Caulking Experts Proudly Serving Northcote, VIC Since 2019
Northcote sits roughly 5 kilometres north of Melbourne’s CBD, bordered by Fitzroy North, Thornbury, and Clifton Hill. It’s a suburb with genuine architectural variety, from Victorian-era workers’ cottages on Mitchell Street and Walker Street to mid-century brick homes on Separation Street and sleek new builds tucked behind heritage streetscapes. Our caulking services in Northcote, VIC are tailored to that variety, because a terrace home and a 1960s brick veneer need completely different approaches to sealing.
High Street is the spine of Northcote, busy, vibrant, and lined with the kind of buildings that need regular maintenance to stay watertight. We’ve worked on commercial tenancies, mixed-use buildings, and residential properties all along that corridor. Merri Creek runs along the suburb’s eastern edge, and properties near that lower-lying ground can experience more moisture and ground movement than the ridgeline streets, something our caulking specialist team factors in when recommending products and application methods.
Whether it’s sealing around the original timber sash windows in a Northcote Heritage Overlay property or applying waterproof window sealant to a recently built townhouse on Westbourne Grove, we bring the right knowledge and the right materials to every job. Northcote deserves caulking done with care and that’s exactly what Black Diamond delivers.
