Commercial Cleaning Services Across Cork
Cork is Ireland's second city and its largest county, stretching from the pharmaceutical hub of Ringaskiddy in the harbour to the tourist towns of Kinsale, Clonakilty, and Bantry along the coast, and inland through the market towns of Mallow, Fermoy, and Mitchelstown. With a population of over 580,000 across the city and county, Cork has a thriving commercial sector that demands professional cleaning services.
The Cork economy is distinctive. It is Ireland's pharmaceutical capital — Pfizer, Johnson & Johnson, Eli Lilly, MSD, and Novartis all have major manufacturing facilities in Ringaskiddy, Little Island, and Carrigtwohill. Cork also has a growing tech sector centred around the city's South Mall and Docklands, a world-class food and hospitality industry anchored by the English Market and dozens of award-winning hotels, and a major healthcare infrastructure including Cork University Hospital (CUH), the Mercy University Hospital, the South Infirmary, and Bon Secours Hospital Cork.
Optus Glean provides the complete range of cleaning and facilities services across Cork city and county. Whether you need daily office cleaning on the South Mall, specialist industrial cleaning at a pharma plant in Little Island, hotel housekeeping at a five-star resort in Kinsale, or HIQA-compliant healthcare cleaning at CUH, we have the teams, the training, and the insurance to deliver.

Sectors We Serve in Cork
Cork's economy is one of the most diversified in Ireland. From pharmaceutical manufacturing to five-star tourism, from university campuses to harbour-side construction, Optus Glean serves every sector with specialist cleaning teams.
Corporate & Pharmaceutical
Cork is home to Ireland's largest concentration of pharmaceutical and life sciences companies. Pfizer's facility at Ringaskiddy, Johnson & Johnson in Little Island, Eli Lilly in Kinsale, MSD in Brinny, and Novartis in Ringaskiddy collectively employ thousands. These facilities require specialist cleaning that goes beyond standard commercial cleaning — GMP-compliant protocols, cleanroom-adjacent procedures, and stringent hygiene standards. Beyond pharma, Cork city has a thriving office market on the South Mall, Lapps Quay, Albert Quay, and the emerging Docklands area, with companies like Apple, Qualcomm, and Trend Micro maintaining significant operations. Optus Glean provides daily office cleaning and specialist industrial cleaning to Cork's corporate and pharmaceutical sector.
Hotels & Tourism
Cork's hospitality sector ranges from luxury properties like Hayfield Manor, The River Lee Hotel, and Ballymaloe House to boutique hotels in Kinsale, Clonakilty, and Kenmare. The English Market attracts food tourists year-round. West Cork is a major destination on the Wild Atlantic Way. Cork city hotels demand the same guest-room standard as Dublin but often with smaller teams and tighter budgets. Optus Glean provides hotel housekeeping and commercial laundry services tailored to Cork's hospitality market, from city-centre business hotels to coastal resort properties.
Healthcare
Cork University Hospital (CUH) is the largest hospital in the South/South West Hospital Group and one of the busiest in the country. The Mercy University Hospital, South Infirmary Victoria University Hospital, Bon Secours Hospital Cork, and the Mater Private Cork all require HIQA-compliant cleaning with documented infection control protocols. Cork also has a dense network of GP surgeries, dental practices, and primary care centres across the city and county. Optus Glean provides healthcare cleaning with colour-coded systems, temperature-logged laundry processing, and audit-ready documentation for all Cork healthcare facilities.
Education
University College Cork (UCC) is one of Ireland's oldest and most prestigious universities. Munster Technological University (MTU, formerly CIT) has its main campus at Bishopstown. Cork also has dozens of secondary schools, primary schools, and language schools that require professional cleaning. Student accommodation at UCC's campus and purpose-built developments across the city need term-time and changeover cleaning. Optus Glean provides campus cleaning, student accommodation cleaning, and periodic deep cleaning to Cork's education sector.
Construction
Cork is experiencing significant construction activity, from the regeneration of the Docklands and the former Ford distribution site to residential developments in Ballincollig, Douglas, and Carrigaline. The Port of Cork's move to Ringaskiddy has opened up prime waterfront land for development. Every new building needs post-construction cleaning before handover. Optus Glean provides Safe Pass certified cleaning teams for builder's cleans and sparkle cleans on Cork construction sites.
