Gwynedd
Commercial cleaning in Gwynedd, done properly
Gwynedd is the biggest county in Wales by area and one of the emptiest, and that shapes how cleaning works here. A contract in Bangor and one in Aberdaron are ninety minutes apart on roads that were not built for it. Covering the county properly means being organised around travel instead of pretending it does not exist. We route work geographically and hold enough crew to run more than one job at a time, which is why we can quote the far end of the Llŷn without a call-out charge.
The work splits three ways. Bangor carries the institutions — the university, the health board and the city centre — and its year runs on term dates. Caernarfon, Porthmadog and the coastal towns run on tourism and property, with holiday accommodation turning over weekly through the season. And across all of it sits construction, because the county housing programme and the private developments alongside it produce the builders and sparkle cleans that are our main work.
The buildings are genuinely old. Slate, stone and lime render outside the newer estates, much of it listed or in a conservation area, and most of it exposed to weather off the Irish Sea. That is why we soft wash as a matter of course. A lance strips lime render and forces water into a rubble wall, and the repair costs far more than the clean saved.
Cyngor Gwynedd is the council throughout, and Welsh is the working language across most of the county. Our crews are Welsh speakers.
Gwynedd does not stop at the county line, and neither do we.

Accredited and insured
SSIP through SMAS Worksafe, CITB approved, NJORD for carpet cleaning, and a registered waste carrier with Natural Resources Wales. £10m insured. Certificates and RAMS go out with every quote, not on request.
No. There is no call-out charge anywhere in the county, including the far end of the Llŷn. We route work geographically and run more than one job at a time, so the travel is built into how we schedule rather than added to your invoice.
All of them. We have pages for Bangor, Caernarfon, Porthmadog, Pwllheli and Criccieth because those are where most of our work sits, but we cover Bethesda, Llanberis, Blaenau Ffestiniog, Nefyn, Abersoch, Barmouth, Dolgellau and everywhere between. If you are in Gwynedd, we cover you.
Yes, and it is a large part of what we do in the county. Cyngor Gwynedd's housing programme, its schools and its public buildings all come with the same requirements: accreditation checked before anyone is let on site, and documentation issued with the quote. The county is also where most of our builders and sparkle cleans happen, because that is where the construction is.
Yes, and it changes the method. We soft wash rather than pressure wash on lime render, stone and old paintwork, because a lance strips the coating and drives water into the wall. We will tell you on the site visit what we would and would not put on a building.
Yes. Welsh is the working language across most of Gwynedd and most site conversations happen in it as a matter of course. It makes no difference to the clean, but it makes the job run more easily.
