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.

Nothing is committed until you have the written scope in front of you. 1. 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. 2. 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. 3. 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. 4. 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. ## Need a foundation opinion in Kenmore? Send the observations and the address.

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 Illustrative summaries of the service experience.

Local knowledge ## King County Review and Lake Shore Access Foundation work in Kenmore routes through King County Development Services rather than a city building department. Submittal requirements and review timelines differ from those of incorporated municipalities to the south and east, and confirming the applicable authority is part of scoping a project here rather than an assumption made after quoting. Parcels near the Bothell or Shoreline city boundaries can fall under a different jurisdiction, and we identify the correct department at the start. Access across most Kenmore lots is generally workable. Shoreline-adjacent parcels along the lake can have steeper grades above the waterfront and limited turnaround for larger equipment. Where retaining structures or mature landscaping constrain access on hillside lots above the lake, we assess those limitations during the evaluation and note them in the written scope before work begins. Crews reach Kenmore via SR-522 as part of our regular north King County coverage alongside Bothell, Shoreline, and Kirkland. We schedule work efficiently rather than treating the area as a distant assignment with uncertain arrival windows. ## Post-War Homes and Lake Corridor Moisture The dominant housing type in Kenmore runs from post-war and mid-century construction in the Wayne and Moorlands neighborhoods to newer subdivisions in Arrowhead and the Northshore corridor. Older homes from the 1950s through the early 1980s sit on conventional crawl spaces with post-and-pier supports, perimeter stem walls, and sill plates that were 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. The lake corridor and low-lying ground near the shoreline keep crawl spaces wetter than inland properties of the same vintage. Where the terrain rises toward the hillside subdivisions above the lake, drainage routing and slope considerations shape the scope. Runoff from uphill streets can concentrate at foundation walls through the wet season, and interceptor drainage uphill of the structure often accomplishes more than anything installed at the footing line. Newer construction in Arrowhead and the Northshore area sits on engineered footings with more predictable bearing conditions. Settlement is less common there, but drainage and flatwork issues appear on these lots as downspouts route water toward foundations and driveways settle over years of wet winters. We record what we observe on your specific lot rather than applying a subdivision-wide assumption to any part of the coverage area. ![Older Pacific Northwest residential street of timber-frame homes on a gentle slope](/images/misc/older-pacific-northwest-residential-street-of-timb.webp) Neighbourhoods covered Wayne Moorlands Arrowhead Downtown Kenmore Northshore Permitting authority King County Requirements differ between jurisdictions.

Yes in most cases. Structural foundation work generally requires a building permit, and Kenmore parcels route through King County Development Services rather than a city building department. Parcels near the Bothell or Shoreline city boundaries may fall under a different jurisdiction. We confirm the applicable authority before quoting so the review path in your scope is accurate. My home near the lake has a wet crawl space every winter. What causes that? Near the Lake Washington shoreline, elevated seasonal groundwater and surface runoff from uphill lots can keep crawl spaces saturated through the wet season. The fix involves identifying the pathway, collecting water with a properly sized sump, and routing discharge away from the property rather than back into the same ground. My older home has sloping floors. Is that a foundation problem? In most homes of the 1950s to 1980s 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. 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. How do I get started?
