ZD Properties was highly communicative and ensured they did the project right the first time. They excelled at working around other contractors we had onsite and met both the cost and timeline. Could not be happier.

Everything went well, SOC was on time, finish was good and price was great. I’d like to add that elevation was spot on, they set forms to exact fall for the job and we had no issues. It’s been two years and no cracks, no spalling and still looks as it did when they finished.

"Beatty home inspections was awesome to work with! Being a first time home buyer, we really didn?t know much about the process or what to expect. Chris?s expertise not only made us more knowledgeable about it ourselves, but put our mind at ease that the issue would be fixed. The issue was in fact, fixed. I would recommend him tenfold to anyone looking to get a radon mitigation system put in."

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

No, radon mitigation systems do not decrease home value or make a home harder to sell.

Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

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

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.
