1. Get the facts down first
Note when the issue started, whether it lines up with a storm, and what the home's rough construction era is.
2. Factor in the site conditions
Grading around older mill-district homes, clay soil, and newer-subdivision drainage patterns all change the plan.
3. Require a scope in writing
Preparation, materials, permits, testing, and change-order terms should all be spelled out before work starts.
4. Line up competing bids
See how each provider reasons through the same drainage and access issues, not just their price.
5. Check the finished work
Confirm cleanup, documentation, and warranty terms before calling the project done.
