Drilling is in our genes. Our family has been doing it for almost 100 years.
During that time we have gained valuable experience in the various types of drilling needed in Ireland, perfecting our process, regardless of the type of Irish terrain and sub-terrain we encounter.
We are proud of our long standing tradition, however, we are aware we are only as good as our last job. We strive to give the best possible service to all our customers.

Genuine Customer Feedback
“I was very happy with the timeframe of which Dempsey’s were able to complete the project. They drilled 2 geothermal bore holes, a water well, supplied and fitted the pump and treatment system.”
