Symptom field note
Animal sounds or nesting material
Scratching, chirping, feathers, twigs or unusual debris appear in or near a chimney.
Keep the appliance off until the flue is confirmed clear and suitable for use.
What might be behind it?
Several conditions can produce similar symptoms. These are possibilities for a professional to investigate, not a remote diagnosis.
An open termination can allow nesting or animal entry, but the species and flue condition need checking.
Removal rules and humane options can vary by species, season and location.
What to document before calling
- When sounds occur and where they are heard
- Safe photos of debris or the cap
- Whether any appliance shares the vent
Take photographs only from a safe position. Avoid roof access, opening a vent or continuing to operate a suspect appliance to reproduce the problem.
Practical next step
Do not light a fire to drive animals out. Ask a qualified service company or appropriate wildlife professional about lawful removal and a subsequent vent inspection.
Describe the symptom first, then ask the company which inspection or service they recommend and why. Request written findings before approving major repair work.
Questions for the company
- Do you work on my fuel and appliance type?
- Which possible causes will your assessment check?
- What areas are inaccessible and how will you document them?
- Will the report include photos, limitations and a separate repair scope?
