Deck Builders Sutherland Shire

Decking Built for the Sutherland Shire Conditions

The decking we install around the Sutherland Shire has to deal with sandy soils over Hawkesbury sandstone with clay pockets inland and with a wide spread from post-war brick to substantial waterfront rebuilds. Those two things between them explain most of what we recommend and most of what we advise against.

Most decking enquiries we take in the Sutherland Shire come from the same place: boards that have cupped and split after years without oil. It is worth understanding why that happens here before deciding what to replace it with.

Owners in the Sutherland Shire tend to call us at the point where patching has stopped working. By then the underlying issue is usually a substructure that has rotted where it sat in contact with damp ground, and a repair only postpones it.

Every quote we write for the Sutherland Shire comes from a site visit. Call 0492 879 796 and we will arrange one at a time that suits.

Local Conditions That Change the Job

Nothing about the Sutherland Shire is standard once you get past the front gate. We measure the whole site rather than the section you called about, because bushfire-prone land along the Royal National Park interface has a habit of turning up mid-job otherwise.

We allow for sandstone shelves that turn a routine hole into a rock-drilling job because it drives material selection more than aesthetics do. Specifying around it costs a little more once and saves replacing the job early.

One thing specific to this part of southern Sydney is salt-laden air off Bate Bay and Port Hacking that punishes untreated steel. It is easy to miss on a first look and expensive to discover once work has started.

Materials and Specification

Everything we install carries a manufacturer specification, and we install to it. Warranty claims fail on installation detail far more often than on product defect.

There is no premium in over-specifying something that was never going to fail. We put the money where the Sutherland Shire conditions actually attack the job, which is generally at ground level and at the fixings.

• Composite boards expand along their length more than timber, so end gaps are set differently.
• A deck is only as good as its substructure, and the substructure is what nobody sees when comparing quotes.
• Joist spacing is set by the board thickness and the direction of lay, and closing it up is what stops boards feeling springy.
• A deck built low to the ground needs ventilation underneath or the substructure will hold moisture and fail early.
• Merbau bleeds tannin for the first few rains, which is why a pre-coat before laying saves staining on light paving below.

Why the Sutherland Shire Owners Replace Decking

Decking in the Sutherland Shire is as much about access and set-out as it is about materials. On sandstone ridges and gullies falling to the Georges and Hacking waterways, getting the sequence right is what keeps a job to program.

• Boards that have cupped and split after years without oil
• Balustrade that no longer meets current height and infill expectations
• A springy feel from joists spanning further than they should
• A substructure that has rotted where it sat in contact with damp ground

Types of Decking for the Sutherland Shire Properties

Council Controls Worth Checking First

Heritage conservation, bushfire prone land and flood planning levels all sit on top of the standard controls in parts of southern Sydney. Any of the three can change what is permitted on a boundary.

Before anything is fabricated for a the Sutherland Shire property, we check what applies. Sutherland Shire Council publishes its controls, and heritage, bushfire and flood mapping can each change the answer entirely.

How We Approach a the Sutherland Shire Job

Rubbish and old material leave with us. Around the Sutherland Shire, dealing with sandy ground that drains beautifully but offers little lateral resistance makes storing a pile of demolition on site awkward for everyone, so removal is priced in rather than added later.

We stage the work so the property stays usable. On a boundary job that means a section is never left open overnight, and on a hard landscape job it means access to the house is maintained.

• Merbau and spotted gum hardwood decks
• Elevated decks with balustrade
• Composite and capped composite boards
• Low level decks over existing slabs
• Pool surround decking
• Hidden fixing and pre-oiled finishes
