How waterproofing companies usually price
Waterproofing companies inspect first, then give a written estimate per foot of drain or per crack, with pumps and dehumidifiers as separate lines.
Start from your own hourly cost with the labor rate calculator, then check each price against the ranges above.
Where the ranges come from
10 of the 11 services carry a range. Each one comes from a koira.ai calculator that lists the cost guides behind it and the date they were checked: basement waterproofing cost calculator, french drain cost calculator, foundation repair cost calculator, mold remediation cost calculator. They are national figures; the calculators scale the labor share to your state's wages when you enter a ZIP.
Lines marked "Set your own" have no range we could source well enough to publish. Price them from your own hours and parts.
What it takes to deliver this menu
The starter kit behind these services: concrete saw with dust control; rotary hammer or demo hammer; moisture meter; shop vacuum with hepa filter; wheelbarrow and buckets; crack injection gun and supplies; multimeter; respirators and eye protection. The full tools list adds the pro kit and van stock, with maker prices where we could check them.
