Glass pool fencing and balustrades in Mosman

Most Mosman pools sit on a terrace somewhere down a slope, with the harbour beyond, so frameless glass on spigots is the usual choice. The hard part is the levels. Every panel has to stand at least 1200 mm above the ground outside it, and any new barrier must meet AS 1926.1-2012.

Updated 24 October 2026

A Mosman pool fence is usually a fence on a staircase. The house sits up the hill, the pool is cut into a terrace below it, and the garden keeps falling towards the water. Each of those level changes is a place where a fence can come up short.

Setting out on a slope

The rule is simple to state. The glass has to be at least 1200 mm above the finished ground on the outside, measured wherever a child could stand. On a flat courtyard that’s one number. On a terrace with a garden bed dropping away below it, the measurement changes every few panels.

We handle it in one of two ways. Stepped panels sit level and drop at each post or spigot, which looks tidy and keeps standard sizes in play. Raked panels are cut to follow the fall in a straight line, which looks cleaner on a long run but means every panel is made to order. On most harbour terraces we end up with a mix.

The fixing depends on what’s underneath. Where the terrace is concrete or sits on sandstone, spigots are core-drilled straight in, leaving only a small round fitting at the base of each panel. Where the edge is a garden bed or a retaining wall top, we may need a footing or a side-fixed spigot instead.

Keeping the view

People in Mosman choose glass for the view, so the fence shouldn’t take it back. Frameless panels on spigots have no posts to look past. A recessed channel hides even that, though it has to be built into the slab, so it suits a new terrace better than an existing one.

If the house has a deck or balcony looking over the pool, it can take the same glass as a balustrade. The two are separate barriers with separate rules. A balustrade needs to be at least 1 m high where the fall is 1 m or more, and a pool fence needs 1200 mm, so the heights won’t match exactly.

Salt air and the hardware

The glass doesn’t care about salt. The steel does. Close to the harbour, cheaper stainless picks up rust spots quickly, so we fit marine-grade or duplex spigots and hinges. Ask about it on any quote you compare, because the grade is easy to leave off.

Before you book

Mosman Council runs a pool barrier inspection program, and you can apply to Council for a certificate of compliance or ask them to inspect. An accredited private certifier can do the same. Replace an old fence with glass and the new barrier has to meet AS 1926.1-2012, whatever age the pool is.

Common questions

Who inspects pool fences in Mosman?

Mosman Council runs a pool barrier inspection program. You can apply to Council for a certificate of compliance and have Council do the inspection, or use an accredited private certifier. You need a valid certificate, or one of the other accepted documents, to sell or lease.

What hardware suits a harbourside Mosman home?

Marine-grade or duplex stainless spigots and hinges, or powder-coated aluminium. Salt air marks lower grades of stainless quickly. A rinse with fresh water every so often keeps the better grades clean.

Can you fence a pool on a steep Mosman block?

Yes. The panels step down with the ground, or are cut on a rake, so the fence stays at least 1200 mm high on the outside along the whole run. Odd sizes are toughened to order, which adds lead time.
