Decking for Baulkham Hills properties, specified for Wianamatta shale clay that swells in a wet winter and shrinks back hard through summer and built by a licensed local team.
The decking we install around Baulkham Hills has to deal with Wianamatta shale clay that swells in a wet winter and shrinks back hard through summer and with 1970s and 1980s full brick homes on quarter-acre lots, many now carrying a second storey. Those two things between them explain most of what we recommend and most of what we advise against.
Owners in Baulkham Hills 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.
Most decking enquiries we take in Baulkham Hills 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.
Talk to us before you commit to anything. Call 0492 879 796 and we will tell you what your Baulkham Hills job actually involves, including the parts nobody enjoys paying for.
One thing specific to this part of the Hills District is battle-axe handles and shared driveways that decide how close a truck can park. It is easy to miss on a first look and expensive to discover once work has started.
Nothing about Baulkham Hills is standard once you get past the front gate. We measure the whole site rather than the section you called about, because clay that holds water against a footing long after the rain has stopped has a habit of turning up mid-job otherwise.
We allow for mature liquidambars and gums whose roots lift paving and push posts out of line because it drives material selection more than aesthetics do. Specifying around it costs a little more once and saves replacing the job early.
Every decking quote we write for Baulkham Hills starts on site, with photographs, levels and a walk of the full run. You cannot allow for cut-and-fill benching from the original subdivision leaving a hard step at the rear fence from a satellite image.
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 Baulkham Hills conditions actually attack the job, which is generally at ground level and at the fixings.
Raised decks with balustrade where the living floor sits well above the yard.
Galvanised steel or treated hardwood framing sized for span and for the ground beneath it.
Merbau, spotted gum and blackbutt boards, oiled and re-oiled to hold their colour.
Deck surfaces around a pool detailed for slip resistance and splash drainage.
Decks built low over an existing slab or paving where height is limited.
Transitions between levels set out so the rise is consistent and comfortable.
Our sequence on a Baulkham Hills job is the same every time: check services, confirm the boundary, set the footings out, cure properly, then build. Skipping the cure is the shortcut that shows up in year three.
Access is planned before pricing. On long side boundaries that fall steadily toward the rear of the block in Baulkham Hills, whether a truck can get close or whether everything is barrowed is the largest single variable in the program.
Most decks here are dealing with it. On long side boundaries that fall steadily toward the rear of the block, a deck is often the cheapest way to create level usable space, because the alternative is retaining and fill. The substructure carries the level change and the finished surface sits flush with the house floor.
The boards are rarely what fails first. On the sort of ground around Baulkham Hills, described as Wianamatta shale clay that swells in a wet winter and shrinks back hard through summer, it is the substructure and the connection to the ground that determines lifespan. Galvanised framing or treated hardwood on proper footings with ventilation underneath will outlast the deck surface by a wide margin.
Yes, and it is a good solution where a concrete area is sound but ugly. The build-up is kept low with battens or adjustable pedestals, and drainage across the slab has to be preserved so water still leaves. The one thing to watch is door thresholds, because the deck surface sits above the slab.
It depends on height and location. A low deck is often exempt development under the State Environmental Planning Policy for exempt and complying development, while a raised deck, or one close to a boundary, frequently is not. Heritage and bushfire mapping also change the answer. Check the specifics with The Hills Shire Council before you build.
Hardwood looks better and costs less to install, and it needs oiling to hold its colour. Composite costs more up front and asks for almost nothing afterwards. In Baulkham Hills, what usually tips the decision is mature liquidambars and gums whose roots lift paving and push posts out of line, because that determines how quickly an oiled surface breaks down and how often you would be back on your knees with a brush.
