You’ve noticed the smell. Or maybe the water is draining slowly, or you heard a gurgling noise from the sink that just doesn’t go away. You’re fairly sure something isn’t right with your drains, but you have no idea what, where, or how serious it is. That feeling of not knowing is frustrating, and it can lead people to either ignore the problem or throw money at solutions that don’t actually fix anything. That’s exactly where a CCTV drain survey changes everything. Instead of guessing, a trained drainage engineer sends a small waterproof camera directly into your pipes and shows you, in real time, exactly what’s happening underground. No digging, no disruption, no guesswork. In this guide, we’ll walk you through what a CCTV drain survey actually involves, when you need one, how the process works, and how to avoid the most common mistakes homeowners make with drain problems. Whether you’ve been searching for a CCTV drain survey near me or you’re just starting to research your options, you’ll find everything you need right here. What Is a CCTV Drain Survey? Put simply, it’s a close-up inspection of the inside of your drainage system using a specialist camera. A CCTV drain survey uses a flexible rod with a high-definition waterproof camera at the tip. This gets fed through an access point, usually a manhole or inspection cover, and travels through your pipework while transmitting live footage back to a screen above ground. The camera captures everything: cracks, root intrusions, blockages, collapsed sections, joint displacements, and even the early signs of problems that haven’t caused noticeable symptoms yet. Everything is recorded, and you typically receive a full report with footage and a written condition assessment at the end. “Before the survey, we had no idea the old clay pipe under the garden had completely collapsed. Without the camera footage, we’d have spent years clearing blockages without ever solving the real problem.” — Homeowner in Perth, Scotland It’s worth knowing that this isn’t the same as a basic drain inspection. A quick visual check at the manhole can only tell you so much. A proper CCTV survey travels through the entire run of pipework and documents condition across the full length. When Should You Get One? There are a handful of situations where a CCTV survey isn’t just useful, it’s the only sensible move. You’re buying or selling a property A standard property survey doesn’t look at drains in detail. If you’re buying a house, especially an older one, getting a CCTV survey done before exchange gives you a clear picture of what you’re taking on. Drain repairs can be expensive, and it’s far better to know about problems before you complete a sale than to discover them six months later. You have recurring blockages If your drains keep blocking despite being cleared, something deeper is causing it. A camera survey will find the root cause, literally, in some cases, as tree roots are one of the most common culprits in older properties across Perth and surrounding areas. Slow draining or bad smells These are early warning signs that something is building up or breaking down inside your pipework. Catching it early almost always means a simpler, cheaper fix. Before or after drainage works If you’re having drainage work carried out, whether it’s a repair, a new extension, or any groundworks near existing pipes, a pre- and post-survey helps document the condition and confirms that everything is done correctly. How the Process Works, Step by Step Initial assessmentThe engineer arrives and locates your access point, usually a drain inspection cover in the garden or driveway. They’ll briefly discuss any symptoms you’ve noticed and make a note of what areas to focus on. Camera insertionA self-levelling waterproof camera is fed into the drain via a flexible push rod or a motorised crawler for longer runs. It transmits live footage directly to a monitor so the engineer can watch in real time. Full pipe inspectionThe camera travels through the length of the drainage run. The engineer stops at any point of interest, cracks, blockages, root ingress, sags in the pipe, and logs the location using built-in distance tracking. Footage and reportEverything is recorded and you receive a written report with the footage, a description of any defects found, and a recommendation for what action, if any, needs to be taken. Honest advice on next stepsA good drainage company will tell you whether you need urgent work, routine maintenance, or simply monitoring. Not every survey results in expensive repairs. What Problems Do CCTV Surveys Typically Uncover? Over years of working in drainage across Perth and Perthshire, the same issues come up time and again. Here’s what the camera most commonly finds: Most Common Findings Root ingress from nearby trees working through joints in older clay pipes Cracked or fractured pipes, especially in properties more than 40 years old Grease and fat build-up creating solid blockages in kitchen waste lines Displaced or misaligned joints from ground movement or settlement Collapsed pipe sections that cause persistent and total drainage failure Foreign objects, sometimes from building work, sometimes just bad habits Corroded or deteriorating pipe materials in older properties   What’s important to understand is that many of these problems don’t cause obvious symptoms in their early stages. A crack might drain fine for months or years before it collapses. Root ingress starts small and gradually gets worse. Catching these things early, before they become emergencies, is one of the biggest advantages of a survey. Tips, Do’s and Don’ts A few things that genuinely help when dealing with drain issues: Do’s Book a survey before buying any property Keep a note of when and where symptoms appear Ask for a written report with footage included Act on early warning signs before they escalate Check if your home insurer covers drainage repairs   Don’ts Don’t pour fat or grease down the kitchen sink Don’t flush wet wipes, even “flushable” ones Don’t ignore slow draining or recurring smells Don’t assume no symptoms means
