Contract cleaning, specialist services, commercial laundry, and integrated facilities support for hotels, healthcare, corporate, and commercial clients.
Optus Glean operates across four dedicated divisions — contract cleaning, specialist cleaning, commercial laundry, and facilities support — delivering over twenty service lines to organisations across Ireland.
Every service is backed by documented method statements, risk assessments, and compliance frameworks. Every operative is Garda vetted and Safe Pass certified. Every site is managed with transparent reporting and quality audits.
We serve hotels, healthcare providers, corporate offices, retail, construction, property management, education, and transport clients from our base in Monaghan, with operational reach across all 26 counties.
Headquartered at Castle Leslie Estate in Glaslough, Co. Monaghan, we combine local knowledge with national reach. Our operational teams are permanently based in key regions across Ireland, ensuring consistent service standards whether you are in Dublin, Cork, Galway, or our home county of Monaghan.
Every client receives a dedicated account manager, monthly performance reports, and access to our 24/7 emergency response line. We hold €6.5 million public liability and €13 million employer’s liability insurance. All staff are Garda vetted and Safe Pass certified.

“Optus Glean took over our contract cleaning six months ago and the difference is remarkable. The documentation alone — method statements, risk assessments, monthly reports — puts them in a different league to our previous provider.”
— Facilities Manager, Hotel Group, Co. Monaghan
“We needed a cleaning company that understood HACCP compliance for our food processing facility. Optus Glean delivered a bespoke cleaning schedule, trained their team on our protocols, and passed our last audit with zero non-conformances.”
— Production Manager, Food Processing, Co. Monaghan
“What impressed us most was the transparency. Fixed pricing, no hidden charges, and a dedicated account manager who actually answers the phone. After years of unreliable cleaning contractors, it is genuinely refreshing.”

“We had a flood in our warehouse at 2am on a Saturday. Optus Glean had a team on site within three hours. They managed the entire cleanup, liaised with our insurance company, and had us operational again by Monday morning.”
