French Drain Installation in Lake Stevens, WA
French drains, curtain drains and downspout tightlines in Lake Stevens that collect water before it reaches the house and carry it to an approved outlet. Serving Lakeshore, Frontier Village, Cavalero and Hartford.
Why Lake Stevens yards hold water
Glacial till and outwash over most of the city. Some newer areas sit on sandy outwash that drains well; others on till that holds water. That is the root of most soggy lawns, wet crawlspaces and ponding patios we see in Lake Stevens: water that cannot soak in perches on the hard layer and runs to the lowest point.
Rolling upland that drops to the lake on all sides, with steeper ground on the east and north shores and the Cavalero plateau to the west. Slopes push water onto the next lot down, and flat ground leaves it nowhere to go, so the drain route and the grade around the house matter as much as the pipe.
The lake itself carries shoreline rules, and Catherine Creek, Stevens Creek and their wetlands carry stream and wetland buffers. Where a drain can legally discharge depends on these features, so we plan the outlet first and the trench second.

Permits & Rules
Drainage rules in Lake Stevens
Small yard drains usually do not need a permit, but connecting to a storm system, working near a stream or wetland, or changing how water leaves the property can need approval from the City of Lake Stevens. Outside city limits, Snohomish County Planning and Development Services (PDS) handles it.
Water can go to an existing storm system, a dispersion area or an infiltration trench where the soil allows. It cannot be pointed at a neighbor or dumped over a slope.
Cost & Timing
What affects the cost of french drains in Lake Stevens
We do not publish flat prices because no two Lake Stevens sites are the same. These are the things that move the number most here.
Slope and access
Steep Lake Stevens lots take smaller machines, more careful staging and sometimes engineering, which adds time compared with flat, open ground.
Buffers and permits
Work near Lake Stevens's rivers, creeks, lakes or shoreline can need permits and limits on where machines go. That affects scope and schedule more than price.
Size of the property
On Lake Stevens acreage, longer haul distances inside the property and bigger volumes change the math. Bigger jobs often cost less per unit.
Haul-off and disposal
How much material leaves the site, and what it is, drives cost. Our own trucks keep that predictable on Lake Stevens jobs.
When to schedule french drains in Lake Stevens
French Drains in Lake Stevens goes best in the drier months, when soil compacts properly and trenches stay open. Wet-season work is doable with erosion control and the right material, and we plan for it in the quote.
Lake Stevens's till soils hold water through the winter, which is when drainage problems show up. That is a good time to see where water goes, and the dry season is the time to fix it.
Where We Work
Drainage work across Lake Stevens
Lake Stevens wraps around the largest natural lake in Snohomish County, and the city has grown fast through annexations and new subdivisions. Waterfront lots, hillside lots and new construction all make up the work here.
We install French and curtain drains, catch basins and downspout tightlines across Lakeshore, Frontier Village, Cavalero, Hartford, Machias and Soper Hill. Older lake cabins and homes on the shoreline, 1990s to today subdivisions on the uplands, and some rural acreage on the edges.
Drain rock, fabric and pipe are delivered on our own trucks, and the excavated soil is reused for regrading or hauled away.
