Serving the Greater Ashland area of Michigan and Wisconsin. Specializing in basement waterproofing, crawl space repair, gutter installation, concrete lifting & leveling, attic insulation, foundation repair, & commercial foundation services. FREE estimates available.

"Worst workmanship I’ve ever seen. Basement still leaks, the system they installed does not drain water into the sump crock looks like water is now being diverted under the floor. Owner never came out to look at what his employees call a finished job. I was quoted by Dennis $56 a foot in the basement and when I got upstairs it was actually $59, red flag. I was quoted and designed a system and they installed another. Look at pics and you decide if you want to hire these hacks and liars. One other thing the workers mixed the Qiukrete next to my furnace that was running and the whole house was filled with concrete dust."

Radon Detection and Reduction questions, answered by experts

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

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.

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.
