Marvel Radon Experts

I just had a pleasure of having Marvel Radon install mitigation system in my house. They are professional fair and reasonably priced. They took care of everything that they quoted me for. When they say they will re test and make sure radon is mitigated they mean it. First test after installation was still high they cam back made some adjustments and after second test its all working perfectly. I do recommend choosing fan cover for the outside it makes ii so much better. Re test were included in the quoted price. I am 100% satisfied and I recommend them to anyone !!

Marvel Radon Experts were great to work with. They provided a representative quote upfront and that is what I was charged after all was said and done. While the installation was expensive, it was within line (on the lower range) of other quotes I had received. The installation was fast and the workers were kind and respectful. They answered all of my questions and made sure not to proceed with installation until I was certain of the placement. The team scheduled a follow-up radon test to ensure the equipment was working properly. I would highly recommend this company for great service!

I had 3 distinct slabs to reduce radon under - my basement, slab on grade family room, and garage. It was a tough job, and the results speak for themselves.

These guys are fast, extremely effective, and most of all really easy to work with. I decided to go with a different radon fan and they were accommodating with the cost adjustments.

Here are the results:
Radon Test Readings Pre-Mitigation:
~11.0 in Basement (official home inspection determined a level of 8.0)
Family Room (slab on grade):
~3.0-4.0
Radon Test Readings Post-Mitigation:
0.3 in Garage
0.3 in Family Room
0.4 Basement

Note: to ensure accuracy, I delayed the post mitigation radon reading for 5 days after… read full review
