"I bought a home built before 1978 and found that there was some asbestos floor tile in the basement. I reached out to D&H Demolition and they immediately came out to take a look at the project and provided a free estimate. They were very helpful and answered all my questions which made me feel a lot safer about the situation. I hired them and they took care of the work the very next day! Overall I was very pleased with their price and quality of work. Highly recommend!"

"We needed the fan replaced on our radon mitigation system. Atlantic Radon responded quickly, confirmed appointment time, called to see if he could arrive early (which he did), had the appropriate replacement for our 32 year old unit, and completed the job in a short time. The "tech" was the owner - pleasant, knowledgeable, easy to work with. Recommend Atlantic highly."

Radon Detection and Reduction questions, answered by experts

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

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.

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

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.

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.
