O'Brien Plumbing & Roofing stands behind every job with a comprehensive workmanship warranty. Our guarantee covers labour and installation quality for all plumbing, roofing, hot water, gas fitting, and drainage work performed by our licensed technicians across the Central Coast and Northern Sydney.
We believe that a warranty should be simple, clear, and honoured without argument. If our work fails, we fix it — no excuses, no hidden conditions, and no cost to you.
We guarantee our workmanship for the lifetime of the installed product. This means that if a fault occurs due to our installation or repair work — whether that's a leaking joint, a poorly sealed flashing, an incorrectly wired hot water system, or a drainage connection that fails — we will return and rectify it at no additional cost to you, regardless of how much time has passed since the original installation.
This guarantee applies to all work performed by O'Brien Plumbing & Roofing technicians, including:
In addition to our workmanship guarantee, all products we install carry the manufacturer's warranty. Typical manufacturer warranty periods include:
We handle manufacturer warranty claims on your behalf and coordinate directly with suppliers for replacement parts or units. You deal with us — not the manufacturer's call centre.
All regulated plumbing, gas fitting, and drainage work is accompanied by the appropriate NSW compliance certificate. These certificates are your proof that the work was performed by a licensed tradesperson and meets the requirements of the Plumbing Code of Australia, AS/NZS 3500, and relevant gas standards. We lodge certificates with NSW Fair Trading and provide you with a copy for your records.

Services must be provided with due care and skill, be fit for purpose, and be completed within a reasonable time.
