1. Observe and protect
Note when and where the problem appears, stop further damage if it's safe to, and keep records of anything tried already.
2. Evaluate the house and site
A useful evaluation weighs foundation type, pipe age and material, water pressure, and how the lot drains in Wilmington's flat, sandy terrain.
3. Define a written scope
Preparation, materials, permits, testing, cleanup, and exclusions all belong in writing before anyone starts work.
4. Compare providers
Compare the assumptions behind each proposal, not just the number at the bottom—different scopes aren't apples to apples.
5. Inspect closeout
Verify testing was done, the site was left clean, and you know what warranty and upkeep responsibilities remain.
