Bathroom Plumbing Services in Wandsworth

Vetted & insured engineers Clear pricing before work starts G3-qualified for unvented cylinders No gas work — plumbing only

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

Wandsworth water notes: Wandsworth's hard water works steadily on cylinders and shower valves — in a borough full of loft-extended family terraces, scaled unvented systems are a recurring theme. Wandsworth is the natural home of the extended Victorian terrace — Balham, Earlsfield and 'between the commons' houses with loft bathrooms and unvented cylinders — plus the vast new riverside stock at Nine Elms and Battersea. Mains supply here is managed by Thames Water.

Small works: the everyday bathroom list

Leaking basin and bath wastes, failed traps, dripping or seized taps and mixers, running and leaking toilets, showers running cold or weak, silicone strip-and-reseal, resealing around trays and baths, replacing wastes and plugs, fixing towel-rail weeps on the wet side, and swapping like-for-like sanitaryware. Most are one-visit jobs in Wandsworth, priced before work starts.

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

Bathroom plumbing costs in Wandsworth

From £99 for defined small jobs in Wandsworth; larger scopes are quoted, never run on an open meter. For refits, you'll get first fix and second fix as separate line items, isolation valves and testing included as standard rather than sold as extras.

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.
