Ideal Home’s report identifies five everyday clues that may point to excess moisture at home: persistently wet windows, recurring mould, musty smells, slow-drying laundry and humidity readings regularly above 60%. Experts quoted in the report say a dehumidifier can help lower airborne moisture, but it will not resolve leaks or other sources of water ingress.
Ideal Home has outlined five signs that a home may have excess moisture and could benefit from a dehumidifier, citing expert advice on recurring condensation, mould, musty smells, slow-drying laundry and humidity readings. The report says a dehumidifier may help control moisture in the air, while stressing that it cannot repair a leak or other building defect causing damp.
The first clues are windows that repeatedly become wet and mould returning around frames, cold corners or behind furniture. Meaco co-founder and air-treatment expert Chris Michael says condensation forms when moist air meets a cold surface. Wiping the glass removes water from the pane, he says, but does not reduce moisture in the air. The report advises keeping sills dry and using extractor fans while cooking and showering.
A persistent musty smell, including in wardrobes or cupboards, can also be a reason to investigate, even if mould is not visible. Michael advises checking behind furniture and in enclosed storage spaces. Ebac director Pamela Petty adds that furnishings feeling damp, warped window ledges, peeling paint or wallpaper, and sticking doors can accompany excess moisture.
The other signs are laundry taking unusually long to dry indoors and humidity readings that repeatedly exceed 60%. Michael recommends checking readings over several days, rather than relying on a measurement taken just after a shower, and suggests about 55% relative humidity as a target for UK homes. Drying times also depend on temperature, airflow and how clothes are spaced on an airer.
When Indoor Moisture Becomes a Problem
Recurring dampness can be more than a daily inconvenience: it may indicate that moisture is accumulating in parts of the home where ventilation is limited or surfaces are cold. Identifying the source matters because an appliance can reduce airborne moisture, but treating symptoms alone may leave the underlying problem in place.
The report’s guidance offers practical indicators to check before buying equipment. A hygrometer can help establish whether humidity stays high, while checking cupboards, furniture and window frames may reveal areas that need attention. A dehumidifier may be useful when moisture from ordinary activities such as showering, cooking or drying clothes is difficult to clear through ventilation.

How Household Moisture Builds Up
Cooking, showers and indoor laundry all release water vapour. In autumn and winter, the report says, windows may remain closed for longer, making it harder for that moisture to escape. It can then settle on colder surfaces, including windows and areas behind furniture.
The report draws on advice from Chris Michael of Meaco and Pamela Petty of Ebac. Their comments distinguish signs that may be associated with excess humidity from proof of a particular cause: condensation and musty odours are clues to investigate, not a diagnosis of why damp is present.

Signs Do Not Identify the Source
The five clues do not confirm that a dehumidifier is the right solution in every case. Persistent damp may result from a leak, roof problem or water entering through damaged walls, and the report says a dehumidifier will not fix those causes. Damp concentrated in one place should be investigated rather than treated only by lowering indoor humidity.
The source material does not provide a study establishing how often these signs indicate high humidity, or a universal humidity threshold for every property. Readings can vary by room and circumstances; the report advises checking over several days and not treating a single post-shower result as representative. It also does not give a publication date or details of any follow-up research.
Check, Ventilate and Investigate
Homeowners noticing these signs can start by checking humidity over several days, airing rooms where practical, using extractor fans during cooking and showers, and allowing air to circulate around furniture. If drying clothes indoors, leave space between garments and follow the dehumidifier maker’s instructions if using a laundry setting.
If mould keeps returning, damp is localised, or there are signs of water damage, investigate the cause and address existing mould rather than relying on a dehumidifier or masking odours. The report gives no timetable for further guidance; the appropriate next step depends on the home’s readings and whether a building defect is suspected.
Key Questions
What are the five signs listed in the report?
They are recurring wet windows, mould appearing around windows or behind furniture, a persistent musty smell, slow-drying indoor laundry, and humidity readings regularly above 60%.
Does a dehumidifier fix leaks or water ingress?
No. The report says a dehumidifier may reduce moisture in the air, but it will not repair a leaking pipe, roof problem or damaged wall that is allowing water into the home.
What humidity level does the report recommend?
Meaco’s Chris Michael recommends about 55% relative humidity for UK homes. The report says repeated readings above 60% may indicate excess moisture and advises checking over several days.
Can one high hygrometer reading confirm a problem?
No. The report advises against relying on a single reading, particularly immediately after a shower. Check humidity across several days and consider other signs and possible causes.
What should I do if mould or damp keeps returning?
Look for the cause, especially if damp is concentrated in one area, and deal with existing mould. The report recommends checking less visible places, including behind furniture and inside cupboards, rather than simply covering a musty smell.
