"not that great. basically paid $99 to get an estimate. included cleaning roof and minimal repairs. took a while to get appointment, and then when they came, they didn't even do the work! gave a really big estimate and then re-seheduled to have someone else do the work. they wouldn't totally replace the roof, gave different estimates to repair, I went with a different company to do a full roof rplacement."

Radon Detection and Reduction questions, answered by experts

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

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

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 average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.
