Require urgent water leak repair in home in Ireland

I'm looking for a skilled tradesperson to repair a water leak in my home. The issue seems to be a dripping pipe under the kitchen sink and a damp patch along the wall near the bathroom. I need someone who can locate the source, shut off the water safely if needed, and fix or replace the faulty pipe or fitting. Please include a quick assessment, any parts you expect to bring, and a clear estimate of costs. Access is straightforward, and I’d prefer someone available this week. Basic safety precautions and a tidy cleanup after the repair are appreciated.
