O'Connor Contracting were nothing short of exceptional. Quote very quick and they stuck to it. Timing was accurate and they even battled it out in the nasty weather. Staff were very hard working and great to chat with about the job, they clearly have great guidance and people skills. Design was completely what I dreamed of and then some. James O'Connor was consistent in his contact with me, yet took control of the project, and they ran with it. O'Connor Contracting have transformed my front entrance and my back yard beyond what I could imagine. On budget. 10 stars!

- Ann Shanahan

We hired James and his crew to do a new stone patio for us which was complicated by its location with relation to the septic bed. They were fast at getting us a hassle free quote and their momentum continued, resulting in a new patio completed before this summer has even begun. The workmanship is outstanding and there is clearly pride in what they do. The best part for me was how hassle free the experience was. This company is professional and knowledgeable and clearly prides themselves on accountability and integrity. We definitely recommend O'Connor Contracting.

- Melissa Swain

OConnor Contracting built a very large 1000sq ft patio for us, out of armor stone and interlock. At every step of the way, we were amazed! Their work is fantastic and his ideas and vision for our dream patio, were exactly what we wanted and more. We were always informed and felt at ease. They also delivered the entire project on time even with a few changes we made along the way. I would highly recommend James and his team for any stone project!!
