Your property brief
Pest Proofing
Recurring activity near doors, service penetrations, damaged screens or gaps around the building calls for a proofing assessment. The relevant opening depends on the pest and the route it uses. Sealing the first visible gap may leave connected voids or another entry point untreated.
Discuss this service
What the service can include
Work includes inspecting the affected areas, identifying entry routes and defining suitable barriers, repairs or alterations. The scope describes the materials, location and finish, along with cleaning or active-control work needed beforehand. Records show completed areas and any inaccessible or unresolved route.
We provide every service in our catalogue, including the individual services within each trade, for all sectors and locations listed on this website. Tell us what your property needs so we can agree the work, access and timing.
What to consider
Proofing must suit the building's other functions. Ventilation, drainage, fire protection and access for servicing must remain effective. A gap around a service may need a designed repair rather than an improvised seal, particularly where the opening forms part of a protected building element.

A closer look at the property brief.
The work starts with the property.Before we visit
Provide the address, photographs and the areas where activity has been observed. Identify shared walls, roofs or service voids and confirm permission for exterior work. Agree the expected finish and any need to access neighbouring spaces.
How we help
The survey connects activity with likely routes and defines the appropriate repairs. Work is sequenced with any active-control requirement, then recorded by location. Handover identifies remaining observations and the maintenance needed to keep doors, screens and barriers effective.
What affects cost and timing
The number and type of openings, access, substrate condition and specialist building interfaces affect price. A door adjustment differs from work in a roof void or service riser. Include preparation and making good so the repair is complete and durable.
Property and sector applications
Managing agents need responsibilities and approvals connected to the correct owner. Residential blocks need communal and individual areas distinguished.

Frequently asked questions
Does proofing remove an existing infestation?
Not by itself. Active pest control and the sequence of closing routes may need coordination.
Can every gap be filled with the same material?
No. The pest, building function, exposure and surrounding construction determine a suitable detail.
Why do repaired buildings still need monitoring?
New damage, open doors, deliveries and alterations can create fresh routes. Monitoring helps identify changes.
Will repairs affect decorative finishes?
Agree the required finish, access openings and reinstatement in the quotation so the owner knows what the completed work includes.
