What Our Clients Say
Our new kitchen looks amazing, and it's much more functional for our family. Highly recommend Ace Build Contracting.
The team was professional, respectful of our home, and kept the site clean and safe. Communication was excellent—questions were answered the same day, and every change order was priced clearly before work proceeded. The craftsmanship really shows in the framing, drywall, millwork, and finishes, and the new layout from the addition flows perfectly with the original house.
We finished on schedule and very close to the agreed budget. If you’re considering a home addition or major renovation in the Burlington and the GTA, I highly recommend Ace Build Contracting. They’re reliable, transparent, and truly build with precision—the kind of contractor you can trust when you don’t have time to micromanage. Our house looks incredible and functions even better.
They were super professional, kept the place clean, and communicated well throughout the project. The design came out beautiful and modern, and the quality of their work really stands out. Everything feels solid, clean, and high-end.
If you want a basement done properly (and legally), Ace Build is the team to call. Highly recommend!
