Your estimate
What is included in the plan.
Repair the cause
New lumber will not stay sound if standing water, a plumbing leak or uncontrolled humidity remains.
Permanent bearing
A new post needs an adequate footing and secure top connection; a jack on soil or a loose block is not a finished repair.
Movement above
Raising a floor can crack finishes and stress utilities. The plan should state whether the goal is stabilization or correction.
Access
Low clearance can change materials, sequencing, equipment and cost.

Common questions
Crawlspace Structural Repair FAQs
These answers cover the questions homeowners ask most often. Your inspection and written estimate will address the conditions at your home.
Will adding floor jacks fix a sagging floor?
Only if the jacks, footings, beam and connections are properly designed for the load. Adjustable columns can be part of a permanent repair, but temporary posts on poor bearing are not enough.
Can a sagging floor be made level again?
Sometimes it can be improved gradually; in other homes, stabilization is safer than a full lift. The amount of movement, age of the condition, finishes and utilities affect the decision.
Should encapsulation happen before structural repair?
Active water should be controlled before new structural materials are installed, but sequencing varies. Structural access may be easier before the final liner is fitted.
