The craftsmanship is excellent—the kitchen is beautiful and functional, the bathroom feels like a proper upgrade, and the basement went from a dusty storage zone to a bright space we actually use every day. There were a couple of minor material delays along the way, but they communicated immediately and sorted it out without dragging their feet.

We recently hired Proventa Construction for a complete overhaul of both our kitchen and bathroom, and honestly, they… knocked it out of the park. From our very first meeting, the team felt more like good neighbors who genuinely cared about our house rather than just another contractor. They really listened to our vision (and our budget!) and turned what could have been a super stressful process into a really exciting project. The craftsmanship is top-tier. Our kitchen is now the ultimate gathering spot—functional, beautiful, and the custom finishes are just stunning. And the bathroom? It honestly feels like a boutique hotel spa now. What really stood out to us was their communication. They kept us in the loop every step of the way, showed up on time, and left the place spotless at the end of every work day. In true Canadian fashion, they were polite, professional, and just a real pleasure to have around.
