Falmouth's position as a working port, university town, and popular visitor destination means its drainage infrastructure serves a wide range of property types under varying levels of demand. The historic streets around the harbour and Conservation Area contain some of the oldest pipework in the town, now shared between permanent residents, student lets, holiday accommodation, and commercial premises. Higher up, the residential streets toward Penwerris and Swanpool include Victorian and Edwardian housing with original clay drainage, while the university campus and surrounding student housing place concentrated seasonal load on systems that were designed for lower occupancy. A CCTV drain survey records what condition the pipework is actually in, maps the layout, and identifies who is responsible for each section. Clear Stream Drainage Solutions surveys across Falmouth and the surrounding TR11 postcode with no call-out fee and a fixed price confirmed before we begin.
EXCELLENT Based on 59 reviews Posted on Google IanTrustindex verifies that the original source of the review is Google. Excellent fast service. Very polite and professional.Posted on Google Rachel JonesTrustindex verifies that the original source of the review is Google. I recently used Clear Stream for a problem with a septic tank and could not recommend them more highly. From the initial call out onwards they were knowledgeable, professional, helpful and conscientious. They originally attended as an emergency call out. Despite it being the May bank holiday they arrived within an hour and charged a really reasonable price for an emergency service. When it became clear that the problem was significant and we would need a new tank they installed a temporary fix then provided a detailed quotation for the major works, including answering insurers’ questions. The new tank was installed over a two day period in which they work really efficiently, while keeping me updated and informed about every stage. The guarantees for their work are reassuring and they made a stressful situation so much easier. I would highly recommend them to anyone.Posted on Google Gina MartinTrustindex verifies that the original source of the review is Google. Josh - what a superstar. The only reason I haven’t given 5 stars is … I will have to pay the bill. Josh really put me at ease. I have been stressing about the blocked drain for two weeks. He got on with the job.

Josh was quick to reply to my online query, and arranged to come out the same day. He quickly assessed the likely issue with the standing water and blocked drain, and promptly cleared it. His communication was great, I was advised of the cost up front, and everything was dealt with in a friendly and professional manner.

Falmouth's drainage tells a story you cannot read from the surface. The Georgian and Victorian terraces along Arwenack Street, Killigrew Street, and the lanes behind the harbour rely on original clay pipework now serving properties subdivided into flats, holiday lets, and student accommodation many times over their original design load. The salt-laden maritime air that defines Falmouth life accelerates corrosion at joints, manhole frames, and any iron-and-clay transitions, in a way inland properties simply do not experience. The town's steep gradients down from Pendennis Rise, Old Hill, and Wodehouse Terrace funnel surface water hard during winter storms, putting cyclical pressure on combined sewers that already run close to capacity. The university presence pushes thousands of additional residents into HMOs and student lets across Trescobeas, Woodlane, and the streets feeding the Penryn Campus, where pipework laid for single-family use carries the kitchen and bathroom load of six- and eight-tenant properties. Out toward Mawnan Smith, Maenporth, and the lanes toward Constantine, many properties depend on private septic tanks where soakaway saturation in clay subsoils and the granite bedrock below make excavation slow. A CCTV drain survey is the only way to see what is actually happening inside any of these systems before it becomes a flooded ground floor or a five-figure repair bill.
A drainage survey is a planned investigation, not an emergency response. The triggers below are the most common reasons Falmouth homeowners, buyers, and landlords commission one. If any apply to your property, the case for a survey is strong.
Before You Buy A Property
Repeated Blockages At The Same Point
Build Over Or Building Control Compliance
Insurance Claims And Disputes
Persistent Damp Or Foul Smells
Pre-Letting Or Property Portfolio Documentation
A good survey is more than pointing a camera down a manhole. The value sits in the diagnosis, the report, and the recommendations. Our engineers follow a structured process designed to give you documented evidence that holds up in front of a solicitor, a mortgage lender, an insurer, or a Building Control officer.
We feed a high-resolution waterproof camera through the drainage system from existing access points, with no digging or disruption to the property. The footage is reviewed live on-site so we can identify defects as we encounter them. For larger-bore pipework on commercial sites, we use crawler-mounted cameras suited to the diameter.
We map the run of pipework across the property, mark the location of every access point, and confirm where the private system ends and the public sewer begins. This matters in Falmouth, where shared private drains often cross neighbouring properties before joining a public sewer, and ownership is rarely clear from deeds alone.
Cracks, displaced joints, root ingress, partial collapses, scale build-up, misconnections, and pitch fibre deformation are all identified, located, and recorded. We grade defects by severity so you can see what needs attention now and what can be monitored.
You receive a written report including HD video footage, still images of every defect, a drainage layout plan, condition grading, and recommendations for any remedial work needed. Reports are formatted to be shared directly with solicitors, mortgage lenders, insurers, and Building Control where required.
The drainage system is one of the few parts of a property a standard building survey will not investigate, and one of the most expensive things to fix retrospectively. A pre-purchase CCTV drain survey in Falmouth typically pays for itself many times over the moment a defect is identified before exchange. Buyers use the report to renegotiate the purchase price, request that repairs are completed by the vendor before completion, or walk away from a purchase that would have left them facing a five-figure repair bill within months. For Falmouth's stock of pre-1900 terraces with original clay drainage, post-war properties with pitch fibre runs prone to deformation, and rural homes on private septic systems, a survey is the only way to know what you are actually buying.
If you are planning an extension, conservatory, garage conversion, or any structure within 3 metres of a public sewer, South West Water and Building Control will typically require a build-over survey before approving the work. The survey confirms the location, depth, and condition of the affected pipework, identifies any existing defects that need addressing before construction, and provides the documented evidence needed to obtain a build-over agreement. Our engineers handle the survey end-to-end and produce reports formatted to South West Water and Building Control standards.
With the drainage system mapped and any defects documented, we can carry out repairs, set up a maintenance programme, or provide the evidence needed for a property sale, insurance claim, or building project. Across the Falmouth area we work with homeowners, buyers, listed building owners, student accommodation providers, landlords managing HMOs and conversion flats, lettings agencies, hotels, guest houses, restaurants, pubs, harbour-side businesses, boat yards, retail premises, developers, and university-linked property managers.

One of the most useful outputs of a CCTV drain survey in Falmouth is a clear answer to a question that catches a lot of homeowners out: which parts of the drainage system are yours, and which belong to South West Water? The general rule is simple. Anything inside your boundary, including the lateral run from the property to the boundary line, is yours to maintain and repair. Once a pipe leaves your boundary and joins a shared sewer serving multiple properties, it falls under South West Water. The complication in Falmouth comes from the town's tightly packed historic layout, where shared private drains often cross neighbouring courtyards, alleys, and the back lanes between Killigrew Street and the harbour before reaching a public sewer, and ownership is rarely clear from the deeds alone. Our survey establishes exactly where the boundary sits, which sections you are responsible for, and which can be escalated to South West Water with the documented evidence the survey provides. For rural properties on private septic systems toward Mawnan Smith, Constantine, and the lanes toward the Helford, the entire system is yours, and the survey gives you a complete map of what you own.
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 are completed within one to two hours on-site. The written report and video footage are typically delivered within a few working days, formatted for sharing with solicitors, lenders, or insurers as required.
Most high-street lenders do not automatically require one, but many will request a survey if the standard building survey flags potential drainage concerns, particularly on older properties or those with a history of issues. Many Falmouth buyers commission a survey voluntarily as part of due diligence, regardless of lender requirements.
If significant defects are identified, the written report and video footage give buyers the documented evidence needed to renegotiate the purchase price, request that repairs are completed by the vendor before completion, or withdraw from the purchase. We provide the evidence; the negotiation is between you and your solicitor.
If any part of the proposed structure sits within 3 metres of a public sewer, you will typically need a build-over survey for South West Water and Building Control approval. We carry out build-over surveys regularly and produce reports to the required standards.
Yes. We carry out full septic tank surveys, soakaway investigations, and CCTV inspections of private drainage runs across the rural areas around Falmouth, including pre-purchase surveys for buyers of rural properties.

If we identify a fault that 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.
