What a CCTV Drain Survey Actually Involves (and What It Doesn't)
A customer called us on a Friday afternoon after noticing a slow-draining bathroom and a faint smell coming from an outside gully. She had already had the drain jetted twice by another company in the space of six months. Each time, the blockage cleared. Each time, it came back. When we put a camera down the line, we found a partially collapsed pipe joint that had been silently catching debris with every flush. Jetting it had never been the solution. It was never going to be.
That is exactly what a CCTV drain survey is for. We feed a small, waterproof camera through your drainage system and watch in real time as it travels through the pipework. We can see the inside of your drains: the condition of the pipe walls, any cracks or fractures, root ingress, misaligned joints, bellying sections where waste sits and accumulates, and the location and nature of any blockage.
What a CCTV survey is not is a guarantee that your drains will stay clear. It is a diagnostic tool. It tells you what is there, where it is, and what caused it. That information is the foundation of a proper repair decision. Without it, you are guessing. And guessing on drains, particularly older clay or concrete pipes common across much of Dublin's housing stock, tends to be expensive.
The Five Situations Where a CCTV Survey Is the Right Call
Not every blocked drain needs a camera. A first-time blockage in a sink or toilet, with no history of problems, is usually a straightforward jetting job. But there are situations where skipping the camera means you will almost certainly be back to square one within weeks or months.
First: recurring blockages. If your drain has blocked more than once in the past year, something structural is causing it. A camera will find it. Second: slow drainage across multiple outlets at the same time. When two or more fixtures drain slowly, the problem is almost always further down the shared line, not at the individual fixture. Third: unexplained odours. A persistent bad smell from a drain or from outside the property is often a fractured pipe or a break in a seal. Our smoke testing service can support this diagnosis, but CCTV usually goes in first.
Fourth: before any major groundworks or extension work. If you are planning a new build, an extension, or landscaping that involves digging near drainage runs, you need to know where the pipes are and what condition they are in before a machine goes near them. Fifth: before purchasing a property. We cover this in more detail below, but a pre-purchase CCTV drain survey is one of the most cost-effective checks a Dublin buyer can make. A structural survey will not go near the drains. Yours should.
Why the Camera Is Only Half the Story
Here is something most companies leave out of their CCTV survey content: the footage on its own is worth very little if the person handing it over cannot tell you what to do with it.
We have spoken to customers who received a USB stick with camera footage from another company, along with a written report that listed findings without explaining what they meant or ranking them by urgency. They did not know whether they needed an emergency repair, a scheduled dig-up, or nothing at all for the next five years. That is not a diagnosis. That is paperwork.
When our engineers carry out a CCTV survey, they walk you through the findings on site. In plain English. They explain what the camera found, what caused it, what will happen if it is left alone, and what the repair options are. Because Dylex has a full drain repair and maintenance capability, including no-dig repairs and civils and groundworks for situations that require excavation, we can follow a survey directly with a repair quotation based on what the camera actually showed, not an estimate made without seeing the pipe.
That matters when you are deciding how to spend money on your property. A survey from a company that only surveys, and then refers you elsewhere for repairs, adds a step and a delay. We remove both.
Pre-Purchase Drain Surveys: The Check Dublin Buyers Are Starting to Take Seriously
When you buy a house in Dublin, you will typically commission a structural survey. Your solicitor will run searches. You might arrange a separate damp report. What most buyers do not do, and what most structural surveyors are not equipped to do, is inspect the drains.
This is a gap that is starting to close. We are carrying out more pre-purchase CCTV surveys than ever, particularly on older terraced properties in Dublin City, semi-detached houses in South Dublin, and period properties in coastal Wicklow towns like Bray and Greystones where clay drainage runs have been in the ground for sixty or seventy years.
Under Irish law, the property owner is responsible for the private-side pipework running from the property all the way to where it meets the public sewer main. Uisce Éireann maintains the public sewer network, but the private run, including any section running under a garden, footpath or road, is the householder's responsibility. If you buy a property with a cracked lateral running under the front path, that repair bill is yours from the moment you sign.
A CCTV survey before contracts exchange takes that risk off the table, or at minimum gives you the information to negotiate. Starting from €250 + VAT, it is a fraction of the cost of a post-purchase drain repair. We produce a full written report with footage, so if you find a problem, your solicitor has something to work with.
Why Dylex Offers CCTV Surveys 24/7, 365 Days a Year — Not Just Monday to Friday
Most drainage companies treat CCTV surveys as a bookable weekday service. We do not. Dylex operates around the clock every day of the year, including weekends and bank holidays, so you are never left waiting when a drainage emergency strikes, or when a time-sensitive situation demands answers before the working week resumes.
The reason this matters in practice: property transactions do not pause for weekends. A survey that reveals a problem on a Friday afternoon needs to be booked and completed before Monday if contracts are due to exchange. A drainage issue that surfaces at 6pm on a Saturday, backing up into a ground-floor bathroom, needs a camera, not a voicemail telling you to call back Tuesday.
We also run our CCTV surveys as part of our emergency drain unblocking response. Every Dylex van carries a drain camera. When we respond to a blockage and clear it, we can run a survey on the same visit if the engineer suspects a structural cause. That is not a standard offering from most drainage companies. It is part of how we work.
What to Expect When You Book a CCTV Survey with Dylex
Booking a CCTV drain survey with us is straightforward. Call our emergency line on 086 014 3937, the helpdesk on 083 371 4504, or the freephone number 1800 929 197, and we will confirm availability and give you an upfront price before anyone sets foot on your property. We do not quote vague ranges and revise them on arrival.
On the day, our engineer will access your drainage system, typically through an external manhole, and introduce the camera into the pipe run. The survey generally takes between one and three hours, depending on the length and complexity of the drain network. You will see the footage as it is recorded. The engineer will talk you through findings in real time and will follow up with a written report and footage you can keep.
If the survey reveals something that needs attention, we will tell you what the options are: whether that is a targeted high pressure jetting treatment, a patch repair using no-dig trenchless technology, or a full excavation and pipe replacement for serious structural failures. You get a clear recommendation, not a menu of possibilities with no guidance on which one to choose.
Dylex holds ISO 9001 certification for quality management and ISO 14001 for environmental management. Those are internationally recognised standards. They mean every survey, every report, and every repair recommendation is produced to a documented quality process, not left to individual interpretation on the day.
How Much Does a CCTV Drain Survey Cost in Dublin?
Our CCTV drain surveys start from €250 + VAT. Out-of-hours surveys are available at a higher rate, though requests outside standard hours are rare for this service. For most residential properties, a standard survey falls in the lower end of that range. Larger sites, commercial properties, or properties with complex drain networks will be priced after we understand the scope.
For context, a structural drain repair following an undiagnosed recurring problem can run from €750 for a targeted no-dig fix up to several thousand euros for a dig-up and pipe replacement. The survey cost is almost always recovered in the certainty it provides. You are not paying for footage. You are paying to know exactly what is in your ground before spending on a repair.
