I’m not sure if this community is the right place to discuss this, but there is a tech angle, so here goes nothing.
A few years back I bought an AirThings Wave. It was on sale at Best Buy, it was a bit nerdy and I knew radon was a potential issue for anyone, so I spent the $200Cdn. AirThings’ system was a bit clunky and junky, but over the years they have managed to improve it enough that I no longer have a lot to complain about. Unfortunately they’ve kind of obsoleted my device with their newer system, because it needs a “home hub” to provide Internet access, and it’s not compatible with my first gen system. (The first gen just used bluetooth and your phone.)
Anyway, it turned out that radon in my house was marginally high. I checked the government website, and they suggested it be mitigated, but as I wasn’t using the basement for anything but my nerd equipment and various other clutter, I didn’t investigate actually doing it. I assumed it was stupidly expensive. Having recently looked into it, it’s about $2500Cdn to have a professional do a mitigation.
Times have changed, people are working from home, some more space would be nice, and I would like to build (and have humans occupy) a room in my basement. So I need to do the mitigation.
So my point of this message is to ask some questions:
- Have YOU checked your radon? Do you even know it could be an issue?
- Do you have any experience with DIY-ing a mitigation? If so, please share any advice or cautions.
In my house I have a sump pit, so I have investigated using it as the “collection well” for the radon pump. This entails buying a purpose built lid to seal off the sump pit. I also have a rough in in the basement for a bathtub that I need to deal with (looking for advice on what to do… it’s open to the ground, and I don’t want to permanently disable it because one day I want a bathroom there.) There are significant hairline cracks in the floor that I will also probably need to address, and I don’t really know much about that process either (advice appreciated.)
One thing I don’t have a clue about, is that there are a number of deliberate holes in the floor. There is a floor drain direct into the sump pit, meant to handle a leak in the water heater. There is a pipe beside the furnace that is a drain for any moisture from it (from the A/C I presume.) There is another pipe/drain for the HRV. I presume I will have to close over the floor drain, and find some way to seal around the two pipes (spray foam maybe?)
Anyway… TL;DR: If you have advice about a DIY radon mitigation in a sump well, please share.
