Caulking in the Hills District: where we work
Yes, the area is covered. Australian Caulking Experts provides caulking in the Hills District as part of our Sydney-wide coverage. The district lies north of Smithfield, where our base is.
The Hills District is a region, not a single suburb. On this page it means suburbs of The Hills Shire such as Baulkham Hills, Bella Vista, Norwest, Kellyville and North Kellyville, where the council has redrawn suburb boundaries around the Norwest, Bella Vista and Kellyville stations of the Sydney Metro Northwest. Rouse Hill, next to Kellyville, has its own page.
Growth around the Metro Northwest
The Hills Shire Council made those boundary changes in response to release area development in North Kellyville and to new development planned around the metro stations. Each type of building brings its own caulking scope:
- New houses: wet areas, kitchens, skirting and floor joints, and window and door perimeters, as covered by caulking for new homes.
- Townhouses and duplexes: the same internal scope repeated across several dwellings, plus facade and window junctions on each one.
- Higher-density buildings near stations: unit wet areas, facade joints and fire-rated sealing to penetrations where it is specified.
Fitting caulking into a new-home build
Caulking is one of the last trades through a new house, and timing it badly means sealing next to wet paint or under other trades' feet. On a typical build the order runs:
- Tiling, stone benchtops and joinery are installed and grouted.
- Painting is finished, or at least the surfaces next to sealant joints are.
- Internal caulking goes in, room by room.
- The sealant is left to cure before cleaning, fixtures or handover.
Curing time depends on the product, joint depth and conditions; our article on caulking curing times explains how to plan other trades around it.
Established homes and re-caulking
Not every request for caulking in the Hills District is for a new build. In older houses, typical requests are a shower or bath whose silicone has gone mouldy or lifted, a kitchen splashback joint that has cracked, or window perimeters that have shrunk away from the frame.
Those jobs fall under remedial caulking: the failed sealant is removed rather than covered, and the replacement bead is coloured to blend with what surrounds it. Our residential caulking service also takes in joinery, wardrobes and stonework in renovated homes.

Frequently asked questions
Can you price caulking from house plans before construction starts?
Yes. We can quote from architectural plans or takeoffs, which suits builders working through a new estate or a run of townhouses. New builds and packages are typically priced by the lineal metre, and larger residential projects can be set at a tailored metre rate or package based on volume and access.
Do you work on townhouse and duplex projects?
Yes. Our residential work covers houses, townhouses, duplexes and apartment developments, from a single-room fit-out to full internal and external packages. On multi-dwelling projects each home gets the same attention, and colour-matched sealants keep the finish consistent from one home to the next.
Will re-caulking stop a leaking shower?
Only if the sealant joints are the problem. Caulking seals the visible joints between tiles, screens, trays and walls, but waterproofing is a separate trade: the membrane behind the tiles is what protects the structure. If water is getting past the membrane, a waterproofer needs to assess it first, and the shower can be resealed once that is fixed.
Why does shower silicone go mouldy, and can it be cleaned?
Mould grows where moisture sits on or in the sealant, which is why wet areas need a sanitary sealant formulated against mould and mildew. Surface marks can sometimes be cleaned, but once mould has grown into the bead itself it usually needs to be cut out and replaced.
