Kirkland · King County
Excavation Contractor in Kirkland, WA
Foundation digs, footings, utility trenches and building pads in Kirkland, dug to spec by an owner-operated crew with its own excavators and dump trucks. Serving Juanita, Finn Hill, Totem Lake and Kingsgate and the rest of Kirkland.
What the ground is like for excavation in Kirkland
Hills rising steeply from the lakeshore, with Finn Hill and Rose Hill on the uplands and ravines and wetlands between them. That shapes every excavation job here: where the machine can sit, how trucks get in and out, and where the spoil goes before it is hauled away.
Glacial till over most of the uplands, with outwash sands in places and soft deposits in the Totem Lake and Juanita lowlands. On a Kirkland foundation that decides how deep we go to reach bearing soil, whether unsuitable material has to be over-excavated and replaced with compacted structural fill, and how we keep water out of the hole while forms go in.
Lake Washington shoreline, Juanita Creek, Forbes Creek and the Totem Lake wetlands all carry critical-area or shoreline rules. If your footprint, trench or driveway lands near any of that, the excavation plan has to respect the buffer, and erosion control goes in before the first bucket.
Common excavation projects in Kirkland
New home and ADU foundations
Footprints for new houses, ADUs and garages on infill and teardown lots around Juanita and Finn Hill, dug to the elevations on your plans and ready for forms.
Hillside cuts and daylight basements
Excavation on sloped Kirkland lots, with spoil hauled off as it is dug instead of stockpiled on the slope, and temporary erosion control in place first.
Over-excavation and structural fill
Where Kirkland ground is soft, we dig out the unsuitable material and place compacted structural fill in lifts so the footing bears on something solid.
Utility and water line trenches
Trenches for water, power, sewer and gas service from the street to the house or shop, backfilled and compacted, anywhere from Totem Lake to the edge of Kirkland.
Tight-access digs
Compact excavators for narrow side yards and alley-access lots in Kirkland, with mats down to protect the driveway and the neighbors' property.

Permits & Rules
Excavation permits and utility locates in Kirkland
Inside city limits, the City of Kirkland handles building and grading permits. Properties outside city limits fall under the King County Department of Local Services. Foundation excavation is usually covered by the building permit, while grading or fill over set volumes, or any work in a critical area, can need its own approval.
Before any digging, Washington law requires a utility locate through 811 at least two business days ahead. We place that call on every job, and we pothole near marked lines instead of trusting paint alone.
Cost & Timing
What affects the cost of excavation in Kirkland
We do not publish flat prices because no two Kirkland sites are the same. These are the things that move the number most here.
Slope and access
Steep Kirkland lots take smaller machines, more careful staging and sometimes engineering, which adds time compared with flat, open ground.
Tight lots
Narrow side yards and alley access in Kirkland mean compact equipment and shorter truck loads. We plan it so it costs less than it could.
Soft ground
Where Kirkland 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 Kirkland'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 Kirkland jobs.
When to schedule excavation in Kirkland
Excavation in Kirkland 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.
Kirkland'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
Excavation across Kirkland
Kirkland stretches along the east shore of Lake Washington from Houghton up through Juanita and Finn Hill to Kingsgate. It has some of the strictest tree rules on the Eastside and a lot of high-value homes on tight or sloped lots.
We dig foundations, ADU and garage footprints, septic and utility trenches, and building pads across Juanita, Finn Hill, Totem Lake, Kingsgate, Rose Hill, Houghton, Market and Bridle Trails. From mid-century homes on Finn Hill to high-end new construction in Houghton and Market. Teardown and rebuild projects are common.
Our trucks run in and out on I-405, NE 85th St, NE 124th St and Lake Washington Blvd, so spoil haul-off and fill delivery happen on our schedule instead of a subcontractor's.
We also do excavation nearby in Redmond, Bellevue, Seattle and Woodinville. See everything we do in Kirkland, read our full guide to excavation, or browse all service areas.

Questions
Excavation Contractor in Kirkland: FAQs
What kind of soil will you hit digging in Kirkland?
+
Glacial till over most of the uplands, with outwash sands in places and soft deposits in the Totem Lake and Juanita lowlands. We read the ground on the site walk and spell out in the quote how footing depth, over-excavation and imported fill are handled, so there is no surprise invoice.
Who issues excavation and grading permits in Kirkland?
+
Inside city limits it is the City of Kirkland. Outside them it is the King County Department of Local Services. We confirm which applies to your parcel before quoting and flag anything that needs extra review, like a stream buffer or steep slope.
Can your trucks and excavator get onto my Kirkland site?
+
Almost always. We run compact and full-size tracked excavators and size the machine to the access. On tight lots we protect driveways and lawns with mats and stage trucks so the street stays open.
How much does excavation cost in Kirkland?
+
It depends on the site, so we quote after a free site walk rather than guessing on the phone. The biggest drivers in Kirkland are usually slope and access, tight lots, soft ground. You get a written number with inclusions and exclusions spelled out.
When is the best time to schedule excavation in Kirkland?
+
Excavation in Kirkland 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.
Do I need a permit to remove a tree in Kirkland?
+
Usually something is required. Kirkland regulates removal of significant trees on private lots, with different rules for hazard trees, development and critical areas. We assess the tree and tell you what the city will need before any cutting.
Can you prep a Kirkland teardown lot for a new house?
+
Yes. We demolish the old structure, remove the foundation and slab, take out the trees that are approved for removal, protect the ones being kept, and excavate for the new foundation, all with one crew.
How long does a foundation excavation take?
+
A straightforward residential foundation on an accessible site is typically one to three days of machine time. Add days for haul-off, difficult access, over-excavation or weather. We give a realistic window with the quote rather than a best case.
