Properties across St Just and the Land's End peninsula sit on some of Cornwall's most challenging ground. Granite bedrock limits natural drainage, exposed Atlantic weather drives high seasonal rainfall, and much of the housing stock consists of former miners' cottages and stone-built farmhouses served by ageing clay or pitch fibre pipework. Outside the town itself, most rural properties rely on private septic tanks and soakaways that are rarely documented in title deeds. A CCTV drain survey records the actual condition and layout of the system beneath your property, giving you evidence you can act on. Clear Stream Drainage Solutions surveys properties across St Just and the surrounding TR19 postcode. Our engineers attend with no call-out fee and a fixed price agreed before any work begins.
St Just's drainage network reflects centuries of development, from its medieval origins to its growth as a major tin-mining town. Historic cottages, chapels, and commercial buildings often rely on ageing pipework laid across ground affected by former mining activity, where old shafts and disturbed land can increase the risk of drainage issues. The town's exposed coastal location also accelerates wear from salt-laden air. In nearby areas such as Pendeen, Botallack, Sennen, and St Buryan, many properties rely on private septic tanks affected by local clay soils and granite bedrock. As much of this infrastructure is poorly documented, a CCTV drainage survey is often the only reliable way to understand what lies beneath a property.
A drainage survey is something you book in advance, not something you call out in a crisis. The situations below are where St Just 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 Holiday Let 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 the private system ends and the public sewer network begins. In St Just, where private runs frequently cross beneath the lanes connecting Bank Square and Market Square, shared yards behind the granite terraces, and miners' rows feeding off Chapel Road and Fore Street, this part of the survey is often the most valuable. For rural properties across West Penwith, the mapping function is even more important, since deeds rarely capture the actual layout of septic systems, soakaways, and shared private runs between cliff-edge farms and cottages.
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 facing a major repair bill within months. In St Just this matters most for the town's listed buildings around the two squares, granite miners' cottages now widely converted into holiday lets, properties built on or close to former mine workings where pipe gradients have been affected by historic ground movement, post-war housing with pitch fibre runs prone to deformation, and rural homes on septic systems across West Penwith where soakaway condition is invisible without inspection.
Build-over surveys are required wherever new construction sits within 3 metres of a public sewer. In St Just this requirement comes up regularly, because the historic core around the two squares is served by sewer runs following the original miners' town layout, and most extension or conversion work in the centre sits close to one. The continued programme of holiday let upgrades and barn conversions across the surrounding parishes 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 DoA survey gives you a clear starting point. Once we have mapped the drainage layout and recorded any defects, we can carry out repairs, set up scheduled maintenance, or produce the documentation needed for a property sale, insurance claim, or building project. Across the St Just area we work with homeowners, buyers, landlords, holiday cottage owners, lettings agencies, B&B operators, chapel and community building managers, smallholdings, and farms toward Pendeen, Botallack, Sennen, and the surrounding parishes.
Our team clears blockages quickly and safely, restoring full flow and preventing further damage to your system.

A clear answer on ownership is one of the most practical outcomes of a St Just 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. St Just complicates this in ways the town's mining heritage and remote rural layout make inevitable. Private drains routinely cross beneath the lanes connecting Bank Square and Market Square, shared yards behind the granite terraces, miners' rows, and farm tracks before reaching a public sewer, and the boundary point is rarely clear from deeds alone. 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 very high proportion of rural properties on private septic systems across West Penwith, including most homes toward Pendeen, Sennen, Botallack, and the cliff-edge 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 those near former mining ground. A significant proportion of St Just buyers commission one voluntarily, especially on listed buildings, granite miners' cottages, and 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 St Just 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 St Just and the wider West Penwith peninsula, including pre-purchase surveys for buyers of rural homes. The vast majority of properties on the peninsula run on private systems, and 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.
