1. Start with observation
Note the symptoms, limit additional damage where safely possible, and record the timing.
2. Evaluate the house and site conditions
Slow-draining clay till means standing water and drainage come first, followed by liner anchoring, termite-inspection access, air sealing against winter infiltration, equipment placement, and a look at the framing's condition.
3. Get a written scope
Detail prep, protection, materials, access, permits, testing, cleanup, restoration, exclusions, and change-order handling.
4. Weigh proposals against each other
Verify credentials and compare each bid's reasoning and boundaries, not just its total.
5. Confirm closeout details
Make sure testing, cleanup, documentation, and warranty terms are all covered before signing off.
