Cleaning mold behind the wall by placing dry ice cubes
I had a minor water leak 3 weeks ago, and today I discovered that I have some mold behind my flooring trim. I cleaned the mold and sprayed it with the bleach, but I am wondering how do I clean the mold which is behind the wall?
I read about dry-ice blasting, but it won't work since it needs a direct access.

I was thinking placing dry ice blocks on the floor next to a wall, and waiting for couple of hours - the cold seems to be strong enough to penetrate the wall and freeze what's on the other side.

Has anyone tried it? Do you think it would work?

the way for that is basically dry-ice sandblasting.

directly on the surface.

any way you cut it, the interior of the wall is not going to be disinfected and dried until you... open the wall up.

first, make a small hole and insert a flexible inspection camera's snoot. if you indeed have mold, have fun.

don't know what the pros would say on here, but I'd take down the drywall and redo it.

Wandering somewhat off your question, but have you reported the leak to your insurance company? Being "minor", it may not seem significant enough to involve them, and it likely will eventually affect your premium...just something to consider.

if I were an agent, I'd want to save Consolidated Federated Unipurposal Insurance money up front by fixing the issue when it's $3000 and not $35,000. and incidentally much of it would then be the deductible. let that mess fester, and you can get actual structural damage.

call the man. even the inspectors they send out know more than you and I do.
