Bathrooms taps were making a whistling noise so I wanted that fixed, and decided to get washers on other taps changed at the same time.
After a couple of days, we were unable to turn off some taps, as they were dripping.
I contacted them to complain, but they were not very helpful or eager to come & fix it.

Approximate cost: $150

Adam was the plumber we had when our new kitchen was installed. He did the tap connections, dishwasher and gas cooktop connection. He was the contractor used by the kitchen company we had for a kitchen. His cost was built into the overall cost of the kitchen so we cannot comment on value.
