A pre purchase drain survey helps establish buried drainage condition before a property transaction is committed. We inspect the agreed accessible runs and explain findings that may affect maintenance or repair costs. An early survey leaves time to clean, trace or re-inspect any section the camera cannot reach on the first visit.
Pre Purchase Drain Survey
Pre purchase drain surveys to identify visible drainage defects and inspection limits before a property transaction.

What a buyer needs to know
Inspection limitations matter to a buyer as much as the defects shown in the footage.
Interpreting the findings
The findings should separate confirmed repair needs from areas requiring further access or investigation.
What the survey can establish before purchase
The survey can identify visible cracking, root entry and displaced joints, alongside deposits that restrict inspection. The report locates each finding and records whether cleaning or tracing is needed. A camera video alone does not establish legal ownership, the location of every service or the watertightness of every joint.

Understanding the survey findings
We distinguish visible defects from areas that need further checks, and uninspected pipework remains marked as uncertain. A recent clearance does not establish the condition of the whole drainage system.
Allowing time for further inspection
Restricted access or heavy deposits can leave an initial survey incomplete. Cleaning or tracing may be needed before the report can cover the intended area. Repair advice is based on observed damage, not an assumption that hidden sections match the visible ones.
Pre Purchase Drain Survey: common questions
Is this normally part of a building survey?
A building survey does not automatically include an internal drainage survey. Its agreed coverage needs checking.
Can it confirm whether drains are shared?
Physical connections may be identified, but ownership also depends on property information and sewerage arrangements.
Should it happen before exchange?
Where the findings could affect the purchase, allow time before exchange for the survey and any necessary further checks.
Can a buyer arrange a survey after an offer is accepted?
Yes, subject to access arrangements. Earlier investigation leaves more time to resolve drainage questions.
Is a recent unblocking receipt a condition report?
No. Clearance confirms work on an obstruction, not the condition of every buried run.
