What dishwasher installation costs
A dishwasher install is priced by the visit, with the unit either supplied by you or added to the materials line. The nearest finished jobs on our list are the two shutoff valves replaced in Annapolis this October for $217 and a disposal swap in the same town for $265 with the unit. A dishwasher swap on clean lines lands in that same range of work.

What moves the price
- The lines under the sink decide most of it. A supply valve that holds and a drain with a working tailpiece keep the job to one trade and one visit.
- A hardwired unit adds the electrician for the connection, so the price shows two lines instead of one.
- A unit you buy yourself has no markup from us, but we need the model number first so the opening, the cord kit and the drain fitting match.
- Panel ready and built in European units take longer to fit and level, and we say so on the estimate.

Cost questions
- Do I need a permit to replace a dishwasher in Maryland?
- A like for like swap on existing lines does not need one in the counties we work. New drain or supply work does, and the plumber pulls it. Baltimore County and the WSSC parts of Montgomery and Prince George's have their own plumbing offices.
- Can you install a dishwasher I bought online?
- Yes. Send the model number with the address so we bring the right cord kit and fittings. We check the box for damage with you before the old unit comes out.
- What if there is no dishwasher there now?
- A first dishwasher needs a new drain connection, a supply valve and a receptacle, which is plumber and electrician work plus a permit. We quote it as one job with the trades named on the estimate.
