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.

Customer experience
What Burien 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
Slope Access, Drainage, and Permit Considerations
Toward Seahurst and Three Tree Point the ground falls steeply toward the water, and drainage routing becomes the dominant consideration before any structural stabilization begins. Foundation settlement on these bluff-side lots often involves both helical pier support and surface water management working together. Inland parcels in Gregory Heights and Boulevard Park sit on flatter ground with conventional access, though post-war crawl space construction still warrants evaluation for settling posts and deteriorated sills.
As of 2026, permit review runs through the City of Burien or King County depending on the parcel, and steep-slope overlay requirements may apply near the bluffs. We confirm the correct jurisdiction and engineering documentation needs before quoting, so the scope accounts for all review steps from the start.

Local questions
Burien Questions
Do you serve Seahurst and Three Tree Point?
Yes. We serve all Burien neighborhoods including Seahurst, Three Tree Point, Gregory Heights, Boulevard Park, and the Normandy Park edge. Response times are the same across the area.
My post-war house has a low crawl space. Can you still work in it?
Yes. Clearance affects duration and cost rather than feasibility. We measure headroom during the evaluation so the quote reflects actual working conditions, not assumptions.
Can drainage work reduce crawl space moisture in Burien?
Where bulk water is the source, drainage and discharge correction does more than any liner alone. A vapor barrier then handles remaining ground moisture. We identify the water source before recommending either approach.
Does homeowners insurance cover foundation repair?
As of 2026, standard homeowners policies typically exclude foundation settlement caused by soil movement or poor drainage. Coverage may apply if the damage results from a covered event such as a burst pipe. We recommend reviewing your policy with your insurer before scheduling work.
When is the best time of year for foundation repair in Burien?
Foundation repair and underpinning can proceed year-round in the Puget Sound climate. Summer and early fall offer drier excavation conditions, but helical pier installation and crawl space work are not weather-dependent. We schedule based on your timeline rather than waiting for a particular season.

Areas We Also Serve Near Burien
West Seattle
West Seattle's hillside lots above Alki and Admiral face slope settlement and coastal bluff drainage. Seattle Foundation Repair uses interceptor drains, helical pier underpinning, and laser manometer elevation surveys to guide lasting repairs on Vashon till and glacial soils. Waterproofing and slab lifting are also common on the flatter residential parcels near Delridge and High Point. Some properties near Fauntleroy and Beach Drive fall under ECA steep-slope review per Washington state guidelines, and we flag that early so your project timeline stays realistic. Searching for foundation repair near you in West Seattle? We cover every neighborhood on the peninsula.
