1. Observe before anything else
Write down the symptoms, limit further damage if it's safe to, and gather whatever history is available on the home.
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. Write the scope down
Preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and change-order terms need to be explicit.
4. Weigh your options
Check credentials, then compare the reasoning and boundaries in each proposal, not just the total price.
5. Confirm before calling it done
Testing, cleanup, documentation, warranty paperwork, and remaining maintenance duties should be confirmed at closeout.
