Foundation Repair & Evaluation in West Seattle
We evaluate and repair foundations across West Seattle, from the bluff lots above Alki to the ridge homes in Admiral and the flatter parcels along Delridge. Hillside settlement and coastal bluff drainage shape most of the work we do here.

Common concerns
Foundation Warning Signs Worth a Second Look
Most people reach out because something has changed and they cannot tell how serious it is. That is a reasonable place to start.
Cracks you cannot read
A diagonal line above a door frame or a stair-step crack in block work means something. Width alone does not tell you what. We measure the pattern and the movement before calling it anything.
Floors that have gone out of level
Sloping floors, doors that bind in one season, a gap opening where a wall meets the ceiling. These often trace to crawl space framing rather than the perimeter foundation, and the fix differs completely.
Water arriving every wet season
Puget Sound rain is sustained rather than dramatic, which is why basements leak in January and stay dry in July. Whether you need drainage or waterproofing depends on how the water is getting in.
Quotes you cannot compare
Two proposals, two numbers, no shared language. We itemise quantities, depths, and exclusions so you can see what each line is actually paying for and where the two differ.

How an Evaluation Works
Four steps from the first message to a decision you can actually make. Nothing is committed until you have the written scope in front of you.
-
Step 01
Tell us what you see
Send the observations, photos, and rough timeline through the quote form. We'll tell you what an evaluation would examine and what it cannot establish from a photo.
-
Step 02
On-site evaluation
We record accessible observations and take multi-point laser manometer elevation readings, so floor differentials are measured rather than estimated by eye.
-
Step 03
Findings and limits explained
You get a plain explanation of what the findings do and do not indicate, including the limits of a visual assessment and whether an engineer should be involved.
-
Step 04
Written scope and next step
If repair is warranted, the proposal states quantities, depths, permit notes, and explicit exclusions. If it is not, we say that too.

Coverage across Alki, Admiral, Fauntleroy, Delridge, and High Point
Customer experience
What West Seattle Customers Say
The evaluation was calm and thorough. They explained which cracks were cosmetic and which were load-bearing, and gave us a written scope with clear exclusions before any work.
Homeowner, Queen Anne
Queen Anne, WA
Our floors had started to slope near the kitchen. They audited the crawl space, showed us the failing posts, and fixed the moisture source too, not just the framing.
Homeowner, Ballard
Ballard, WA
We wanted a seismic retrofit before selling. They walked us through the SDCI Standard Plan and were honest that our older masonry needed an engineer's review.

Local knowledge
Working on West Seattle's Slopes and Bluffs
West Seattle sits on a peninsula of glacial deposits cut by ravines, and the difference between a flat High Point lot and a bluff parcel above Alki changes the whole scope of a project. On the steeper streets off Admiral Way and Beach Drive, we plan access before anything else: where a mini excavator can turn, whether spoils have to be carried up a stair run, and how far a discharge line can be routed before it needs a pump.
Several West Seattle parcels fall inside Seattle's Environmentally Critical Areas overlay for steep slopes and landslide-prone ground. That does not mean a house is failing. It means SDCI review asks for more documentation, sometimes including a geotechnical report, before a permit is issued. We flag that early so the timeline in your proposal reflects the real review path rather than an optimistic one.
Crews reach West Seattle from the north end of the peninsula, and we schedule around bridge and Delridge traffic rather than promising arrival windows we cannot keep. Work on narrow streets in Alki and Fauntleroy is staged so parking disruption is short and neighbours know what is happening.
The Homes We See in West Seattle
Much of West Seattle was built out between the 1910s and the 1950s, which means a lot of Craftsman bungalows on stem walls and post-and-pier crawl spaces, plus a large stock of mid-century daylight basements on the slopes. Later infill townhomes and view rebuilds sit on engineered footings and behave differently again.
On bluff-side daylight basements we most often find lateral movement in the downhill wall, water tracking along a cold joint, and crawl-space framing that has taken on moisture from a poorly routed downspout. On the older bungalows the recurring findings are unbolted sill plates, undersized girders, and post bases sitting on pier blocks that have settled unevenly.
We record what we actually observe on your property rather than assuming a neighbourhood-wide pattern. Two houses a block apart in Fauntleroy can sit on different soils at footing depth.

Local questions
West Seattle Questions
My West Seattle home is on a steep slope. Does that automatically mean a landslide problem?
No. A steep slope raises questions worth answering, but not every foundation issue on a hillside is a slope-stability issue. Drainage, fill, a leaking line, or deteriorated framing can produce similar symptoms. An evaluation with elevation measurements and a look at how water moves across the site is what separates them.
Do West Seattle projects need extra permits?
Sometimes. Parcels mapped inside Seattle's Environmentally Critical Areas overlay for steep slopes or landslide-prone ground trigger additional SDCI review and documentation, and a geotechnical report is occasionally required. We check the parcel before quoting so the permit path is priced honestly.
Which West Seattle neighbourhoods do you cover?
Alki, Admiral, Fauntleroy, Delridge, High Point, and the surrounding streets, plus nearby Burien, Georgetown, and Beacon Hill. If you are close to the boundary, ask. We will tell you plainly whether we serve your address.
Water comes into my Alki basement every winter. Is that waterproofing or drainage?
It depends on the entry pathway. Water running down a slope and pooling against the wall is usually handled with interceptor and footing drains plus a planned discharge. Water pushed through the wall under hydrostatic pressure calls for interior drainage and sealing. We assess the cause first rather than selling one system by default.
How long does a West Seattle evaluation take?
Most single-family evaluations take one to two hours on site, depending on crawl-space access and how much of the perimeter is reachable. You get the observations, the elevation readings, and a clear statement of what a visual assessment can and cannot establish.
Can you work on a lot with no driveway access?
Usually yes, though it changes the method and the cost. Restricted access often favours helical piers or pin piles installed with smaller equipment, and spoils handling becomes a bigger line item. We note access constraints in the written scope so there are no surprises.
Still have a question?
Send us what you're noticing and we'll tell you plainly what it might mean and what an evaluation would examine.
