Renovation Contractor in Oshawa & Durham Region
Serving Ajax & Durham Region
Custom kitchen renovations for Ajax homeowners, built by Mike Brock and the Cornerstone Construction team. One contract, a locked price, and a finished kitchen you will actually want to cook in.
Local Kitchen Builders
Ajax runs from the older lakeside neighbourhoods of Pickering Beach and the Hermitage up through Central Ajax and the newer family communities in Northeast Ajax and Audley. Across all of them, the kitchen is the room that dates a home first — closed-off layouts, builder-grade cabinets, and finishes that have seen better years. That is exactly the work we do, and we build kitchens for Ajax homeowners across the town.
Every Cornerstone kitchen runs on one contract and one point of contact. We handle the demolition, the structural work, electrical and plumbing rough-ins, custom cabinetry, counters, tile, and the final finish. You get a locked price before we start and a real-time portal to watch the project move. No subcontractor roulette, no surprise invoices — the same way we have built kitchens across Durham Region for years.
This page is part of our wider kitchen renovation service across Durham Region. Many Ajax homeowners pair the kitchen with a bathroom renovation in Ajax while the crew is on site, or turn the lower level into income with a legal basement apartment in Ajax. Browse finished kitchens and full home transformations in our project portfolio.
