A CCTV drain survey in Blackpool typically costs between £100 and £250. Most drainage companies charge for it as a separate service — often recommended at the end of a clearance job as an upsell. We don’t. Every drain clearance we carry out across Blackpool and the Fylde Coast includes a free CCTV validation survey as standard — not as an add-on, not as a sales technique, but because we believe a cleared drain and a structurally sound drain are two different things, and you deserve to know which one you’ve got.
Here’s exactly what the validation survey includes, why it matters, and how to get yours.
Validating Our Specialisation: Why We Include a Validation Survey with Every Unblocking
When a drain contractor clears a blockage and tells you the drain is flowing again, they’re telling you the truth. Water is passing through the pipe. What they’re often not telling you — because they haven’t checked — is whether the pipe is fully clear, whether there’s a structural defect at the blockage site, or whether the same blockage will reform in three weeks from the same underlying cause.
The difference between a drain that’s flowing and a drain that’s genuinely clear and structurally sound is the difference between a temporary fix and a permanent one. That difference is a camera.
Why we include it when others charge extra
The honest answer is that it costs us time — typically fifteen minutes per job. But we include it as standard for three reasons that we think matter more than those fifteen minutes.
First, it holds us accountable. When our camera goes through the pipe after jetting, you see the footage with us. If the blockage hasn’t been fully cleared, the camera shows it immediately and we continue jetting until it has. There’s no room for a half-cleared job to be presented as a complete one.
Second, it protects you. A CCTV validation that identifies a root ingress entry point or a displaced joint gives you information you need to prevent the same blockage recurring — and options to fix the underlying cause rather than just the symptom. Without that information, you’re paying for clearances that will keep coming back.
Third, it reinforces why we describe ourselves as specialists rather than simply drain clearance contractors. Anyone with a jetting machine can push water through a pipe. A specialist confirms the work is genuinely complete.
Post-clearance CCTV — the camera confirms the pipe is genuinely clear and identifies any structural defects at the blockage location.
What the validation survey specifically confirms
- Full clearance — the pipe bore is clear from the jetting point to the connection with the main drain, with no remaining debris, root mass or grease coating
- Pipe wall condition — the internal surface of the pipe is assessed for grease sleeve residue that may have been only partially cleared by jetting
- Structural integrity at the blockage site — the area of the pipe where the blockage occurred is inspected for cracks, joint failures, root entry points and other structural defects
- Flow gradient — the camera confirms the pipe has an adequate fall for drainage — flat or back-falling sections trap debris and cause recurring blockages regardless of how thoroughly the pipe is cleared
CCTV Structural Integrity Check vs. Generic Unblocking
CCTV structural validation after clearance — the difference between knowing water is flowing and knowing the pipe is genuinely sound.
Understanding the difference between generic unblocking and CCTV structural validation is central to understanding why recurring blockages happen — and how to stop them.
| What you get | Generic Unblocking Only | Unblocking + CCTV Validation |
|---|---|---|
| Water flows after the job | Yes | Yes |
| Confirmation pipe is fully clear | No | Yes — camera confirmed |
| Grease sleeve assessed | No | Yes |
| Root ingress identified | No | Yes — entry point located |
| Cracked or displaced joints found | No | Yes |
| Partial collapse identified | No | Yes |
| Repeat blockage risk assessed | No | Yes |
| Evidence for deposit disputes (landlords) | No | Yes — photographic record |
| Insurance claim evidence | No | Yes |
| Cost | Clearance fee only | Same — CCTV included free |
For landlords in particular, the CCTV validation record after every clearance is not just useful — it’s operationally essential. A photographic and summary record of what caused each blockage is the primary evidence accepted by tenancy deposit scheme adjudicators in disputes about whether a blockage was caused by tenant misuse or structural failure. Without it, you’re relying on assertion rather than evidence. Our landlord drainage guide covers this in detail.
Identifying Hidden Issues (Root Ingress, Displaced Joints) Before They Fail
The most valuable aspect of a CCTV validation survey is not confirming what you already suspected — it’s finding what you didn’t know was there. In Blackpool’s older FY postcode properties with Victorian clay drainage, the camera regularly surfaces hidden defects that are the real reason a drain keeps blocking, and that would never be identified by jetting alone.
The hidden defects CCTV finds that jetting misses
Jetting can clear a root mass and restore flow. But unless the camera identifies the exact crack or joint failure where the roots entered, you have no way to know whether the roots will regrow from the same point — which they will, typically within weeks to months. The camera locates the entry point precisely, enabling targeted repair with root removal and lining rather than repeated clearing.
When clay pipe sections move out of alignment — through ground settlement, vehicle loading or frost heave — they create open gaps at the joints. These gaps admit root growth, ground water and, in coastal properties, sand. They also allow wastewater to escape into surrounding soil. Displaced joints are completely invisible from outside the pipe and undetectable by jetting — the camera is the only way to identify them and assess their severity.
A partial collapse — where the pipe has partially caved in but water is still passing — shows up clearly on CCTV but is completely missed by jetting. Partial collapses worsen progressively. Catching them at the partial stage means a repair option of no-dig drain lining — which is significantly cheaper than excavation after a full collapse. Identifying a partial collapse before it fails completely is one of the highest-value things a post-clearance CCTV survey can do.
High-pressure jetting clears the bulk of a grease blockage but does not always strip the grease sleeve — the thin layer of solidified fat coating the internal pipe wall — completely. A pipe that looks clear on flow may still have a significant grease coating that will trap passing debris and reform a blockage within days. The camera identifies residual grease sleeve directly, triggering a second jetting pass until the pipe walls are genuinely clean.
In FY1, FY2 and FY4 properties close to the seafront, sand that has entered through damaged gully pots or cracked lateral pipes settles in low-gradient pipe sections and compacts under passing water. Standard jetting addresses organic blockages but may compact or redistribute sand rather than clearing it. CCTV identifies exactly where sand has accumulated and how much remains after jetting — allowing a targeted second pass with the correct technique to fully clear it.
Every clearance includes a free CCTV validation — you see the camera footage yourself and receive a clear summary of findings before we leave.
How the free validation fits into a wider drain health picture
The post-clearance CCTV validation is not the same as a full pre-purchase survey or a comprehensive drain asset mapping survey — it’s specifically focused on the section of pipe where the blockage occurred and the immediate drain run connected to it. For a complete picture of your property’s entire drainage system, a full CCTV drain survey covering all drain runs is the appropriate service.
However, for the majority of homeowners in Blackpool’s FY postcodes who have a blocked drain cleared, the free validation survey provides exactly the information that matters most — is the drain properly clear, and is there a structural reason it blocked that needs addressing? That’s the question that determines whether you’ll be making the same call again in three weeks or whether the problem is genuinely resolved.
For properties in Blackpool being bought or sold, the free validation survey is not a substitute for a full homebuyer drain survey — which surveys all drain runs and produces a written report formatted for solicitors and mortgage lenders. But if you notice a drain problem during viewing, a clearance with free CCTV validation gives you a rapid indication of the drain condition that can inform whether a full pre-purchase survey is warranted.
