I'm not going to tell anyone to do this themselves, because certain types of mold can be harmful to your health. I however, chose to risk it and kill it myself. :) I actually took many precautions including a suit and mask and even eye protection. I used different concoctions which I mixed and sprayed and scrubbed based on extensive research and depending on the surface involved. I won't put these recipes here because I don't want anyone to blame me for their mold illnesses, but some batches had hydrogen peroxide, some had borax, some used bleach and some used vinegar - do your own research or even better, call a pro.
First things first, find out where the water's coming in and stop it. The main culprit here was a hole in the ally's sidewalk where water from the neighbors gutter was pouring into and finding it's way into my basement. This had been going on for years!
I pulled up the loose top cement layer and poured a soupy mix of mortar in there so it would hopefully follow the path of the water and fill in the small areas. I then packed the hole with 35 gallons of stone and dirt and other matter. I packed in there with a broom handle and patched it with cement. This will do the trick, but is still a temporary fix since all the sidewalks will be fixed in the summer and this area will require trench drain.
Second thing is to get a dehumidifier in the basement running 24/7 - done. Water was dripping against the front of the building from the front gutters which were leaking from 2 small holes. These were sealed with gutter sealant . Problem fixed - sort of. Since this house is over 200 years old, the front basement will need to be monitored over time to see if there are more areas of water infiltration.
The back basement will also need a sump pit and pump as it seems to fill from below ground.
