CCTV Drain Surveys in London
Choose Drainsmart for CCTV Drain Surveys in London
As CCTV drain surveys are a necessity to see what is going on in the underground pipework, our dedicated surveying teams carry out dozens of investigations each week. With Drainsmart’s CCTV drain survey in London, we include a full written report complete with a summary of our findings and recommendations to return the system to a free-flowing and watertight condition if needed, as well as a detailed computerised drainage layout diagram showing the positions of manholes and gullies, etc. Our plans are well received across a number of professional trades, especially when compared to our competitors' hand-drawn versions which we have found on many occasions do not reflect the actual building or configuration of the system - you can see an example of what you can expect to receive from us here. We will also provide a copy of the video recording if requested.
CCTV Drain Surveys Explained
CCTV drain surveys allow us to look into the drainage system with a small portable camera unit with no disruption to the ground providing there is adequate access, making this the best way to identify problems. This is watched live on site by our experienced engineers and their notes are compiled into a full detailed report by our office team and signed off by a survey manager with a summary explaining the findings and any concerns as shown on our sample page. If there is not sufficient access to the drainage, e.g. a manhole or rodding access point, a small localised excavation or a cut into above ground external pipework may be required to gain entry and we will reinstate the pipework and the surface area upon completion. This will be a last resort as we have TrapJumper cameras which have been designed to bypass gully and WC rest bends however there is the odd occasion it is not successful as it is dependent on the angle of the bends.

Why is a CCTV Drain Survey Required?
When was the last time you thought about your drainage system? Maybe never up until now. The good news is that this is not uncommon. Many customers call Drainsmart because they suspect something is happening with their drains, maybe an odour appearing, slow draining water, damp walls or cracks in the building or rat activity all of which require investigating to decide the best course of remedial action. They are also necessary to obtain information for extensions and Build Over Agreements, regular monitoring for insurance purposes following a claim especially relating to subsidence, or ascertaining the condition of the system for a Home Buyers survey (see below). We also are called out to advise on how to protect the private drainage system from vermin infestation and sealing any points they may be using to escape from. Unfortunately, there is no way of ascertaining the extent of any issues underground without a prior CCTV drain survey in London and as each drainage system and the level of damage discovered is completely different, we are unable to give an estimated cost of any necessary repairs until we have the information this will obtain. "Quick and efficient service by Drainsmart. Would recommend." Jonathan Stevens, as seen on Google Reviews CCTV Drain Survey in London Customer
What can you expect from a CCTV Drain Survey Service from Drainsmart?
The video footage captured during our CCTV camera inspections can be saved onto a DVD or USB hard drive and/or sent electronically after it has been analysed upon closer inspection. A report will then be issued demonstrating a schedule of remedial works should any defects be discovered together with a computerised drawing showing the drainage layout.
Our charge for a CCTV camera inspection of all of the accessible underground drainage at a domestic property is £230.00 plus VAT which allows for 3 manholes, or £245.00 plus VAT for our Architect Package which includes superimposing the drainage layout onto supplied General Arrangement (GA) plans.
Most standard size properties have 1 or 2 manholes and we allow time to inspect a 3rd however any extra chambers found will be charged at an additional £60.00 plus VAT per manhole.
We are also able to inspect larger sites such as blocks of flats and housing estates, schools, churches and commercial premises which are usually based on a day rate – please feel free to contact us for more information.
Home Buyers Drain Survey in London
If you are considering or currently in the process of buying a new home, you should always consider a Home Buyers drain survey. These surveys will inspect the drainage system and make sure there are no current or potential issues with the pipework. If you disregard a Home Buyers survey and there are pre-existing issues, you may find it hard to negotiate with an insurer or the previous homeowner, meaning you may be liable for the damages to your property. A Home Buyer drain survey can locate and identify drainage issues from small blockages to extensive problems.
"I chose Drain Smart based on being registered with he National Association of Drainage Contractors and online reviews, and I feel I made the right decision. The team were really polite, helpful, honest and went the extra mile to help me resolve my problem. They showed me what they were doing, what they had found (thankfully nothing) and ways forward (useful practical day-to-day advice about my drains). They were so thorough on the day that I was able to plan my next steps there and then. The final CCTV report came super quick and is really helpful. Overall, I was very pleased by the service on offer."

Book Your CCTV Drain Surveys Today
We can schedule your appointments over the phone or by email and are happy to liaise with any agents to arrange access if needed. As we have many crews on the road and with a CCTV camera inspection of a standard size domestic property taking around an hour to complete, we can usually attend within 24-48 hours to carry out the investigation.
We are happy to send the footage from the CCTV Drain Survey to you electronically or alternatively we can save the files onto a USB and post this to you. Please note that recordings and/or stills will only be sent if requested and the footage will be kept for a minimum of 6 months.
If there are no manholes or other access points such as a rodding access to allow entry of the camera unit, we will need to breach the system which is usually by cutting into external sections of above ground pipework and/or excavating the gullies. This will allow us to insert the camera into the pipework but is likely to only give limited access to the one drain we have breached and not the rest of the drainage system.
If damage is not addressed, the condition of the drain will only deteriorate over time. Some defects can be in the drainage system for years before they are even identified however they can reach a point where they cause damp or even structural movement and if the damage becomes so severe, the only option to resolve the issue may be replacement of sections of underground pipework and in extreme cases, underpinning of the building may be necessary.
A CCTV camera inspection of the underground drainage system at a property we visited revealed this earthenware pipe is severely fractured and it will be allowing the loss of water into the surrounding ground. As you can see in the video recording from the drainage survey, the fractures are over a long length of the drain and the extent of the water loss could contribute to damp or structural movement. Although the damage is severe and needs to be addressed, this drain could be repaired by structural soft felt lining if there is adequate access to work from. If the access to the drainage system is insufficient, at least one excavation would be necessary to gain access to the underground pipework and we would be able to install structural soft felt liners from this point. Structural soft felt lining would be the better choice over structural patch lining as one sleeve would be able to repair the length of the drain instead of a high number of patches in precut lengths and is therefore more cost-efficient. The client of this particular project did ask if it would be more beneficial to replace the whole length of pipework however as this drain runs under the house, the works would be very disruptive and the costs significantly higher. As structural soft felt liners and structural patch liners have a life expectancy exceeding 50 years, we would always recommend the installation of these over the replacement of drains wherever possible. You will also see that there is a loose piece of broken pipework being pushed along the drain. This will be restricting the free flow of waste and could cause an overflowing blockage. We recommend removing this using a Picote Mechanical Grabber followed by high-pressure water jetting to flush through the remaining debris deposits.

Reviews from Drainsmart Customers
Below are some of the drain repairs reviews we have had from Drainsmart customers.
"This was an urgent short notice request to complete and report on a CCTV drain survey in connection with a property purchase in Wimbledon following on from a Building Surveyor's recommendation. Drainsmart could not have been more understanding and helpful throughout. They fitted the survey at short notice, completed it with minimal disruption for the current property owner and sent me a high quality (and - important for a lay person - readily digestible) report on the same day which enabled us to exchange contracts the following week. We will now do the work recommended."

"Drainsmart had perfect customer service. They were efficient, polite and when things didn’t quite go to plan (an equipment failure totally out of their control) they dealt with it in the perfect way.
They got in touch, rebooked at my convenience and expedited the report free of charge. I love companies with customer service like this.
I will always recommend you Drainsmart for my experience! Thanks!!"

"Having major renovation done SW14 , so was advised to get drain survey done by our architect.
These guys came highly recommended and arrived promptly and were very polite and efficient.
Drain survey turned up interesting things a crack pipe and neighbours surface water running down our side . Well worth getting it done early into project as helps to prepare for future work.
Would recommend this company to anyone.
