What our commercial deep cleaning covers
Every deep clean is planned around your building, your access and the level of soiling, so the right method and equipment are matched to each area.
- ✧Offices & Workspaces. Full deep cleans of desks, workstations, meeting rooms and open-plan areas, including edges, skirtings and detail that routine cleaning cannot reach.
- ✧Washrooms & Welfare Areas. Intensive cleaning and sanitising of toilets, basins, tiling and grout, restoring hygiene and presentation in the areas that show soiling first.
- ✧Kitchens & Breakout Areas. Deep cleaning of staff kitchens, canteens and breakout spaces, including appliances, surfaces and dining areas, supporting a hygienic environment for staff.
- ✧High-Level & Hard-to-Reach Cleaning. Cleaning of high-level surfaces, ledges, vents, light fittings and other areas that accumulate dust and are missed by day-to-day cleaning.
- ✧Floors & Communal Areas. Machine cleaning of hard floors and extraction of carpets in receptions, corridors and communal spaces, refreshing the first impression of your building.
- ✧Touch-Point Sanitising. Targeted sanitising of door handles, switches, rails and shared surfaces, reducing the spread of illness across busy commercial premises.
Every clean is scheduled, tracked and quality-checked through our CleanManager platform, with photographic evidence and completion reporting available on request.
DBS-checked operatives. COSHH compliant. Method statements and RAMS provided where required.
How We Work
Every building is different, so we plan each commercial deep clean around your access, the level of soiling and the safest, most effective method for each area.
01. Enquiry and Assessment
We start with a conversation about the premises, the areas involved and the standard you need to reach. For larger sites we carry out a site visit to assess the surfaces, access and level of soiling before quoting.
02. Planning and Preparation
We confirm the scope, method and equipment, agree timings around your operation and produce site-specific RAMS where required, so everything is in place before we arrive on site.
03. Delivery
Our work is led on site by an experienced operative who manages method and equipment throughout. We work area by area with professional machinery and products, out-of-hours where needed to avoid disruption.
04. Final Check and Sign-Off
Before we leave, we walk every area covered and confirm the result meets the agreed standard. Recurring deep cleans are logged so results stay consistent visit after visit.
