Re: mold in crawl spaces

Rate this topic

Recommended Posts

The house where I am living now had a drain pipe break where water poured

down into the crawl space under the house. Prior to this we smelled a musty

odor coming from a vent in the crawl space. I was arranging for a home

inspector to check under the house to see what was causing this when the pipe

broke.

Obviously there had been a slow leak for an undetermined amount of time.

This of course explains the asthmatic cough again in the last few weeks, that I

only recently recovered from. Needless to say after battling mold in

multiple dwellings, I am devastated.

I am completely unfamiliar with crawl spaces, let alone mold growth in this

area due to a leak/flood. If anyone has had experience with this I would

appreciate any feedback. How are crawl spaces underneath a house remediated?

A similar thing happened to us. I have some " ideas "

about spraying with peroxide, or a humidifier loaded

with ammonia, and maybe some vent fans

down there, but nothing conclusive tried yet.

I would say that sealing around all pipes that lead into the

crawlspace is a good idea. Pay particular attention to the bath

shower area. If you have a shower, there is probably a gap

around the faucet that will be difficult to seal. I just put

a zip lock bag over the whole faucet with a rubber band when not

in use.

The pipes for the shower lead into the shower from the crawlspace,

and

the head needs room to pivot (on/off, hot/cold, etc..) This leaves

the gap around the faucet (where it pivots) leading directly to the

crawlspace. I would not have suspected

this gap had I not felt cold air pouring in around the fixture

one day. Hey, where's all that air coming from? Gulp !

Don't do this! You could damage your health far more than you imagine!

The thing many people don't realize is that all tile is porous, and the tile

needs to breathe on its back side.

READ YOUR LOCAL BUILDING CODE.. Talk to a pro about anything you do w.r.t.

your tile bathroom area..

Make sure you have a good building envelope and that that envelope is

insualated and has the vapor barrier facing inward if you are in a heating

area and outward if you are in a cooling area..

Crawl spaces need to be defined CLEARLY as outside of the building envelope,

and they should be ventilated. All openings through the building envelope

should be sealed fully. There can't be any leaks or condensation inside of

the walls or the humidity in there will soar and that means mold.

If that doesn't make sense to you, call a pro.

Here's an interesting link recommending that crawl spaces should not be vented,

etc.:

http://www.hgtvpro.com/hpro/bp_foundation/article/0,2617,HPRO_20146_3463221,00.h\

tml

It's not clear how you could remediate a crawl space following these

recommendations, but it makes alot of sense for new building IMHO, which I'm

beginning to believe is the best approach for most of us in ensuring that we

have the safest possible home.

Be well,

I'm a little confused. Were you referring to something

I said in my post below?

I followed the link.

Interesting idea. (I wonder though what would happen if there was a

leak in such a sealed crawlspace?)

My house is already built, and I've been disabled for years.

I agree with being " careful " in venting the crawlspace. That was my

intention. I did not want to draw in excessive amounts of moist air.

Just the opposite. That is why I had envisioned a manual control

over the fans (and having the intakes on the sunnyside of the house).

Still, a passive vent system (as most homes currently have) would

allow warm moist air in during the summer. I had not thought of that.

But, as you note, if the living space is a seperate enclosed space,

then everything should be OK (or perhaps I am just projecting from my

own case). Our house is well sited with no drainage problems.

If I were going to build anew, I would contemplate seriously the idea

of building on stilts about 8ft off the ground (as seen in Dr. Rhea's

book. What fun it would be to slide down a firemans' pole to get to

your car. To the batmobile ! ;)

Best,

Zippy

Actually- for humid areas the new thing-code in NC- soon to be code

in VA- is to close the crawl space-seal the floor and sides-and

either install a large capacity de-humidifyer, or heat and cool it

with the house- but no returns, and a pressure release outlet

the de-humidifyer is cheaper, but you have to have access to clean

the filter every 2 weeks or so.
