Bird excrement removal and decontamination - done safely, and stopped from coming back
Pigeon and starling waste in roof spaces, plant rooms, carparks, warehouses and facades carries histoplasmosis, salmonella and corrosive acids. SES removes it under respiratory controls, decontaminates the surfaces and installs proofing so the birds move on.

- Respiratory-protected removal
- Decontamination and deodorising
- Bird-proofing included on request
Where the problem builds up
Dried droppings become airborne when disturbed - which is why maintenance staff should not clean it themselves.
Roof voids and ceilings
Roof voids, ceiling spaces and warehouse rafters where roosts go unnoticed for years.
Carparks and ledges
Carpark beams, ledges and balconies above vehicles and walkways.
Plant and HVAC
HVAC plant, solar arrays and gutters where droppings corrode equipment and block drainage.
Facades and signage
Facades, signage and building entries where staining and odour are first noticed.
How removal runs
- Step 01
Inspect and quote
Extent, access and the species involved; fixed price including proofing options.
- Step 02
Contain and remove
Area isolated, droppings wetted and HEPA-vacuumed or scraped under respiratory protection, waste bagged.
- Step 03
Decontaminate
Surfaces disinfected and deodorised; corroded or damaged materials reported.
- Step 04
Proof
Spikes, netting, wire or mesh installed so the roost is not re-established.

Why building owners use SES
Guano is a health-and-safety job, not a cleaning job - and the proofing is quoted with the clean so you pay once.
- Health-and-safety compliant - respiratory controls, containment and hazardous-waste disposal, not a broom and a bin bag.
- Related hazards covered - roof spaces often reveal asbestos insulation or lead paint; our licensed crews handle it on the same job.
- Fixed, not just cleaned - proofing is quoted with the clean so the cost is not repeated next year.
Bird excrement FAQs
Straight answers to the questions procurement teams, facilities managers and property owners ask us most. If yours is not here, call the office or send us the scope and a division lead will answer it directly.
Is bird excrement actually hazardous?
Yes - dried droppings carry fungal spores (histoplasmosis, cryptococcosis) and bacteria, and the acids damage paint, steel and stone.
Can my cleaner or handyman do it?
Small fresh deposits, perhaps. Accumulated or dried guano should be removed under respiratory protection and containment.
Do you remove the birds?
We do not trap or harm birds; we remove the mess, decontaminate and install proofing so they roost elsewhere.
Can you work at height?
Yes - EWP, scaffold and rope-access arrangements as the site requires.
Which regions?
Auckland, Waikato, Northland, Hawke’s Bay and Wellington.
