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.

Why Lake Forest Park Homeowners Work With Us
City of Lake Forest Park permit requirements confirmed before quoting, not assumed from adjacent city rules
Crawl-space substructure audits mapping posts, girders, joists, and sill anchorage
Moisture source corrected alongside framing repair so decay does not return
Seismic retrofit scope explained as separate work from settlement repair
Documented laser manometer elevation surveys, not a single spot check
Coverage across Sheridan Beach, Town Centre, Lyon Creek, and McAleer Creek
Customer experience
What Lake Forest Park 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.

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.

Local knowledge
City Review and Hillside Site Access
Foundation work in Lake Forest Park routes through the City of Lake Forest Park building department rather than King County Development Services. Submittal requirements and review timelines differ from those of adjacent Shoreline and Kenmore, and confirming the applicable authority is part of scoping a project here rather than an assumption made after quoting. Parcels near the city boundaries can fall under a different jurisdiction, and we identify the correct department at the start.
Access across most lots is generally workable. Hillside parcels above the SR-522 corridor can present grade changes and limited turnaround for larger equipment, particularly where lots drop toward the creek corridors at Lyon Creek and McAleer Creek. We assess access constraints during the evaluation and note them in the written scope before work begins so there are no surprises on the day of the job.
Crews reach the area via SR-522 as part of our regular north King County coverage alongside Shoreline, Kenmore, and Edmonds. We schedule work efficiently alongside those areas rather than treating the city as a separate assignment with uncertain arrival windows.
Mid-Century Homes and Crawl-Space Framing
The dominant housing type runs from post-war and mid-century construction in the Sheridan Beach and Town Centre corridors to later homes on the hillside lots above. Homes from the 1950s through the early 1980s sit on conventional crawl spaces with post-and-pier supports, perimeter stem walls, and sill plates commonly built without anchorage. On these homes we most often record settled post bases, undersized or moisture-damaged girders, and cripple walls that were never braced.
Proximity to Lake Washington and the lake-corridor drainage patterns keep crawl spaces in the lower-lying areas wetter than inland properties of the same vintage. Where seasonal runoff moves toward foundation walls or crawl space vents, moisture becomes a persistent driver of framing decay. Correcting the drainage pathway and correcting the structural damage belong in the same scope for repairs that hold over time.
Newer construction sits on engineered footings with more predictable bearing conditions. Settlement is less common on those properties, but drainage and flatwork issues appear as downspouts route water toward foundations and concrete settles over years of wet winters. We record what we observe on your specific lot rather than applying a neighbourhood-wide assumption across the coverage area.

Local questions
Lake Forest Park Questions
Does foundation work in Lake Forest Park need a city permit or a King County permit?
Most parcels within the city route through the City of Lake Forest Park building department rather than King County Development Services. Properties near the Shoreline or Kenmore boundaries can fall under a different jurisdiction. We confirm the applicable authority before quoting so the review path in your scope is accurate.
My mid-century home has sloping floors. Is that a foundation problem?
In most homes of the 1950s to 1970s era, a sloping or bouncy floor traces to the crawl-space framing rather than the perimeter foundation. Settled post bases, an undersized girder, or moisture-damaged joists all produce that symptom. An evaluation maps the substructure with elevation readings so the repair targets the actual cause.
Is my older home's sill plate bolted to the foundation?
Many homes of that era were built without anchorage, but not all, and some have been retrofitted since. We check the actual connections in the crawl space rather than assuming from build year.
My crawl space near Sheridan Beach stays wet every winter. What causes that?
Near the lake and the creek corridors, drainage routing and seasonal groundwater keep crawl spaces wetter than the hillside lots above. The fix starts with identifying the pathway: surface runoff, a high water table, and downspouts routing water toward the structure each need a different response.
Do I need to fix the moisture source before repairing crawl-space framing?
They belong in the same scope. Replacing a decayed beam without correcting what wet it means the new wood follows the old pattern. Where moisture drove the damage, source correction is part of a durable repair.
Can you do a seismic retrofit and crawl space repair at the same time?
Yes, and it is often efficient because both happen in the same space. They stay separate line items in the written scope, because bracing and bolting address different connections than restoring settled supports.

Areas We Also Serve Near Lake Forest Park
Shoreline
Shoreline's mid-century ramblers and 1950s-era split-levels, sloped west-side lots toward Innis Arden, and bluff parcels near Richmond Beach put crawl-space moisture and drainage routing at the center of most projects. From Echo Lake to Ridgecrest and North City, Seattle Foundation Repair matches the repair method to each property's soil bearing conditions, crawl-space framing, and construction type (2026 service area).
View ShorelineKenmore
Kenmore sits at the north end of **Lake Washington** in unincorporated **King County**, where the terrain shifts from shoreline flats along the lake corridor to hillside lots rising above it. Crawl-space moisture and drainage are the most common findings here, shaped by elevated seasonal groundwater near the lake and runoff that concentrates on sloped parcels above it. Homes in the Wayne and Moorlands neighborhoods carry the post-war and mid-century crawl-space construction common to north King County: settled post bases, undersized girders, and sill plates built without anchorage. Foundation work in Kenmore routes through **King County Development Services** rather than a city building department, with submittal requirements and review timelines that differ from incorporated cities to the south and east. Confirming the applicable authority before quoting avoids a scope priced to the wrong review path. Parcels near the Bothell or Shoreline city boundaries can fall under a different jurisdiction, and we identify the correct department at the start rather than after work is underway. The older housing stock along the **SR-522** corridor runs from the 1950s through the 1980s: conventional crawl spaces on post-and-pier supports with cripple walls that were commonly never braced. Seismic retrofit questions come up alongside crawl-space framing work in the same evaluation. Newer subdivisions in Arrowhead and the Northshore area sit on engineered footings where settlement is less common, though drainage and flatwork issues still appear as lots age.
