"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

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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 for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.
