Pest Proofing &
Exclusion Works
Treating a pest problem removes the infestation — but without proofing, they come back. Our exclusion works permanently seal the entry points that rodents, birds, and insects use to access your property.
Why Proofing Is the Permanent Solution
Pest treatments are highly effective, but they address the symptom — not the cause. If a rat can squeeze through a gap under your door frame, or mice are entering through an unprotected air brick, the problem will return within weeks of treatment.
Pest proofing is the process of identifying and permanently sealing every entry point a pest could use. Combined with a treatment programme, it breaks the cycle of reinfestation and gives you lasting protection.
Our RSPH-qualified technicians carry out a thorough survey of your property, identify all vulnerabilities, and install professional-grade exclusion materials that are far more durable than DIY solutions.
Rat Entry Points
Gaps as small as 20mm — the size of a 50p coin — are enough for a rat to enter.
Mouse Entry Points
Mice can squeeze through a gap of just 6mm. Air bricks, pipe runs, and gaps around cables are common entry points.
Bird Entry Points
Roof voids, soffits, and broken fascia boards provide ideal nesting sites for starlings, sparrows, and pigeons.
Insect Entry Points
Wasps, ants, and cockroaches exploit cracks in masonry, gaps around window frames, and poorly sealed utility penetrations.
Our Proofing & Exclusion Services
Air Brick & Vent Covers
Stainless steel mesh covers fitted to all air bricks and vents to prevent rodent entry while maintaining airflow.
Gap & Crack Sealing
Professional-grade sealants and expanding foam used to fill gaps around pipework, cables, and structural penetrations.
Door Brush Strips
Heavy-duty brush strips fitted to external doors to eliminate the gap at the base — a primary entry route for mice and rats.
Mesh & Wire Wool Filling
Rodent-resistant stainless steel mesh and wire wool used to fill larger gaps that sealant alone cannot address.
Roof & Soffit Proofing
Inspection and sealing of roof voids, broken fascia boards, and soffit gaps to prevent bird and rodent nesting.
Drain & Pipe Proofing
Rat flaps and pipe collars fitted to drainage systems and soil pipes — a common but overlooked entry route for rats.
Commercial Exclusion Works
Full perimeter surveys and exclusion programmes for commercial premises, warehouses, food businesses, and agricultural sites.
Post-Treatment Proofing
Proofing carried out as part of a treatment programme to prevent reinfestation after rodent or insect treatments.
Proofing Survey & Report
A standalone survey identifying all vulnerabilities, with a written report and quotation for exclusion works — ideal for landlords and property managers.
Our Proofing Process
Initial Survey
We carry out a thorough inspection of the interior and exterior of your property, identifying all actual and potential entry points. We check roof lines, foundations, utility penetrations, doors, windows, and drainage.
Written Report
You receive a clear report detailing every vulnerability found, the risk level of each, and our recommended exclusion works — with a fixed-price quotation.
Exclusion Works
Our technicians install professional-grade exclusion materials at every identified entry point. We use stainless steel mesh, wire wool, expanding foam, door brush strips, and drain rat flaps as appropriate.
Post-Works Inspection
We inspect all completed works before leaving and provide you with a completion certificate. For commercial clients, we can provide documentation suitable for audit and compliance purposes.
