CCTV Drainage Surveys in Harrow
Need drainage certainty before breaking ground in Harrow? Our CCTV drain surveys provide accurate, non-invasive inspection of underground pipework — essential for risk management, compliance and confident project planning.
We use HD crawler cameras to capture internal footage and deliver precise data on condition, pipe diameter, invert levels, discharge type and flow direction.
With every survey, you’ll receive:
- A detailed PDF report with defect grading and location mapping
- High-resolution video and still imagery
- An indicative connectivity sketch as standard
- CAD deliverables available when paired with topo or measured building surveys
Ideal for build-over approvals, legacy site mapping and pre-construction due diligence across the Harrow area.

Our clients in Harrow typically call us when:
- Buying or selling property — to avoid nasty (and costly) surprises.
- Planning extensions or renovations — ensure your drains are suitable before building.
- Facing recurring blockages or flooding — identify the root cause and location.
- Post-subsidence or movement — verify that underground pipework hasn’t shifted or collapsed.

Reviews
Terrain Surveys Ltd have carried out a first class service of locating a drain pipe under my garden. Particular praise must go to Gareth and Euan, the onsite operatives who performed a first class survey on an extremely hot day. Consideration and care was exercised in my and my neighbours garden. Praise must also go to Sue in the office. All requests and questions were quickly responded to. Thank you.
