Possible Mold remediation needed in basement
Project Location: East Lyme, CT
Have an unfurnished basement- 1/3 with cement-2/3 raised dirt crawl space-tall enough to stand and bend-with ceiling insulation-no actual ceiling. Most interested in having some kind of sealant over the dirt and a solution to the ceiling insulation-, which constantly falls down. There is no access to the basement from inside the house- Entry only through the bulkhead -at the side of the house. thanks, Steve

We have two cracks in our foundation that we would like to be repaired. Both cracks are vertical from the floor to the sill. The larger of the cracks grows as it transitions vertically to about 1/8th of an inch. This one has seepage during long rain storms.
