"We had had a new kitchen put in and then a year later, we had had our kitchen floor redone and basement repaired after a flood in our house.  Water from our washer had flooded the kitchen and laundry room and then flowed through the floor into the basement theater room and rec room.  We had to have a new (porcelain) tile floor put in upstairs and new paint and carpeting throughout the basement.   The work for the new kitchen and then the flood required a huge amount of sanding, spackling and more sanding...etc. The dust in our house was a big problem afterwards from the spackle dust that accumulated  in our ducts.  We decided to have our ducts cleaned and found All States on Angie's list.   It went great!  They were on time, conversant about the state of our ducts.  They did the job.  I have noticed that the air is better in the house and we have much less dust on furniture!  Very happy with their services and I would definitely hire them again.

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 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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

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