Attic Mold


By the way, the guy I had talked to said I didnt need to actually spray the mold. He said by leaving the buckets of bleach up in the attic for a couple days it would kill the mold.

Said to do it when I was leaving for a weekend.

Have you ever heard of someone doing this?

Yes, I've heard of this method.
The efficacy of this method depends on how enclosed your
attic is. The bleach will evaporate a bit faster than H2O and
"fogg" your attic. But if you have reasonable ventilation, it
will take a longer period of time as opposed to the fine spary
method. Direct contact kills the mold quicker. You do not have
to saturate the sheathing. Spray away from you and wear
a breathing mask and eye protection.

This is the least expensive method and there are other chemicals
not as noxious but costs a bit more.
MOLDSTAT is pretty nice smelling product but expensive.
You can order this through Ebay.
I use this for hand sanitizing and spraying around inside areas.
If you are afraid to the bleach, go to HomeDepo or Lowes
and ask around for what they have.

Attic Mold


Saying, "the more the better" on a DIY site is not a smart thing to do. Some may take that the wrong way and put vents every 2 feet on their roof.

I know a few home inspectors. They know the code book and thats about it.

Still, if you have too much ventilation, it can cause problems. I've seen it first hand many times, not just pictures in a book. No disrepect.

Attic Mold


I'm afraid that I have to side with MJW, too much attic ventilation CAN be detrimental, especially when proper air sealing has not been performed. I've seen studies showing an energy LOSS when ventilation and insulation are added to an attic without proper air sealing. Unfortunately, many home inspectors are completely oblivious to this. I don't know your knowledge of building science Oldeye, and I do agree with some of your points, but facts are facts, and there have been some pretty major breakthroughs in the area of home performance/building science in recent years.

You are right about some home inspectors.
However, you are wrong about them knowing "code book and that's about
it". The ASHI/NAHI Certified home inspector do not come cheaply. Most of my collegues have 4,000 plus inspections completed and keep up with continuing education(minium is 20 hours per year of class education).
Some of them are code certified. Most of us are very familiar as we attend
code seminars from time to time, especially if there are major changes, in building codes, that is.

Understanding codes is one thing but being an ASHI Certified home inspector is another. You can be both, though. Most of us do not do
home repairs except our own. It comes in as a conflict of interest in
our SoP manual. There is an one year off limits clause for repairs to
homes we inspected. Unless the damage was done during the home inspection.

Okay, let's not get carried away.

I assumed that the living space was well sealed up.

The subject is about getting rid of mold on the cheap.
We do not want to load the fellow up with all kinds of
heavy hitting building science scare!

I get no pleasure out of dragging any thing further.

Good insulation and ventilation are critical parts of
maintaining attic health. There are million ways to do it.
My suggestions are based on my personal experience and
training. Take it of leave it.
