How do you fix a vague scope of work before it becomes a dispute?

Work it through

You're the contractor. Pick what you'd do, then see how each choice plays out.

1. AStop before starting. Sit down with the homeowner, create a detailed scope addendum listing every material, fixture, and finish selection. Both parties sign before any demolition begins
   Correct

   A vague scope is a dispute waiting to happen. 'Renovate master bathroom' at $18K could mean anything from basic updates to a luxury remodel. Before swinging a hammer, nail down: (1) fixture brands/models, (2) tile selection with square footage, (3) tub — keep, replace, or convert to walk-in shower, (4) vanity style and countertop material, (5) lighting and electrical, (6) paint colors, (7) anything NOT included. Both signatures on the detailed scope prevent 'but I thought...' disputes.

2. BStart demolition and sort out selections as you go — that's how renovation works
   Terrible practice

   Once the old bathroom is demolished, the homeowner is captive. They can't use the bathroom until you finish, which gives you leverage but destroys trust. Every selection made on the fly risks: 'that's not what I wanted,' 'I thought that was included,' and 'this costs MORE?' Selecting fixtures and materials BEFORE demolition gives everyone clarity and prevents mid-project disputes.
