RESIDENTIAL CAULKING
Whether it's a brand-new build, a top-to-bottom renovation, a compact unit, or a spacious duplex, we handle every caulking line your project demands—whenever you need us. Mid-construction, while scaffold's still up, we seal brickwork, render, and external gaps to keep the structure weather-tight. Closer to hand-over, we protect bathrooms, kitchens, laundries, and other wet areas, then finish skirting boards, architraves, window frames, and door jambs with the same crisp, colour-matched bead. Every joint is laid with premium sealants from industry-leading European and Australian brands, applied using streamlined techniques that deliver razor-sharp lines, long-lasting flexibility, and mould resistance—keeping your home flawless for years to come.
POOL CAULKING
We specialise in fibreglass pool caulking, coping joints, and paver sealing. With our signature dry-sticking technique, we tool a generous, colour-matched, natural-stone-safe, UV-stable silicone bead entirely without water, preventing overspray from seeping into the joint and compromising the seal before it cures. The result is a clean, flexible joint that shrugs off pool chemicals and harsh outdoor conditions—no smearing, no cracking, just a seamless finish that keeps your pool watertight and picture-perfect for years.
COMMERCIAL CAULKING
From warehouses and factories to retail, hospitality, and gym fit-outs, we handle commercial caulking at any scale—quickly and to spec. Our team seals factory-floor saw-cut joints and topping-slab expansion joints, caulks bare slabs before epoxy coatings, and seals precast panels, tilt-ups, and fire-rated penetrations. We work around tight shop-fit schedules, including after hours, to finish bathrooms, kitchens, facades, and trims exactly when the build needs it. Using proven, industry-leading products, we deliver clean, reliable joints that last.
