A CCTV drain survey uses a high-definition waterproof camera mounted on a flexible push-rod or crawler unit to inspect the inside of underground drainage pipework. The video feed is recorded and reviewed alongside a written report classifying any defects according to industry-standard WRc Manual of Sewer Condition Classification codes. Drainage problems are almost impossible to diagnose accurately without seeing inside the pipework. A blockage that keeps coming back, a smell with no obvious cause, water backing up into the wrong gully, sinkholes appearing in a garden, or persistent damp in a basement — all of these are typically caused by underground defects that only a CCTV survey can identify with certainty. MAMOSS provides CCTV drain surveys across Bethnal Green and East London for homebuyers, homeowners, landlords, insurers and managing agents. From £150 for a standard survey, we deliver same-day digital video and a written report with photographs and exact location measurements of every defect. - Pre-purchase / homebuyer drain survey - Insurance claim documentation (subsidence, escape of water) - Recurring blockage root cause diagnosis - Pre-renovation survey before basement / extension build - Build Over Agreement compliance for Thames Water - Post-repair verification of relining or excavation - Tree root ingress identification - Build-over compliance and Thames Water mapping ## When You Should Order a CCTV Drain Survey Some drainage symptoms point so reliably to underground defects that a CCTV survey is essential before any other work is carried out: ### Blockages That Keep Returning If a blockage clears with rodding or jetting and then returns within weeks or months, an underground defect — usually root ingress, a fractured pipe or a partial collapse — is causing material to snag and accumulate. ### Multiple Drains Affected Slow drainage in multiple sinks, baths or toilets simultaneously points to a problem in the shared underground pipework rather than individual fixture traps. CCTV identifies the location precisely. ### Buying a Property Drainage repairs are expensive (£3,000-£15,000+ for excavation and relining) and not visible in a homebuyer survey. A CCTV survey before exchange identifies risks and is often a basis for price negotiation. ### Sinkholes or Subsidence Localised sinking ground above a drain run almost always indicates a collapsed pipe leaking and washing away supporting subsoil. CCTV plus location electronics confirms the location for excavation or no-dig repair. ### Insurance Subsidence Claim Subsidence claims caused by escape of water from drains require CCTV evidence to be accepted. Insurers will only consider claims with WRc-coded survey reports — exactly what we provide. ### Basement or Extension Planning Before any major building work over or near drains, you need to know exactly where the drain runs and what condition it is in. Build Over Agreements with Thames Water require this evidence. Our Process ## Our CCTV Survey Process 1 ### Initial Discussion We discuss what you want from the survey — homebuyer assessment, insurance claim, blockage diagnosis, etc. — and confirm scope (foul drains, surface water drains, internal soil pipes, or all of the above). 2 ### Access Point Identification We locate access chambers (manholes), inspection covers, rodding eyes and gully traps. Where access points are missing or insufficient, we may use a roof vent or remove a toilet pan to access internal pipework. 3 ### Pre-Clean If Required Heavily blocked drains are cleared with high-pressure jetting before survey — you cannot inspect what you cannot see. The clearance is included in the survey fee on most jobs. 4 ### Camera Inspection A push-rod or crawler camera is inserted and recorded as it travels through the system. Distance from access is logged for every defect, allowing precise location for any future repair. 5 ### Defect Coding & Mapping Every observation is coded to WRc Manual of Sewer Condition Classification standards (cracks, fractures, displaced joints, root ingress, etc.) with severity ratings. A pipe location plan is created showing the route and depth of every drain run. 6 ### Digital Report & Video You receive a PDF report with photos, defect codes, location measurements and recommendations, plus the full HD video file by digital download. Reports are formatted to satisfy insurers, mortgage lenders and Thames Water Build Over Agreements. ## Why Choose MAMOSS for CCTV Drain Surveys ### Same-Day Surveys Most surveys booked by 11am can be carried out the same day. Urgent jobs (property exchange, insurance deadline) prioritised on request. ### WRc-Coded Reports All defects coded to industry-standard WRc Manual of Sewer Condition Classification — the format required by insurers, water companies and mortgage lenders. ### HD Video Included Full high-definition video footage of the survey supplied as a digital file. Useful for sharing with your solicitor, surveyor, insurer or for second opinions. ### Repair Quotes Included Where defects are found, we provide a fixed-price repair quote — patch lining, relining, excavation, etc. No obligation to use us, but you have the cost benchmark immediately. ### Insurance & Mortgage Ready Reports are formatted to satisfy every UK home insurer's subsidence claim requirements and every major mortgage lender's drainage condition criteria. ### Pipe Location Mapping We use a sonde and locator to map the exact route and depth of every drain run — essential for Build Over Agreements with Thames Water and for any future excavation work. ## CCTV Drain Surveys in Detail: Reports, Repairs & No-Dig Options A CCTV survey is the diagnostic stage — but the value comes from what you can do with the information. Most defects we find can be repaired without excavation using modern no-dig techniques, which are dramatically cheaper and less disruptive than traditional dig-up-and-replace. Patch lining is used for localised defects: a resin-impregnated fibreglass patch is positioned at the exact defect location using the CCTV survey measurements, inflated against the pipe wall with an air bladder, and cured in place to form a seamless internal repair. Costs from £450 per patch and lasts 50+ years. Full pipe relining (cured-in-place pipe, or CIPP) is used where defects extend along longer sections. A resin-soaked fabric liner is inverted into the existing pipe, inflated to the pipe wall, and cured to form a new pipe inside the old one. Suitable for most domestic drainage and far cheaper than excavation. Where defects are too severe for relining (full collapse, displaced joints requiring re-alignment, or pipework requiring re-grading) we excavate and replace. The CCTV survey tells us exactly where to dig — a 2 m trench instead of a 10 m exploration trench — minimising disruption and cost. For insurance claims (escape of water causing subsidence), we follow the ABI Code of Practice for Subsidence Claims. Our reports are formatted to insurer specification with defect codes, photographs, video evidence and a clear opinion on whether the damage is consistent with the observed defects. We have provided successful evidence for hundreds of London subsidence claims. - Standard residential CCTV survey — from £150 - Pre-purchase / homebuyer survey with full report — £180 - Insurance subsidence survey (ABI compliant) — £225 - Commercial / multi-occupancy survey — quote on enquiry - Patch lining repair from £450 (no excavation) - Full pipe relining from £85 per metre - Drain location and mapping for Build Over Agreement — £150 - Same-day reporting in PDF + HD video Explore more of our services: [Home](/)• [Gas & Heating](/services/central-heating-engineer)• [Plumbing Services](/services/plumber)• [Electrical Services](/services/electrician)• [Emergency Plumber](/services/emergency-plumber)• [Areas We Cover](/areas)• [Get a Free Estimate](/contact) FAQ ## Frequently Asked Questions ### How much does a CCTV drain survey cost? ### How long does a CCTV survey take? ### Do I need a CCTV survey before buying a house? ### Will my insurance pay for the survey? ### What if you find a problem? ### Do you supply video footage? ### Is the report accepted by Thames Water for Build Over Agreements? ### Do you cover Hackney, Shoreditch and Stratford?
