New Build

Often historic buildings require new adaptations for a number of reasons including accessibility and building regulation requirements.

We build using traditional techniques to ensure any new build adaptations are compatible with existing buildings.


At Clarke Restoration, our highly skilled team uses a wide range of specialised techniques including;

DOFF System Steam Cleaning

The DOFF system is a steam based stone cleaning system. It is not like any other steam system and it is able to reach temperatures of 150c at the nozzle end. The operator of the system is able to vary the temperature and pressure to remove either many types of paint or biological matter. All operatives are fully trained & accredited in the use of the Doff System. Using this method means no chemical biocides are required & pressure on the surface being cleaned is very gentle.

Brickwork and Stonework Pointing Northern Ireland

Brickwork Pointing and Stonework Pointing

There are numerous reasons for the building owner to commission the restoration of an existing building over the past two centuries.  The construction materials used tended to be of stone and brick.  All of which benefit from longevity.  Today there is a substantial percentage of aging buildings suffering from deterioration in the pointing element of the construction and will eventually lead to the poor performance of the building as a whole.

Repointing will aid with conservation, image and property value.

    • Infilling redundant service pipes and ducts

    Pressure pointing Northern Ireland

    Pressure Pointing

    Pressure can be carried it using hand held pointing guns or by a machine pumping the mortar through a hose with a hand control valve. It is ideal for the replacement of water eroded or defective joints which have being raked out and ready for the application.

    Pressure pointing enables the new joints to be installed quickly and consistently with good compaction and ensuring a complete fill of the void.

    The mortars are normally pre–bagged so a consistent colour can be guaranteed and can be applied in overhead situations such as vaulted arches, culverts tunnels etc special lime blends can be used for heritage or listed buildings.
