Most people assume window cleaning is window cleaning the same job, just at different scales. That assumption costs Dublin property owners and business managers money because the two services are genuinely different in how they are carried out, priced, and scheduled.
This guide breaks down exactly what sets commercial and residential window cleaning apart in Dublin, what each service actually involves, and what you should expect to pay, whether you’re a homeowner in Ranelagh or a facilities manager on the Quays.
The most obvious distinction is scale; a terraced house has far fewer windows than a five-storey office block. But the real differences run deeper than that, and they affect which equipment is used, what safety standards apply, how frequently the work is done, and what a realistic quote looks like.
Residential window cleaning is fundamentally a scheduled maintenance service for a home. The goal is clean glass, good visibility, and protecting window frames from long-term grime and salt deposit buildup, particularly relevant in coastal Dublin areas like Clontarf, Howth, and Dun Laoghaire, where sea air accelerates surface deterioration.
Commercial window cleaning, on the other hand, carries additional layers of complexity. Building height, public safety, business continuity, contract terms, and compliance with Ireland’s Health and Safety Authority work-at-height regulations all factor into how the job is planned and delivered.
Factor | Residential | Commercial |
Scale & Scope | Typically 10–30 panes per home; ground & first-floor access | Entire building facades, glass curtain walls, multi-storey access |
Equipment | Squeegee, bucket, extendable pole, ladder | Water-fed pole system (up to 70 ft), cherry picker, rope access |
Safety Requirements | Basic ladder safety; the homeowner can be present | HSA Work at Height Regulations, risk assessment, and insurance certification |
Scheduling | Flexible morning, weekend, one-off | Outside business hours preferred; contract-based frequency |
Cleaning Method | Squeegee + detergent or basic pole system | Purified deionised water dries streak-free, no chemical residue |
Frequency (Dublin) | Every 6–12 weeks for maintenance | Monthly or bi-monthly for retail/office; weekly for high-footfall |
Pricing Model | Per visit, based on window count | Ongoing contract or bespoke quote by building size |
For most Dublin homes, professional window cleaners use a combination of traditional squeegee technique for ground-floor access and extendable water-fed pole systems for first-floor windows. The water used in modern residential cleaning is purified through deionisation, removing the dissolved minerals in Dublin’s moderately hard tap water that would otherwise leave streaks and spots as the glass dries.
The result is a clean that requires no squeegee finish at height: the purified water evaporates without leaving any residue, meaning no towel-drying, no streaking, and less risk of damage to frames and seals.
For commercial buildings above two storeys, the equipment requirements change significantly. Water-fed carbon fibre poles can reach windows up to 70 feet from the ground eliminating the need for ladders on most low-to-mid-rise Dublin office buildings and retail properties. For higher structures, cherry pickers, rope access systems, and suspended platforms are used, each requiring certified operators and structured risk assessments.
Under Ireland’s Work at Height Regulations and HSA guidelines, commercial window cleaners operating above ground level must carry out formal risk assessments, use appropriate fall arrest equipment where required, and ensure operatives are competent for the specific access method used. Residential window cleaners working on domestic properties must meet the same standards when working at height — but commercial contracts typically require documented compliance as a condition of engagement. |
This is one of the gaps that competitors consistently leave unexplained, and it is actually one of the more useful things to understand before booking.
The frequency difference also affects pricing; commercial contracts almost always offer a lower per-visit rate in exchange for scheduled regularity, whereas residential one-off cleans are priced at a higher rate per session.
Pricing in Dublin varies by property type, access difficulty, window count, and whether both interior and exterior cleaning are included. The table below reflects current market rates across the Dublin area:
Property Type | Category | Dublin Cost | Notes |
Small house (1–2 bed) | Residential | €35 – €60 | External clean, up to 10 panes |
Large house (3–4 bed) | Residential | €60 – €100 | External, inc. frames & sills |
Apartment (interior + exterior) | Residential | €60 – €90 | Both sides, standard floors |
Small office/shopfront | Commercial | €80 – €150 | Ground floor, facade |
Mid-size commercial building | Commercial | €150 – €400 | Multi-floor, water-fed pole |
Large commercial/glass facade | Commercial | €400 – €4,500+ | Custom quote, specialist access |
Additional costs to factor in: hard-to-access windows (narrow side passages, windows over extensions, Velux or roof lights) typically add €10–€50 per visit. Interior window cleaning on both residential and commercial properties is usually charged separately from exterior-only service. Always confirm what is included — frames, sills, and screens are not always covered in base pricing. |
Dublin sits at the intersection of Atlantic weather systems and urban air pollution. Rain in Dublin does not clean windows; it washes street-level particulates, pollution deposits, and airborne salt onto glass and leaves them behind as water evaporates. Properties near the coast or in the city centre accumulate surface contamination faster than the Irish average.
Glass is also a porous material. Mineral deposits, traffic film, and biological growth (lichen, algae) that are left on glass surfaces long enough begin to bond with the surface rather than sitting on top of it. At that point, standard cleaning cannot fully restore the glass, and in the worst cases, replacement is the only option. Regularly scheduled cleaning, whether residential or commercial, prevents contamination from ever reaching that threshold.
The distinction is usually straightforward:
Some properties sit in between a shopfront with a flat above it, for example, or a large Georgian home converted into office space. In those cases, a provider who handles both services (and can quote correctly for each part of the building) avoids the complications of coordinating two separate contractors.

Generally, yes, but not always on a per-window basis. The higher cost reflects specialist equipment, safety compliance requirements, insurance coverage, and in many cases, the need to work outside business hours to avoid disrupting operations. For large buildings with high window counts, commercial contracts can actually deliver competitive per-pane rates precisely because of the volume involved.
A water-fed pole system uses a telescopic carbon fibre pole extendable to 70 feet or more to deliver purified deionised water through a brush head directly onto the glass. Because the water has had all minerals removed, it dries completely clear without leaving spots or streaks. The system allows cleaners to reach upper-floor windows safely from ground level, and is now the standard method for both residential upper-floor work and commercial low-to-mid-rise buildings in Dublin.
For most commercial properties, monthly cleaning is the practical baseline. High-footfall businesses, such as cafes, retail shops, medical practices, and gyms, typically benefit from fortnightly service to maintain consistent street presentation. Offices on quieter streets or in business parks can often manage bi-monthly cleaning without a visible impact on appearance.
Yes, in two ways. Properties in coastal areas (Clontarf, Malahide, Skerries, Dun Laoghaire) accumulate salt deposits faster and may need more frequent service. City centre properties often carry a small access premium due to parking constraints and traffic management requirements for service vehicles. Both factors are standard considerations in any professional quote.
Yes, and it is often the more convenient option. Providers who handle both residential and commercial work, such as Clean4U, can schedule both services and invoice them separately, eliminating the coordination overhead of managing two different contractors.
