Frequently Asked Questions
The questions we get asked before every contract — answered upfront.
Do you work outside normal business hours?
Yes. We schedule around your operations, including nights, weekends and shutdowns, so cleaning never disrupts production or live environments.
Which areas do you cover?
Coverage widens by service — residential across Donegal & Derry, commercial throughout Ulster, industrial across all of Ireland, and data-centre work into the UK, Germany, the Netherlands and wider Europe.
Are you fully insured and accredited?
Yes — ISO 9001:2015 certified and ISO 14644 compliant, with full public and employers’ liability cover and site-specific RAMS available on request.
Do you offer one-off cleans or ongoing contracts?
Both. We handle one-off deep cleans and handovers as well as scheduled ongoing contracts tailored to your site and compliance needs.
How much do you charge?
Every site is different, so we price on scope. Request a free cleaning audit and we’ll return a clear, itemised quotation.
