1. Note the problem
Write down what the system is doing, snap a few photos, and limit further damage where that's safe, so a minor issue doesn't turn into a larger repair.
2. Assess the house and site
Whether it's a nineteenth-century in-town home or a newer subdivision house, the right scope starts with how that specific property was built and graded, not a checklist copied from somewhere else in the county.
3. Get the scope in writing
Spell out preparation, protection, materials, access, permits, testing, cleanup, finish work, exclusions, and how change orders are handled.
4. Compare the proposals
Check credentials first, then compare how each provider reasons through the job, not just which number is lowest.
5. Confirm the closeout
Make sure testing, cleanup, paperwork, warranties, and ongoing maintenance responsibilities are all settled before the crew leaves.
