Foundation cost in Seattle, WA
Foundation contractors correct settlement with piers, address drainage that caused the movement, and repair related cracking. An independent structural engineer's report is the single best money you can spend before hiring anyone.

Common questions
What are the real warning signs?
Doors that stick seasonally, stair-step cracks in brick, gaps at the top of interior doorframes, and sloping floors you can feel with a ball.
Do I need an engineer?
Yes. Get a report from an engineer who does not sell repairs, then get bids against that scope.
Things to watch out for
- Free inspections from companies that only earn money if you buy piers.
- Repairs that don't include correcting the drainage that caused the movement.
- Warranties that aren't transferable to the next owner.
