St Ives places exceptional demand on its drainage infrastructure. The steep, narrow streets of the old town were laid out for a fishing community, and the pipework beneath them now serves a dense mix of permanent homes, holiday lets, guest houses, galleries, restaurants, and retail premises with occupancy levels that peak sharply during the summer season. Many properties in the Downalong area and along the harbour share drainage runs that are difficult to access and poorly documented. A CCTV drain survey establishes what condition that pipework is actually in and who is responsible for each section. Clear Stream Drainage Solutions carries out surveys across St Ives and the surrounding TR26 postcode for homeowners, buyers, holiday let owners, landlords, and commercial operators. No call-out fee, no diagnostic charge, and a fixed price agreed before we begin.
St Ives has over 1,500 years of history, and much of its drainage infrastructure reflects centuries of piecemeal development. Historic fishermen's cottages, former artists' studios, galleries, restaurants, and holiday lets all rely on ageing drainage systems that were never designed for today's visitor numbers. Harbour-side businesses place additional pressure on the network, while salt-laden coastal conditions can accelerate wear and deterioration. In nearby areas such as Carbis Bay, Lelant, and Zennor, many properties depend 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 Ives 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 Hospitality 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, which matters in St Ives given the concentration of converted gallery, restaurant, and cellar-conversion premises around the harbour.
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 Ives, where private runs frequently cross beneath the labyrinthine cobbled alleys of Downalong, shared courtyards behind Fore Street and Back Road East, and the strips of ground threading between the harbour and the upper streets, this part of the survey is often the most valuable. For rural properties across Penwith, the mapping function is even more important, since deeds rarely capture the actual layout of septic systems, soakaways, and shared private runs between 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 Ives this matters most for the town's listed harbour-side stock, white-washed fishermen's cottages across the Downalong quarter, converted net lofts and former cellar buildings now operating as galleries, studios, or holiday lets where the original drainage was never designed for residential or commercial conversion loads, restaurant and food business premises sold as going concerns, and rural homes on septic systems across 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 Ives this requirement comes up often, because the dense Downalong conservation area and the streets above the harbour are served by sewer runs following the original medieval and Victorian layout, and most extension, conversion, or fit-out work in the centre sits close to one. The continued programme of holiday let upgrades and barn conversions across Penwith 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 DoWith the survey complete and the drainage layout documented, we can proceed directly to any remedial work, schedule ongoing maintenance, or provide the evidence a solicitor, insurer, or lender requires. Across the St Ives area we work with permanent residents, second-home owners, holiday let operators, Airbnb hosts, guest house and hotel owners, galleries, restaurants, cafes, surf shops, retail premises, lettings agencies, developers, and buyers navigating the town's competitive property market.

A clear answer on ownership is one of the most practical outcomes of a St Ives CCTV survey, and one of the most common reasons homeowners and business owners 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 Ives complicates this in ways the town's medieval Downalong layout makes inevitable. Private drains routinely cross beneath the labyrinthine cobbled alleys radiating from the harbour, shared courtyards behind Fore Street and Back Road East, and the strips of ground threading between adjacent fishermen's cottages converted into multiple lets before reaching a public sewer, and the boundary point is rarely clear from deeds alone. Converted net lofts, cellars, and former workshops now operating as studios, galleries, or holiday accommodation 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 rural properties on septic systems toward Zennor, Towednack, and the inland 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 with previous conversion or commercial use. A significant proportion of St Ives buyers commission one voluntarily, especially on listed harbour-side stock, Downalong cottages, converted studios, 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 Ives 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 Ives and the wider Penwith peninsula, including pre-purchase surveys for buyers of rural homes. The high proportion of properties on private systems across Penwith 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.
