A bathroom leak rarely shows where it starts. Wastes, traps, tray seals and supply joints all drain to the same ceiling stain below. Our Belfast engineers test-isolate each in turn, then fix the real one.

Belfast water notes: Belfast's supply from the Mournes and Antrim hills is soft — scale is a minor factor, and the workload tilts toward the city's older terrace pipework, winter freezes and conversions. Belfast's parlour terraces off the Ormeau, Lisburn and Antrim Roads carry early-1900s plumbing bones, alongside postwar estates and the Titanic Quarter's modern apartment blocks. Mains supply here is managed by NI Water.

Small works: the everyday bathroom list

The routine calls across Belfast: bath wastes leaking into the ceiling below, basin traps that were never quite tightened, mouldy failed silicone lines masquerading as mystery leaks, toilets running to the pan, and sanitaryware swaps where the old fittings have seized. Small, defined jobs — fixed same-visit with stocked parts wherever access allows.

Refits: first fix and second fix

First fix is where a bathroom is won or lost: supply and waste pipework routed to the new layout with correct falls on wastes, isolation valves on every feed, pipe runs pressure-tested before anything is boarded over. Second fix — connecting and commissioning sanitaryware, brassware and wastes after tiling — is where the finish quality shows. We take either stage or both across Belfast, working alongside your tiler and fitter or supplying the full wet-side scope.

Finding bathroom leaks properly

Bathroom leak diagnosis is sequencing: static supply joints first (they leak constantly), then each waste under flow, then seals under spray. The method matters because the fixes differ by an order of magnitude — a trap washer versus a tray reseat. Our Belfast engineers test before they quote, so you're paying to fix the leak you actually have.

Bathroom plumbing costs in Belfast

Small works from £99 with standard parts included. Sanitaryware swaps are fixed-quoted per item. Refit wet-side scopes are priced from the layout drawing or a site visit — first fix and second fix itemised separately so you can stage the spend. No Belfast job starts without an agreed figure.

Frequently asked questions

My bath drains slowly but the sink is fine — why?

Localised slow drainage points to that fixture's trap and branch — hair and soap build-up usually. If several fixtures slow together or gurgle, the issue is downstream in the shared run or external drains, which we route to our drainage partner honestly.

Do you fit bathrooms supplied by a showroom?

Yes — we take the wet-side scope (first and second fix) alongside your fitter or showroom installer, and coordinate sequencing with tiling. Sanitaryware is checked on delivery before the old suite comes out.

What's the difference between first fix and second fix?

First fix is pipework to the new layout before walls and floors close — the structural plumbing. Second fix is fitting and connecting sanitaryware and brassware after finishes. Quoting them separately keeps refit costs transparent.

Can a bath be converted to a walk-in shower?

Commonly, yes: the supply adapts easily and the waste is re-routed for a low-profile tray, with the critical detail being fall to the existing stack and proper tanking before tiling. We handle the wet side and flag any structural implications early.
