Scope and number of repair points
More support locations and more extensive structural work generally require more field time.
Access
Landscaping, hardscape, interior access, crawlspace conditions, utilities, and excavation constraints can affect the schedule.
Engineering and testing
Some projects involve engineering plans, plumbing tests, permits, or follow-up reviews that add steps before or after field work.
Ask about the full timeline
When comparing proposals, ask about preparation, field work, inspections, cleanup, and any work that occurs after structural repair.
