, your radon levels are lower than 4.0. A warranty, on the other hand, means the equipment they provide should work perfectly for a certain period—and if any part malfunctions, they will replace it free of charge.

Having these prove two major points: they will do what it takes to lower your radon levels and they are committed to providing you with equipment that's sure to work. If a company doesn’t provide these, it could mean they aren’t sure they can handle the job or they provide cheap equipment. In either case, avoid a company that can’t provide either.

Check Out Their Reputation and References

A company that provides excellent service will be lauded by its customers, and it won’t be afraid to showcase the feedback of previous clients on its website. Meanwhile, a company that constantly does poorly will have negative feedback and will do its best to hide the problems.

A quick Google search will reveal much about a company. Check the reviews that previous customers have left, and watch out for any red flags. A company with excessively bad reviews is one to avoid—it could mean that their service is sorely lacking and that they haven’t been doing a good job. A company with a few bad reviews isn't necessarily a deal-breaker, though. If the company you're considering has a mix of good and bad reviews, read how they manage the complaints and strive to be better.

Compare Their Prices to Other Companies

When it comes to paid services, one of the biggest concerns for any consumer is the price. 

It might seem best to go with a company that provides affordable services, but if they are too affordable that could indicate a problem. If a company’s fees are too low, they might be cutting corners or skimping out on the materials they use, which means a poor service ethic in either case.

Find a company that is reasonably priced. More expensive does not necessarily mean better—but if the elevated price means better materials and more dedicated service, then it might be worth looking into.


Finding the best radon mitigation company to work with can be a challenge, but if you know what to look for, then you'll end up with a team that's worth your time and money. Remember to consider the company's experience level, certifications, and customer reviews.
