Septic tank & drainage repairs in Cornwall
When an off-mains system goes wrong it rarely picks a convenient moment. We diagnose and repair septic tanks, treatment plants and drainage fields across Cornwall — from a one-off blockage to a failed soakaway.
Problems we fix
Backing up and slow drainage — often a full tank or a blocked outlet, sometimes a failing drainage field.
Smells — usually a venting, seal or maintenance issue, occasionally a sign of a bigger problem.
Failed or waterlogged drainage fields — assessment, repair or replacement to standard.
Treatment plant faults — pumps, blowers, alarms and electrics.
Diagnose before you dig
A backing-up system isn’t always a broken one — very often it just needs emptying and a proper look at the outlet. We start with the cheapest likely cause and only recommend groundworks when they’re genuinely needed.

Common questions
My drains are backing up — what should I do first?
Stop adding to the system (limit water use), and get the tank checked and emptied. Very often that clears it; if not, it points to a drainage-field problem that we can then assess.
