I am a "mold survivor" so to speak, after living in FL, and having a mold problem in my house caused by the hurricanes.
Well, first thing what one needs to do is get a face mask, so you won't breath in the mold spores.
Second, the problem needs to be found on WHY and WHERE the moisture came in. (Note: Mold spreads....sometimes, when you find mold in one spot, it's not necessary the area it originated.)
You got to get the area dried out....dehumidifier, BEEdry systems in the basements....expose to TONS and TONS of fresh air circulation (fan come sin handy). Whatever it takes.
Next, the choice is yours to hire someone to remedy the mold problem, or you can get the work done yourself (like we did...but, be prepared that you WILL get dirty, and it's really a lenghty job to get that done!)
I washed and sprayed EVERYTHING with straight, undiluted bleach, and a sanitizer I got from work. (Bleach will kill the root system and spores totally, and the sanitizer will inhibite re-growth. Do NOT mix the two, and let dry in between applications!!! FUMES!!!!)
It was at times bonebreaking.......but, we got it done, and I think we were the only house on the block actually NOT having any mold at all in the house
I guess, it all depends on how bad the mold situation is, but, having lived in FL I think my mold "tolerance" level is a bit higher then maybe others.
And, if I really loved a house so much, and I would find the problem on why the mold happened.....I would weigh my options, and maybe, just maybe, take on the fight to take on the mold and remedy the situation.
(Hint: One thing I WOULDN'T take on is a termite infestation, and I think that would be the time I would consider lighting a match........lol...yuk....lol
)
Good luck in whatever decision you make!
