A toilet that will not flush, a sink that repeatedly backs up or an overflowing outside drain can quickly become more than a minor inconvenience. Wastewater appearing around a manhole, unpleasant drain odours or multiple fixtures draining slowly at the same time may indicate a blockage further along the system. If the problem keeps returning, damaged pipework or a recurring obstruction could be responsible.
ASAP Drainage assists homeowners, tenants, landlords and businesses throughout Barnes, including flats, period properties, riverside developments, schools, restaurants, offices and retail premises.
How engineers reach Barnes: SW13 is one of ASAP Drainage’s core South West London coverage areas. Engineers travel via local routes, including Castelnau, Rocks Lane and Lonsdale Road, with arrival times influenced by traffic and access conditions. An estimated attendance window is provided when booking.
ASAP Drainage deals with urgent blockages, recurring faults and underground pipe damage. Its engineers carry professional clearance and inspection equipment, allowing the first visit to be matched to the symptoms described when booking.
Fixed quote on the phone
Blocked drains can affect sinks, showers, toilets and outside drainage. Engineers clear internal and external pipework, identify obstruction locations and restore normal flow as quickly as possible.
Fixed quote on the phone
A blocked toilet can quickly become disruptive. Engineers clear toilet blockages in residential and commercial properties, while checking for wider drainage issues where necessary.
Quoted after survey
Damaged drains may suffer from cracks, root ingress, displaced joints or collapsed sections. CCTV inspection helps identify defects before suitable repair options are recommended.
Quoted after survey
Drain lining repairs certain damaged pipes internally using a resin liner. This method can reduce excavation requirements while restoring structural integrity and improving flow.
From £149 +VAT
CCTV surveys provide detailed footage of underground drainage conditions. Reports include defect identification, drainage layouts, photographs, and recommendations for any necessary remedial work.
Describe the symptoms when you call. The booking team can advise whether the first visit should focus on clearance, CCTV inspection, drain tracing or an assessment of suspected structural damage.

There is no single published rate for every blocked drain because the work varies according to access, depth and the material causing the obstruction. Before booking, the team asks where the problem is, which fixtures are affected, and whether an accessible manhole or rodding point is available. A fixed quotation is then confirmed before the engineer travels.
What moves the price: The cost may depend on whether the blockage is indoors or outside, its distance from the nearest access point and whether a basement or lower-ground area is involved. Communal drainage and repeated blockages can also call for a camera inspection before the underlying fault becomes clear.
CCTV surveys are priced separately from straightforward clearance. When damaged pipework is identified, the engineer explains the evidence and supplies a written quotation before repair or lining work begins.

The scope is agreed before work continues. Large houses, schools, apartment buildings, and commercial properties may have several drainage runs or restricted access points. These sites can require a wider survey and are priced according to the work involved.
ASAP Drainage covers homes, schools and businesses across SW13. Property types, drainage layouts and access arrangements vary significantly throughout Barnes.
Period homes, conversions and local businesses often have older drainage systems. CCTV surveys and targeted clearance help identify recurring drainage issues.
Houses, flats and school premises feature varied drainage networks. Services include emergency unblocking, CCTV inspections and pre-extension drainage assessments.
Homes near mature landscaping may have ageing underground pipework. Camera surveys and drain tracing help establish condition and identify defects.
Riverside properties, apartments and hospitality venues can experience communal drainage issues. Investigations, repairs and emergency clearance are regularly requested.
Larger homes, schools and sports facilities may contain multiple drainage runs. Mapping, surveys and blockage investigations support effective maintenance.

ASAP Drainage takes emergency calls 24 hours a day, seven days a week, including overnight, weekends, and bank holidays.
A toilet may overflow in a Barnes Village house, or a blocked pub drain may interrupt service near the riverside. Sewage entering a basement flat or a communal obstruction affecting several apartments also needs prompt assessment. Emergency work is handled by ASAP Drainage and attended by one of its directly employed engineers. Call for the current attendance estimate and confirmed quotation.
Owners generally look after internal waste pipes, gullies within the property boundary and private drains serving only their address. This includes the private section running from the building until it reaches a shared sewer or public lateral drain.
Responsibility can be harder to establish in converted houses, flats, mansion blocks, managed developments, mixed-use buildings and properties reached by shared private roads. Communal pipework within a site may be the responsibility of a freeholder, landlord, managing agent or management company.
Thames Water generally maintains public sewers, public lateral drains, and qualifying shared sewer sections. Once a pipe begins carrying waste from neighbouring properties, responsibility may transfer to Thames Water, even where the shared section crosses private land.
An ASAP Drainage engineer can investigate where the obstruction appears to sit, whether one or several properties are affected and whether the drain is private or shared.
Our approach: when inspection evidence identifies a fault within Thames Water’s network, you will be advised to report it rather than approve private remedial work that may not be your responsibility.
Tenants and leaseholders: notify your landlord, freeholder or managing agent where shared or communal drainage may be involved. Liability depends on the affected pipe, the building arrangement and the cause of the blockage.
Explain which fixture or drain is affected, whether wastewater is overflowing and whether several outlets have stopped working. The property type, floor level, access arrangements, parking restrictions, and managing-agent details help the team identify the likely service, quotation, and expected arrival window.
A directly employed engineer attends with equipment for common drainage clearance and inspection work. The estimated arrival time is based on current traffic, workload, access conditions, and the location of the available engineer.
The engineer chooses equipment according to the blockage and pipe condition. Drain rods, high-pressure water jetting, mechanical cutters, flex-shaft cleaning, CCTV cameras or sonde tracing equipment may be used.
If pipe damage is found, the customer receives supporting evidence and a separate remedial quotation. Qualifying completed work carries the applicable 28-day workmanship guarantee, subject to the company’s terms and recommendations.

Had a big blockage issue that previous plumber couldn’t fix. Chase and Billy do an excellent job, fixed the issue and cleaned up at the end. Really grateful to them both.

Really efficient, friendly and timely service provided. Had a few bad experiences in the past with other services, this was a breath of fresh air! Highly recommend.
— Stuart A, Google review
Excellent job uninstalling one radiator and fitting a new one with underfloor pipes. Work was undertaken quickly by a knowledgeable worker. No fuss and a good price.

The quotation depends on access, the obstruction’s location and the equipment required. ASAP Drainage asks about the symptoms before confirming a fixed price ahead of attendance. CCTV surveys and repairs are priced separately, so additional work should not proceed without explanation and customer approval.
Barnes is a priority South-West London location. You receive an estimated arrival time when booking, based on traffic, workload, the engineer’s current position and local access conditions. Railway crossings and congestion on surrounding routes may affect the journey, so a precise time is not guaranteed.
Yes. Emergency drainage assistance is available 24 hours a day, including overnight, weekends and bank holidays. Call with your SW13 postcode, property type and a description of the blockage so the booking team can confirm the current attendance estimate and fixed quotation.
Coverage includes Barnes Village, Castelnau, Barnes Common, Barnes Bridge, Lonsdale Road, Queen’s Ride, and surrounding SW13 streets. Properties near Mortlake, Roehampton or Putney may carry SW14 or SW15 postcodes and should be checked individually before an appointment is arranged.
Thames Water generally maintains public sewers, public lateral drains and adopted shared sections. A private drain serving only one property usually remains the owner’s responsibility. In flats or managed developments, the freeholder or managing agent may be responsible for communal pipework inside the site.
Yes. A homebuyer CCTV survey can document the accessible pipe condition, drainage layout and visible defects. It is useful for period houses, extended properties, flats and homes with mature gardens. Reports can include recorded footage, a schematic, defect coding and repair recommendations.
Roots can enter a pipe through an existing crack, open joint or damaged section and then restrict the flow. However, the presence of nearby trees does not prove root damage. CCTV inspection is needed to identify whether roots are present and assess the pipe around the entry point.
Recurring obstructions may involve grease, wipes, scale, roots, displaced joints, poor gradients, damaged pipework or a fault within communal drainage. Repeated clearance may restore flow without identifying the cause. A CCTV survey can reveal defects that are not visible during routine unblocking.
Emergency drainage support for rental properties, schools, and managed developments, including communal investigations, CCTV reporting, key-holder attendance, and planned maintenance for recurring drainage issues.
Pre-purchase CCTV surveys provide evidence of drainage conditions, recorded footage, and reports to help identify defects, drainage alterations, and potential concerns before property transactions.
