About us

1954Started in the early 1960's by Eugene McMahon, Dernawilt Joinery has grown on the driving principle of quality in all aspects of the design and build process. We have a passion for using quality materials to produce quality products.


Our customers range from builders and developers to architects and private individuals, from as far afield as London, Belfast, Cork and many throughout the Dublin area. Projects both large and small are catered for, from new build and complete renovation to a single window or door.


DoorsAll types of window are manufactured with the ability to combine current insulation, ventilation and access requirements with a traditional style being a specialty. Sliding sash, casement and bay windows can be supplied, glazed and factory finished with preservative and primer ready for installation.



WindowsExternal doors including garage doors, fire rated doors and screens, in any design from arched entrance doors to a more traditional panelled style can be manufactured to your exact requirements in a variety of hard or softwoods. We can also supply ironmongery to complete.
