Drainage problems are more than an inconvenience — they are a health hazard and a property risk. Standing water, sewage backups, foul odours and slow-draining fixtures all signal issues in your below-ground or above-ground drainage system that require professional intervention. MAMOSS drainage engineers handle everything from simple blockage clearing to complex drain repairs, relining, and new drainage installations. We use CCTV drain cameras to inspect and diagnose problems accurately, avoiding guesswork and unnecessary excavation. We work on domestic and commercial drainage systems across London, including foul drains, surface water drains, combined systems, soakaways, and interceptor chambers. Whether the issue is a blocked kitchen sink or a collapsed main sewer, we have the equipment and experience to resolve it. - Drain unblocking (mechanical and high-pressure jetting) - CCTV drain surveys and reports - Drain repair and replacement - Drain relining (no-dig repair) - Root removal from drainage systems - Soakaway installation and repair - Manhole and inspection chamber repairs - Fat, oil and grease (FOG) trap installation ## What Happens When Drainage Problems Are Left Unresolved? Drainage faults worsen over time. What starts as a slow drain becomes a structural problem, a health hazard or both: ### Sewage Backup into Property A blocked or collapsed drain can force raw sewage back through your toilets, sinks and floor drains. The contamination risk is severe, and professional decontamination can cost thousands. ### Subsidence and Structural Damage A leaking or collapsed drain saturates the subsoil beneath your property. Over months, this can cause foundation movement, cracking and subsidence — one of the most expensive structural repairs a property can face. ### Rat and Pest Infestation Damaged drains provide an entry point for rats directly into your property. A cracked pipe or displaced joint underground is an open invitation for vermin to access your home through the drainage system. ### Environmental and Legal Liability If contaminated water from your property reaches waterways or neighbouring land, you can face prosecution from the Environment Agency and liability for clean-up costs. Maintaining your drains is a legal responsibility. Our Process ## How We Solve Drainage Problems Systematically 1 ### CCTV Survey & Diagnosis We insert a high-resolution camera into your drainage system to identify blockages, cracks, collapses, root ingress and displaced joints. You see the footage in real-time and receive a detailed report. 2 ### Clear Quotation Based on the CCTV findings, we provide a fixed-price quote for the recommended repair or clearance. We explain all options, including traditional excavation and no-dig alternatives. 3 ### Blockage Clearance or Repair For blockages, we use high-pressure water jetting and mechanical rodding. For structural faults, we carry out excavation repairs, pipe replacement or no-dig relining depending on the situation. 4 ### Post-Work CCTV Verification After the repair, we run the CCTV camera again to confirm the drain is clear, structurally sound and flowing correctly. You receive before-and-after footage and a completion report. 5 ### Prevention Advice & Guarantee We advise on preventing future issues and provide a guarantee on all work. For commercial clients, we offer planned drainage maintenance schedules. ## Why London Properties Trust MAMOSS for Drainage ### CCTV-First Approach We diagnose before we dig. Our CCTV surveys pinpoint the exact problem, preventing unnecessary excavation and reducing costs. ### High-Pressure Jetting Our jetting equipment clears even the most stubborn blockages — fat, grease, scale, roots and debris — restoring full flow without chemicals. ### No-Dig Repair Options Where possible, we use trenchless relining technology to repair damaged drains without excavating your garden, driveway or flooring. ### Same-Day Emergency Response Sewage backup? Flooding? Our drainage team responds within 60 minutes across London for urgent drainage emergencies. ### Insurance-Ready Reports Our CCTV reports and drainage surveys are formatted for insurance claims, property sales and pre-purchase due diligence. ### Full Multi-Trade Support Need plumbing, reinstatement or building work after a drainage repair? We handle everything in-house — no need for separate contractors. ## Comprehensive Drainage Services for London Properties Our drainage services cover the full lifecycle of a drainage system — from installation and maintenance to emergency repair and replacement. For residential properties, the most common issues we resolve are blocked toilets, kitchen sink blockages caused by fat and food waste, root ingress from nearby trees, and displaced joints in aging clay or pitch fibre pipework. CCTV drain surveys are the foundation of our diagnostic process. We use pan-and-tilt cameras that navigate bends and junctions to provide a complete picture of your drainage system. Survey reports include annotated footage, condition grading and repair recommendations. These reports are accepted by mortgage lenders, insurance companies and local authority building control. For drain repairs, we offer both traditional excavation and no-dig (trenchless) solutions. Patch relining is used for localised cracks and joint displacements, while full relining creates a new pipe within the existing one. For severe collapses, we excavate and replace the affected section with modern PVCu or polypropylene pipe to current standards. Commercial drainage services include grease trap installation and maintenance for restaurants and food premises, interceptor servicing for car parks and industrial sites, and planned preventative maintenance schedules for managed buildings. We also carry out pre-purchase drainage surveys for commercial property transactions. Our drainage engineers work closely with our plumbing team to ensure seamless service from the internal stack pipe down to the main sewer connection. Where a drainage issue has caused internal water damage, we can coordinate trace-and-access work, leak repair and reinstatement through a single point of contact. - Pre-purchase and homebuyer drain surveys - Pitch fibre pipe replacement - Clay drain repair and replacement - Grease trap installation and maintenance - Tree root removal and root barrier installation - Septic tank and cesspit servicing - Surface water drainage and SuDS installation - Drainage connection to mains sewerExplore more of our services: Home•Gas & Heating•Plumbing Services•Electrical Services•Emergency Plumber•Areas We Cover•Get a Free Estimate FAQ ## Frequently Asked Questions ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">How much does drain unblocking cost in London? ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">How do I know if my drain is blocked? ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">What is a CCTV drain survey? ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">How long does a drain repair take? ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">Can tree roots damage my drains? ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">Do you offer no-dig drain repairs? ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">Can you help with a drainage insurance claim? ### svg]:rotate-180 text-sm font-semibold text-surface-dark-foreground hover:no-underline py-4" data-radix-collection-item="">What areas do you cover?
