Moved into new (to us, built in 1980) house 2 years ago. Installed an Airthings radon meter a year ago. Levels get up to 400 Bq/m3 when all the windows are closed. Finally had a radon mitigation system installed. Will hopefully get to much safer level below 100 Bq/m3.

I see a few people have installed them in this thread. About how much does a system run cost wise?

    Wtf? You can buy some PVC pipe and a fan for like $50

    You can, but it also usually requires drilling through the concrete slab in your basement, and through an outside wall to your house.

    On top of that, you need to seal any holes that might exist in the concrete. Like around your sump or water inlet or God forbid any cracks.

    Then also, you have to make sure that you know how much air the fan is pulling, and have a way to monitor the flow so you know if it stops.

    In short, parts are cheap. Labor and continued safety aren't.

    Why would I pay a professional when I could do it myself for twice the price because of the never ending patches/"upgrades"?

    Because not everyone is competent or willing to do the research needed.

    I work with ventilation and installations and my home got around 400 becquerel. I have no fucking clue what more I can do to solve it without spending a fortune. If we had a basement I would go wild but we don't.

    Function control I would route through my home assistant server.

    Edit: I think I completely missed your point when I wrote this. I need to learn to read.

    You can also make your own parachute from a tarp and some paracord.

    It is a lot more complicated than that. Got the final report. They actually do flow testing to see how much air volume they need to achieve a specific vacuum differential, then select piping size and motor type to achieve the required results with the least amount of energy use.

    They used an RN2 motor with 4” piping for our house.

    Mine was $3031 CAD to have it professionally installed and certified.

    Ya, ours was right around the $3k mark. And that’s with a 5 year guarantee to keep it below 100 Bq/m3.

    Edit: final price was $2699 +tax CAD.

    These are the numbers I wanted.

    Our house has radon in the basement in the 300-400 range most of the time. I know I need something to clear it out, I've been concerned about how much it costs, so I've been stalling.

    Luckily, all the sleeping areas are far, far, away from the basement.

    I'll start putting the $3k together to have a system installed. Luckily I can split the costs with the other people who live here and also own the house with me....

    Depends on many factors. If there's an available sump pump, a radon lid is around $150. A fan is around $150. Between $100 and $300 for pvc, depending on number of elbows and distance. Assuming an open electrical breaker is available, and again depending on distance, $100 to $200 for electrical. $15 for a manometer. $20 for pvc cleaner and cement. $5 for tube of acrylic caulking. Total for parts, assume $500 to $850.

    Wothout a sump well, save $150 on lid, but x3 or x4 the pvc. Roughly $300 to $1000. Rental of a Hilti and diamond holesaw bit to add vents to corners of slab. So maybe $300 or so. Total around $600 to $1500, give or take.

    This is just parts. Labor will be $1k to $4k depending on location and complexity. If you can do it yourself, it's a significant savings. With an available sump well, it's an easy to medium difficulty project. Without one, it gets significantly more complicated.
