Know the area

Plumbing in Clapham

Clapham is largely Victorian terraces, with an unusually high proportion in multiple occupation or split into flats. Heavy use is the theme running through most jobs here: bathrooms and kitchens serving more people than the original system was ever designed for, showers running back to back through the evening, and waste pipes that block more often as a direct result. A significant part of what we do in Clapham is landlord repairs and getting a flat turned around between tenants.

Our services

What we cover in Clapham

  • Emergency Plumbing

    Burst pipes, major leaks and no water. We take calls around the clock and get an engineer moving.

  • Boiler Repair

    No heat, no hot water, or a boiler locked out on a fault code. Diagnosed first, then fixed.

  • Boiler Service

    The annual check that keeps a boiler safe, efficient and inside its warranty terms.

  • Boiler Installation

    A new boiler sized for the property, fitted properly, with the price agreed first.

  • Boiler Replacement

    Replacing a boiler that has reached the end, with a straight answer on whether it has.

  • Drain Unblocking

    Sinks, toilets and outside drains cleared with proper equipment, not a bottle of chemicals.

  • Leak Detection

    Hidden leaks traced with acoustic and thermal equipment, before floors come up.

  • Bathroom Installation

    A single fixture swap through to a full strip-out and refit, priced up front.

  • Toilet Installation

    A new toilet fitted, an old one swapped, or a WC moved to somewhere it has never been.

  • General Plumbing

    Taps, toilets, radiators and pipework. The jobs that never quite get done.

  • Commercial Plumbing

    Offices, restaurants, retail and blocks of flats, worked around your opening hours.

  • Gas Safety Certificates

    Landlord gas safety certificates issued by a Gas Safe registered engineer, with the paperwork sent the same day.

  • CCTV Drain Surveys

    A camera down the drain shows what is actually wrong, rather than guessing from what keeps happening above ground.

  • Drain Repairs

    A drain that is actually broken, not just blocked — repaired by digging it up or, where the run allows, without digging at all.

  • Wet Rooms & Walk-In Showers

    Level-access showers and full wet rooms, with the tanking and falls that decide whether it leaks in five years or never.

  • Air Conditioning Repair

    A system that has stopped cooling, is leaking indoors, or is tripping the breaker — diagnosed before anything is quoted.

  • Air Conditioning Maintenance

    Annual maintenance that keeps a system cooling efficiently and catches a refrigerant leak before it becomes a breakdown.

  • Air Conditioning Installation

    Split and multi-split air conditioning, sized and sited properly, fitted by F-Gas registered engineers.

  • Air Conditioning Replacement

    Swapping out a system that is worn out or failing — including older units on a refrigerant that can no longer be topped up.

  • Blocked Toilet

    A toilet that will not flush away, or one that keeps blocking. Cleared, with the cause explained.

  • Shower Installation

    Mixer, thermostatic and digital showers fitted — matched to the water system you actually have.

  • Shower Repair

    Weak flow, wandering temperature, no hot water or a leak — diagnosed and repaired, usually without a new shower.

  • Bath Installation

    One bath out, another one in — or the bath out and a shower in its place.

  • Tap Repair and Replacement

    Dripping, stiff and leaking taps repaired, and tired ones swapped for new.

  • Lead Pipe Replacement

    Old lead supply pipes replaced with new, from the boundary into the house.

  • Pipe Repair

    Burst, split, frozen and corroded pipework repaired — or replaced where patching it would be pointless.

  • Low Water Pressure

    Weak taps and showers diagnosed by testing, not by swapping parts and hoping.

  • Central Heating Installation

    The whole system — boiler, pipework, radiators and controls — rather than a new boiler on its own.

  • Surface Water Drainage

    Rainwater with nowhere to go — standing water on patios, paths and gardens, given somewhere to drain.

  • Gutter Repair

    Blocked, leaking, sagging and overflowing gutters cleared and repaired, along with the downpipes below them.

  • Leaking Ceiling

    Water dripping or pouring through a ceiling. What to do first, then the source found and stopped — in your home or the flat above.

  • Toilet Repair

    Toilets that will not flush, keep running, fill slowly or leak onto the floor. Usually one worn part, replaced without needing a new toilet.

  • Leak Repair

    Leaks you can see — dripping joints, weeping valves, perished hoses, overflows running outside — isolated, repaired and checked properly afterwards.

  • Electrical Repairs

    Tripping circuits, dead sockets, faulty lighting and extractor fans, traced and fixed with the price agreed first.

  • Emergency Electrician

    Power loss, trips that will not reset, burning smells and water in the electrics. We take calls around the clock.

  • EICR Certificates

    Electrical Installation Condition Reports for landlords, homeowners and buyers, with any remedial work priced separately.

  • Fuse Box Replacement

    Old fuse boxes swapped for modern consumer units with RCD protection, tested, certified and notified for you.

  • Rewiring

    Full and partial rewires for houses and flats, planned around you and the other trades, then tested and certified.

  • EV Charger Installation

    Home charge points surveyed, fitted, notified and certified, with any supply upgrades priced up front.
