RJ O’Brien Building Contractors was founded by the late Ray O’Brien in 1969 (trading as Ray O’Brien Building Contractors).  A proud family business based County Cork, it is now run by his son John O’Brien.

We are a small-medium sized general building contracting company.  While much of our business is in the Cork and Munster area we operate a nationwide 24/7 service.

We specialise in project management and building maintenance in all trades from carpentry and decorating to electrics and plumbing to specialty trades as required.

Our work is predominantly based on commercial building, fit outs and building maintenance but we have vast experience in other areas ranging from new builds to renovations and conservation works

Fully insured and registered members:

We have a strong dedicated and loyal team that has been a major contribution to the success of our business over the years. We have the expertise, resources and personnel to undertake projects from small to large scale.

Our reputation is built on the highest level of quality and our commitment to provide industry leading building services to our customers. Our ability to meet challenges and deliver projects on time and within budget is reflected in our high levels of repeat business and our long-term client relationships.
