Use an autumn entry-point check to create a repair list before weather and seasonal works reduce access. Inspect doors, service penetrations, waste areas, ground-level fabric and roof edges from safe positions, while keeping ventilation and other building functions intact.
Walk one route around the building
Start at loading and resident entrances. Record damaged door sweeps, thresholds and doors that do not close. Continue around pipes, cables, basement openings, bin stores, vegetation, sheds and accessible drains. BPCA mouse guidance identifies gaps around pipes, windows and basements among areas to inspect and describes proofing as part of prevention.
Then review higher features from the ground: eaves, soffits, vents and displaced coverings. Do not climb, open chambers or enter unsafe lofts for a seasonal checklist. Mark areas requiring a roofer, drainage contractor or access specialist.
Photograph each concern with a location code and overview. Keep observed pest evidence separate from the building opening. A gap is a possible route, not proof that mice are using it.
Do not seal the building’s functions
Identify air bricks, grilles, ducts and drainage paths before specifying proofing. GOV.UK Approved Document F provides statutory ventilation guidance in England; the applicable detail depends on the building and work. Refer ventilation, fire, drainage and structural questions to the competent person responsible for that system.
Agree closure timing where activity may already be inside. Track the action by trade, target date and verification. Do not use autumn as a reason to rush an unassessed filler into every opening.
Add operational checks
Review waste capacity, food storage, delivery doors and vegetation management alongside fabric. Set an earlier follow-up after storms, building works or a damaged door rather than waiting for next year.

FAQs
Should every visible gap be sealed?
No. Identify its function, evidence and competent repair first.
Can the check be done from ground level?
Many observations can, but record roof and concealed areas that need separate safe access.
Is autumn the only useful time?
No. Also review after repairs, storms, changes in use and new evidence.
