French drain: what is it?

The French drain, or foundation drain, is a perforated pipe laid around the foundation to collect groundwater and direct it to the outlet or sump pit. Over the years, sand, silt and roots can clog it.

We clean the accessible drain and inspect it by camera to see its real condition. If the inspection shows a larger repair is needed, we explain the options clearly.

Signs of a clogged French drain

Water or dampness in the basement

Water marks at the base of walls or on the floor, especially after rain or snowmelt.

Sump pit that fills quickly

A pit that fills faster than before or a pump that runs constantly.

Problem that keeps coming back

Even after a surface cleaning, water comes back to the same spot.

French drain: price, when to act and how it works

How much does cleaning a French drain cost?

The price depends on the length to clean, access (cleanouts, sump pit) and the condition of the drain. We provide a free quote before the work.

When should you have your French drain checked?

As soon as water appears in the basement, the sump pit works harder than before, or before buying an older house with an unknown history.

How does the service call work?

We access the drain, clean it with a hydrojet and run a camera to assess its condition. You receive the observations and, if needed, our recommendations.

Questions about this service

Can you replace a French drain?

Our work covers cleaning and inspection. For a full replacement, tell us about your situation and we will honestly tell you what we can do.

Is my French drain connected to the sump pit?

Often yes: the drain brings water to the sump pit, from where the pump removes it. The camera can confirm this in your building.

How often should it be cleaned?

There is no single rule: it depends on the soil, the age of the building and its history. A camera inspection helps decide.

A question about this service?
