Questions before you swap a tub

  1. Is this a like-for-like swap, or does the drain move, and does that change whether we need a permit?
  2. Which of your licenses covers this: plumbing, or a remodeling license, or both?
  3. What does the new tub weigh, and does the floor underneath need any reinforcement?
  4. Was this house built before 1978, and if so, how are you handling any painted surfaces you disturb?
  5. Are you reusing the existing drain and overflow, or replacing that hardware too?
  6. What is the real difference in your price between refinishing, a liner, and a full replacement?
