Clontarf Homeowner

“We were able to watch J.Reilly Construction closely on another build before approaching them to quote on ours. The decision was easy because we knew they could offer us the best structural and environmental solutions and still maintain the design style we wanted. Once we agreed the fee we knew we were in safe hands.

“We contacted J.Reilly Construction to complete a large kitchen extension in August 2013. Jonathan has great insight and vision as to how you can maximise your property to its full potential. Jonathan’s attention to detail is excellent and was always on hand to communicate and query’s we had. Himself and the team made the process a very stress free one and we could not be happier with our extension. I would have no hesitation in recommending J.Reilly Construction for any future projects”.
