1. Observe and protect
Note where on the lot you're picturing the build, roughly how big, and any drainage concerns — that's enough to start.
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 footing depth, materials, permit ownership, cleanup, and change-order terms in writing before work starts.
4. Compare providers
Compare the reasoning in each proposal, not just the bottom-line total — that's usually where the real gap is.
5. Inspect closeout
Confirm inspection sign-off, walk the finished deck, and collect warranty paperwork before final payment.
