Where pigeons roost, droppings accumulate fast: on balconies and window ledges, in lofts and plant rooms, under solar panels and across flat roofs. Mixed with feathers, nesting material and dead birds, the build-up becomes a serious hygiene problem.
Dried guano breaks into fine dust that is easily breathed in when disturbed. That is why we don’t recommend sweeping it up yourself. Our team works in full protective equipment and follows a controlled process from start to finish.
What to look for
- White and grey crusted deposits on ledges, sills and roof areas
- Feathers, nesting debris or dead birds in lofts, voids or plant rooms
- A strong ammonia smell in enclosed spaces
- Stained or eroded stonework, render and paint below roosting points
- Blocked gutters, outlets and downpipes
Why guano needs a professional clean
Bird droppings can harbour fungi and bacteria linked to illnesses such as histoplasmosis, cryptococcosis and psittacosis, which are contracted by breathing in contaminated dust. Guano also attracts secondary pests such as bird mites, carpet beetles and flies.
Its acidity damages roofing, metalwork, stone and paint, and wet guano on walkways and fire escapes is a genuine slip hazard and a health-and-safety liability for businesses.
How we deal with it
Risk assessment
We assess access, quantity and hazards, and plan safe working, including access equipment for roofs and heights.
Controlled removal
Deposits are dampened down with a biocide to suppress dust, then scraped and bagged by operatives in respirators and disposable coveralls.
Sanitise
All affected surfaces are disinfected to kill remaining bacteria and fungal spores and to neutralise odour.
Disposal & proofing
Waste is removed and disposed of through licensed channels. We then recommend proofing so the birds can’t return.
Keeping it from coming back
- Proof roosting areas with netting, spikes or wire once cleaned.
- Clear gutters and outlets regularly on buildings with bird activity.
- Book scheduled cleans for commercial sites with ongoing pressure.
- Fit solar panel mesh to stop debris building up under arrays.
