Read all our reviews"Chris and the team at BuildoReno were great to work with. They raised my ceilings and delivered quality structural work at a fair price, finishing the job quickly and efficiently. The final result was better than I expected and far superior to a similar project I had done years ago with another contractor. I would absolutely recommend them."

"Absolutely thrilled with our experience working with Buildoreno and we love our new backyard! From our initial meeting through to completion, Patrick, Chris and the crew were great to work with. Communicative, professional and they delivered on time, and as envisioned. We are already discussing and scoping our next project with them."
