There are 2 parts to rat proofing…
Stopping them coming into your living areas
this means you will no longer see them, find droppings and they can’t contaminate foods/food preparation areas but they will still be able to access wall voids, floor voids etc.

Stopping them accessing the building fabric
this means you will no longer hear them and they won’t be able to damage pipes, electricals etc.

1. Proofing internally to stop rats getting into living areas
Rats are notoriously active gnawers with teeth that measure 5.5 on the Mohs scale of hardness – this means aluminium, copper, iron, brick & cement are all passable given time and intent.
We base our proofing on steel – this comes in the form of various flexible and rigid meshes and is secured in place with hot melt and/or silicone adhesives.
We also have all of the specialist tooling and access equipment to remove appliances (even where they’re integrated) and so we can not only find these concealed entry points, we can get to them too – all without removing the kitchen units!
All rooms within a property are considered when we proof internally – just doing the kitchen won’t stop them popping out somewhere else.
2. Stopping rats accessing the building fabric
We’ll always survey to address this aspect as it’s impossible to accurately diagnose over the phone and our own CCTV drain inspection is always part of this assessment.
Should drainage defects be confirmed via CCTV, our operatives are trained pipe patch repair installers allowing us to fix minor pipe defects using internal resin patches without having to excavate – this saves a lot of money and disruption if the defect is under your extension!
Sometimes the defect cannot be easily repaired and the only option is to install a one-way valve so as to stop rats reaching the defect whilst still allowing waste to pass through to the sewer. We only fit Danish made units – Pipesec & Nordisk valves are our chosen brands as the twin serrated flap design is VA-approved and 100% successful at stopping rats’.
Where rats are accessing via above ground routes, we can mesh proof/cement proof all such areas using materials and methods that can’t be by-passed.
All our work is comprehensively photographed and detailed so as to provide full auditability into the process – useful if you wish to try and recover costs from house insurance, landlords etc.
