The short answer
There is no single going rate for warehouse floor cleaning in Houston, and a reliable rate depends on seeing the floor, in person or in photos. Machine scrubbing is priced per job, and the range is wide: market rates run from a few cents per square foot for very large floors on frequent recurring programs to well over twenty cents per square foot for small, heavily soiled, one-time jobs. Both ends of that range are accurate for different floors.
What you can count on is the shape of the pricing. Bigger floors cost less per square foot. Recurring visits cost less than one-time deep scrubs. Heavy soil costs more than dust. And a quote that leaves any of that out is not a quote you can compare.
What actually sets the price
Five factors set the price. Timing affects the schedule more than the price: the windows you can offer, between shifts, overnight, or a shutdown weekend, decide when the work happens.
1. Square footage
Square footage is the biggest factor, but not a linear one. Every job carries fixed costs regardless of size, such as the walkthrough and the setup. On a 10,000 square foot floor those fixed costs are most of the bill. On a 100,000 square foot floor they are a rounding error, and nearly all of the bill is the scrubbing itself.
2. Open floor vs. racked floor
Open concrete costs the least per square foot to clean. Racking adds edge work along every upright and hand-finishing in the corners of every aisle. The square footage is the same; the hours are not.
3. Soil load
Light dust costs the least to clean. Forklift tire marks need chemistry made for rubber, and oil-soaked shop concrete needs a degreaser and more labor. A floor with drywall dust from construction takes extra dry pickup first. Tell the contractor what is on the floor, or send a photo of the worst area. It changes the number more than anything except size.
4. First scrub vs. maintenance
On a floor that has never been machine-scrubbed, the first visit removes years of buildup and uses more chemistry than any visit after it. That first scrub costs the most. Every visit after it costs less, because there is less to remove.
5. Frequency
A standing program, weekly to quarterly, gets a fixed per-visit price below the one-time rate. The visit is scheduled in advance, the floor never returns to the “needs a deep scrub” state, and the cost becomes a predictable line item. For a distribution floor with daily forklift traffic this is usually the cheapest way to own a clean floor over a year.
Why the per-square-foot rate falls with size
Think of the job as two parts: a fixed setup cost and a variable cost per square foot of scrubbing. On a small floor the fixed part dominates, so the effective rate per square foot is high. As the floor grows, the fixed cost is spread across more feet and the effective rate falls toward the variable cost alone. That is why a 100,000 square foot shell can be quoted at a small fraction of the per-foot rate of a 10,000 square foot shop.
One-time vs. recurring: the math of soil
A one-time deep scrub removes the soil that has built up since the floor was last cleaned. If that is five years of buildup, the first visit is priced for it. A recurring program removes a week or a month of soil per visit, so each visit is short, and the floor stays clean all year instead of only after a deep scrub.
The first deep scrub restores the floor; a program keeps it there at a lower per-visit price.
What a good quote includes
A quote you can actually compare has one number and lists what is inside it:
- A walkthrough or photo review and a written scope of which areas are included
- Methods and products matched to the floor type
- Chemistry matched to the soil (tire-mark cleaner, degreaser, or neutral cleaner)
- After-hours, weekend, or between-shift scheduling
- Edge and detail work along walls, racking, and fixtures
Then ask what it does not include. Common exclusions worth knowing about: moving product or pallets, mechanical removal of cured adhesive or heavy mortar, strip-and-wax on VCT, and anything above the floor.
Red flags
- A per-square-foot rate given before the contractor has seen the floor, in person or in photos. It will change once the floor is seen.
- “Plus conditions.” An open-ended line leaves the final price undefined.
How Maddox prices it
Maddox quotes every warehouse floor cleaning job individually, from a $500 minimum visit, and replies to every request within one business day. The pricing page lists the factors, and the quote includes everything in the list above. Recurring programs are priced per visit, below the one-time rate, on month-to-month terms after the first 90 days. Request a quote with the square footage, the floor type, and a photo of the floor to receive a single figure and the reasoning behind it.
