1. Observe and protect
Note where on the lot you're picturing the deck, the general slope, and anything already tried — that's enough to start.
2. Evaluate the house and site
A good deck scope on East Tennessee's ridge-and-valley lots coordinates layout, footing depth on sloped or rocky ground, multi-level framing, ledger flashing, stairs, guardrails, and how the decking material will hold up outdoors.
3. Define a written scope
Get footing depth, framing spec, material list, permit ownership, cleanup terms, and change-order pricing in writing before any digging starts.
4. Compare providers
Compare the reasoning behind each bid, not just the bottom-line number — that's usually where real differences in footing approach show up.
5. Inspect closeout
Confirm any required inspection was signed off, walk the finished deck, and collect warranty paperwork before final payment.
