I have worked with O’Neill Development for over twenty years on both new homes and renovations. By every standard – quality of workmanship, timely completion of work, and service after completion – they are at the top of the list. Because of that and because of the quality of of their job superintendents and subcontractors, they have become our go-to partner in all of our high performance and Passive House projects.
