Our commercial cleaning services explained
Trusted commercial cleaning for businesses across Hertfordshire and London
Kriss Professional Cleaning is a commercial cleaning company based in Watford, working with offices, property management firms, developers and construction companies across Hertfordshire and London. We specialise in flexible cleaning contracts and specialist post-construction cleaning — helping businesses maintain clean, safe and professional environments without disrupting day-to-day operations.
Our core contract work is office cleaning — daily, evening and weekend visits for small offices, multi-tenant buildings and serviced workspaces, with a single account manager and monthly quality-control audits. For block management firms and estate agents we run weekly communal area cleaning contracts covering staircases, lobbies, lifts, corridors and bin stores. For main contractors and developers we deliver post-construction and sparkle cleans with RAMS, PPE and CSCS-aware operatives, working to your handover checklist and snag list.
Specialist commercial cleaning when you need more
Alongside our core contracts we offer deep commercial cleaning for offices, kitchens and back-of-house; commercial carpet and hard-floor cleaning with industrial extraction machines and scrubber-dryers; and warehouse and industrial cleaning on overnight and weekend rotas. Every site gets full RAMS documentation, COSHH-compliant chemical handling and site inspection sign-off — see our health & safety policy for the paperwork main contractors and facilities managers expect from a serious commercial supplier.
Areas we cover
We're based in Watford and cover all of Hertfordshire and Greater London, including Watford, Bushey, Rickmansworth, St Albans, Hemel Hempstead, Luton, Borehamwood, Harrow, Edgware and Stanmore. If your site isn't listed, get in touch — we regularly mobilise further into central London for commercial contracts and post-construction projects. Transparent commercial cleaning pricing is published for every service.
Why commercial clients stay with us
Commercial cleaning is a trust business. You're handing over keys, alarm codes and access to your building, so the small details matter. Every contract is covered by £5 million public liability insurance, every operative is uniformed and ID-carrying, and every visit follows a documented checklist with monthly QC sign-off. We pay our team fairly, give them proper training, and keep the same operatives on your contract wherever possible — which is why our commercial clients renew year after year and why our Google reviews consistently sit at a five-star average.
