FAQs
Common questions
Including what it costs, answered with a real range and the reasons it moves.
Gwynedd, Anglesey and the North Wales coast. Bangor, Caernarfon, Porthmadog, Pwllheli, Criccieth, Menai Bridge, Llangefni, Holyhead, Llandudno, Colwyn Bay and Rhyl, plus the villages between them. No call-out charge anywhere we go.
We carry £10m public liability cover and hold SSIP accreditation through SMAS Worksafe, along with CITB certification and NJORD accreditation for carpet cleaning. Certificates go out with every quote. A principal contractor or a public-sector client needs them on file before we start.
Yes, job-specific risk assessments and method statements, issued with the quote. They are written for your site. If your principal contractor wants a particular format, we will produce it. Generic RAMS — risk assessments and method statements — are the ones that get rejected.
Employed directly by us and DBS checked. It costs more than subcontracting. It is also why holiday and sickness cover actually happens. Most of the problems people have had with cleaning contractors trace back to subcontracted labour.
From a site visit, not from a drawing or a phone call. Someone comes and looks at the building — the area, the state of it, access, welfare, power and water — and you get a written fixed price against a scope you can check. Estimates given without a visit are the reason final invoices do not match quotes.
Two to three weeks is comfortable for a builders clean or the start of a contract, and it gives us time to do the visit and get the paperwork to your principal contractor. We do take shorter notice, because programmes move and that is normal. Crew size is the constraint. Early notice means we can put more people on it.
