French Drain Installation in Mukilteo, WA
French drains, curtain drains and downspout tightlines in Mukilteo that collect water before it reaches the house and carry it to an approved outlet. Serving Old Town, Harbour Pointe, Mukilteo Speedway corridor and Picnic Point area.
Why Mukilteo yards hold water
Glacial till on the plateau, with sand and silt layers in the bluffs that are sensitive to water. Several areas along the shoreline are mapped landslide hazard zones. That is the root of most soggy lawns, wet crawlspaces and ponding patios we see in Mukilteo: water that cannot soak in perches on the hard layer and runs to the lowest point.
High bluffs above Possession Sound, cut by deep gulches like Japanese Gulch and Big Gulch. Harbour Pointe sits on the plateau above, mostly level. 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.
Possession Sound shoreline, the gulch streams and a scattering of wetlands carry buffers. Uncontrolled stormwater over a bluff edge is one of the biggest risks on Mukilteo properties. Where a drain can legally discharge depends on these features, so we plan the outlet first and the trench second.
Common french drains projects in Mukilteo

Permits & Rules
Drainage rules in Mukilteo
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 Mukilteo. 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 Mukilteo
We do not publish flat prices because no two Mukilteo sites are the same. These are the things that move the number most here.
Slope and access
Steep Mukilteo lots take smaller machines, more careful staging and sometimes engineering, which adds time compared with flat, open ground.
Soft ground
Where Mukilteo soils are soft or wet, over-excavation, fabric and imported rock are often part of the job, and we price that in up front.
Buffers and permits
Work near Mukilteo's rivers, creeks, lakes or shoreline can need permits and limits on where machines go. That affects scope and schedule more than price.
Haul-off and disposal
How much material leaves the site, and what it is, drives cost. Our own trucks keep that predictable on Mukilteo jobs.
When to schedule french drains in Mukilteo
French Drains in Mukilteo 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.
Mukilteo'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 Mukilteo
Mukilteo runs from the ferry landing and Old Town on the water up to the Harbour Pointe neighborhoods beside Paine Field. Much of the city is built on or near bluffs, so slope and drainage questions come up on almost every job.
We install French and curtain drains, catch basins and downspout tightlines across Old Town, Harbour Pointe, Mukilteo Speedway corridor, Picnic Point area and Olympus Terrace. Older homes and cottages in Old Town, view homes along the bluffs, and 1980s to 2000s subdivisions in Harbour Pointe.
Drain rock, fabric and pipe are delivered on our own trucks, and the excavated soil is reused for regrading or hauled away.
We also do french drains nearby in Lynnwood, Mill Creek, Everett and Edmonds. See everything we do in Mukilteo, read our full guide to french drains, or browse all service areas.

Questions
French Drain Installation in Mukilteo: FAQs
Will a French drain fix my wet yard in Mukilteo?
+
Often, especially combined with regrading. Glacial till on the plateau, with sand and silt layers in the bluffs that are sensitive to water. A drain plus better grading handles most of what that causes.
Where can drainage water go in Mukilteo?
+
To an approved outlet: a storm system, a dispersion area or an infiltration trench where the soil allows. Possession Sound shoreline, the gulch streams and a scattering of wetlands carry buffers.
Do I need a permit for a French drain in Mukilteo?
+
Usually not for a small yard drain. Storm connections or work near streams, wetlands or slopes can need approval from the City of Mukilteo. We confirm before digging.
How much does french drains cost in Mukilteo?

When is the best time to schedule french drains in Mukilteo?
+
French Drains in Mukilteo 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.
Is it safe to take a tree off a Mukilteo bluff?
+
It can be, done right. We usually leave the stump and roots in place on a slope so the soil stays held, lower the tree in sections instead of dropping it, and keep heavy equipment back from the edge.
Water runs over the bluff on my lot. Can you fix it?
+
We can collect it and carry it where it belongs, usually with drains and a tightline down to an approved outlet rather than letting it sheet over the edge. Work on a mapped slope may need engineering, which we flag up front.
What is the difference between a French drain and a curtain drain?
+
They are built the same way. A curtain drain is placed across a slope to intercept water before it reaches the house; a French drain collects water where it already pools.
