We had Jon at O'Reilly Custom Homes work on a large Fire claim. They completed some framing at this home and the quality of work was very good.
- David S.
Had Jon and his workers come out and do a build for us and we’re very impressed with all of his attention to detail and quality products that he suggested... He was happy to explain why he was doing what he was doing whenever we had a question or concern... If anyone has any concerns feel free to contact me directly and I would be happy to elaborate on our amazing experience with O’reilly Custom Homes

Jon and his crew completed a custom build for us in 2022. Jon is excellent at communicating with his clients and is very knowledgeable. It was a pleasure to work with him and his team.

Jon has worked on two projects for my home in Millbrook. He built a fence in our backyard within a day and a half, and also built a deck/patio combo for us which is the nicest in the neighbourhood, very spacious. Highly recommend him!
