The short answer, by traffic
| Floor and traffic | Suggested cadence |
|---|---|
| 3PL, cross-dock, and fulfillment floors with all-day forklift traffic | Weekly or biweekly |
| Distribution floors with moderate forklift traffic | Biweekly or monthly |
| Manufacturing floors with oil, coolant, or metal fines | Weekly to monthly, timed to shifts |
| Light storage, low-traffic warehouses | Monthly or quarterly |
| Warehouse offices, retail, gyms, and other finished hard floors | Monthly or quarterly |
| New construction and tenant turnover | Once, then start a cadence |
These are starting points. The floor, the doors, and what you store on it move the answer in one direction or the other.
What moves the cadence
Forklift traffic
Forklifts do three things to a floor: they polish the lanes, they transfer rubber at every turn, and they grind whatever grit is on the surface into it. The more trips per day, the faster the lanes go gray and the tire marks go black. A floor with a dozen forklifts running two shifts is not the same floor as a storage building with one pallet jack, even if the square footage matches.
The floor itself
Unsealed concrete sheds fine particles from its surface continuously. That is the gray dust on the bottom rack level and on top of every box. Every forklift pass breaks a little more loose. Unsealed floors need scrubbing more often simply to keep the dust down. Sealed, densified, and polished floors shed far less, hold soil on the surface where a scrubber can lift it easily, and can stretch to a longer cadence.
The doors
Every open dock door pulls in grit, sand, leaves, and rain. Buildings with many active doors, or doors that stay open, bring in more soil per day than a closed building. In Houston, spring pollen and late-summer dust seasons are when floors near the docks fall behind fastest.
What you store
Food and beverage, pharmaceuticals, electronics, and anything shipped to customers who inspect the packaging all have a lower tolerance for dust than a building full of steel. If your customers walk the floor, or your product is sensitive to what settles on it, lean toward the shorter cadence.
The signs you are overdue
- A gray film in the traffic lanes that a dry sweep does not change.
- Dust on the lowest rack level and on product that has been sitting a week.
- Black tire tracks at every aisle end and dock apron that have stopped lightening.
- A haze of dust in the air when forklifts move, visible in a dock-door beam of sunlight.
- Slick spots near the docks after rain, where grit and moisture combine.
- Complaints from the night crew about what ends up on their boots and the forklift seats.
If two or more of those are true, the floor needs a deep scrub now and a program after it.
Why waiting costs more
A floor that is scrubbed on a cadence is always removing a few weeks of soil, so each visit is short and routine. A floor that waits a year is removing a year of soil, embedded by a year of forklift traffic. That first scrub is slower, uses more chemistry, and costs more than any single program visit. The cheapest way to own a clean floor over a year is to never let it get to the deep-scrub state.
Frequency by building type
Distribution and 3PL: biweekly is the common answer, weekly for cross-dock and high-throughput floors. Dock aprons and staging areas get the extra pass every visit.
Manufacturing: cadence follows the process. A machine shop with coolant mist and metal fines may need weekly scrubbing of the production floor between shifts; an assembly floor may be fine monthly.
Cold storage and food distribution: dry storage and anterooms follow the distribution rule. Regulated production areas are a sanitation program, not a floor-scrubbing cadence.
Warehouse offices and break rooms: monthly scrubbing keeps VCT and tile from developing the gray traffic pattern that a nightly mop leaves behind.
New construction: one heavy scrub after the last trade and before racking, a lighter re-scrub after racking install if it kicked up grit, then start the cadence once the tenant is operating.
A note on Houston
Humidity keeps dust airborne longer, and it eventually settles as a film on the floor. Pollen season coats everything near the doors in spring; dust season does it again in late summer. Floors that are scrubbed monthly for most of the year often benefit from a biweekly stretch in those windows.
How Maddox sets a cadence
Maddox walks the floor, evaluates the traffic and the doors, and recommends a starting cadence. The recurring program begins with a baseline deep scrub, then runs on a standing day at a fixed per-visit price. If the floor holds up better than expected after a few visits, the cadence is extended; if it falls behind, the cadence is shortened. Terms are month-to-month after the first 90 days, so the schedule follows the building rather than the contract.
