Retaining Walls for Kirkland properties
A retaining wall holds back soil and the water in it. Water is the part people underestimate. When the soil behind a wall stays saturated through a Seattle winter, the pressure on it climbs, and walls built without drainage lean, crack and eventually fail. Every wall we plan starts with where the water goes.
Original ramblers and split-levels next to new construction and townhomes, especially around Totem Lake and Houghton. We work across Juanita, Finn Hill, Totem Lake, Kingsgate, Rose Hill, Houghton, Lakeview, Moss Bay, Market and Norkirk.
Level yards
Turning a slope into usable lawn or patio space.
Driveway cuts
Holding back soil beside a driveway or parking pad.
Terraced beds
Lower walls in steps for planting.
Kirkland conditions that affect your retaining wall
Slope and access
Finn Hill, Juanita, Houghton and the bluffs above the lake have steep lots. Kirkland’s permit exemptions don’t apply in steep slope, landslide or other critical areas, so walls and grading there get reviewed.
Soil and settling
Glacial soils on the ridges are generally firm, while lower areas near Juanita Bay and creek corridors can be wetter and softer.
Rain and drainage
Slopes push water downhill toward patios and foundations. Drains behind walls and along patios matter as much as the concrete itself.
Details that help us price your retaining wall in Kirkland
You don’t need answers to all of these. They’re the questions that shape the design and the price.
Height and length
Tallest point and rough length. Height counts from the bottom of the footing.
What’s above
A driveway, house, fence or slope above the wall adds load.
Water
Wet spots, seeps or water running down the slope in winter.
Property line
How close the wall is to a neighbor.
Existing wall
Photos of any old wall, rockery or timbers to remove.
Access
Can equipment get in, or is it hand work?
Options to talk through
| Type | Good for | Keep in mind |
|---|---|---|
| Poured concrete | Driveway cuts, taller walls, tight spots near property lines | Needs a footing, forms and cure time; can be smooth or board-formed |
| Concrete block (CMU) | Structural walls with a stone, stucco or painted face | Reinforced and grouted on a footing |
| Segmental block | Garden terraces and lower walls | Taller walls need geogrid back into the slope |
Permits for retaining walls in Kirkland
Under the building code used across Washington, retaining walls over 4 ft measured from the bottom of the footing to the top of the wall, or walls holding back a surcharge such as a driveway or slope, generally need a permit and often an engineered design. Kirkland lists rockeries and retaining walls over four feet as permit work, and its exemptions don’t apply in steep slope or other critical areas. Kirkland Development Services makes the call for your property, and we’ll tell you what we expect before you commit.

Typical market ranges, not a quote from Seattle Concrete Contractors. These are ranges other Seattle-area concrete contractors publish for this work (Seattle Concrete (seattleconcrete.com) service pages (another Seattle wall builder lists $30–$100 per sq ft of wall face by type), checked November 2026). Your price depends on size, access, removal, base work, finish and permits, and on conditions at your Kirkland property. We give a written quote after we understand the job.
Retaining Walls in Kirkland: quick answers
Do I need an engineer?
For taller walls, walls with load above them, and walls in critical areas, usually yes. We’ll tell you early.
Why do retaining walls lean?
Usually water pressure behind a wall with no drainage, or a footing that’s too small for the soil.
Do I need a permit for concrete work in Kirkland?
Kirkland lists retaining walls and rockeries over 4 ft tall as needing a permit, and requires a Public Works permit for driveway replacement or any work in the right-of-way. Exemptions don’t apply in steep slope or other critical areas.
