Handyman or licensed pro?

A like-for-like swap on existing water, drain and power is common handyman work in many places. A new circuit needs an electrician and new supply lines may need a plumber, depending on your state. Rules vary by state; see handyman license requirements by state.

How to quote it

Ask for photos under the sink and of the old unit's connections.
Include a new supply line and drain hose in the quote; reusing old ones causes leaks.
List haul-away separately.
