what they might try to sell you on could be what I've seen on some home improvement shows.. excavate around the entire house to apply the membrane to the exterior of the foundation wall, with drain tiles at the bottom, or similar inside, with breaking up the floor to install the drain.
That's the kind of stuff you have to do if there's lots of hydrostatic pressure from a high water table (basically build a boat hull) but that does not sound like your case. Yours seems to be water moving through to a lower place but finds the gaps around your water pipe. Maybe rubber in a can is a good solution here. But yes, call a pro.
