I don’t know who built my house but it is a long way from compliant with building codes in the plumbing department. Our drains are regularly a problem and one lovely opportunity it has given us is a chance to try out literally dozens of plumbers in our area.
There’s only one we call now because the rest don’t really cut it for us. HP Plumbers Sydney are really intuitive about problems and they don’t come and consult with you on every decision. They make the calls and then come to you with the result, which is always a functioning drain.
For the work they do I think they are really reasonably priced and I’m always happy to pay for a job well done.
For blocked drains in Sydney you can’t go past HP Plumbers Sydney.
