1. Observe and protect
Describe where the project is happening, roughly how big, and any drainage or grading concerns — that's enough detail to begin.
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
Put footing depth, materials, permit ownership, cleanup, and change-order terms in writing before ground gets broken.
4. Compare providers
Compare the reasoning in each proposal, not just the total at the bottom — that's usually where the real gap is.
5. Inspect closeout
Confirm inspection sign-off, walk the finished structure, and collect warranty paperwork before final payment goes out.
