I read so many contradicting things online: Some recommend dehumidiers (if so, which?), some advice against. Some recommend fans (which, how many, how/where to install?), some advice against. Some advice so seal the vents, some advice against. And yet others recommend to seal all vents but one.
I assume the reason is it highly depends on location (climate), vented vs unvented, dirt vs non-dirt.
I am located in the Bay Area (California), so for most time of the year the humidity outside is low so vented crawl space seems to be OK (I have been told).
However, I am impacted by this atmospheric river which made water seep into the crawl space (and unfinished basements): The concrete perimeter foundation and sill plates are soaked and in the part with the unfinished basement the floor is wet (little bit of standing water). I see fungus growing.
- Current measured humidity is 76.4%
- Total crawl space size: ~1100 sqft
- 4 vents (each corner)
- Crawl space has two parts:
- a small unfinished basement (small standing water, fungus growing on the floor, see attached picture)
- A larger crawl space (concrete perimeter, sill plates and wood is wet throughout the perimeter, see attached picture)
What is the most effective and quick way to dry this out as soon as possible?
