How often should carpets be professionally cleaned?
The honest answer depends on your household, not a fixed rule — but there are genuine guidelines worth knowing, including a Manchester-specific factor most advice ignores.
General guidelines by household
Standard household
Every 12 months, or 6–9 months given Manchester’s humidity specifically.
Pets or children
Every 6–9 months — higher soiling and accident risk means more frequent attention pays off.
Allergy sufferers
Every 3–6 months — dust mite and allergen build-up directly affects symptoms.
Why Manchester specifically needs more frequent attention
Manchester’s humidity holds between roughly 79–89% year-round, with rain on around 161 days a year. That combination means carpets here dry more slowly after everyday spills and muddy shoes, and hold onto moisture — and the odours and mould risk that come with it — longer than in drier parts of the country. A generic 12-month guideline built for a drier climate genuinely doesn’t account for this.
