Helston's drainage infrastructure serves a medieval market town that has grown outward from a dense historic core toward the Lizard Peninsula and the surrounding rural parishes. The original pipework beneath Coinagehall Street, Meneage Street, and the central Conservation Area now handles waste from residential conversions, commercial premises, and a hospitality sector that peaks during Flora Day and the summer season. Properties across the surrounding area toward Porthleven, Breage, Wendron, and Cury frequently rely on private septic systems affected by high water tables and heavy clay subsoils. A CCTV drain survey identifies the condition and layout of the system beneath your property before a concealed defect becomes a costly repair. Clear Stream Drainage Solutions surveys across Helston and the surrounding TR13 postcode. No call-out fee, and a fixed price agreed in writing before any work begins.
Helston’s drainage network reflects over 800 years of history. Once a medieval coinage town and former port, its development was shaped by the tin trade and the silting of the Cober River, which created Loe Pool and still influences local drainage patterns today. In the town centre, many listed buildings along Coinagehall Street, Meneage Street, Church Street, and Wendron Street rely on ageing Victorian pipework, often complicated by property conversions and heavy use from restaurants and pubs. In surrounding rural areas such as Porthleven, Sithney, Wendron, and the Lizard Peninsula, most properties depend on private septic tanks, with drainage often affected by heavy clay soils and serpentine bedrock. As much of this infrastructure is undocumented, a CCTV drainage survey is often the only reliable way to assess what lies beneath the ground.
A drainage survey is something you book in advance, not something you call out in a crisis. The situations below are where Helston property owners get the most value from one. If any apply to you, a survey is worth booking.
Before You Buy A Property
Recurring Faults At The Same Location
Extensions And Build Over Approval
Insurance, Legal, And Subsidence Evidence
Unexplained Damp, Smells, Or Garden Patches
Landlord And Portfolio Documentation
A survey is only as useful as the report it produces. Our engineers work to a structured process that delivers evidence usable by lenders, solicitors, insurers, and Building Control officers, not just a memory stick of raw footage.
A waterproof HD camera is fed through the drainage system from existing access points, with no excavation. Footage is reviewed live so defects can be discussed on-site as they are found. Crawler cameras are used where larger-bore commercial pipework requires them.
We trace the full layout of the pipework, identify every access point, and confirm where private responsibility ends and the public sewer network begins. In Helston, where private runs frequently cross beneath the back yards behind Coinagehall Street and Meneage Street, shared lanes serving the listed terraces, and the strips of ground sloping toward the Cober valley, this part of the survey is often the most valuable. For rural properties across the Lizard, the mapping function is even more important, since deeds rarely capture the actual layout of septic systems, soakaways, and shared private runs between farms.
Every cracked joint, displaced section, root mass, scale deposit, misconnection, and pitch fibre deformation is logged, located, and graded. You see immediately which defects require attention and which can be left for ongoing monitoring.
The deliverable is a full report containing HD video, still images of each defect, a drainage plan, defect grading, and recommendations. Format is suitable for direct submission to solicitors, mortgage lenders, insurers, and Building Control.
The single most expensive blind spot in a property purchase is the drainage system. A standard building survey does not investigate it. A pre-purchase CCTV survey closes the gap before you exchange, and the cost is small relative to what it can reveal. Buyers use the report to negotiate the purchase price down to reflect defect repair costs, require the vendor to complete remedial work before completion, or pull out of a sale that would have left them with a major bill. In Helston this matters most for the town's listed Georgian and early Victorian stock along Coinagehall Street and the conservation area, period buildings where any repair carries planning sensitivity, holiday lets and converted barns sold as going concerns where drainage condition is rarely declared, and the large number of rural homes on septic systems across the Lizard Peninsula where soakaway condition is invisible without inspection.
Build-over surveys are required wherever new construction sits within 3 metres of a public sewer. In Helston this requirement comes up often, because the dense conservation area and the historic streets descending from the Guildhall to the Grylls Monument are served by sewer runs following the original street layout, and most extension or conversion work in the centre sits close to one. The continued programme of barn conversions and rural extensions across the Lizard adds further regular demand. Our build-over surveys document the location, depth, and structural condition of the affected sewer, identify any defects that must be addressed before construction begins, and provide the evidence Building Control and South West Water require before issuing approval. Reports are produced to the format and standard those bodies expect.
What We DoThe survey report provides the documented evidence you need for the next step, whether that is a targeted repair, a maintenance schedule, a property transaction, or a planning application. Across the Helston area we work with homeowners, buyers, listed building owners, landlords, lettings agencies, holiday park operators, caravan site owners, pubs, restaurants, retail premises, developers, and rural property owners toward Porthleven, the Lizard Peninsula, and the surrounding parishes.

A clear answer on ownership is one of the most practical outcomes of a Helston CCTV survey, and one of the most common reasons homeowners book one. The principle is straightforward. Pipework inside your boundary, including the lateral connection running out to the boundary line, is yours to maintain and repair. Once that pipe joins a shared sewer carrying waste from multiple properties, responsibility transfers to South West Water. Helston complicates this in ways the town's stannary-era street layout makes inevitable. Private drains routinely cross beneath the back yards behind Coinagehall Street, shared lanes serving the listed terraces along Meneage Street and Wendron Street, and the strips of ground threading toward the Cober valley before reaching a public sewer, and the boundary point is rarely clear from deeds alone. Listed buildings converted into multiple flats add a further layer of shared private pipework that historic documents do not capture. Our survey establishes the actual layout, identifies the boundary point, confirms which sections belong to you, and provides the evidence needed to escalate any public-sewer fault to South West Water. For the high proportion of rural properties on septic systems toward the Lizard, including most homes from Mullion and Cadgwith out to St Keverne and the moorland farms, the entire network is yours, and the survey produces a complete map of what that means in practice.
We agree a fixed price before any work starts, with no call-out fee and no diagnostic charge. Standard residential surveys typically fall within the range buyers and homeowners would expect to pay locally, with the exact figure depending on property size, number of access points, and the level of reporting required. You have the cost in writing before we book the appointment.
Most residential surveys take one to two hours on-site. The written report and footage are usually delivered within a few working days, formatted for sharing with solicitors, lenders, or insurers as needed.
Most high-street lenders do not require one as standard, but many request a survey when the main building survey flags drainage concerns, particularly on older properties or rural homes on septic systems. A significant proportion of Helston buyers commission one voluntarily, especially on listed Coinagehall Street stock and Lizard Peninsula rural properties.
If significant defects are identified, the report and footage give you documented evidence to renegotiate the purchase price, require the vendor to complete repairs, or withdraw from the purchase. We provide the evidence; the negotiation sits between you and your solicitor.
If the proposed structure sits within 3 metres of a public sewer, a build-over survey is normally required for South West Water and Building Control approval. We handle build-over surveys regularly across Helston and produce reports to the required standards.
Yes. We carry out full septic tank surveys, soakaway investigations, and CCTV inspections of private drainage across the rural areas around Helston and the Lizard Peninsula, including pre-purchase surveys for buyers of rural homes. The very high proportion of properties on private systems across the Lizard means we work on them every week.
All repairs we carry out following a survey are covered by our 5-year guarantee. If a repaired section fails inside that period, we return and put it right at no cost.
If a fault needs immediate attention, we discuss the options with you on-site. In most cases we can quote and address the issue on the same visit, with the cost agreed in writing before any work begins.
