Linda arranged the details and scheduled the work as soon as possible for them and me. Eric, the technician who did the work was amazing. Friendly, knowledgeable, very professional. Was a good experience and I’m glad the repair is finished.

Radon Defense did an excellent job with replacing my impaired existing system. The team was focused and professional and I really appreciate how they answered all my inquiries in detail, teaching me about the system overall.

The installers were right on time, answered my questions, did the installation and were gone. No mess, no dust, even tho they had to drill holes in my foundation, which they plugged back up. The vent pipe is innocuous as well. If you're not actually looking for it, you can't see it. Their contract electrician was also fast and very professional.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
No two jobs are the same. Each job is priced separately
What is your typical process for working with a new customer?
We can quote most projects over the phone. Sometimes it is necessary to come out to the property and do an onsite visit, so we get you the right price the first time.
What education and/or training do you have that relates to your work?
All of our crew leaders are always taking classes to improve.
