"Joe knows radon.  He put in a system on short notice in my two story colonial with full basement.  I shopped around to two other Radon contractors and his was either the lowest or close to it, but he was also the first that I could schedule.  FYI: He said the overall cost was less because there was an existing sump pit.  We scheduled for the morning and I gave him access to the house.  By the time I got to the house at 11am he was done and gone with only the odor of fresh caulking, PVC pipes, and the muffled whirl of a fan.  The installation was professional with an acrylic custom cover cut to fit over the sump pit to keep debris out.  Plenty of signage and meters on the installed equipment indicating fan circuit, basically informing me and any future owner, "Do not shut this Off".  The radon reading in the basement was 25.4.  Joe was confident that once the system was in, it was going to be less than 1 (less than 4 is safe per EPA rules).  we tested three days later, and the official reading was 0.9.  Looking at the quality of work, I'd use him for any other venting related needs in this or future house.
He has an "F" grade from someone who complained about something not working after three months and he was going to charge a labor fee.  This is just my 2 cents, but don't think that was fair, as he does give you a 7 year warranty.  He warrants equipment for 7 years and will replace out equipment but there is a labor charge.  This is clearly spelled out in his contract.

Radon Detection and Reduction questions, answered by experts

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

Yes, many systems include warranties for performance. Confirm terms with your installer.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
