1. Observe and protect
Capture the symptoms, limit further damage where safe, and note whatever relevant history exists.
2. Evaluate the house and site
Roof area, valleys, tree debris, fascia condition, downspout placement, and the final discharge point matter more to long-term performance than gutter color -- especially where a poorly discharged downspout can feed straight into a crawl space or karst-prone soil.
3. Define a written scope
Spell out preparation, protection, materials, access, permits, testing, cleanup, restoration, and exclusions clearly.
4. Compare providers
Confirm credentials and weigh the reasoning and boundaries in each proposal, not just the number quoted.
5. Inspect closeout
Verify testing, cleanup, paperwork, warranty terms, and remaining maintenance responsibilities.
