  • What are CCTV Drain Surveys?
    A CCTV Drain Survey or CCTV Camera Inspection involves a small portable camera unit being inserted into the drainage system which allows us to see inside the underground pipework and report on our findings. There are many reasons for investigations and we tailor our reports to each individual property. Find out more about CCTV Drain Surveys.
  • Are your computerised drawings to scale?
    Our drawings are not to scale and are for indicative purposes only however we can superimpose the drainage layout onto supplied architect GA plans for more accurate reading. Dependant on the access available, it is not always possible to determine the route or configuration of the drainage system and an assumption may be made based on our findings but this can be confirmed with electronic sonde tracing.
  • Do you provide the depth of the pipework?
    The survey does not include invert levels back to a datum but we will provide you with the invert depth of each chamber in millimetres which you could add to your levelling survey.
  • Do Drainsmart provide drain cleaning services?
    If so, how long does a blockage clearance or high pressure water jetting take? Unfortunately we cannot put a time frame on this as it is all dependant on the level and type of deposits found. A standard domestic blockage can usually be cleared within one hour but we cannot guarantee this and will not be able to know until we have the jetting hoses in the system and start moving the deposits. Find out more about this here.
  • I require drain repairing, can you help? How much do repairs cost?
    As each drainage system and the extent of damage which dictates the schedule of remedial works is completely different, this could drastically vary. Once we have carried out a CCTV camera inspection, we will provide you with a quotation for the remedial works but until further information has been obtained we will not provide a ball park figure. Learn more about drain repairs.
  • How long do your repair works take to complete?
    Again, this is dependant on the level of damage that was discovered and the remedial works that are instructed which could vary from a couple of hours to a couple of weeks. Where possible, we will try to send multiple crews specialising in different aspects of the trade to try to keep time on site to a minimum but this is not always practical.
  • Can you work on Thames Water sewers?
    Following the “Transfer of Sewers” Act in 2011, private contractors are not permitted to work on any Local Water Authority’s drains without their full permission, excluding CCTV surveys. It is common for these assets to run through your property and even if you are willing to pay for the necessary repairs, any contractor found to carry out work to these sections will be heavily fined and therefore we will not proceed without confirmation of their written consent.
  • Who do Drainsmart provide drainage services in London for?
