CCTV Drain Survey South East London — Identify Hidden Blockages
South East London Blocked Drains provides CCTV drain surveys for pre-purchase inspections, build-over agreements, and diagnosing persistent blockages across South East London. Full written report and HD footage included. Call 07723363092.
When a drainage problem keeps returning, guessing the cause is a waste of time and money. A CCTV drain survey eliminates the guesswork, allowing us to see exactly what is happening underground without any disruptive excavation. According to the Royal Institution of Chartered Surveyors (RICS), drainage defects are among the most commonly missed issues in standard homebuyer surveys — a dedicated drain survey costs a fraction of the remedial work if a collapsed drain is discovered post-purchase.
Crucial for Home Buyers in SE London
If you are purchasing a property, especially older Victorian terraces in areas like Forest Hill, Catford, or Nunhead, a pre-purchase drain survey is highly recommended. Standard structural surveys rarely cover the condition of underground drainage. Replacing collapsed drainage can cost thousands of pounds.
Our comprehensive surveys identify root ingress, fractures, displaced joints, and collapses before you exchange contracts, empowering you to negotiate repairs into the purchase price.
When Do You Need a CCTV Survey?
- Pre-Purchase Inspections: Ensure you aren't inheriting costly drainage liabilities when buying a new home. According to RICS, drainage defects are among the most commonly missed issues in standard homebuyer surveys.
- Build-Over Agreements: Bromley and Lewisham planning departments often require surveys if you are building an extension over or near existing sewer lines. We provide the survey and report needed for planning applications.
- Recurring Blockages: If your drain blocks repeatedly despite clearance, there is likely a structural defect. A CCTV survey identifies the exact cause and location.
- Rodent Investigations: Rats often enter properties through compromised drainage infrastructure. A survey identifies entry points so they can be sealed.
- Subsidence Checks: Leaking drains can wash away soil, causing property subsidence over time. A survey identifies leaks before they cause structural damage.
What You Receive
Following our inspection, you receive a full digital package. This includes high-definition video footage of the drain interior, alongside an industry-standard written report detailing every defect found, its location, and a no-obligation quote for any necessary remedial works, such as patch lining or excavation.
Our CCTV Survey Process
- Pre-Survey Consultation: We discuss your concerns and identify the drains to be surveyed. We'll advise if jetting is needed first for visibility.
- On-Site Survey: Our engineer inserts a HD CCTV camera into the drain, recording footage as it travels through the pipe. The survey takes 1-2 hours for a standard domestic property.
- Real-Time Analysis: As the camera travels, we identify and log every defect — cracks, root ingress, collapses, displaced joints, and more.
- Report Delivery: Within 24 hours, you receive the HD footage and a written report with defect locations, severity ratings, and recommended remedial works.
- No-Obligation Quote: If remedial work is needed, we provide a fixed quote. You're under no obligation to proceed with us for the repair work.

Frequently Asked Questions
Why do I need a CCTV drain survey before buying a house?
Drain repairs can cost thousands. According to RICS, drainage defects are among the most commonly missed issues in standard homebuyer surveys. A pre-purchase survey identifies structural defects, root ingress, or collapses before you complete the purchase, allowing you to renegotiate the property price.
Do I get a copy of the footage?
Yes, we provide full HD video files along with a comprehensive written report detailing any defects and recommended remedial works.
Will a survey help if I'm planning an extension?
Absolutely. Local authorities like Bromley and Lewisham often require a 'build-over' survey if you are extending near or over existing drainage infrastructure. We provide the survey and report needed for planning applications.
How long does a CCTV survey take?
A standard domestic survey usually takes between 1 and 2 hours on-site, with the report delivered within 24 hours. Complex or commercial surveys may take longer.
Can cameras see through dirty water?
If a drain is completely blocked with standing water, we usually need to perform a high-pressure jetting clearance first to ensure visibility for the camera. We'll advise you on this when you book.
How much does a CCTV drain survey cost?
A standard domestic CCTV drain survey costs between £120 and £280 depending on the complexity and length of the drain run. We provide a fixed quote before any work begins.
