What we see most often in SW London homes

The housing stock across SW, KT, SM and TW postcodes is a mix of Victorian terraces, 1930s semis, mansion blocks and newer flats — each with its own recurring faults. These are the ones we attend most often:

• Old Victorian terraces in SW/KT areas often still have ageing lead or mixed-era pipework, which can cause poor flow, pinhole leaks and awkward tie-ins during a refit.
• Mansion blocks and converted flats commonly have low water pressure, especially on upper floors, so showers may need pressure-boosting or careful valve selection.
• 1960s ex-local-authority flats often have shared soil stacks and boxed-in service runs, making leaks, drain blockages and bathroom reconfigurations more disruptive.
• Hard water from the Thames Water area leads to limescale on taps, shower heads, valves and heating-side components, shortening service life.
• Flat-roofed extensions and older tiled bathrooms in terraced houses can suffer hidden waterproofing failure, causing damp to ceilings and joists below.
• Access constraints in narrow SW London streets, basement flats and mansion blocks often make waste removal, skip permits and material delivery more expensive and slower.

Brands and parts we work with

We carry common-fault parts on the van for the brands found in most SW London properties, so most jobs are resolved on the first visit.

DIY or call a pro?

Honest guidance — sometimes a YouTube tutorial is enough, sometimes calling us is the cheaper option once you factor in damage and time.

• DIY is usually fine for cosmetic jobs such as silicone resealing, changing a shower head, or replacing a toilet seat.
• Call a qualified plumber for any hidden leak, pipe reroute, waste alteration, or replacement of a bath, basin or toilet.
• Use a Gas Safe engineer if the bathroom work affects a boiler, gas pipe, flue, or a heated towel rail tied into the heating system.
• Do not DIY electrical work in bathroom zones unless you are competent and the job is notifiable; use a qualified electrician for fans, lighting, sockets or underfloor heating.
• Structural changes, tanking/waterproofing failures, and shower-drain or stack problems are pro jobs because mistakes can cause major water damage.

How the job runs, from call to invoice

1. 11. Initial call or survey: the installer checks bathroom size, access, existing plumbing, drainage, ventilation and whether a full rip-out is needed.
2. 22. Diagnosis and measurements: they inspect pipe positions, water pressure, damp, tile condition and any hidden issues behind the suite.
3. 33. Written quote: you receive a fixed or itemised quote covering labour, materials, waste removal, skip/permit needs and any extras.
4. 44. Strip-out and preparation: old suite, tiles and fittings are removed; surfaces are repaired and first-fix plumbing/electrics are adjusted.
5. 55. Installation: bath, shower, basin, toilet, waste lines, valves, screens, tiles and sealant are fitted in sequence.
6. 66. Testing and snagging: everything is pressure-tested, leaks are checked, drainage is verified and minor defects are corrected.
7. 77. Tidy-up and invoice: the team cleans the room, removes waste, hands over guarantees/manuals and issues the final invoice.
