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

London water notes: London's supply is hard — Thames Water draws heavily from chalk aquifers and the Thames itself, so limescale builds fast on heating elements, shower heads and tap internals. London's stock runs from Victorian and Georgian terraces with generations of altered pipework to high-rise flats with pumped and boosted supplies, and each brings its own failure patterns. Mains supply here is managed by Thames Water.

Small works: the everyday bathroom list

The routine calls across London: 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

For London bathroom projects we quote the wet-side scope in two clean stages: first fix (rerouting supply and waste to the new layout, testing before close-up) and second fix (fit, connect and commission everything after finishes). Correct waste falls, accessible isolation and a documented pressure test before boarding are non-negotiables — they're the difference between a bathroom and a future claim. London's stock runs from Victorian and Georgian terraces with generations of altered pipework to high-rise flats with pumped and boosted supplies, and each brings its own failure patterns.

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 London engineers test before they quote, so you're paying to fix the leak you actually have.

Bathroom plumbing costs in London

Small works from £120 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 London 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.
