Callington is a small market town surrounded by agricultural land on the eastern edge of Cornwall, close to the Devon border. The town centre contains a mix of older stone-built properties and more recent residential development, while the surrounding Tamar Valley parishes are predominantly rural, with farms, barn conversions, and isolated dwellings relying on private septic tanks and soakaways. Ground conditions across this area vary between heavy clay and the slate bedrock of the Tamar catchment, both of which affect how drainage systems perform over time. A CCTV drain survey records the condition and layout of the system beneath your property and produces a report you can use for purchases, repairs, planning applications, or portfolio management. Clear Stream Drainage Solutions surveys across Callington and the surrounding PL17 postcode with no call-out fee and a fixed price agreed before we begin.
Callington sits on the south-western slopes of Kit Hill in some of the most heavily mined ground in Cornwall, and the legacy of that history runs directly beneath the modern town. In the 18th and 19th centuries this was one of the most important mining areas in Britain, with copper, tin, and silver extracted from a network of shafts and adits that left the surrounding land riddled with disturbed strata, abandoned workings, and engine house ruins still visible today around Wheal St Vincent and Kit Hill. Pipework laid through ground that has shifted over more than two centuries of mining behaves very differently from pipework in undisturbed clay or sand, and faults related to gradient change, joint failure, and partial collapse appear with unusual frequency. The historic core along Fore Street and Tavistock Road retains a dense run of listed Georgian and Victorian properties built when household drainage was rudimentary and now subdivided into flats, professional offices, and apartments above shops, all served by clay pipework laid in pieces over the last 150 years. The granite that defines the local landscape, still quarried on Hingston Down, also makes excavation slow and expensive when faults require dig-up repair. Out toward Kelly Bray, Frogwell, Newbridge, and the lanes toward the Tamar and Lynher rivers, most properties depend on private septic tanks, with soakaway performance constrained by the heavy clay subsoils and shillet bedrock common across the Tamar Valley. None of this is reliably documented in property paperwork. A CCTV survey is the only way to know what is genuinely in the ground.
A drainage survey is something you book in advance, not something you call out in a crisis. The situations below are where Callington 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 Callington, where private runs frequently cross beneath neighbouring back gardens, shared yards, and the access lanes off Fore Street and Tavistock Road, this part of the survey is often the most valuable.
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 Callington this matters most for the town's listed Georgian and Victorian stock along Fore Street, properties built on or close to former mining ground 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 where soakaway condition is invisible without inspection.
Build-over surveys are required wherever new construction sits within 3 metres of a public sewer. Callington's residential extension activity, conversion of older buildings into residential use, and continuing infill development across the town all generate regular demand for these surveys. 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 provides the documented foundation for whatever comes next. Once defects are identified and the drainage layout recorded, we carry out repairs, schedule maintenance, or supply the evidence required by a solicitor, lender, insurer, or Building Control officer. Across the Callington area we work with homeowners, buyers, landlords, lettings agencies, agricultural businesses, equestrian properties, barn conversion owners, developers, and rural property owners toward Gunnislake, Stoke Climsland, Kelly Bray, 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 Callington 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. Callington complicates this in ways the town's mining heritage and market town layout make inevitable. Private drains routinely cross beneath neighbouring back gardens, the courtyards behind Fore Street, and the access strips connecting older properties to shared yards before reaching a public sewer, and the boundary point is rarely clear from deeds alone. Older properties converted into flats or commercial use 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 Stoke Climsland, Linkinhorne, and the farms across the Tamar Valley, 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 Callington buyers commission one voluntarily, especially on listed Fore Street stock 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 Callington and produce reports to the required standards.
