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 Lake Charles, LA average $52,840 a year against a U.S. mean of $60,050 — a factor of 0.88 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for cement masons and concrete finishers near Lake Charles, LA, so this is the Louisiana state average, SOC 47-2051.
- This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Lake Charles, LA, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
- 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 $10,440 quote into a $13,049 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.

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 $6,960 – $15,311, that is not automatically wrong — but it is the question worth asking out loud.
