A showroom manager on a main road on Dublin's southside rang us at 7.40am one morning. He had just opened up to find silver tag lines sprayed across his fascia and a crack running through one glass panel. His first instinct, he admitted later, was to send a staff member out with a bottle of […]
What to Do When a Power Outage Interrupts a Scheduled Clean
One stormy evening, a two-person crew of ours was an hour into an office clean in a Sandyford block when everything died at once. The lights, the lifts, the alarm panel, the scrubber drier mid-corridor, all gone in a blink.
No panic, no phone calls home. What they did in the next ten minutes is more or less this entire article.
We have been cleaning Dublin offices in the early morning and evening windows for nearly a decade, and outages find you eventually, from storm faults to planned shutdowns nobody passed on to the cleaning contractor. Here is the drill, for the crew and for the building.
The Short Answer: Safety First, Then Salvage the Visit
Stop machine work immediately and make the area safe, especially wet floors in darkness. Check whether the outage is local or wider using the ESB PowerCheck map, and treat all sockets and equipment as live. Continue battery and manual tasks where lighting allows, then reschedule powered work with your cleaning contractor.
That is the whole event in four sentences. The value is in the detail, because a power cut during a clean creates a handful of hazards that catch out crews and building managers who have never met one before.
First Five Minutes: Make the Building Safe
The first job is not finding out why the power went. It is making sure nobody gets hurt while it is out.
Torches and phone lights come on first. Then wet floors, because a freshly mopped corridor in a dark building is the single most dangerous thing in this whole scenario. Dry it, cone it or block it before anyone crosses it, including the crew themselves.
Equipment gets parked out of walkways and unplugged, every machine. Unplugging matters more than people think: when power returns, you do not want a buffer or an urn restarting unattended in an empty building.
Then two checks. Are the lifts empty, or is someone inside? Entrapments are handled by building management or the emergency services, never by improvising. And is the emergency lighting doing its job? If corridors and stairwells are properly lit, more of the visit can be saved.

Find Out What You Are Dealing With
Local trip or area outage?
Not every blackout is an outage. Sometimes one circuit has tripped, and the fix is a fuse board away.
If someone competent is on site, a glance at the board and the RCDs settles it quickly. A single tripped circuit is a building matter for building management or an electrician. The whole block dark, and the street dark with it, is a different event entirely.
Check ESB PowerCheck and report faults
For area outages, the answer is on your phone. The ESB PowerCheck map shows live outages and estimated restoration times, which is exactly the information that decides whether the crew waits, works or goes home.
Faults are reported to ESB Networks on 1800 372 999. And one rule from ESB Networks stands over everything else that happens in the building: regard the supply as live at all times during an outage. Power can return without warning, so nothing gets poked, tested or trusted.
Storm nights are different
During a Met Eireann orange or red warning, restoration estimates stretch and the roads themselves may not be worth being on. On the worst nights, standing a crew down entirely is the only responsible call, and a contractor willing to say so out loud is one you can trust with your building.
What Cleaning Can Continue Without Power (and What Cannot)
Can continue
More survives an outage than most people expect, provided the light holds. In daylight or well-lit areas, a crew can keep going with:
- Dusting and wiping, high surfaces to low
- Sanitising touchpoints: handles, switches, rails, phones
- Spot cleaning, litter picking and bin rounds
- Sweeping, and mopping in zones that are properly lit
- Battery vacuums and battery scrubber driers, where the contractor runs them
- Restocking washroom consumables
A well-equipped crew with battery kit can quietly land most of a routine visit this way.
Must stop
The other list is not negotiable. Corded vacuums, buffers and scrubber driers are done for the night. Anything needing hot water stops where the building's supply is electric. And windowless rooms, stairwells and basements without adequate emergency lighting become no-go zones, no matter how much work is left in them.
The half-cleaned carpet problem
One detail from hard experience. If the power dies midway through hot water extraction, the wetted section of carpet cannot simply be abandoned until next week. It either gets finished with battery kit or protected and rescheduled fast, because a half-extracted carpet dries with a visible tide mark that then needs a second full clean. Small thing, but it is the difference between a crew that has met this before and one that has not.
The Client Side: What the Building Occupier Should Do
If it is your building, a short parallel checklist runs alongside the crew's.
Notify building management first, and in a multi-tenant block let neighbouring tenants know, since one call to ESB Networks covers everyone and twenty duplicate reports help nobody. Then think about your access control and alarm systems, because on battery backup some fail open and some fail locked, and either one matters for a crew inside and for security overnight.
In the office kitchen, keep fridge and freezer doors shut and note the time the power went. For ordinary staff milk and lunches this is a judgement call. For catering stock, food safety guidance applies and the outage times you noted are what the decision gets made on.
Then let the crew's supervisor coordinate with you. That conversation, calm and factual, is the whole event handled.
The Night We Remember: A Sandyford Office in the Dark
Back to that stormy evening, because the ten-minute drill is easier to picture than to describe.
Minute one, torches on and the freshly mopped corridor coned at both ends. Minutes two and three, the scrubber drier parked against the wall and unplugged, along with everything else on charge.
By minute five, PowerCheck had the answer: an area fault, restoration estimated in hours, not minutes. The crew phoned our supervisor, who phoned the client contact, so nobody found out by surprise the next morning.
Then they salvaged what the light allowed. The glazed atrium carried enough street light to finish sanitising touchpoints on the ground floor, so that got done. The powered floor work did not, and pretending otherwise helps nobody.
Before leaving, they photographed and logged exactly what was completed and what remained, locked up by torchlight with the building manager, and headed home through the rain. The floor work was completed the following evening in a make-up visit, no drama and no argument, because the contract anticipates nights like this.
The client's facilities manager later told us the part he appreciated was not the cleaning at all. It was being told the same night, with a plan already attached.
Rescheduling, Contracts and Who Carries the Cost
Here is how a professionally run contractor handles a lost or shortened visit, and what you should expect from yours.
The interruption gets logged, with photos, so both sides know precisely where work stopped. The undone tasks are either carried into the next scheduled visit or picked up in a make-up visit within the week. And the contract itself should already say what happens for events outside either party's control, so nobody is negotiating principle at 9pm in a dark lobby.
Worth doing this week rather than during the next storm: read your cleaning agreement and find its missed-visit and force majeure style language. If it has none, ask for some.
Our own practice is plain. Interrupted work is rescheduled at the earliest slot, you are never charged for work that did not happen, and the re-clean guarantee applies to the finished work exactly as normal.
The Dublin Angle: Storm Season, Old Buildings and Planned Outages
Most area outages in Dublin arrive with the Atlantic storm season, and named storms usually announce themselves days ahead through Met Eireann warnings. That notice is the early signal for facilities teams: on an orange or red night, agree in advance whether the clean goes ahead, moves or stands down.
Building type shapes the night too. Georgian buildings with dark cores and single stairwells become properly hazardous without power, while modern Docklands and Sandyford blocks stay walkable but lean on powered access systems that behave unpredictably on battery.
Planned ESB Networks outages are the easy case, because they are notified in advance. The only failure mode is the notice sitting in an inbox and never reaching the cleaning contractor. Forward it, and the visit simply moves.

Build a Simple Outage Plan With Your Cleaning Contractor
The whole plan fits on five lines, and you are welcome to steal it:
- Swap out-of-hours contacts both ways, including building management
- Agree the stand-down rule for Met Eireann orange and red warnings
- Agree the make-up visit window in advance, in writing
- Keep torches in the cleaning store, checked occasionally
- Forward every planned outage notice the day it arrives
We set this up as a matter of routine during the free site survey for contract clients, and it takes ten minutes. Our founder Catalin has one line on the subject that settles every edge case: we would rather lose an evening's work than have anyone cross a wet floor in the dark.
Frequently Asked Questions
What cleaning can be done without electricity? Manual and battery tasks in properly lit areas: dusting, touchpoint sanitising, spot cleaning, sweeping, mopping and battery vacuuming. Machine work, hot water tasks and unlit areas wait for power.
Should cleaners stay in a building during a power cut? Only where lighting and access remain safe. Otherwise the right move is to secure the site, log progress and stand down until power returns.
How do I check when power will be back in my area? The ESB PowerCheck map at powercheck.esbnetworks.ie shows live outages and restoration estimates. Faults are reported to ESB Networks on 1800 372 999.
Who pays if a scheduled clean is cancelled by a power outage? It depends on your contract. A professional contractor reschedules rather than charging for undone work. Check your agreement for missed-visit terms, and ask for them if absent.
What happens to office fridges during a power cut? Keep doors closed and note the outage times. Staff fridges are a judgement call. Catering stock decisions should follow food safety guidance, using the times you recorded.
Are wet floors dangerous during a power outage? They are the biggest immediate hazard in the building. Dry, cone or block every wet floor before anything else happens.
Do cleaning companies have backup plans for outages? The good ones do. Ask a prospective contractor how interruptions are logged, communicated and rescheduled. A blank look is your answer.
How do planned ESB outages affect scheduled cleans? Barely, if the notice is forwarded. The visit moves to another slot and nothing is lost. The only problem is the notice that never gets passed on.

The fire itself lasted minutes. An electrical fault in a printer corner of a Dublin 2 office, caught early, out before the fire brigade even finished checking the building. The soot was a different story. The next morning the office manager found a grey film on desks two rooms away and black webs hanging in […]
A few winters ago, our phone rang at ten past six in the morning. A facilities manager on the other end, standing outside a ground floor office near the Dodder, trying to keep his voice level. The water had come in overnight and gone back out on its own. What it left behind was worse […]
A property manager at a multi tenant office block near Grand Canal Dock rang us on a Tuesday, standing in the bin store while he talked. The mixed dry recycling for the whole building had been tagged as contaminated two collections running, with a surcharge attached both times, and now the bin was overflowing into […]
