' Thoroseal ' is a good product impo but not if you use it where it is not the correct situation,,, ' afraid to call a waterproofing company ' 'cause they'll fix AND guarantee their work ? ? ? doesn't sound as if you've much faith in yourself !
is this a 1/2 ( english ) below-grade bsmt ? just dig up the front of the house down to the footer & waterproof the wall,,, apply a protection course of miradrain/delta drain,,, install sump, pump, & riser for ' belt / suspenders ' approach,,, backfill & hand compact,,, leave w/proper positive drainage.
bearing in mind your very fine home was built in accordance with the building code, the front was never waterproofed - ONLY dampproofed,,, typically we charge $ 4,500 for a 25' townhouse while our competitors get 20 - 25% more.
lose the hydraulic cement - its nothing more'n a temp fix & is never intended to be permanent,,, caulk's another improper mtl,,, you need vertical SEALANT - sonneborn's ' sonolastic ' or meadows' ' sealtite ',,, NOTHING on the inside will EVER prevent water from penetrating the belowgrade brickwork,,, while its annoying & unsightly now, you're also experiencing structural damage albeit at a very slow rate,,, pay now or pay MORE later,,, MUCH more ! ! !
