I'm having a drainage issue in my home and need an experienced handyman to clear a blockage in both the kitchen sink and one bathroom drain. The kitchen sink drains slowly and sometimes backflows when I run water. The bathroom drain is occasionally slow too. Please bring proper plungers, augers, and any professional equipment to ensure a lasting fix. I'm looking for a clear assessment, no-dig solutions if possible, and advice on preventing future clogs. Availability this week is best in the mornings, and I prefer a tidy, respectful handyperson who can explain what caused the blockage and how to avoid it. Irish plumbing standards and any necessary safety precautions should be followed.
