"Best description? Superior work. Thoughtful interaction and patience with the many questions. This was my first experience with work of this nature. Bo, the manager, could not have been more helpful. Alex and Ford worked endlessly to mitigate the mold and at the same time were informative and attentive to my questions. Excellence is the word that describes both their effort and the manner in which they took time to educate me on the remediation. Bo went out of his way to respond to both issues and questions."

‘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!"

PLEASE CALL FOR QUICKEST RESPONSE TIME --Donn Anderson is a Certified Master Inspector®. He began working in construction in the mid 60’s. He started Anderson Home Inspection and performed his first professional home inspection in January of 1995. He has inspected over 12,000 homes in Southeastern Wisconsin since then. He has been a member of the American Society of Home Inspectors – Great Lakes Chapter since 1996. He served as the Education Chairman for the Milwaukee Chapter of the Wisconsin Association of Home Inspectors from 1996 – 2009. He is a member of the National Association of Certified Home Inspectors and is a Certified Master Inspector®. He received his Real Estate license in the mid 1980s. Donn was a co-author of the jurisprudence exam for licensing Wisconsin Home Inspectors. He holds licenses as a WI State UDC Building Inspector, an FHA 203k Consultant, he is certified as a Residential Measurement Provider by NEHA-NRPP to test for Radon, the second leading cause of lung cancer in the US. He works as an expert witness for homeowners who have been exposed to substandard construction and home inspection practices.

"I was in the middle of a recent home Refi to get cash out for a new roof and new windows but the credit union wanted a professional report of some interior water damage that was noted during the appraisal process. Donn, from Anderson Home Inspection, was my inspector 20 years ago when I originally purchased my duplex. I contacted Donn and explained the situation and he was very understanding of the need and urgency to get the report for the bank. We scheduled a time 2 days later. Donn quickly assessed the interior water damage and then used his very cool drone to inspect the roof. He took pictures of the roof, interior water stains, and the attic. His report was completed and I submitted it to the credit union. His determination was the interior water stains were cosmetic and not structural. They were due to the poor condition of the valley and chimney flashings and would be corrected this spring when the roof is replaced. Thanks to Anderson Home Inspection my Refi proceeded without further issues and I'm on my way to a new roof and new windows. I have many friends that have used Donn's services and never hesitate to recommend him to anyone."

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.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

Yes, if high levels are detected, professionals can provide solutions for radon reduction.

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