I have worked with Drumcilla Construction over the past 5 years or so on several mid-size complete refurbishment and extension projects around south County Dublin as well as a new 250 sq m contemporary house in Blackrock. From the first project I have been impressed with their professionalism, attention to detail, knowledge of all trades including new technologies and careful pricing. Through their friendly disposition Peter and Noel with their own team and subcontractors gel well together to produce a high standard of work. They are on my preferred contractors list ever since we first met.
