About Us

NKA Caulking has delivered clean, professional silicone work across Melbourne since 2013. In more than a decade we’ve completed 5 000 + jobs—from apartment towers and new-school builds to warehouses, factories and bathroom renovations.

At NKA we’re a tight-knit crew—small enough for strict, hands-on quality control, yet seasoned enough to handle anything from a single vanity seal to a 900-metre warehouse slab. Builders choose us for three things: reliability, competitive metre rates and expert knowledge in sealant selection and application. Because the same experienced NKA team stays on your project from start to finish—working to one documented set of company standards—you get consistent, neat, colour-matched caulking with the required silicone specified for each job specification.

What we specialise in

• New residential builds & multi-unit developments
  Duplexes, extensions & renovations

• Fibreglass-pool surrounds & outdoor wet areas

• Industrial joints, saw-cuts & large commercial slabs

Founded by Nathan Allan, NKA was built on one goal: be the final trade on-site that actually cares about the finish. Builders trust us because we show up, work clean and leave every job truly ready for hand-over.
