Notes
- Where the number comes from. The national price for interior basement waterproofing is $75 per linear feet — interior drain tile pricing published for 2026, $50–$110 per linear foot. Labor is about 60% of that. Cement Masons and Concrete Finishers near Florence, SC average $47,220 a year against a U.S. mean of $60,050 — a factor of 0.786 — so the labor half is scaled by that and the material half is not.

- Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
- What is in the price: breaking out the slab at the perimeter, the drain tile and gravel, a wall vapour barrier, re-pouring the concrete, a sump pit and pump.
- What is not: a battery backup pump, exterior grading and downspout work, foundation crack injection, and finishing the basement afterwards. These are the lines that turn a $9,808 quote into a $12,260 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

What the quote should include
The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $9,808 and something a quarter higher.

This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $6,539 – $14,385, that is not automatically wrong — but it is the question worth asking out loud.
