Our directly employed engineers clear blocked drains, toilets, outside gullies, and manholes using high-pressure jetting and professional equipment.

You receive a fixed quotation before travel, with coverage across the town centre, East Common, West Common, Dukes Wood, Bulstrode Park, and nearby roads.

A drainage fault can begin quietly with one slow sink, then spread to toilets, showers or outside gullies. Rising water, sewage around a manhole, persistent smells or a blockage returning soon after clearance all deserve prompt investigation.
ASAP Drainage attends detached homes, gated residences, period properties, private roads, flats, rentals, restaurants, offices, schools and larger commercial sites.
How attendance is arranged: Gerrards Cross is a Buckinghamshire priority location. Engineers may travel via the M40, M25, A40, A413 and local roads. Traffic, school periods and restricted access can affect arrival times. The booking team confirms the estimated window before dispatch, and every engineer is directly employed.
Whether the problem is a sudden obstruction or an unexplained recurring fault, ASAP Drainage provides clearance, camera diagnosis, tracing and underground pipe repair.

The cost becomes clearer once the team understands what is blocked and how the drainage can be reached. Before booking, the customer describes the affected fixtures, available access and property type. ASAP Drainage then confirms the agreed quotation before the engineer travels.
What moves the price: The scope may depend on whether the blockage is internal or external, the nearest manhole, and the obstruction’s distance from that point. Roots, grease, scale, compacted debris, jetting, mechanical cutting, recurring fault history, and private road access can also affect the work.
CCTV surveys are priced separately from drain clearance. Larger homes and long private drainage runs may need a wider inspection. Repairs and lining receive a separate written quotation after diagnosis. Additional work only proceeds after approval, and structural recommendations should be supported by recorded evidence.

A failed toilet or overflowing drain can make a home, restaurant or office unusable within a short period. ASAP Drainage operates 24 hours a day, including overnight, weekends and bank holidays.
Emergency jobs may involve an overflowing toilet in an SL9 home, a restaurant drain backing up near Packhorse Road, sewage around a garden manhole or a blocked external drain on a private drive. Flats and offices may also need urgent help. Directly employed engineers attend emergency work, with response times based on postcode, traffic, access and engineer location.
Owners generally maintain internal waste pipes, gullies inside the boundary and private drains serving only their property. This may include drainage serving garages, annexes, outbuildings, private soakaways, and pipework before it becomes shared.
Responsibility can be more complicated on private roads, gated developments, shared drives, flats and mixed-use sites. A landlord, freeholder, estate manager, residents’ company or facilities team may need to approve work involving communal private drainage.
Thames Water generally maintains public sewers, public lateral drains and adopted shared sections, including qualifying pipes serving more than one property and public sewer assets beneath roads or pavements.
An ASAP Drainage engineer can investigate whether the obstruction appears private, shared, communal or public. The findings can indicate whether Thames Water or a property manager should be contacted.
Our approach: Private repair work should not be approved when the available evidence identifies a Thames Water asset.
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.
Provide the postcode, symptoms, property type and access details. Mention multiple affected fixtures, sewage overflow, gates or private roads. The team confirms the likely service, quotation and estimated attendance window.
A directly employed engineer attends with equipment for common blockage clearance, CCTV surveys and drain tracing. Arrival depends on traffic, access and the nearest available engineer.
The engineer clears the obstruction where possible. High-pressure jetting, rods, mechanical equipment, CCTV cameras or tracing tools may be used.
If damage is identified, the customer receives camera evidence and a separate repair quotation. Qualifying remedial work carries the applicable 28-day workmanship guarantee.
When the problem sits underground, reliable evidence matters more than assumptions. ASAP Drainage is family-run, has operated since 2012, and brings more than 15 years of drainage experience to emergency and scheduled appointments.
Engineers are directly employed, while CCTV reports and repair quotations are prepared internally. MSCC5 defect coding helps explain recorded pipe faults before customers decide whether remedial work should proceed.

The national names (Dyno-Rod, Metro Rod, Drain Doctor) route Guildford jobs through franchisees. We’ve been one family’s company since 2012, same standards, same engineers, every job.
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.

Drain unblocking costs vary depending on the location of the blockage, ease of access, and the equipment needed to clear it safely. ASAP Drainage provides a fixed quotation before an engineer travels to the property, so there are no unexpected charges. CCTV surveys, drain tracing and repair work are quoted separately where required, and any additional services only proceed once the customer has approved them.
Gerrards Cross is one of ASAP Drainage’s priority service locations. When you call, the booking team will provide an estimated attendance window based on your postcode, current traffic conditions, access arrangements, engineer availability and workload. Travel times can be affected by congestion on routes such as the M40 or M25, as well as gated developments, private roads or restricted access requirements.
Yes. ASAP Drainage operates 24 hours a day, including overnight, weekends and bank holidays, for urgent drainage problems. If you have a blocked drain, overflowing toilet or sewage backup, call with your postcode and property details. The team will confirm availability, provide a fixed quotation before attendance and advise on the current estimated arrival time for an engineer.
Coverage includes Gerrards Cross town centre, the station area, East Common, West Common, Dukes Wood, Bulstrode Park and surrounding SL9 addresses. Properties close to Chalfont St Peter, Denham, Fulmer, Stoke Poges and Iver Heath may also be covered, subject to postcode confirmation. Providing the full postcode allows the booking team to confirm availability and the expected attendance arrangements.
In many cases, Thames Water is responsible for public sewers, public lateral drains and adopted shared drainage infrastructure. Private drains serving only one property are usually maintained by the property owner. For flats, apartment blocks or managed developments, responsibility may rest with a landlord, freeholder or managing agent. An engineer can help identify the likely ownership of the affected drainage section.
Yes. A homebuyer CCTV drain survey can provide recorded footage, a written condition report, a drain schematic, MSCC5 defect coding and recommendations for any accessible drainage defects. These surveys can be particularly useful when purchasing larger homes, properties with extensions, houses on private roads or buildings where the drainage layout is unclear before completion.
Yes. Tree roots can enter drainage systems through cracks, displaced joints or damaged pipework and gradually restrict wastewater flow. However, the presence of mature trees or large gardens does not automatically mean roots are causing the problem. CCTV inspection should be used to confirm root ingress before root cutting, drain lining or structural repairs are recommended as a solution.
Yes. Drain tracing and mapping services can identify accessible pipe routes, approximate depths, manholes and drainage connections before extension projects, driveway installations or landscaping work begins. The information can help homeowners, builders and designers understand the existing drainage layout and determine whether a more detailed Build Over survey or further investigation may be required.
Recurring drain blockages can result from grease accumulation, wipes, scale deposits, root ingress, displaced joints, damaged pipework, poor gradients or faults within shared drainage systems. While routine clearance may temporarily restore flow, the underlying issue can remain unresolved. A CCTV drain survey can identify the cause and help determine whether further cleaning, maintenance or repair work is necessary.
