Hey Plumbers

Need some genuine feedback on a stitch up

Had an emergency call out last night for a burst water pipe at my mums house

Was after hours (5pm) - fair enough, but just got the invoice from the plumber who has charged $280 for the call out free and first hour included, then $175 per hour for 2 hours labor plus $450 for the leak detection

However - didn’t fix the leak, found the leak almost immediately that it was in the shower behind concrete, turned water of at mains and advised he’d need to come back

All up, over $1k to find the leak was in the shower and turn off mains.

My mate said perhaps the labor is a bit inflated, but it’s double dipping with the “leak detection” at $450

Any genuine thoughts from some plumbers in here

Melbourne area

Cheers
