Airport and transit facilities operate around the clock, so cleaning needs to be thorough, discreet and fit around continuous public use.
This service is built for terminal buildings, transit lounges and aviation support facilities where the doors effectively never close and passenger numbers can swing hard between a quiet Tuesday morning and a peak holiday departure bank. The challenge isn't just volume, it's timing, cleaning has to happen without getting in the way of boarding queues, baggage flow or security screening. We typically work overnight or in the gaps between flight banks, moving through zones in a sequence that keeps disruption to passengers and staff to a minimum. Facility managers dealing with multiple tenants or shared common areas find this useful because it takes the coordination burden off their own team.
Terminal and common area cleaning covers concourses, seating zones, check-in areas and circulation spaces that see thousands of people pass through in a single day, including floor care suited to high-polish or high-traffic finishes. Restrooms get frequent attention given the volume they handle, and high-touch surfaces such as door handles, handrails, self-service kiosks and seating armrests are wiped down as a standard part of the visit rather than an add-on. Because airport facilities don't really have a quiet period, we offer scheduled overnight or off-peak cleaning windows so major floor work, detailing and restocking can happen without competing with passenger movement. For sites with multiple terminals or shared tenancy areas, we can coordinate a rolling schedule that covers each zone at the time it's least disruptive, rather than trying to clean everything at once during a single overnight block.
We complete any required security clearances, site inductions and access arrangements before starting, covering both airside and landside areas depending on the site and the level of clearance required.
We map cleaning windows against flight banks and known peak periods, prioritising overnight or off-peak slots for tasks that need more time, more space or heavier equipment to complete properly.
Crews move through terminals, restrooms and common areas in sequence, working around active queues and staff movement rather than closing areas off or disrupting passenger flow.
At the end of each shift we flag anything needing follow-up, from a fault with fittings to an area that needs extra attention or a supply that's running low.
Airport facilities run to a schedule that doesn't bend for anyone, so our approach starts with understanding your flight banks, peak periods and any security or access restrictions before a single cleaner sets foot airside or landside. From there we build a rolling roster that moves through zones methodically, keeping crews visible enough to be accountable but low-key enough not to interrupt passengers or slow down queues. The steps below outline how a typical arrangement comes together, though every terminal has its own quirks worth mapping first.
Airports don't get a slow season and they definitely don't get a day off, so reliability matters more here than almost anywhere else we work. Dosherm builds crews and schedules around round-the-clock operation, which means we can cover an overnight window every night of the week without it becoming a scheduling headache for your facility team. Discretion is just as important as reliability. A cleaning crew working through a terminal at 4am or moving through a boarding lounge between flights needs to be professional, low profile and aware of their surroundings, not obstructing queues, not leaving equipment where it becomes a trip hazard, and not drawing attention to itself. We keep the standard consistent across every zone, so a restroom near a quiet gate gets the same attention as one near the busiest check-in bank. For a facility manager, that consistency means fewer complaints, fewer surprises, and one less thing to actively monitor during a shift that already has enough moving parts to track.
