Most CCTV drain surveys take between 30 and 90 minutes. The exact time depends on how big your property is, how far the drainage runs, and whether any blockages need clearing first. Simple domestic surveys are usually done within the hour, while larger or more complex systems can take a little longer.
You’ve booked a drain survey, and now you’re wondering how much of your day it’ll swallow up. Will the engineer be gone before lunch? Do you need to take time off work? Will your driveway be dug up in the process?
Good news: a drain survey is one of the least disruptive jobs an engineer can carry out. No digging, no mess, no chaos. Just a small camera, a clear picture of what’s going on underground, and answers you can actually use.
Below, you’ll get a straight answer on how long a drain survey takes, a step-by-step look at what happens on the day, and a few tips to help everything run smoothly.
What Is a CCTV Drain Survey?
A CCTV drain survey is an inspection that uses a small, waterproof camera to look inside your drains and pipes. The engineer feeds the camera through your drainage system and watches a live feed on a monitor.
It’s a bit like a health check for your pipes. Instead of guessing where a problem lies, the camera shows exactly what’s happening cracks, blockages, root intrusion, collapsed sections, or general wear.
People book a CCTV drain survey for all sorts of reasons:
- Buying a home and wanting to check the drains before committing
- Recurring blockages that keep coming back
- Bad smells or slow-draining sinks and toilets
- Damp patches or subsidence near drainage runs
- Getting to the root of a problem before repairs begin
How Long Does a Drain Survey Take?
Most CCTV drain surveys take 30 to 90 minutes. For a standard home in Perth or Dundee with an accessible drainage system, you’re usually looking at the shorter end of that range.
Here’s a rough guide based on property type:
- Small flat or terraced house: 30–45 minutes
- Average family home: 45–60 minutes
- Large property or commercial site: 60–90 minutes or more
If the engineer needs to clear a blockage before the camera can pass through, that adds a bit of time. The same goes for large commercial systems with long runs of pipework and multiple access points.
The upside? A drain survey is quick compared to most drainage work. You won’t be waiting around all day.
What Happens During a Drain Survey?
Wondering how the drain survey process time actually breaks down? Here’s what a typical visit looks like from start to finish.
Step 1: Arrival and quick assessment (5–10 minutes)
The engineer arrives, has a quick chat about the issue you’ve noticed, and locates the best access point usually a manhole cover or inspection chamber. At Drain Master Scotland, engineers are usually on-site within an hour of your call.
Step 2: Preparing the access point (5 minutes)
The cover is lifted and the entry point is checked. If there’s standing water or debris in the way, the engineer clears it so the camera has a clean path.
Step 3: Running the camera (15–45 minutes)
This is the main event. The waterproof camera is fed slowly through your pipes while the engineer watches the live feed. They’ll flag any issues as they go and take note of where each problem sits along the run.
Step 4: Clearing blockages if needed (varies)
If the camera hits a blockage it can’t pass, the engineer may carry out drain unblocking or high-pressure jetting on the spot, then continue the survey. This step is optional and only happens when required.
Step 5: Reviewing the findings (5–10 minutes)
Once the camera is out, the engineer talks you through what they found. You’ll get a clear explanation of any problems and honest advice on what to do next no jargon, no pressure.
Factors That Affect Survey Duration
No two properties are identical, so drain survey duration can vary. A few things make the biggest difference:
- Property size: Bigger buildings mean longer pipe runs and more to inspect.
- Access: Easy-to-reach manholes speed things up. Hidden or buried access points slow things down.
- Blockages: If a blockage blocks the camera’s path, clearing it adds time.
- Drain layout: Older or unusual pipework can take longer to navigate.
- Purpose of the survey: A quick check for a house sale is faster than a full diagnostic on a recurring fault.
Commercial sites almost always take longer than homes, simply because there’s more ground to cover.
What You Receive Afterwards
A drain survey isn’t just about the visit it’s about the answers you walk away with. After a survey with Drain Master Scotland, you can expect:
- A clear explanation of what the camera found
- A recorded video of the inspection, useful for house purchases or insurance
- A written report detailing any faults and their location
- Honest recommendations on repairs or maintenance, with no hard sell
- Transparent pricing for any follow-up work, with no hidden charges
This paperwork is especially handy if you’re buying a property or need proof for a warranty or insurance claim.
Helpful Insights: Do’s and Don’ts
A little preparation goes a long way. Keep these in mind before your survey.
Do:
- Clear access to manholes and inspection covers where you can
- Note down exactly when and where problems happen (slow drains, smells, gurgling)
- Ask the engineer questions they’re happy to explain
- Keep the recorded footage safe if it’s for a house purchase
Don’t:
- Pour chemicals down the drain right before the survey, as it can distort findings
- Block off access points with cars, bins, or storage
- Assume the worst many issues are minor and easily fixed
- Ignore recurring problems, since small faults often grow into bigger ones
A common mistake is booking a survey too late, after a blockage has already caused damage. Catching a problem early with a survey almost always saves money down the line.
