"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

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.
