That's terrible as we were flooded last year when our sump pump broke down. What a mess, and being up in age I had hired someone to clean out our crawl space. After taking everything out and putting it into a staging area in our garage and throwing out the really soggy stuff, they then proceeded to get rid of the water, sanitize the area and then set up a dehumidifier, and four fans to run 24 hours a day for 3 days straight. Talk about noise.
While we had three days before they came back, my wife and I had gone through all the stuff set out in the garage and ending up throwing a lot of stuff, maybe 60% or more. Then we bought containers for the rest of the stuff that was to be put back into the crawl space. They came back and removed their equipment, and put all our remaining stuff back into the crawl space. Of course we did have a plumber replace the sump pump with a new one also. Glad that fiasco is over with.
