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 in New York average $72,630 a year against a U.S. mean of $60,050 — a factor of 1.209 — so the labor half is scaled by that and the material half is not.
  • 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 $5,066 quote into a $6,332 invoice, so ask about each one before signing.
  • Why state matters more than people expect. Materials ship at national prices; crews do not move. New York sits above the national mean by 20.9%, which lands on 60% of the job and moves the total by $566.
  • Use this as a bid check, not a quote. It prices an average job in an 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.

60 linear feet of interior waterproofing in New York

$5,066 is the typical figure, and bids on the same scope normally land between $3,377 and $7,430. That is 60 linear feet at $84 each.

Why this is not the national number

The same job at the U.S. average comes to $4,500 — this one is $566 more.

Cement Masons and Concrete Finishers in New York average $72,630 a year against a U.S. mean of $60,050, from the Bureau of Labor Statistics OEWS release for May 2025, SOC 47-2051. That is about $35 an hour, a factor of 1.209.

Labour is 60% of this job and material is the other 40%. Only the labour half is scaled by state.

$3,039 of labour, $2,026 of material.

Interior or exterior

Interior drain tile is what this prices: break out the slab at the perimeter, lay tile and gravel, re-pour, and pump out. It manages water rather than excluding it, and the wall stays damp.

Exterior excavation removes the soil to the footing, seals the wall from outside, and installs drainage there. It is the real fix and it commonly costs two to three times as much — more where there is a deck, mature planting or a driveway in the way.

Neither is dishonest. They solve different problems and a contractor who only offers one should be asked why.

Diagnose before you buy either

Water on a basement floor comes from surface water, a high water table, plumbing, or condensation, and they need completely different work. Tape a square of plastic sheet to the wall for a couple of days: moisture on the room side is condensation, moisture behind it is water coming through the wall.

That test costs nothing and it eliminates the most commonly misdiagnosed cause.

What is not in this figure

A battery backup pump, exterior grading and downspout work, crack injection, and finishing the basement afterwards. The last one is the large hidden number if the basement was finished before.

Reading a real bid against this

Three quotes on the same scope should cluster. One well under $3,377 usually has something left out of it; one well over $7,430 is a harder job than average, or a crew pricing to stay away.
