Due to heavy rainfall the crawlspace of the house has water now and a contractor suggested exterior waterproofing for around $4K. This is causing me a lot of problems (mold etc) so I don't mind fixing it, just not expert enough to know this would fix the problem.
Tried to get educated online (interior waterproofin vs exterior waterproofing, etc etc), but still not sure if the proposal below would solve the problem. Any advise is highly appreciated, thanks!

Proposal from the contractor :
Below grade waterproofing:
Installation of below grade waterproofing around the home. We will dig around the perimeter of
the home from 1 to 2 ft., inspect the mortar joints and bricks, if any deficiencies (holes) are
found we will patch the hole with hydraulic cement. Clean up the wall and apply fluid
waterproofing. Also, install a drain pipe all around the home with fabric sleeve and gravel on
top, and back fill.
They have already done this to pump water out :
Installed sum pump at crawlspace, dug out a 1’ foot hole at lower spot of the house and drained
the water away to avoid the formation of mold at the inside of the house.
