What do you owe a client in an after-hours warranty emergency?

Work it through

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

1. AWalk them through shutting off the water supply valve immediately. Schedule a visit first thing in the morning. This is a warranty issue you need to address
   Correct

   Emergency response is part of being a professional contractor. You don't need to be on-site at 11 PM, but helping them stop the water damage by phone is the right first step. The leak is likely a warranty issue — a fitting failure or connection issue from your renovation. Schedule the morning visit, document everything, and fix it under warranty. This kind of responsiveness generates lifelong clients.

2. BTell them to call a plumber — you're not on-call for emergencies
   Poor response

   If your renovation plumbing is leaking three months later during your warranty period, that's YOUR responsibility. Telling a client with an active flood to call someone else is how you lose clients, generate complaints, and build a reputation as a contractor who disappears after final payment. At minimum, help them stop the water by phone. The plumbing you installed is failing — own it.
