- What sets me apart from other top inspectors is rather than spending 2-1/2 to 3 hrs. merely documenting the home's structure, systems, and components, and identifying deficiencies and potential problems; I focus upon teaching you about the home. Yes, it will be me, not a (surprise) employee, who will be serving you. Rather than simply enabling you to make informed decisions regarding your contract to purchase, I am enabling you to understand the specifics of your future home, which thereby enable me to teach you how to operate its systems most efficiently, reduce your energy costs, and how to maintain your home and protect your investment. You needn’t ask if you can accompany me and ask questions — I will arrive about an hour before you to set up my program, and document exterior conditions. Upon your arrival we will enter, conduct a detailed orientation, then inspect the home together. During which I’ll explain everything and answer any questions you may have. When we’ve completed inspecting, we’ll review the draft of the upcoming report, so you’ll know what issues will be in the report before we leave. Please be prepared to spent 4 hours with me. Why hire an inspector whose services merely meet Licensing and Certification minimum requirements which focus only upon protecting your contractual needs by identifying deficiencies and concerns? When for the same investment, you can participate in an LBI Education Inspection which in addition to providing you with a more comprehensive report, also teaches you all about the property, answers your questions, and provides a report created to serve as an informative manual similar to what is in the glove box of your vehicle.

Radon Detection and Reduction questions, answered by experts

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.
