French drain pricing

How much does a French drain cost? The honest answer is that no serious contractor can give you an exact number without seeing your home first. What we can share, though, are the ranges we actually bill across Lanaudière after 30+ years on the ground, and the variables that move the bill up or down. This guide covers French drain pricing for the four most-requested jobs: new installation, high-pressure cleaning, targeted repair and iron-ochre treatment. No pressure, no gimmicks — just the numbers as we see them in the field.
