Crawlspace in Vancouver. Small crawlspace and the house is pretty much at grade so there isn’t really much room for passive crawlspace ventilation. As such, we opted for a system with a fan on a humidistat. In any case, delays in the installation of the system and wet weather have combined to create a perfect environment in the crawlspace for mold to grow – spots can be seen on pretty much every TJI .

What’s the process to deal with this. Calling a remediation contractor would pretty much be the last resort, but what we’re thinking of is cutting a few holes in the subfloor to enable more ventilation in the meantime and throwing some fans/heaters/and a dehumidifier down there for a few days before getting someone with a wire brush and moldicide. Does that seem like we’re on the right track? Any help here would be greatly appreciated.

You do it yourself, and if the future owners have problems, they'll own your car, house and family.

Call a remediator and indemnify yourself.

So now that you broadcast it to the world, and someone gets sick, it's no longer an accident, it's gross negligence. Meaning you knew about it and knew it should of been remediated but chose to not do it. That is the scenario if that becomes your choice. Gross negligence in this country can be criminal. Especially if there's great bodily harm or worse.

Never wire brush mold, you're just spreading it.

Areas that are good for mold growth can also be good for rot. I would have used a wood preservative on all exposed surfaces, it will prevent all sorts of problems for years to come.
