Basement Expert Services
Foundation waterproofing, structural repair, drainage, and restoration across Seattle, Snohomish County, and the Eastside — inspection-first, engineered for Puget Sound soils.
NDS-certified drainage & structural work
We design systems to move water off the structure and relieve hydrostatic pressure — exterior excavation, interior collection, French drains, and sump pumps scoped after a site visit.

Waterproofing & drainage
Keep groundwater and surface water away from your footing — the core of dry basements in Western Washington.
Foundation waterproofing
Exterior excavation, membrane, and footing-level drainage for Seattle, Everett, Bellevue, and Snohomish County.
Basement waterproofing
Interior and exterior approaches scoped to how water actually enters — walls, floor, or both.
Interior basement waterproofing
Sub-slab collection and sump systems when exterior access is limited or floor water is the main load.
Exterior basement waterproofing
Excavation, membrane continuity, and drain tile at the footing when wall leaks need to be stopped at the source.
French drain
Perimeter and yard drains designed with washed gravel, proper slope, and clear outlets — NDS-certified where specified.
Sump pumps
Replacement, backup power, and basin sizing for homes where the water table sits above the slab.
Crawlspace drainage
Engineering-grade drainage and hydrostatic relief — we do not offer encapsulation; we move water out.
Structure & repair
Cracks, movement, and wall stabilization — mapped and scoped after inspection, not guessed from photos.
Foundation repair
Crack injection, carbon fiber reinforcement, and structural stabilization across the Puget Sound metro.
Carbon fiber wall reinforcement
Stabilize bowing or cracked walls where excavation is not the first move.
Foundation crack repair
Active vs. dormant cracks, epoxy and urethane injection, and when monitoring is enough for now.
Restoration & remediation
After a flood, leak, or long-term moisture — dry-out, documentation, and repair coordinated with structural scope.
Water damage restoration
Extraction, structural drying, and repair after leaks, floods, or failed pumps.
Basement flood restoration
First response for wet basements — pump-out, dry-out, and path to permanent waterproofing if needed.
Mold remediation
Containment and removal tied to fixing the moisture source — not cosmetic cover-up.
Commercial water damage
Tenant spaces, multi-unit buildings, and facilities — documented mitigation for owners and managers.
