Deep Cleaning FAQs
What is included in a commercial deep clean?
A commercial deep clean covers all areas that routine daily cleaning does not reach: inside appliances, behind and underneath furniture, carpet extraction, hard floor machine scrubbing, descaling of washroom fixtures, cleaning of air vents and extractor fans, and thorough sanitisation of all touch points and surfaces. We tailor the scope to your premises.
How often should a commercial premises have a deep clean?
Most commercial premises benefit from a deep clean every 3–6 months alongside their regular daily cleaning schedule. Schools and medical practices typically require more frequent deep cleans — often termly or quarterly — to meet hygiene and compliance standards.
