My former neighbours and I had our places waterproofed in 1993, with weeping tiles added, because of termite problems ( if you buy a Riverdale house that the sellers claim doesn't have a termite treatment history ... be very sceptical! ), but the critters can return anyway. They did, next door, this past summer. For that reason I think it is actually better to have an unfinished basement in certain parts of town ( I do ) because you can see the walls and main floor beams at all times. I had the wood framing and panelling of my basement washroom replaced with metal studs and drywall this summer for just that reason, though the amount of new damage, low down at floor level, was very minor.
This may all sound terribly expensive but, compared to the average cost of paying a monthly fee in a condo, the occasional expenses that I've incurred when things have "gone wrong" has worked out far less, over the full 17 years that I've been in the house.
