Licensed home inspector working for mainly buyers and sellers in the States of Minnesota and Wisconsin. Starting fee for inspections are $275.00. I am a 1 employee company which is owned by myself, not a franchise. All fee's are to be paid at the time of service's.

"In June of 2018 Steven Hatcher from SafeGuard home inspection came and inspected the home we were purchasing. The report he gave stated little to concerned about so we believed everything was great and went forward with the purchase. However when we then moved in it’s been nothing but problems and at this point it has financially ruined our family. The things he missed are staggering. Plumbing, electrical and structural. We got two licensed plumbers who are home inspectors and one electrician. All of them said he is either blind, ignorant and incompetent or he did a professional favor for the seller who was also a supposed licensed home inspector. Or all of the above. We can’t use the washer because it’s plumbed into the sump pump tied incorrectly into the sewer line. We can’t use the dishwasher because the drain line was put in the main sewer line and caulked to seal it, this was blatantly visible and not code. Shower put in upside down, sink not mounted or plumbed correct. Exposed wiring and so much more that it take a book to write it all down. He is not an inspector but a fraud and I’m sure lazy because he did a lousy job. We can’t drain water we barely can use one toilet. We are devastated. We talked to a lawyer but it would be over 20k, the work is over 50k or more. If he just did his job and caught even a fraction of the major code violations we would never had bought. We put our life savings in to buy and now we have no way to fix this we may have to just walk away. The inspectors we paid after the fact couldn’t believe he could be that bad. If we gotten a real inspector we wouldn’t be in this mess. We found out any fool can be an inspector in this state there are no requirements. We found out the hard way and it cost us everything. If we could give him lower than an F we would. Please don’t ever ever use Him."

Radon Detection and Reduction questions, answered by experts

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.

Through air sampling devices and surface swabs in key areas of concern.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.

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.

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.
