Our carpet cleaning technicians are trained in NCCA (National Carpet Cleaners Association) standards and work with all carpet types including wool, polypropylene, nylon and natural fibres.
The Short Answer
Most households should have carpets professionally cleaned every 12–18 months. Households with children, pets, allergy sufferers or high footfall should clean every 6–12 months. This is not just about appearance — a carpet that looks clean can still harbour significant levels of allergens, bacteria and dust mite waste deep in the pile where a vacuum cannot reach.
Factors That Affect How Often You Should Clean
Pets
Pet dander, hair and tracking-in of outdoor soil dramatically accelerate the accumulation of allergens and odour-causing bacteria in carpet fibres. Households with pets should clean every 6 months as a minimum, and consider a fabric protection treatment after each clean to reduce absorption.
Children
Children spend more time on the floor than adults and are more susceptible to allergens. Spills, food residue and playground soil brought in on shoes accelerate soiling. Every 6–12 months is appropriate for households with young children.
Allergy and Asthma Sufferers
Carpets accumulate dust mite waste, pollen, pet dander and mould spores — all significant allergen triggers. Hot water extraction removes up to 98% of common household allergens from carpet fibres. If anyone in the household suffers from allergies or asthma, every 6 months is strongly recommended.
High Traffic Areas
Hallways, stairs and living room carpets in busy households accumulate soil much faster than bedroom carpets. Consider cleaning high-traffic areas every 6 months while extending bedroom carpets to 12–18 months.
Manufacturer Warranty Requirements
Many carpet manufacturers — including Brintons, Axminster and Ulster Carpets — require documented professional cleaning every 12–18 months as a condition of maintaining the warranty. Always check your carpet's documentation.
