When you buy a house, you probably check the roof, the windows and the electrics. Yet a hidden network of pipes runs beneath every property, and people often overlook it until something goes wrong. A CCTV drain survey can reveal problems that standard home surveys miss.
What is a CCTV Drain Survey?
A CCTV drain survey sends a small, waterproof camera through your drainage system. The camera records high-definition footage of the pipes as it travels. Engineers can then spot blockages, damage and other problems because they see inside the pipes, with no digging.
Why Standard Home Surveys Don’t Cover Drains
A homebuyer’s survey or full building survey looks at the visible and accessible parts of a property. Drains sit underground, so they fall outside its scope. Unless there is visible evidence like damp or subsidence, drainage problems will not be flagged.
Common Problems Discovered During Drain Surveys
Tree Root Ingress
Tree roots naturally seek out moisture, and your drains provide plenty. Roots can push into pipe joints and cracks. As a result, they can cause complete blockages or even a collapsed pipe. Properties with mature trees nearby face the highest risk.
Collapsed or Broken Pipes
Older properties often have clay or pitch fibre pipes that wear out over time. A CCTV survey can show cracks, breaks and collapses. These problems may need excavation and repair, although a survey shows them early.
Displaced Joints
Ground movement, traffic vibration or poor installation can pull pipe joints apart. Waste can then leak into the soil around the pipe. As a result, the ground may sink over time.
Incorrect Connections
For example, some properties have surface water drains linked to foul sewers, or the other way round. These wrong connections can cause compliance issues.
Fat and Debris Buildup
Even without structural damage, heavy build-up in the pipes can signal future problems. You may want to deal with it before you move in. Our guide to 7 warning signs of a blocked drain shows what to look for.
Why Survey Before You Buy
Drain repairs can be disruptive, especially when excavation is needed. The work involved depends heavily on what is wrong:
- A simple drain unblocking job is usually the least involved fix
- Drain relining is a bigger job, scaling with pipe length and diameter
- Excavation and pipe replacement involve more again, driven by depth, ground conditions and how much surface reinstatement is needed
- A full drainage system replacement is the biggest outcome, and the one a survey is most likely to help you avoid
A pre-purchase CCTV survey shows you the condition of the pipes before you commit. It can help you avoid inheriting someone else’s problem, because you learn about it first. Request a quote online to tell us about the property.
Using Survey Results in Negotiations
A survey is useful because it gives you facts to work with. If it finds issues, you have several options:
- Ask the seller to adjust the terms to reflect the repairs
- Request the seller fix the issues before completion
- Walk away if the problems are too severe
- Proceed with full knowledge and plan for repairs
A survey that reveals problems the seller did not know about can give you a basis for negotiation. Since responsibility for a drain depends on where it runs, read who is responsible for a blocked drain before you negotiate.
What to Look for in a Survey Provider
Check before you book, because a clear report helps you decide. Choose a drainage company that provides:
- Full HD camera footage you can keep
- A detailed written report
- Clear explanation of any issues found
- Recommendations for remedial work
- A clear explanation of any repairs needed
At Emergency Plumber Colchester, we provide pre-purchase drain surveys for homes in Colchester and the surrounding area. Engineers explain what they find, while giving honest advice about any issues. We also cover drain surveys for homes in Manningtree and drain surveys for homes in Brightlingsea.
If a survey reveals damage, we also offer drain repairs including no-dig pipe relining for cracked drains and excavating and replacing a collapsed drain. However, a damp patch or a suspected hidden leak may need leak detection as well. If a drain fails after you move in, follow the steps for emergency drain problems. To keep drains clear, see how drain jetting compares with rods.
