I live in the San Francisco Bay Area. Low humidity and mild climate year round.
I don't have any problem with mold or humidity in my vented crawlspace, but it is musty and I want to prevent that musty air from getting into the house.
What's the best way to determine how much I need to do? I have looked at a lot of videos and web sites, but I'm left with some questions, like:
- should I block the vents?
- do I need a humidifier? guessing not with low humidity in this area, but I don't know if encapsulation might change that
I don't want to create a problem.
adding some details:
there is fog, and it can be very wet, but I think the amount of moisture we get crawlspace-wise is minimal
drainage around the house is really good in terms of grading and downspouts
55yr old house and I've lived in it for 20 years and the only time it gets a little too wet is when there are heavy rains for a week, and even then, there aren't puddles, just more moist, and then it drys out pretty good
we definitely get a fair amount of wind
there is absolutely no mold as configured
I think the crawlspace is probably fine as-is, except when the air pressure is such that the crawlspace air is sucked into the house, which is the only reason that I want to do this.
