The best path depends on severity, local market, buyer expectations, repair quote quality, and whether an engineer report would reduce uncertainty.

FAQ
Can a vague foundation repair quote still be legitimate?
It might be, but it should be revised before signing. Ask for quantities, locations, materials, warranty terms, exclusions, and payment milestones in writing.
When should I get an engineer involved?
Consider an engineer when quotes conflict, the repair is expensive, there is active movement, walls are bowing, cracks are horizontal, or the contractor recommends major structural work.
