1. Observe and protect
Document symptoms, limit further damage where it is safe to do so, and collect relevant history.
2. Evaluate the house and site
House wrap condition, flashing at windows and trim, existing sheathing, and how a wall assembly manages moisture matter as much as the siding profile or color chosen.
3. Define a written scope
Clarify preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and change-order rules.
4. Compare providers
Verify credentials and compare the reasoning and boundaries behind each proposal, not only the total.
5. Inspect closeout
Confirm testing, cleanup, documentation, warranties, and remaining maintenance responsibilities.
