Mold remediation, fire/water damage restoration. We have been providing quality work for home owners and businesses in Southeast Wisconsin for over 30 years.

"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."

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."

"My A/C stopped working at the beginning of a streak of hot weather. I called Seider when they opened at 7:30AM. She took my information and told me they wouldn’t be able to make it until after 5PM as they were fully booked for the day. Also was told after hours rates would apply. At that point I was just happy to know someone would be coming. Especially since it was also the day before a holiday. Not much more than an hour later I got a call from Brandon, a Seider technician. He said he was about 10:minutes away and would it be okay for him to come now. That was more than fine with me. He arrived a short time later. We greeted one another and headed to the backyard where the unit is. He told me he was pretty certain that he knew what the problem was as he was familiar with the model that we have. And, he was right. He removed the failed part. Showed it to me and explained the problem. He retrieved a new one from his truck and installed it. He asked me to turn the air on. I was able to do that with my phone. And, viola! The compressor started right up and continued to run. Before Brandon arrived and replaced the part it would start but then stop after a few seconds. It’s now been about 10 days and the system continues to work like a champ. Thank you Brandon and Seider. It’s getting to be time to replace my furnace and Seider is at the top of the list for that work!"

Radon Detection and Reduction questions, answered by experts

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.

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.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.
