What does Slab Leak Repair Cost?
It is important to have an idea of the cost of slab plumbing repairs. We are not going to give you the basic "it depends" answer. What we will do is give you several estimates based on a common or most frequent situation where older drain and sewer lines are replaced under slab.
Here are the Assumptions....
Some trenching will be necessary to replace drain lines from the building perimeter to the city's main sewer line.
Tunneling will be required for the under slab drain and sewer line replacement.
Under slab plumbing repair costs can easily vary up to 50% or more because of rocky or difficult soils that have to be trenched and tunneled. Other factors that can increase the cost of an under slab leak repair job are trees, larger lots requiring more trenching, larger houses requiring more tunneling, and drain lines under concrete patios and driveways.
