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

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.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
