Our Home County: Optus Glean Head Office in Glaslough

Monaghan is where Optus Glean is headquartered. Our registered office is at 26 Village Square, Castle Leslie Estate, Glaslough, Co. Monaghan, H18 XP59. Our operations management, senior team, and core administrative functions are all based here. This is not a brass-plate address — it is where we run the business from.

For Monaghan businesses, this means three concrete advantages that no competitor can match:

  • Fastest response times — Every town in Monaghan is within 30 minutes of our head office. Emergency callouts, site inspections, and quality audits happen same-day, often within hours.
  • Direct management access — Your contract is managed by the same people who run the company. Issues escalate directly to decision-makers, not through layers of regional management.
  • Lowest mobilisation costs — No travel surcharges, no fuel premiums, no minimum distance fees. Monaghan clients get the most competitive contract pricing in our portfolio.

Commercial Cleaning Across County Monaghan

County Monaghan has a population of approximately 65,000 spread across three principal towns — Monaghan town, Carrickmacross, and Clones — and a network of smaller towns including Castleblayney, Ballybay, Emyvale, and Glaslough. Despite its relatively small population, Monaghan punches well above its weight economically, particularly in food processing, manufacturing, and cross-border commerce.

The county sits on the Northern Ireland border, with Armagh, Tyrone, and Fermanagh to the north. This border position means many Monaghan businesses operate cross-border supply chains, logistics, and distribution. As a locally headquartered company, we understand this dynamic intimately.

Food Processing: Monaghan’s Economic Engine

Monaghan has one of the most concentrated food processing sectors in Ireland relative to its population. The county’s major food employers include:

  • Monaghan Mushrooms — Europe’s largest mushroom producer, headquartered in Monaghan with operations across Ireland and the UK
  • Silver Hill Foods — Duck processing facility in Emyvale, supplying supermarkets and restaurants across Europe
  • Grove Turkeys — One of Ireland’s largest turkey producers, based in Smithborough
  • Monaghan Poultry — Poultry processing in Carrickmacross
  • Combilift — While primarily a forklift manufacturer (1,000+ employees), Combilift’s Monaghan facility has significant industrial cleaning needs

We provide industrial cleaning for food processing plants, manufacturing facilities, and warehouses across the county. Our teams are trained in HACCP-compliant cleaning protocols, food-grade sanitisation, cold store maintenance, and production floor cleaning. We operate across day, evening, and night shifts to match client production schedules.

Castle Leslie and Tourism

Our registered office sits within the Castle Leslie Estate, one of Ireland’s most distinguished castle hotels. Castle Leslie gained international fame as the venue for Paul McCartney and Heather Mills’ wedding in 2002. The estate has 1,000 acres, equestrian facilities, a spa, and a range of accommodation from the castle itself to village cottages. Glaslough village has been named Ireland’s tidiest village multiple times.

Beyond Castle Leslie, Monaghan’s hospitality sector includes the Four Seasons Hotel & Leisure Club in Monaghan town, the Glencarn Hotel in Castleblayney, the Nuremore Hotel & Country Club in Carrickmacross, and the Creighton Hotel in Clones. We provide hotel and hospitality cleaning with integrated laundry services for properties across the county.

Healthcare Cleaning

Monaghan’s healthcare needs are served primarily by Cavan General Hospital (the acute hospital for the Cavan-Monaghan region) and by a network of GP surgeries, dental practices, and primary care centres across Monaghan town, Carrickmacross, and Clones. St Davnet’s complex in Monaghan town provides mental health and community healthcare services.

We provide healthcare cleaning with full HSE compliance, colour-coded equipment, hospital-grade disinfectants, and HIQA audit-ready documentation. Our proximity means healthcare clients get same-day response for urgent cleaning requirements.

Carrickmacross: Lace Town

Carrickmacross, famous for its lace-making tradition, is Monaghan’s second-largest town. The Nuremore Hotel & Country Club is a premier golf and conference destination. The town has a busy retail centre, the Carrickmacross Retail Park, and several manufacturing and food processing operations. The Carrickmacross Lace Gallery is a cultural attraction drawing visitors from across Ireland.

Clones: Border Hub

Clones sits right on the Northern Ireland border and is the traditional home of GAA Ulster football. The town has a historic diamond (town square), St Tiernach’s Park (venue for Ulster Championship matches), and a growing number of small businesses serving both cross-border shoppers and local residents. The Canal Stores and heritage round tower add to the town’s appeal.

Patrick Kavanagh Country

Monaghan is the home county of Patrick Kavanagh, one of Ireland’s greatest poets. The Patrick Kavanagh Centre in Inniskeen, the Kavanagh Trail, and the annual Patrick Kavanagh Weekend draw literary tourists. Inniskeen also hosts the annual Inniskeen International Festival. We serve tourism and cultural venues across the county.

Why Choose a Monaghan-Based Cleaning Company

When you hire a Dublin-based cleaning company to service your Monaghan premises, you pay for their travel time, you wait longer for emergency response, and you deal with regional managers who may visit your site once a quarter.

  • Same-day site surveys — We can inspect your premises today and have a detailed quotation in your inbox by tomorrow morning.
  • Local recruitment — Our Monaghan cleaning teams live in the county. They know the roads, the towns, and the businesses. Lower staff turnover means consistent quality.
  • Direct escalation — If there is ever an issue with your service, you can walk into our head office at Castle Leslie Estate and speak to the people who run the company.
  • Community investment — We hire locally, we buy supplies locally, and we contribute to Monaghan’s economy. Your cleaning contract stays in the county.
  • Cross-border expertise — Monaghan sits on the Northern Ireland border. Many of our clients operate cross-border. We understand the logistics, the regulations, and the commercial realities of border-region business.
