V Underpinning

For over a decade, V Underpinning (a V Build Company) has been reinventing Toronto’s foundations—literally. We specialize in precision basement lowering, walkout conversions, and emergency repairs, combining engineer-led techniques with heritage-conscious craftsmanship. Our laser-guided underpinning (0.5mm tolerance), lifetime waterproofing guarantees, and 97% permit approval rate make us the top choice for homeowners across the GTA—from The Beaches’ sandy soils to Rosedale’s heritage homes. Every project includes a free 3D design preview and is backed by our 15-year warranty—triple the industry standard.
