National Association Drainage Contractors

Our NADC Membership Ensure You Get the Best Service

When your drainage goes wrong, it can be very inconvenient; blockages, gurgles, slow water draining or bad smells can all make it very inconvenient for you. The best way to get rid of the issue(s), is to call in an NADC certified expert.

If you are in need of a drainage contractor to carry out drain unblocking, drain cleaning or drain descaling, be sure to only use an NADC certified member company.

Here are some of the reasons to have a drain survey carried out by a certified drainage surveyor on a property you are buying or selling.

AN NADC C-D-S (Certified Drainage Surveyor) will provide you with easy to read and understand reports which will include:

  1. Structural Condition Reporting/analysis
  2. Mis-connections identification and reporting
  3. Drainage system ownership - Private / Water Company
  4. Mapping - drawing to show drainage system locations and components
  5. Mortgage lenders may/will request a drain survey, Insurance company may/will request a drain survey. These reports will satisfy all parties including solicitors for CON29DW’s (Water Searches)

  7. Water company could be for-warned about defects on there asset, saving time and money on repairs and preventing the buyer from inheriting problems
  8. Most RICS building surveyors do not carry the equipment to carry out an in-depth survey to a critical part of the structure, everything else can be properly inspected apart from the drainage system.
  9. Buyers are often left in the dark about the condition of drains which are often out of sight, out of mind and can often be in a very poor condition.
  10. Insurance companies are often covering defective drainage as they are unaware of the true condition, a growing number now request a drain survey before offering cover.
