Waterproofing a Basement
Is a French drain the way to go?
I'm shopping around for a system that will flood-proof my basement.
During periods of heavy rain we get one to two inches of floodwater in
our basement. The water comes in where the floor joins the wall. A
contractor estimated that it would cost $3,700 to cut a trench around
the perimeter, and put in a sump and pump. Does this sound like a fair
price to you? And is there an alternative method of flood-proofing,
such as a sealant?

Tom Silva replies: Waterproofing a basement with a French drain is a lot of work and needs to be done be someone who knows what their doing. It sounds like your water problem is coming up from under the floor, so I think a
French drain and sump pump system will work. I don't know the size of your basement but $3,700 sounds very fair. Read more about French drains in Flood Watch.
