Office Deep Clean in Dublin: What's Covered, How Long It Takes and How Much It Costs in 2026

By the team at Premier Contract Cleaning. Dublin's trusted commercial cleaning company, keeping offices and corporate spaces healthy and presentable across the city for almost a decade.

Some offices look fine at a glance, but they do not feel clean.

The carpet has greyed in the walkways, the vents are furred with dust, the kitchen has that faint stale smell, and a bug has just gone round half the team. The weekly clean is keeping the surface tidy, but the build-up underneath has crept up quietly.

We get this call a lot, usually right then, or just before a big client visit.

After almost a decade deep-cleaning Dublin offices, here is exactly what an office deep clean covers, how it differs from your regular clean, how long it takes, how often you need one, and what it costs in Dublin in 2026, with honest numbers.

What Is the Difference Between Office Cleaning and Office Deep Cleaning?

Regular office cleaning is routine maintenance, done daily or weekly, that keeps the visible surfaces tidy: desks wiped, floors vacuumed, bins emptied, kitchen and washrooms kept presentable. An office deep clean is an intensive, periodic, top-to-bottom clean that reaches everything routine cleaning does not: behind and under furniture, air vents, skirting boards, carpets deep down, inside appliances, and every high-touch point. In short, regular cleaning maintains, a deep clean restores.

The simplest way we explain it to clients is this. Your weekly clean keeps the office looking good. A deep clean makes it genuinely clean again.

Regular office cleaning (maintenance)

This is the day-to-day work that keeps things presentable. Surfaces wiped, floors vacuumed, bins emptied, the kitchen and washrooms kept fresh.

It is essential, and it is what most offices need most of the time. But by design, it works fast and stays on the surface.

Office deep cleaning (restoration)

A deep clean is a different job entirely. It is slower, more detailed, and it goes after the dirt a quick clean never touches.

That means the grime behind the furniture, the dust in the vents, the build-up on the skirting, and the soil deep in the carpet fibre. It is the periodic reset, not the weekly tidy.

Here is the difference at a glance:

What Areas Are Covered in an Office Deep Clean?

An office deep clean covers everything a regular clean skips. That means workstations including under and behind them, every high-touch point, floors taken back with carpet extraction or a hard-floor scrub, skirting boards, high dusting of ledges, vents and light fittings, the kitchen inside and out, washrooms deep-scrubbed and descaled, interior windows, sills and blinds, upholstery, glass partitions, reception, and waste areas. The aim is to reach the dirt that builds up out of sight.

Think of it as cleaning the parts of the office nobody usually looks at, because that is exactly where the problems hide.

Desks, high-touch points, and floors

We start where people spend their day. Workstations get cleaned thoroughly, including under and behind them, not just the top of the desk.

High-touch points get proper attention too: keyboards, phones, door handles, and light switches. Then the floors are taken back, with carpet extraction or a hard-floor scrub, depending on what you have.

Kitchens and washrooms (the deep-scrub zones)

These two rooms always need the most work. In the kitchen, that means appliances inside and out, cupboards, the sink, and descaling.

In the washrooms, it is a full deep scrub: descaling, grout, and proper sanitising of every surface. These are the areas staff notice first when they are neglected.

The detail work

The rest is the detailing that makes a deep clean a deep clean:

• High dusting of ledges, tops of cabinets, and light fittings
• Air vents and grilles
• Skirting boards
• Interior glass, windows, sills, and blinds
• Upholstery and glass partitions
• Reception and waste areas

What we find in an office: We once deep-cleaned a Dublin office where the weekly clean was genuinely good. But nobody had touched the vents or skirting in years. The dust we pulled out of the vents alone changed how the whole place smelled.

How Long Does an Office Deep Clean Take?

An office deep clean takes anywhere from a few hours to several days, depending on the size of the office, the layout and access, and how much build-up there is. A small office might be done in an evening, a medium office in a full day, and a large or multi-floor office over several days or with a bigger crew. We usually work after hours or at weekends, so the office is ready and undisturbed when staff arrive.

There is no single answer, because no two offices are the same. But the size and condition give us a clear estimate at the survey stage.

What affects the time

A few things move the clock:

• The floor area and the number of rooms and workstations
• The condition, and how much build-up there is
• Access, and how much furniture has to be worked around
• The depth of work you need beyond a standard deep clean

Why we work after hours

Here is the part that reassures most managers. We do the work when the office is empty.

Evenings, overnight, or at the weekend. You leave a tired office on Friday and walk into a reset one on Monday, with no downtime and no disruption to your team.

As a rough guide:

How Often Should an Office Have a Deep Clean in Ireland?

Most Irish offices benefit from a deep clean every three to six months, on top of their regular cleaning. Busier or larger offices, those with 10 to 50 staff or high footfall, often move to every two to three months. Bring a deep clean forward after an illness has gone round, before a big client visit or audit, at the change of seasons, or whenever the office starts to feel grimy despite the regular clean.

The right schedule depends on your office, but most settle into a rhythm once they see the difference a deep clean makes.

By office size and traffic

Smaller, quieter offices usually do well on a deep clean every three to six months. Busier offices, or larger teams of 10 to 50 staff, tend to need one every two to three months.

The more feet through the door, the faster the build-up returns. High-footfall receptions and shared kitchens are always the first to show it.

When to bring a deep clean forward

Some moments are worth an extra clean, whatever the schedule says:

• After a cold or flu has gone round the team
• Before a client visit, audit, or inspection
• At the change of seasons, especially after winter
• When the office feels grimy despite a good weekly clean

Here is a simple guide:

How Much Does an Office Deep Clean Cost in Dublin?

In Dublin in 2026, office deep cleaning typically runs around €30 to €50 per hour per cleaner, because it is far more labour-intensive than a regular clean. A one-off deep clean for a smaller office often starts from a few hundred euro, with many general commercial deep cleans starting around €500 and rising with size and condition. The exact figure depends on your office, so we always quote from a free site survey.

We will be honest about price here, because vague quotes help nobody. These are 2026 guide figures, and the real number comes from seeing your space.

What drives the price

Five things shape the cost:

• The office size, by square metre or number of rooms
• The condition, and how much build-up there is
• The scope, or how much you want covered
• Access, and how much furniture has to be moved
• Whether it is a one-off or a recurring deep clean

Pricing models and Dublin rates

Deep cleans are quoted a few ways: per hour per cleaner, per square metre, or as a fixed per-job price. We usually give a fixed quote, so you know the number upfront.

One local note worth knowing. Dublin runs roughly 15 to 25 percent above regional Ireland, because labour costs more in the city. That is normal, and it is why a clear, survey-based quote matters.

Here is a rough 2026 guide:

A deep clean is an investment in a healthier, better-looking office, and it makes your regular clean more effective afterwards. For the broader service across all premises, see our commercial deep cleaning guide, and for everyday pricing, our office cleaning cost guide.

Regular cleaning maintains, a deep clean restores.

A smaller office often starts from a few hundred euro, with many commercial deep cleans from around €500, rising with size and condition. We quote a fixed price from a free survey.

Is an office deep clean worth it? Yes, for most offices. It removes the build-up regular cleaning cannot reach, improves air and hygiene, helps carpets and surfaces last longer, and makes the everyday clean more effective afterwards. It is an investment in a healthier, better-looking workspace.

Can you deep clean our office after hours or at the weekend? Yes. We schedule overnight, in the evenings, or at weekends, so the work never disrupts your team. You leave the office in the evening and arrive to a fully reset, fresh space in the morning.
