Boiler Installation
O’Mahony plumbers power flushed our heating system when the radiators were not heating evenly or at all. The system is now vastly improved. The crew were very punctual, helpful and kept us informed of what was involved in the work. We found the price to be very competitive and would gladly recommend them to anyone looking for reliable plumbers.
