Rats rarely appear without a cause. We combine humane treatments with drain expertise to remove infestations and prevent re-entry. From CCTV drain surveys to non-return valve installation, we tackle the root cause—not just the symptoms.
When to Suspect a Drain Issue
Recurrent rat activity after standard treatments
Activity near kitchens, bathrooms or soil stacks
Manholes showing evidence of rats
Older properties with redundant or shared lines
What We Do
Initial assessment — internal/external checks and manhole inspection
CCTV survey — locate breaks, open connections or rat runs
Report & recommendations — clear summary with images/video where available
Non-return valve installation — sized and positioned to maintain normal outflow
Follow-up — re-inspection and liaison notes for any drainage repairs
Benefits
Root-cause fix for rat ingress
Minimal disruption—most NRVs install without excavation
Works alongside humane trapping to clear residual activity
Clear documentation for landlords, insurers and maintenance teams
