"The work that Dave’s company performed was great with the exception of the living room, that ended up being mid-matched. Dave’s crew let me know that because of this they would paint the whole living room. They asked me to call and set up an appointment and I did. The day came and nobody showed up. I called Denise and she stated her crew called in sick and they were leaving town the next day. She would have Dave call me. He didn’t, so I txt him the following week and he called and said it would be more money, which it shouldn’t as I was previously told they mid-matched it so they would make it right. He was supposed to call later in the week and never did. I find though everyone was nice, the professionalism was lacking. I would not use again because of this."

Radon Detection and Reduction questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
