There is no single correct answer, and any contractor offering one without asking about your operation is selling a package rather than solving your problem. Frequency should follow traffic, floor type and what the space is used for.
Start with traffic, not floor area
A 3,000m² cross-dock running three shifts will need attention several times a week. A 10,000m² storage warehouse with two forklifts moving slow stock might be fine fortnightly. Size tells you how long a visit takes; traffic tells you how often you need one.
As a rough starting point before a site visit:
- High traffic — cross-dock, food handling, multi-shift operations: machine pass two to five times a week.
- Medium traffic — standard distribution, single shift, regular forklift movement: weekly, with periodic deep cleans.
- Low traffic — long-term storage, low movement: fortnightly to monthly, with a scheduled restoration cycle.
- Dock aprons and thresholds — regardless of the above, these need attention more often than the main floor, because that is where dirt enters.
The signals you are cleaning too little
Rather than guessing, watch for these. Any of them means the interval is too long:
- Black rubber tyre lanes that no longer come up in a single pass.
- A dull grey film returning within a day or two of cleaning.
- Dust visible on stock or packaging at low level.
- Slip incidents or near-misses at dock thresholds.
- Your cleaner asking for extra hours to get through the same scope.
That last one is the clearest signal and the most commonly ignored. When a maintenance schedule stops holding the line, adding hours to the same schedule rarely fixes it — the floor usually needs a one-off recovery, after which the original frequency works again.
Why more often is often cheaper
This is the part that surprises people. Cleaning a floor weekly is frequently cheaper over a year than cleaning it monthly, because a floor that never degrades needs only a light machine pass. A floor left to build up needs aggressive chemistry, multiple passes and eventually stripping and resealing.
The same logic applies to the sealer. Regular light cleaning preserves it; infrequent heavy cleaning destroys it, and resealing a warehouse floor costs considerably more than several years of maintenance passes.
Match the method to the floor
- Sealed concrete. The most common industrial floor. Regular scrubbing with neutral chemistry preserves the sealer; harsh products strip it prematurely.
- Bare concrete. Porous and absorbs oil, so it needs degreasing rather than scrubbing alone, and benefits most from being sealed.
- Epoxy. Durable but scratches, and abrasive pads dull it permanently. Method matters more here than frequency.
- Food-grade areas. Frequency is usually set by your audit requirements rather than by appearance, and documentation is part of the job.
Build the schedule in layers
The most cost-effective schedules are not one frequency applied everywhere. They usually look like this: a frequent light pass on traffic lanes and dock areas, a less frequent full-floor pass, and a periodic deep clean or restoration once or twice a year.
That structure keeps the areas that degrade fastest under control without paying to clean slow-moving zones at the same rate.
