Double Bay is one of Sydney’s most prestigious harbourside villages, and Sterling Gasfitting & Plumbing has been servicing its homes, apartments and strata buildings for close to two decades. From the boutique-lined streets around Bay Street and William Street to the harbourfront apartment blocks near Double Bay Wharf, we know the mix of heritage housing and modern strata developments that make up this part of the harbour.

Plumbing in Double Bay

Double Bay’s property mix ranges from grand federation homes to newer luxury apartment developments, and we handle general plumbing repairs, blocked drains, tap and toilet repairs, and full bathroom and kitchen plumbing for both. Many of the older homes near Ocean Avenue and the surrounding streets still run original pipework that benefits from a professional assessment.

Hot Water Systems & Repairs

Whether it’s a standalone unit at a house or a shared plant room in one of Double Bay’s harbourside apartment towers, we install, service and repair all major hot water brands. Strata buildings here often run centralised systems, and we work directly with strata managers to keep them running reliably — see our full Hot Water Systems Sydney page for more.

Gas Fitting & Compliance

From new gas appliance installations to full compliance certificates for property sales and rental turnovers — common in a suburb with as much apartment turnover as Double Bay — our licensed gas fitters handle residential and strata gas work to Australian Standards. More detail on our Gas Fitting & Compliance page.

Leak Detection

Double Bay’s older buildings and harbourside apartment blocks can make hidden leaks tricky to trace — through heritage brickwork, under sandstone, or within shared strata risers. We use thermal imaging, acoustic listening and pressure testing to find leaks without unnecessary demolition. Full details on our Leak Detection Sydney page.

Heat Pump Installation

Heat pump hot water systems are increasingly popular with Double Bay homeowners looking to cut running costs on larger properties. We install and service heat pump systems for houses and strata buildings — see our Heat Pump Installation & Repairs page.
