I recently inspected a 1980s home with a lot of basement renovations. There was a dug-up area next to the sump pump that puzzled me. There was moisture around this spot, but no visible pipes or clues about what was done. The nearby walls had new drywall, so I couldn’t see if there were any visible defects. Has anyone seen something like this or have any insight on this? The seller’s agent said there used to be a shelf there but it was taken out, which confused me even more.
