Oldstone Conservation was formed by in 2010 with the aim of providing a professional contracting service in the field of conservation and restoration.

Since its formation the Company has steadily grown and developed into a leading conservation contractor trusted to work on landmark buildings such as Leinster House, the General Post Office, Kilmainham Gaol, Belgard Castle as well as other historic buildings in Trinity College, Merrion Square and Henrietta Street.

We’re a small to medium sized business, which means there’s always a key player in our company involved with your project. It also means that we’re flexible enough to adapt to meet your needs. Despite our size we’re very well organised, and with the help of our multi-disciplined management team we can effectively manage projects both small and large as a main or specialist contractor.

We directly employ a range of specialists including stonemasons, bricklayers, lime renderers, facade cleaners & skilled conservation operatives. We take pride in our skilled and loyal staff, all of whom are highly experienced and enhance their knowledge on traditional building skills and techniques with every project completed..

Whilst we have grown in recent years we like to think we have managed to retain a warm and professional working environment, both for our clients and our employees.
