Professional Commercial Window Cleaning in Ireland
Clean windows are one of the most immediate visual signals of a well-maintained building. Whether it is a shopfront on Grafton Street, a corporate office block in Sandyford, a hotel overlooking Galway Bay, or a hospital in Cork, the appearance of your windows communicates professionalism, attention to detail, and pride in your premises. Dirty, streaked, or neglected windows communicate the opposite.
Optus Glean provides commercial window cleaning services to businesses and organisations of every size across all 26 counties of Ireland. We clean windows at any height using the safest and most appropriate access method for each building: water-fed pole for buildings up to 6 storeys, rope access for high-rise buildings, MEWP (Mobile Elevating Work Platforms) and cherry pickers for difficult access points, and traditional methods for internal windows and ground-floor retail.
Every window cleaning operative is Garda vetted, trained in work-at-height safety, and covered by our €6.5 million public liability and €13 million employer's liability insurance. All work is carried out under documented method statements and site-specific risk assessments compliant with the Safety, Health and Welfare at Work Act 2005.
Access Methods: The Right Tool for Every Building
The access method determines the cost, speed, safety profile, and quality of the window clean. Optus Glean assesses every building during a free site survey and recommends the safest, most cost-effective method.
Water-Fed Pole Systems
Water-fed pole cleaning is the most common method for commercial buildings up to 5 or 6 storeys (approximately 20 metres). Telescopic carbon fibre poles deliver purified water to a rotating brush head that scrubs the glass and frames. The water is purified through a multi-stage deionisation and reverse osmosis system that removes all dissolved minerals, so it dries completely clear with no spots or streaks.
Water-fed pole systems offer significant advantages over traditional ladder and squeegee methods:
- No ladders required, eliminating the most common cause of window cleaning injuries
- Operatives work from ground level, complying with work-at-height regulations
- Frames, sills, and rubber seals are cleaned simultaneously with the glass
- Pure water attracts less dirt after cleaning, so windows stay cleaner for longer
- Faster than traditional methods for multi-storey buildings
- No chemicals used — pure water only
Our water-fed pole systems produce up to 500 litres of purified water per day, enough to clean the windows of a large commercial building in a single visit.
Rope Access
For buildings above 6 storeys or where building geometry prevents pole access, rope access is the preferred method. Rope access technicians descend the building face on industrial ropes, using traditional squeegee and applicator techniques to clean each window by hand.
All Optus Glean rope access operatives hold IRATA (Industrial Rope Access Trade Association) or equivalent certifications. Teams always work in pairs: one technician cleans while the other manages safety lines from the roof anchor point. Rope access is:
- More cost-effective than scaffolding or building management units (BMUs)
- Faster to set up and demobilise than MEWP or scaffolding
- Suitable for buildings of any height, including high-rise commercial and residential towers
- Effective on complex building facades with recesses, overhangs, and curved surfaces
MEWP and Cherry Picker
Mobile Elevating Work Platforms (MEWPs) include cherry pickers, scissor lifts, and boom lifts. These are used where rope access is not practical — for example, on buildings without suitable roof anchor points, or where the ground surface allows vehicle access right up to the building face.
MEWP operation requires IPAF (International Powered Access Federation) trained operators. Optus Glean arranges MEWP hire and operation as part of the window cleaning contract, so you receive a single invoice for the complete service. Cherry pickers can reach up to 40 metres or more depending on the machine specification.
Traditional Methods
For internal window cleaning and ground-floor retail frontages, traditional squeegee and applicator techniques remain the most appropriate method. Internal window cleaning is typically included in office cleaning contracts or can be booked as a standalone service. Shopfront window cleaning using traditional methods is fast, inexpensive, and provides an impeccable hand finish.

Combined Service: Windows, Gutters, and Fascia
Most commercial buildings need more than just window cleaning. Gutters fill with leaves, moss, and debris. Fascia boards and soffits accumulate dirt and algae. Cladding panels lose their appearance over time. Optus Glean offers a combined exterior cleaning service that covers all of these elements in a single visit.
Gutter Cleaning
Blocked gutters cause water overflow, damp penetration, and structural damage to buildings. Our gutter cleaning service uses a combination of gutter vacuum systems (operating from ground level) and manual clearance from height where necessary. We remove all debris, flush downpipes to ensure they are clear, and report any damage or repairs needed. Gutter cleaning is typically priced from €3 to €6 per linear metre.
Fascia, Soffit, and Cladding Cleaning
UPVC fascia boards, soffits, and cladding panels are cleaned using soft-wash techniques with the water-fed pole system. This removes algae, moss, traffic film, and atmospheric staining without damaging the surface. For painted or coated surfaces, we use appropriate cleaning solutions that remove dirt without affecting the finish. Fascia cleaning is typically combined with window cleaning visits for maximum efficiency.

Frequently Asked Questions About Commercial Window Cleaning
How much does commercial window cleaning cost in Ireland?
Commercial window cleaning in Ireland costs between €2 and €8 per window pane depending on the height, access method, and window size. Ground-floor shopfronts start from €2 to €4 per pane. Water-fed pole cleaning costs €3 to €5 per pane. High-rise rope access or MEWP work starts from €6 to €8 per pane. Monthly contracts for commercial buildings range from €150 to €600+ per visit depending on building size. Optus Glean provides free site surveys and fixed-price quotations.
How often should commercial windows be cleaned?
Most commercial buildings benefit from monthly window cleaning. Retail premises and customer-facing buildings should be cleaned fortnightly or monthly. Office buildings typically schedule monthly or bi-monthly cleans. Industrial premises may only need quarterly cleaning. The ideal frequency depends on location, proximity to roads, pollution levels, and your standards. Optus Glean offers flexible scheduling from weekly to quarterly programmes.
What is water-fed pole window cleaning?
Water-fed pole cleaning uses telescopic carbon fibre poles reaching up to 20 metres (5–6 storeys). Purified water is pumped through the pole to a brush head that scrubs the glass and frame. The water is purified through deionisation and reverse osmosis, so it dries without spots or streaks. It is safer than ladder work, faster for multi-storey buildings, and produces a superior finish because frames and sills are cleaned simultaneously.
What is rope access window cleaning?
Rope access involves IRATA-certified technicians descending the building face on industrial ropes to clean windows by hand. It is used on buildings above 6 storeys or where building geometry prevents pole access. Teams always work in pairs for safety. Rope access is often more cost-effective than scaffolding or cherry pickers and can be set up and demobilised quickly with minimal disruption to the building's occupants.
How high can water-fed poles reach?
Commercial water-fed poles can reach up to 20 metres, approximately 5 to 6 storeys. Specialist poles extend to 25 metres in some cases. Effective reach depends on the pole material, wind conditions, and building access. For buildings above 6 storeys, rope access or MEWP methods are required. Optus Glean assesses the appropriate method for each building during a free site survey.
Is window cleaning at height regulated in Ireland?
Yes. Window cleaning at height is regulated under the Safety, Health and Welfare at Work Act 2005 and the General Application Regulations 2007, Part 4 (Work at Height). The regulations require risk assessment, use of the safest practicable access method, and fall prevention measures. The Health and Safety Authority (HSA) enforces these regulations. Optus Glean maintains full compliance documentation including method statements and site-specific risk assessments.
What safety regulations apply to window cleaning in Ireland?
Key regulations include the Safety, Health and Welfare at Work Act 2005, the General Application Regulations 2007 (Part 4), and HSA guidance on window cleaning and work at height. Requirements include conducting risk assessments, using the safest practicable access method, ensuring operative training and competence, maintaining fall protection equipment, and documenting all safety procedures. IRATA certification is required for rope access, and IPAF training for MEWP operation.
