What should Airbnb hosts do when a guest reports mold or mildew?

01

Start with location and photos

Ask the guest where they see or smell the issue and request photos if they are comfortable sharing them. A note that says 'mold in the bathroom' is not enough to decide the response. The concern could be shower grout mildew, a wet bath mat, a vent issue, a leak, a musty basement smell, or something that needs a professional look.

• Ask for the room, surface, and approximate size of the concern.
• Request a photo before sending the cleaner if the guest is willing.
• Check whether moisture, leak history, poor ventilation, or standing water is involved.
• Keep messages calm and avoid diagnosing the issue in writing before you know what it is.

02

Separate routine mildew from possible mold

Small bathroom mildew on grout or caulk may be a cleaning and ventilation issue. Larger visible growth, recurring musty odor, water stains, soft drywall, active leaks, or guest health symptoms should not be treated as a normal turnover task. The host may need maintenance, inspection, or remediation before accepting the next booking.

03

Fix moisture before asking cleaning to carry the problem

Cleaning alone does not solve an active moisture source. If the cause is a leak, poor ventilation, wet carpet, damp basement, or failing caulk, the same complaint may come back after every clean. Handle the source first, then use cleaning to reset surfaces, remove ordinary residue, and prepare the home after the condition is corrected.

04

Use cleaner photos for documentation

If the cleaner can safely inspect the area, ask for clear photos before and after cleaning, plus notes about odor, moisture, stains, ventilation, and whether the issue looks outside normal cleaning scope. This helps the host decide whether to re-clean, block the calendar, call maintenance, or respond to the guest with facts.

05

Do not overpromise the same-day fix

A same-day turnover may not be enough if the concern involves moisture damage or significant growth. It is better to block time, fix the source, and document the result than to rush the next guest into a property that may still smell musty or show the same concern. Cleanliness and property condition have to work together.
