Commercial Deep Cleaning in Dublin: What's Included, How Long It Takes, and What It Costs
By the team at Premier Contract Cleaning. Dublin's trusted commercial cleaning company, deep cleaning offices, gyms, and showrooms across the city for almost a decade.
A deep clean should be a genuine reset, not a normal clean with a bigger price tag.
We say that because we have seen the other version. A business books a "deep clean," pays a premium, and gets something that looks suspiciously like the weekly service. No wonder people are wary.
Others just stare at the quote, unsure why it costs so much more than a regular clean.
After almost a decade of commercial cleaning in Dublin, let us clear it up. Here is exactly what a proper commercial deep clean includes, what it does not, how long it takes, and what it should cost, so you know precisely what you are paying for.
How Much Does a Commercial Deep Clean Cost in Dublin?
A commercial deep clean in Dublin typically starts in the low hundreds of euro for a small office and rises to €500 or more for larger or heavily soiled premises. The price is based mainly on the floor area, the condition of the space, and the scope of work. Because deep cleans vary so much, the only truly accurate figure comes from a site survey.
A regular clean is predictable. A deep clean is not, because the starting condition changes everything.
How commercial cleaning is priced per square metre
In Ireland, we price by the square metre, not the square foot (one square metre is about 10.76 square feet). Dublin runs roughly €2.00 to €4.50 per m² for regular cleaning, and deep cleans are priced higher because of the extra time and detail involved.
Dublin also sits about 15 to 25 percent above the rest of the country, mainly due to higher labour and operating costs.
What's a reasonable price, and what drives it
A fair deep-clean price reflects the real work. The main factors are:
- The size of the space in m²
- Its condition and how much build-up there is
- The scope (which areas and how detailed)
- Access and how easy the space is to work in
- Frequency (regular cleaning keeps future deep cleans cheaper)
How is a commercial deep clean estimated?
We never price a deep clean over the phone. We do a site survey, measure the area, assess the condition and scope, then factor in labour at the legal ERO rate, materials, time, and a fair margin.
If you run a cleaning business, that is the same formula you would use. For a buyer, it is simply what sits behind an honest quote.
| Space | Typical guide | Note |
| Small office | Low hundreds of euro | Exact price from a site survey |
| Medium office | A few hundred euro+ | Depends on condition and scope |
| Large or multi-floor | €500 and up | Often phased over a day or more |
Why Is Deep Cleaning So Expensive?
A deep clean costs more because it is far more labour-intensive than a regular clean. It takes more hours, often a full team, specialist equipment and products, and detailed work on areas a routine clean never touches. You are paying for time, expertise, and a genuinely thorough result, not a quick once-over.
It only looks expensive next to a regular clean. Next to the cost of replacing worn carpets or losing clients to a shabby space, it is good value.
What you're actually paying for
The price covers real, specific work:
- Far more hours than a standard clean
- A trained team rather than one cleaner
- Specialist kit like carpet machines and descalers
- Reaching hidden, built-up grime that takes time
- The real costs behind a compliant service: ERO wages and insurance
Is a Commercial Deep Clean Worth It?
For most businesses, yes. A deep clean improves air quality and hygiene, extends the life of carpets, furniture, and surfaces, supports fewer sick days, and protects the professional image that staff and clients judge you on. It also resets a space so your regular cleaning can keep it that way more cheaply.
We often see the value land hardest with first impressions. A spotless reception or showroom changes how people feel before a word is said.
The return on a deep clean
A deep clean pays back in a few ways:
- Healthier air and fewer germs, which can mean fewer sick days
- Longer life for carpets, upholstery, and floors
- A professional image for clients and staff
- Support for hygiene and compliance standards
- Lower ongoing costs when you pair it with a regular cleaning plan
That last point matters. A deep clean plus a maintenance contract is usually cheaper over a year than repeated emergency deep cleans.
What Does a Commercial Deep Clean Include?
A commercial deep clean covers everything a regular clean does, plus the neglected and hard-to-reach areas. That means detailed kitchens including appliances, fully sanitised and descaled washrooms, carpet and floor deep cleaning, high and hidden dusting, vents and light fittings, skirting boards, behind and under furniture, and thorough disinfection of high-touch points.
In short, a regular clean keeps a space presentable. A deep clean gets it genuinely clean, top to bottom and front to back.
A deep clean, area by area
Here is what a proper commercial deep clean reaches:
- Kitchens and breakrooms: appliances inside and out, inside cupboards, descaling
- Washrooms: descaling, soap scum, full sanitisation
- Floors: carpet shampoo or steam clean, hard-floor deep care
- Surfaces: high and hidden dusting, not just desktops
- Windows and glass: internal glass, frames, sills
- Vents and light fittings: where dust quietly builds up
- High-touch points: thorough disinfection
What areas are often missed during deep cleaning?
Even some "deep" cleans skip the same spots. The usual misses are skirting boards, vents, light fittings, the areas behind and under appliances and furniture, window tracks, and the tops of partitions and cabinets.
A good checklist catches every one of them. That is exactly why we work to a site-specific list rather than from memory.
What a Deep Clean Does NOT Include
A deep clean is a cleaning service, not a repair or renovation. So it usually does not include fixing or maintenance work, decluttering or organising belongings, exterior cleaning, specialist restoration like mould remediation or pest control, or moving heavy furniture and IT equipment. Anything outside the agreed scope should be quoted separately.
We are upfront about this for a reason. Knowing the limits prevents the awkward "I thought that was included" conversation later.
Where deep cleaning ends and other services begin
These usually sit outside a standard deep clean:
- Repairs and maintenance
- Decluttering or organising your belongings
- Exterior cleaning
- Specialist restoration (mould remediation, pest control)
- Moving heavy furniture or IT equipment
If you need any of these, we will tell you during the survey and point you in the right direction. A clear scope keeps everyone happy.
How Long Does a Commercial Deep Clean Take?
A small office deep clean usually takes about 2 to 4 hours, while a larger commercial space often runs 4 to 8 hours. Multi-floor buildings can take a full day or several days. The time depends on the size of the premises, the level of soiling, and the scope of work.
We can also work after hours or at the weekend, so the deep clean does not disrupt your business.
What affects the timing
A few things set the clock:
- The size of the space and number of floors
- How dirty it is to start with
- The scope and how detailed it needs to be
- The size of the team and how accessible the space is
For anything large, we often plan the work in phases so your operation keeps running.
The 6 Main Stages of Effective Deep Cleaning
The six main stages of effective deep cleaning are pre-clean, main clean, rinse, disinfection, final rinse, and drying. Following them in order is what separates a true deep clean from a surface wipe-down. Each stage prepares the surface for the next, so dirt is removed first and germs are killed properly afterwards.
This sequence matters most in kitchens and washrooms, where hygiene is critical.
Here are the six stages in order:
- Pre-clean to remove loose dirt and debris
- Main clean to loosen and lift dirt and grease
- Rinse to remove the loosened soil and detergent
- Disinfection to kill remaining germs
- Final rinse where the disinfectant needs it
- Drying to leave the surface clean and ready
Skip a stage and you either spread dirt around or stop the disinfectant from working. Done in order, it gets a surface genuinely hygienic, not just shiny.
