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.

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.
