Foundation repair in Seattle, WA costs an average of $6,455, but it can range from $2,625 to $10,466, depending on your foundation type and the extent of the issue.


A higher cost of labor and an overall above-average cost of living make foundation repair in Seattle significantly more expensive than in other cities.
In addition to permit costs, Seattle homeowners may need to pay a sales tax rate of 10.40% for the labor needed for this project.
While prices for foundation repair in Seattle can be higher than average, homeowners do get some relief from the fact that the city's clay soil means most homes have pier and beam or slab foundations that are generally less expensive to repair compared to basement foundations.
