The water comes back every storm. So does the guy who never finished.

Standing water and a wet basement are a grading and discharge problem before they are a French drain problem. We diagnose where the water actually goes, price the fix as one fixed number, and finish the scope we signed.

French Drain Installation Cost in Edwardsville, IL

Direct answer: French drain installation cost in the Edwardsville area runs roughly $40 to $95 per linear foot depending on depth, access, and where the water discharges. A bid well under that range is usually not a discount — it is a narrower trench, less stone, or a cheaper pipe, none of which appear on the quote and all of which decide whether the drain lasts.

The four variables behind French drain installation cost

Depth is first. A shallow interception run is a fraction of the excavation of a run taken down to a footing, and depth drives both machine time and spoil volume. Access is second: an open back yard is a different job from a trench between a foundation and a mature hedge that has to come out by hand.

Soil is third — dense clay is slower to cut and slower to backfill than sandy loam. Discharge is fourth and the one people forget. A run that daylights to lower grade is cheap to finish; a run that has to terminate at a pit and pump adds both hardware and an electrical connection.

Why two quotes differ without either being wrong

The most common reason for a wide spread is that the two crews are not quoting the same trench. One prices a full-width excavation with a generous stone envelope around rigid perforated pipe; the other prices a narrow slot with pre-socked corrugated tube. The linear footage matches, the price does not, and the difference is invisible the day after backfill.

The second reason is the discharge. If one bidder has assumed daylight and the other has priced a pit and pump because the lot has no fall, that alone can account for a couple of thousand dollars, and only one of them has actually looked at the grade.

Making bids comparable before you choose

Ask every bidder for the same five lines: trench width, trench depth, stone type and volume, pipe type, and the discharge point. Any bid that cannot produce those is not a bid you can compare, and asking for them tends to move the numbers closer together on its own.

Then ask what happens if the system does not move water after the first heavy rain. A written answer to that is the part of the quote that is actually worth money.

French drain installation cost questions

How much does a French drain cost per linear foot?

In the Edwardsville and Madison County area, a yard run discharging to daylight typically runs $40 to $75 per linear foot, and a foundation perimeter run $55 to $95 per linear foot. Terminating at a pit and pump rather than daylight adds roughly $900 to $2,400 for hardware and the electrical connection.

Why is one French drain quote half the price of another?

Usually because the two crews are not building the same trench. Trench width and stone volume are the largest cost inputs and the least visible on a quote, so a narrow slot with pre-socked corrugated pipe can be quoted at the same linear footage as a full-width stone envelope around rigid pipe. The difference is undetectable once the trench is backfilled.

Is a French drain cheaper than a sump pump system?

For yard water, usually yes, because an exterior run that discharges to lower grade needs no hardware and no power. For a basement below the water table, a drain alone often cannot solve the problem, and the honest comparison is not drain against pump but which combination the site actually requires.

Does French drain cost include restoring the lawn?

Frequently not, and it is worth asking directly. Excavation leaves a scar the width of the trench plus working room, and putting back sod, planting beds, or a section of driveway can be a meaningful line of its own. Get restoration itemised rather than assumed, so the comparison between bids stays honest.

What we put in writing before anyone digs

Fixed-price written quote before we break ground. Trenching turns up surprises; the price does not move because of them unless you approve a change order in writing first.
Zero-obligation site visit. If the honest answer is that the water is doing what water should do and you do not need a drain, that is the answer you get, in writing, at no cost.
The diagnosis names where the water comes from before it names the product. Grading, downspout discharge, and the water table get checked first; a French drain is a conclusion, not an opening bid.
Full-width trench, wrapped stone, and rigid perforated pipe as standard. We do not install narrow single-pipe trenches or pre-socked corrugated sections, because those are the installs that fail in year three.
Itemized scope showing linear feet, trench depth, stone volume, and discharge point as separate lines. No lump-sum 'drainage work.'
A named discharge point on the plan, with the permit or easement dependency listed separately so you can see which clocks we do not control.
If the system does not move water after the first heavy rain, we come back and correct it at our cost, not yours.
