Here at Drainsmart, we are fully equipped to carry out all types of repairs to your drainage system, investing in the latest technology on a regular basis to keep us ahead of the game and for you to avoid high costs and disruptions when trickier remedial works are needed.


The preferred method in the industry remains drain sleeving (where possible) which involves installing a structural soft felt liner from available access points such as a manhole or, on occasion, we may need to make a small localised excavation to breach the underground system. Once pertinent information has been obtained following a CCTV camera inspection, such as the diameter of the pipe, the most suitable type of sleeve is cut to size depending on the length of the drain and once the process is complete and it has been cured in place, the damaged pipework is returned to a watertight condition.

The installation of drain sleeves used to be slightly restricted as structural soft felt liners could only be installed in straight sections of pipework and structural patch liners could not be positioned beyond bends however with the development of super-flex liners, Brawoliners and Picote Cannon liners, all of which we can install, there are not many instances where sleeving is not possible. They can now also be inserted into a run which has branch or lateral connections as with our Dancutter lateral cutting machinery, we can cut into the sleeve and reopen the junction, leaving the connecting pipework fully operational.

Not only can these repairs be carried out to the underground drainage system, we can also install liners into the internal vertical pipework running from the roof if safe and flat access is available, which saves knocking holes into walls and redecorating afterwards. This is particularly cost efficient in blocks of flats where the downpipes pass through 5 or 10 floors where the pipework would be boxed in, potentially behind tiles, bathroom suites or kitchen units, etc. which would obviously require considerable reinstatement.

Apart from the benefit of minimal disruption as lining removes the need to excavate and replace the pipework, it is far more time efficient and cost-effective than renewal and with its life expectancy exceeding 50 years, it is the obvious choice.

Comments from Drainsmart customers

Below are some of the reviews we have had from Drainsmart customers.

“Drainsmart were incredibly accommodating and helpful. We requested the above urgent works and they managed to book in both appointments within a 24-hour notice. Following the inspection, they produced the survey reports the very next day therefore super-efficient and cooperative. Cost wise they were also very reasonable. As an architect, I would highly recommend their services for drainage surveys on new projects as well as potential homebuyers. Both the admin team and Tony Marsh the contracts manager were extremely friendly and a great reminder of how customer service should be. Thank you.”
