Our engineers know the full range of plumbing systems found in local properties — from Victorian terraced houses with ageing lead or iron pipework and original cast iron radiators to modern apartments with combination boilers, underfloor heating and contemporary bathroom fittings. That knowledge means we suggest the right repair approach and arrive with the correct materials and parts for your specific plumbing fault the first time.
Every job is carried out by a fully Gas Safe registered, insured engineer — not a subcontractor or apprentice. We arrive on time, give you a fixed price before we begin, and do not leave until all repaired systems and fixtures have been fully tested and confirmed working. Our work is fully insured and backed by our 12-month workmanship guarantee.
From one-off repairs in flats to full central heating installations in larger family homes, we handle every type of plumbing job. We also cover surrounding towns and villages — get in touch if you are unsure whether we reach your specific postcode.
Same day plumbing
If your boiler has stopped working, your drains are blocked, or a burst pipe is causing damage, same-day emergency slots are available. Contact us and we can usually have a local Gas Safe registered engineer with you the same day.
Common plumbing faults
Not every plumbing problem requires a full replacement or expensive renovation. Dripping taps, burst pipes, blocked drains, low boiler pressure, loss of heating, hidden water leaks — each points to a specific, often straightforward repair. Our engineers assess on-site and give you a straight answer before any work begins. We only recommend replacement when repair is genuinely not cost-effective.
Landlords and letting agents across Northern Ireland rely on us for fast, documented plumbing repairs and annual landlord gas safety certificates (CP12). We provide written confirmation of all work completed and our workmanship guarantee — everything you need for your property records. Priority scheduling is available for rental properties.
