Renovation Contractor in Oshawa & Durham Region
From the established homes in south Pickering and the West Shore to the newer north Pickering communities, Cornerstone builds waterproof, built-to-last bathrooms — fixed price, daily cleanup, and a 5-year written warranty.
Local Knowledge
Pickering covers a real range of homes. The established south Pickering neighbourhoods — Bay Ridges, the West Shore, and the older areas near the lake — have homes with smaller original bathrooms and, often, older plumbing that needs attention once the walls are open. These spaces reward a smart redesign that makes a tight footprint feel modern and open.
In the newer north Pickering communities, the homes are structurally sound but the bathrooms are builder-grade — basic tile, entry-level fixtures, standard vanities. They're ideal candidates for an upgrade that adds comfort and value, and because the bones are solid the work goes straight into what you see and use.
Either way, the engineering underneath is what protects your home — and that never changes with budget. Every Pickering bathroom we build gets the same Schluter waterproofing system and a mandatory 24-hour flood test before a single tile goes in.
Plenty of Pickering renovations don't stop at the bathroom. If you're already opening up the home, it's the right time to fold in a kitchen renovation in Pickering while the trades are on site — and if you're finishing the lower level, a legal basement apartment in Pickering needs its own fully waterproofed bathroom built to this exact standard.

The Cornerstone Standard
Whether your Pickering bathroom is a focused refresh or a full ensuite, the structural standard never changes. Here's what goes into every one.
Schluter-KERDI-BOARD in all wet zones and Schluter-DITRA under every tile floor — water physically cannot reach your wall cavities or crack your tile.
Every shower basin is flooded to the brim and held for 24 hours before any tile goes in. If the water drops a millimetre, work stops.
A detailed multi-page proposal with a locked price and a committed schedule — backed by a $300/day penalty if we miss the end date.
Sealed dust containment, HEPA air scrubbers, floor armour, and a 30-minute cleanup every single day. Your home stays livable.
