I believe that radical methods of combating mold and fungus should be used immediately. Several times I tried to get rid of the raid on the walls with the help of chemicals, but this did not help. And the problem was solved only after I made water proofing basement. Rather, I called specialists and they suggested what needs to be done. Now the house is dry, warm and there are no unpleasant odors. And we changed the drainage system, so there are no problems in rainy weather.
