1. Observe and protect
Note where the issue shows up, what's nearby, and anything already tried — a few photos and measurements go a long way in the first call.
2. Evaluate the house and site
A good deck scope coordinates layout, setbacks, permits, foundations, framing, ledger flashing, stairs, guards, and material movement.
3. Define a written scope
Get the footing depth, material list, permit responsibility, cleanup terms, and change-order process in writing before anyone starts digging.
4. Compare providers
Read the reasoning behind each bid, not just the bottom line — that's usually where the real differences show up.
5. Inspect closeout
Walk the finished deck, confirm inspection sign-off happened, and get the warranty paperwork before final payment.
