"Andrew is top notch in my book, and I am so very glad that I hired him. I was told by another professional a long time ago that I needed two suction points since I had two cement slabs, and Andrew assured me that it typically is not needed, and if it is for some odd reason it won't cost me anything more than what his original quote was. All questions answered with confidence. I was notified when he would arrive on the day that was agreed. The suction point was discussed and ultimately my own locations he selected without argument he worked with me and suggested area's that would work out. He assured me that if the levels of radon are not below 2 then he would come out again to modify the size of the fan and or add another suction point. when he started working once the suction location was agreed upon, work went very fast with his assistant outside and Andrew in the basement holes drilled suction tubing installed and vented exactly where I wanted it. Outstanding job Andrew!!!! "

Craftsmen Home Improvements, founded in 1991 is an award-winning contractor specializing in roofing, siding, windows, and decks. Craftsmen uses the highest quality materials, backed by the longest, most extensive product warranties available. Awarded the Angie's List Super Service Award every year since 2004. We offer James Hardie siding, and Vinyl siding, Owens Corning and GAF shingles, Andersen Windows, Marvin Windows, Hayfield Windows, Richlin Windows, Pella Windows. (We have a 5 window minimum) (Gutters only in conjunction with roof or siding), (We do not do roof, siding or window repairs)

"For a number of of years we deferred replacing the vinyl siding on our house that was poorly installed and had deteriorated horribly, but after our son and daughter-in-law had their home beautifully redone with Hardiboard siding installed by Craftsmen Home Improvements we knew it was our time. Based on my son’s experience and recommendation, we opted for CHI to install James Hardie siding and soffits and couldn’t be more satisfied with that decision. The work crew (Ray and Luis Nava) were fantastic in all ways; communication, skill and workmanship. They worked tirelessly and efficiently(even in some harsh winter temperatures) and always informed me of issues they encountered with our somewhat “wonky” house 😏 that they addressed with proper solutions. The end result is a stunning transformation of our house that only disappoints us that we didn’t do this sooner! Thank you CHI and especially Ray and his team!"

FAQs for radon gas abatement projects in Andover, MN

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
