not really much you can do if it is coming through the walls. Sealing from the inside won't work. To really solve the problem you'd have to dig out the foundation from the outside and waterproof it....of course that is expensive...and with a traditional philly rowhouse you have neighbors on both sides.....plus stone and mortar foundation walls aren't exactly known to be water tight to begin with.

if it is coming up through the drain that is a different story. There could be a blockage in your sewer line or in the main out in the street. It could just be a partial blockage or a capacity issue. Either way you should see if your neighbors had the same problems then follow up with the city.

another REALTOR I talked to today said they had 17 houses with leaks and or water problems from Sunday's storm. I had a leaking skylight that I (thought) I fixed 6 months ago.
