"A rough estimate for external waterproofing 88 linear feet with a
standard 6-7 foot deep dig as follows: We would excavate down to the
bottom of the footings, clean the walls, apply a rubberized urethane
by hand and also attach a dimple board on top. Install new weeping
tile and cover with 2 feet of 3/4" gravel, then cover with a
geomembrane. We would then back fill to grade.Rough Price: $10,000 +
HST $1,300 Total= $11,300"

How bad and where does it leak, the price is ok, but do you need all
that done. Maybe you do need it, and then you should consider a drain
tile system while its all dug up.

The estimate included that. Remember, this is Canada, they use slightly
different terms. I'd like to get that done to this place, but it would
require killing a lot of trees, and blowing away the rear deck and front
porch. I had one company in for an estimate, and he fed me a line of BS
about how OSHA didn't allow slit digging, and how they would have to
excavate yard ten feet back from the wall, and it would cost 25k for a
house not much larger. He then did a real slick high-pressure sales
pitch to try to get me to sign a contract for 8k for interior french
drains, right then. I basically threw him out. But I can easily see how
people who didn't grow up in the business would fall for it. I fixed
most of my problem with a little exterior regrading, and will handle the
rest when and if I re-do the deck, and get around to buying an epoxy
injection kit for a couple small holes where the form-board tie-bars were.

See Leza's other thread about the 90 YO house for more details. Reading
between the lines, I suspect some regrading and window repairs, and
replacing the gutters with the roof that probably needs replacement, may
make a big difference in the wet basement. In the other thread, we
recommended a site survey by a good inspector or GC. Nothing replaces
seeing it in person.
