Interior drain tile runs roughly $60 to $120 per linear foot installed in Greater Cincinnati and Northern Kentucky, so a typical perimeter section lands in the low thousands. A sump pump with basin and discharge runs $1,200 to $2,500. Exterior excavation runs several times higher.
More detail
Pricing is driven by linear footage and by what has to be moved to get to it, which is why quotes for the same house can differ legitimately. The main line items in this market. Interior perimeter drain tile at roughly $60 to $120 per linear foot installed, including slab removal, gravel, pipe, and concrete restoration. Most homes do not need the full perimeter; a wall or two is common, which keeps the total in the low thousands rather than the high. Sump pump installation with basin, check valve, and discharge line at $1,200 to $2,500. A battery backup system adds $800 to $1,800. Crack injection at $400 to $900 per crack. Exterior excavation and membrane at several times the interior rate per linear foot, which is why it is reserved for cases that need it. What legitimately drives a quote up: a finished basement where framing and drywall have to come out and go back, a slab thicker than standard, limited access for material and debris, a discharge run that has to travel a long way to daylight, and any structural work discovered along the way. What should make you ask questions: a quote for the full perimeter when water only ever appears on one wall, a bid that omits the discharge routing, and a proposal that leads with an interior sealer or waterproof paint as the primary fix, which does not manage water pressure and is not a substitute for drainage. One genuinely optional item worth buying anyway: the battery backup. The failure mode that floods a basement is a storm that takes the power out while the water table is at its peak, which is precisely when a pump on house current stops. On warranties: transferable warranties are common in this trade and they are worth reading. What matters is what triggers coverage, what is excluded, and whether the transfer requires a fee or notice within a window.
