Since basement slab leaks occur under a concrete slab foundation, they are hard to detect and prevent and it’s important that the problem is addressed as soon as possible. If pipes that are run under a basement foundation corrode or shifting soil makes them leak, significant damage can occur inside the home.
According to Angi and HomeAdvisor, the average cost of slab leak repair ranges from $630 to $4,400, with the national average at $2,290. Factors impacting the repair cost include detecting the location of the leak, how difficult it is to access the leak location, work and materials required to repair the leak, labor costs, if excavation is required, and if the foundation and slab will require repairs.
Basement slab leaks can lead to significant damage, including foundation cracks, unpleasant odors, mold and mildew, standing water, low water pressure, and higher water bills.
