What drives the price of foundation repair in Seattle
Two foundation repair companies can quote the same job and land hundreds of dollars apart, because the price is set less by the company than by the work itself. For foundation repair, the factors that move the number most are:
- The type, from slab to pier-and-beam.
- The number of piers needed.
- Drainage and waterproofing.
- Engineering reports and permits.
Before you compare quotes, write down your version of each of these. When every foundation repair companies prices the identical scope, the cheapest bid is finally a real deal rather than a different, smaller job in disguise.
