What’s the cost of excavating around the house perimeter?
I am planning on performing a retrofit of my 1950s ranch-style house to air seal and increase the R-value of the walls. I am planning on adding 4 inches of rigid foam on the exterior of the house. Part of the plan is to bring the foam down to the footings of the basement walls.
My question is this: What is a reasonable price to pay for excavating a trench, 6 to 8 feet deep by 2 feet wide, around the house? I have about 100 feet of basement wall that needs to be excavated. Can you give a $/linear foot cost?
