We are a home inspection, radon testing and thermal imaging company servicing southeastern WI called Inspect The Best WI (Lic # 3324-106). Our goal is to help you prepare your home for sale or to assist you in making the decision to purchase a house. We offer InterNACHI's Buy Back program. Instead of a few dollars of warranty coverage, if I miss anything during your inspection, InterNACHI will buy the entire house back from you for the price you paid for it! That's a tough warranty to beat. Check out my website at www.inspectthebestwi.com for more details. Also, as part of our home inspection process and no cost to our clients, we inventory the home's appliances and run them through a recall check system to see if any recall have been issued for those appliances. If there has been a recall notice on any of those appliances you will be contacted to set up an appointment to have those items fixed. The appliances will then be registered so in the event a recall should happen while you own the appliance, you would be notified. To set us apart we use a FLIR thermal imaging camera to pinpoint problem areas before they are visible and more costly to repair. Let us use our training, building science knowledge and FLIR IR camera to help evaluate and look for issues.

"Paul was thorough and professional. He communicated well during the entire process. The report was very detailed. He was very responsive to all of the questions I had for him before, during, and after the inspection. We will use him again."

‘Due Diligence, llc’ is a veteran owned/operated professional home inspection company. While not all home inspectors bring the same level of experience to the table, our sole inspector, with over 25 yrs remodeling and 15 yrs forensic failure analysis, brings more than most. We pride ourselves in providing unbiased, thorough inspections and take the time necessary to insure our clients have a full understanding of any/all concerns identified.

"As a local Realtor, I've worked with many inspectors. But since working with Jeffrey, he is now my #1 go-to Inspector on my speed dial! I can confidently refer him to my Clients, knowing they will be getting the best of the best! While working with Jeffrey, I've been blown away by his attention to detail, how knowledgable he is & how he's able to explain even complex issues in layman's terms - for anyone to understand! His inspection report is the most organized home-owners guide, that I'm confident you will reference the whole time you live in your home! With the level of service you receive... you'll be shocked with how affordable his rates are! There are inspectors out there charging a lot more, and you get a lot less than what Jeffrey will do for you! Hire Jeffrey... you won't be disappointed!"

Radon Detection and Reduction questions, answered by experts

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

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.

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.

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

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.
