Hi Melbourne business owners, running into a bit of a nightmare at our commercial office/warehouse space in Richmond. Over the last couple of weeks, we noticed a weird damp patch forming near the structural concrete column, and our main water meter is slowly ticking over even over the weekend when no staff are on site. Since it's a commercial lease, we can't just go around cutting into walls or jackhammering the floor without exact proof for the landlord and insurance. Does anyone have experience with reliable water leak detection melbourne specialists who handle commercial properties? We need someone with advanced non-destructive equipment who can isolate the source quickly so we don't have to interrupt our daily business operations or face massive repair costs later down the track.
