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 Downtown Gig Harbor, Rosedale, Gig Harbor North, Purdy, and Kopachuck
Customer experience
What Gig Harbor 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.

Pierce County Permits and Peninsula Access
Foundation work within Gig Harbor city limits permits through the City of Gig Harbor building department, while parcels on the Purdy corridor, Kopachuck, and Fox Island route through Pierce County Development Services. Confirming which authority reviews your parcel is the first step in scoping a project here, because submittal requirements and review timelines differ, and a scope priced to the wrong review path costs time even when the work itself is straightforward.
Access across most of the peninsula is workable. The Uptown and Gig Harbor North areas have conventional lot sizes and equipment staging. Older harbor-side streets and waterfront lots can be narrower, with steeper grades above the marina and limited turnaround for larger equipment. We assess access during the evaluation and note constraints in the written scope before work begins.
Crews reach the peninsula via SR-16 over the Tacoma Narrows Bridge and schedule work alongside Tacoma and Bonney Lake rather than treating the peninsula as a separate assignment. The SR-302 corridor toward Purdy is also within our regular Pierce County coverage.
Waterfront Homes and Hillside Subdivisions
The older housing stock near the waterfront and in the original harbor neighborhood runs to mid-century and early post-war construction: crawl-space homes on post-and-pier supports with perimeter stem walls and sill plates that were commonly built without anchorage. Those homes show the recurring findings of that era: settled post bases, undersized girders, moisture-damaged framing near exterior walls, and cripple walls that were never braced. The marine climate keeps crawl spaces wetter than inland properties of the same vintage, and sustained moisture is a framing-decay risk rather than just an inconvenience.
Hillside lots above the harbor and along the Rosedale corridor introduce a drainage dimension that flat lots do not have. Where grades fall toward the water, runoff concentrates at foundation walls and can keep crawl spaces saturated through a long wet season. Interceptor drainage uphill of the structure often accomplishes more than anything installed at the footing line, and correcting the drainage pathway belongs in the same scope as any structural work.
The Gig Harbor North subdivisions and newer Uptown-area construction sit on engineered footings with more predictable bearing conditions. Settlement is less common there, but drainage and flatwork issues appear on these lots as they age. We record what we observe on your specific property rather than applying a subdivision-wide assumption to any part of the peninsula.

Local questions
Gig Harbor Questions
Does foundation work in Gig Harbor need a city permit or a Pierce County permit?
It depends on where the parcel sits. Properties within the City of Gig Harbor permit through the city building department, while those in unincorporated areas route through Pierce County Development Services. Fox Island and the Purdy corridor may follow different review paths. We confirm the applicable authority before quoting so the permit timeline in your scope is accurate.
My crawl space near the waterfront stays wet every winter. What causes that?
The marine climate and proximity to the water keep ground moisture elevated through the wet season, and runoff from uphill streets can concentrate against foundation walls on sloped lots. The fix starts with identifying the pathway: surface drainage, a high water table, and downspouts routing water toward the structure each need a different response.
My older harbor-side home has sloping floors. Is that a foundation problem?
In most homes of that 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 mid-century and early post-war homes on the peninsula 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.
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 Gig Harbor
Tacoma
Seattle Foundation Repair provides foundation repair, basement waterproofing, and crawl space services across Tacoma and southern Pierce County (2026 service area). Pre-war North End Craftsman bungalows and hillside parcels above Commencement Bay frequently present unbolted cripple walls, basement wall cracking, and slope drainage issues that require site-specific evaluation with laser manometer readings. Properties in the Stadium District, Proctor, Old Town, and Hilltop sit on glacial deposits where bearing conditions and water movement vary within short distances.
View TacomaBonney Lake
Bonney Lake sits on a glacially formed plateau east of Auburn where soils are mostly sandy glacial outwash and till, offering generally firmer bearing than the valley floors below. The plateau edge above **Lake Tapps** brings sloped lots where drainage routing and retaining wall condition come up in a share of evaluations, while the flatter interior of the city presents more conventional crawl-space and flatwork findings. Site conditions on a given lot depend as much on where it sits on the plateau as on any neighbourhood label. The dominant housing stock runs from the 1970s through the 1990s, with newer subdivisions in **Tehaleh** and the eastern plateau. Older homes in the Lake Tapps corridor commonly ride on post-and-pier crawl spaces where settling posts, undersized girders, and unbolted sill plates are the recurring findings. Cripple walls in that era were frequently unbraced, so seismic retrofit and crawl-space repair often belong in the same conversation. Newer construction on engineered footings shows less settlement, but drainage and flatwork issues still appear as lots age and downspouts route water toward foundations rather than away from them. Permits for foundation work route through Pierce County rather than Seattle SDCI, with different submittal expectations and review timelines. Confirming that before quoting avoids a scope priced to the wrong review path. We work across the plateau, the Lake Tapps edge, and the adjacent communities of Sumner and Buckley without changing the documented, plain-scope approach we use everywhere.
