What we get called to here

The faults Clapham
keeps producing.

Every area has its own pattern, set by when the houses were built and what has been done to them since. This is ours for Clapham.

Water through the ceilingThe most common Clapham callout. We trace the source from the flat above and repair it with minimal opening up, then check the affected area properly.
Blocked shared wasteOne stack, several kitchens. We clear from the right access point and test the run under load rather than declaring it clear after a plunge.
Boilers in cupboardsCombis squeezed into hallway cupboards with tight clearances. We work with what is there and flag anything that breaches the manufacturer's spacing.
What we do in Clapham

One team,
every trade.

Plumbing, gas and electrics under one roof, so a bathroom or a boiler swap here does not need three separate contractors booked around each other.

Leaks, burst pipes and blocked waste across SW4 and SW9, attended the same day. We handle access with neighbours and agents where the job needs it.

Repairs and servicing for the combis that dominate Clapham's flats, plus replacement where a unit is past economic repair.

Refits where the soil stack, the floor and the lease all shape what can be moved. We check consent requirements before design, not after.

A large share of SW4 is rented. CP12s, EICRs and reactive repairs booked directly with tenants and reported back the same day.

Local knowledge

Why Clapham plumbing
behaves the way it does.

Knowing the housing stock means arriving prepared rather than discovering the complication halfway through the job.

Clapham is dominated by Victorian terraces split into flats, often decades ago and rarely with the plumbing redesigned to match. One soil stack serves several kitchens and bathrooms, waste runs pass through other people's ceilings, and the stopcock for your flat is frequently in a communal cupboard somebody has painted shut.

It changes how a job runs. Isolating water can mean speaking to a neighbour, access sometimes needs the managing agent, and a leak reported by the flat below has to be traced from above without opening more ceiling than necessary. We work in these buildings constantly, so none of that is a surprise on the day.

★★★★★

Had a burst pipe on a Sunday evening and TopFix sent someone out within the hour. The plumber explained exactly what was wrong, fixed it cleanly and left everything tidy.

Booked a full bathroom refit. The team was punctual and the price matched the quote exactly. Our older Victorian house had complicated pipework and they handled it without any fuss.

SKSarah K.

★★★★★

Used TopFix twice now, once for a boiler service and once for a radiator that was not heating. Both times on time, honest about the cost and the job done properly.

Clapham questions

Asked before
most local jobs.

Not sure whether we reach your street? Ring and ask — we will tell you straight away rather than take a booking we cannot keep.

Call 020 3095 1113
Do you work in converted flats?

Constantly — it is most of what we do in Clapham. Shared stacks, communal stopcocks and access through neighbours are all part of the normal job here.

Water is coming through my ceiling. What now?

Turn off your own water if you can and call us. The source is nearly always in the flat above, and we will trace it without taking down more ceiling than we have to.

Do you cover Abbeville and Clapham Park?

Yes, along with Old Town, the Common, Clapham North and the Stockwell side of SW9.

Pricing, Gas Safe and booking

All gas work by Gas Safe registered engineers, price agreed up front, fully insured. Call (020) 3095 1113 and we will find a slot.
