I have used these guys twice in the last 6 months, once just for basic stuff but recently we had our bathroom renovated. The young plumber was fantastic, he installed a vanity, toilet and laundry trough with no hassle at all. He informed us of a dodgy downpipe that wasn't connected properly(not surprising, last owner was a shonky do it yourselfer) and rectified problem. At the end, he took all old fittings and rubbish away for free, and was friendly, polite and efficient. I have no worries recommending these guys and continue to use them in future.
We have had work done by J & C Overeem plumbing.
We were very dissapointed. The bill was huge ( $85.00 per hour and materials) and the work done was hopeless. They send out an apprentice to do the work and if you make a comment that the job is only half done you never hear from them again. They do not check the apprentice job and any feedback they prefer to ignore. For 85 dollars per hour I know better plumbers that take pride in their work!! I would certainly not recommend them to anyone!
