What to do about persistent bad smells in a home

A smell that returns after cleaning is information, not simply a reason to add more fragrance. The source may be textiles, drains, humidity, waste or a hidden property issue.

Professional Safety Note

Stop and leave the area if there is a gas-like smell, sewage, smoke, chemical fumes, dizziness or an immediate health risk. Do not mix products, open pipework or use fragrance to conceal a potentially dangerous source.

This guide provides general advice. For structural or electrical issues, always contact a certified professional and follow the property’s agreed access and communication plan.

Describe where and when it happens

Identify the room, surface or fixture, whether the odour is stronger after rain or a long closure, and whether it follows cooking, occupancy or use of water. This record is more useful than a general report that the home smells.

  1. Ventilate safely and keep children, guests and pets away from a suspect area.
  2. Check accessible bins, soft furnishings, drains and visible damp marks without dismantling anything.
  3. Photograph visible staining and record changes for the owner or qualified professional.

Clean the source you can safely reach

Wash or remove accessible textiles, bins and surfaces according to their care instructions. Give fabrics and rooms enough time to dry before deciding whether the odour has gone.

Repeated deodorising can mask a drain, moisture, waste or ventilation problem. Persistent odours should be escalated rather than treated with stronger chemicals.

Turn an observation into a service plan

A deep and seasonal cleaning visit can address agreed accessible areas, while property support or villa maintenance can help document the symptom and coordinate the right trade when the source is not a cleaning issue.
