Seahurst sits on a bluff above Puget Sound, so water here comes from three directions: runoff down the slope, groundwater into crawl spaces and daylight basements, and old drain lines that back up. Seattle Water Damage Restoration answers phones 24/7 and sends a technician the same day when one is free.
Seahurst is a residential community on the bluff above Puget Sound, on the south side of Burien and south of Seattle in King County. Seahurst Park's beach and Miller Creek run through it, and Ambaum Boulevard and 1st Avenue South are the roads most people use to get in and out.
The houses are largely single-family homes from the 1950s to the 1970s, and many have a crawl space or a daylight basement. Neither is bad in itself. Both are the places in a house that a wet winter finds first.
This page is about the local pattern of damage. If water is on your floor right now, skip to the section on bluffs and slopes, then call.
Winter atmospheric rivers, long soaking fronts from October to March, saturated slopes decide which water problems are most likely in Seattle from week to week.
A bluff above the Sound sheds water fast and holds it in odd places. Rain runs toward the edge, soaks into soil that is already saturated by midwinter, and then the downhill side of a foundation takes the load. Steep bluffs and winter rain also make slope movement a local concern, so signs such as leaning fences, new cracks in a patio or a door that suddenly sticks are worth reporting.
When water gets inside, it usually arrives low. The first sign may be damp carpet in a downstairs bedroom on the uphill side, or a wet strip along the base of a wall. A technician starts by tracing the pattern, because water entering through a wall leaves a different map from water rising through a floor.
If you suspect movement, leave first and clean up later. Once the slope is judged stable, emergency water removal can start.
A practical habit: after each hard rain, walk the downhill side of the house and the base of the bluff-facing wall. Look at the soil, the gutters' discharge point and the edge of the patio. A new damp patch or a pool that did not used to form is more useful to a technician than any guess about the cause.
Many Seahurst homes sit over crawl spaces, and a wet winter turns them into shallow catch basins. Standing water, sagging insulation, a vapor barrier pushed aside by ground heave and vents that let in damp air are all common after months of rain. The floor above stays cold and may smell musty before anything looks wrong.
Crews enter in protective gear, pump standing water, remove saturated insulation and set air movers and dehumidifiers to dry joists and subfloor. Mold risk rises the longer wood stays wet, which is why crawl space water damage is better dealt with in weeks than in seasons.
King County maps flood-prone stretches along Miller Creek and Walker Creek. If your house is near either, rain-swollen water and street runoff can reach lower rooms, and that water is Category 3, which means carpet and pad are removed and hard surfaces disinfected. Flood needs its own insurance policy.
Separate from the creeks, older drain lines and root intrusion are a common cause of backups. A slow floor drain or a toilet that gurgles after the washer runs is the warning. Sewage cleanup involves removing soaked wallboard quickly and disinfecting what stays; see sewage cleanup.
Do not wait to see whether a backup clears itself. SPU's guidance on sewage-soaked wallboard is to remove it within 24 hours, and the same logic applies on the Seahurst side of the line: the longer sewage sits in porous material, the more of it has to be discarded.
Expect equipment in the wet rooms for several days. Cool, humid winter air slows drying, so dehumidifiers matter more than fans. The technician returns to take readings, moves equipment as areas dry and removes it only when wood and drywall read dry.
Keep doors to the drying area closed, leave the equipment on and do not stack boxes against wet walls. A bill for the work should list equipment days and materials removed; ask for the price in writing before the job starts, since national averages are not local figures.
Seahurst Park's beach and its surrounding slopes are a neighbor to many of these homes, and drainage from one lot flows onto the next. A downspout tied to a neighbor's pipe, a driveway that sheds onto your side yard or a French drain that outlets onto the bluff can all move water in ways nobody planned.
If you find water crossing a property line, take photographs and talk to the neighbor early. It helps a technician to know whether the wet area is a one-lot problem or part of a shared drainage path. The crew documents your side and leaves legal responsibility to the people involved.

Open the access hatch with a flashlight, wearing gloves and a mask. Look for pooled water, dark insulation lying on the ground and a damp, earthy smell. If you see standing water, do not enter while it is deep; a technician can pump it and photograph the space.
It can be both. Water finding its way under concrete is a common precursor to movement, and a cracked slab with a wet crawl or basement nearby deserves a closer look. If you see shifting, ask a geotechnical professional, and tell the technician.
Usually not. A standard homeowners policy typically excludes flood, which needs a separate NFIP or private policy. Check your declarations page and ask your agent whether you have one.
In most cases yes, for rooms not affected. Dehumidifiers and air movers are loud and warm, and the wet area is sealed off. If sewage was involved, stay out of the affected zone entirely.
Water appearing at a floor drain, a shower or the lowest toilet during heavy rain or washing-machine use points to the drain line. Stains on ceilings or high on walls point to the roof. Tell the technician which, because the cleanup differs.
