"Mike, of MCL, made an appointment to review the project and showed up on time. He is very knowledgeable and clearly went over all technicalities needed to take care of our radon gas problem. The next day he sent a quote. The job was finished on time at the quoted price, work was very professional and neat. I would definitely recommend MCL to complete mechanical work of this nature."

"I wanted to share with you that my home inspector (Bill) truly went above and beyond for me today and far exceeded my already very high expectations! I hired MichiganPro.com for a termite inspection and well water analysis for my Veterans Affairs mortgage refinance requirements. Instead of getting what he needed and getting out or rushing through things, Bill not only let my son and I follow him around, he patiently and thoroughly answered our 10,000 questions about our house. And most importantly for us, he pointed out every little thing around our house that has the potential of becoming something more, even though those things were not directly related to what we hired him for. And as a HUGE added bonus, he gave us great tips and tricks to save a ton of money by easily and efficiently fixing everything ourselves. In my opinion, he genuinely went the extra mile to make sure that I was a very satisfied customer and very well informed homeowner! If you ever need it, MichiganPro.com Home Inspections is truly your best bet!"

Radon Detection and Reduction questions, answered by experts

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

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.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
