There is no typical charge as every job has different problems associated with it.
It shouldn’t cost much to excavate your basement floor if you have a concrete saw, jack hammer, someone to carry the old concrete out, a truck to haul it away, a place to dispose of it, a shovel to dig down below the concrete, someone to carry the dirt out, someone to carry the ton or more of crushed stone down to bed the drain tile in, the drain tile, a way to mix concrete, someone to carry the concrete down to the basement and pour it into the hole, someone to work and smooth the concrete. Now figure out just what you would charge to do this for someone else. Don’t forget to include the cost of your insurance, office expenses and help, and a couple hundred other costs that go into running a business when you figure this. How about I pay you $4.00 a lineal foot to do mine?
If you think they are too high, do it yourself. This isn’t heart surgery.
