Warehouse cleaning is one of the harder things to price over the phone, and any contractor who gives you a firm number without seeing the site is guessing. Two 5,000m² warehouses in the same estate can be completely different jobs: one is a slow-moving storage facility with a sealed floor in good condition, the other runs three shifts with oil-stained concrete and a food-grade area attached.
This is a guide to how the pricing actually works, so you can compare quotes on something other than the bottom line.
The four pricing models you will be quoted on
Most industrial cleaning quotes use one of four structures, and knowing which you are looking at is the first step to comparing them fairly.
- Fixed monthly or weekly. A set scope at a set frequency for a set price. Easiest to budget, and the most common structure for ongoing warehouse contracts. The risk is scope drift — if it is not written down, it is not included.
- Per square metre. Common for one-off floor work like scrubbing, stripping or sealing. Clean and comparable between quotes, but only if the specification is identical.
- Hourly rate. Usual for periodic and reactive work. Transparent, but the number that matters is hours multiplied by rate, and a cheaper hourly rate with more hours is not cheaper.
- Project price. Used for high-level dust removal, shutdown deep cleans and floor restoration, where the work is defined by outcome rather than time.
A quote that mixes these without saying so is the hardest to compare, and worth sending back for a breakdown.
Seven things that move the number
Floor area is the obvious one and rarely the most important. These matter more:
- Floor condition. A neglected slab needs a one-off recovery before any maintenance schedule makes sense. Quoting a routine clean on a floor in that state guarantees disappointment on both sides.
- Access windows. A site that can be cleaned in one uninterrupted block is far cheaper than one where the crew works in short gaps around despatch. Time lost waiting is time you pay for.
- Racking density. Open floorplate is fast. Tight aisles mean walk-behind machines instead of ride-ons, which changes the hours substantially.
- Food-grade or audit requirements. Colour-coded equipment, approved chemicals, full PPE and documentation all add time, and they are not optional if you are audited.
- High-level work. Beams, sprinkler lines and high-bay fittings need access equipment and often a second person for spotting. Priced as a project, not folded into a nightly rate.
- Dock and external areas. Hardstand and dock aprons need high-pressure equipment and water access, which is a different setup to internal scrubbing.
- Frequency. Counter-intuitively, more frequent cleaning is often cheaper per visit, because the floor never degrades to the point of needing heavy work.
Why the cheapest quote is usually the most expensive
The pattern is consistent enough to be worth naming. A low quote almost always comes from one of three places: hours that are too few for the scope, a scope that quietly excludes docks, high level or amenities, or a contractor who has not accounted for your access constraints and will discover them in week two.
What follows is predictable. The standard slips, you raise it, and either the price goes up to what it should have been or the contractor walks. You have then lost three months and are re-tendering. Comparing quotes on inclusions rather than totals avoids most of this.
Questions worth asking before you sign
- Is the dock apron and external hardstand included, or internal only?
- What happens at high level, and how often?
- Is the floor being maintained, or does it need recovery first — and is that recovery in this price?
- Who supplies equipment, chemicals and consumables?
- Will the same crew attend, and are they inducted to our site?
- Can you provide certificates of currency and police check confirmation before the first visit?
- Is there a lock-in term, and what is the exit notice?
Any contractor worth hiring will answer all seven without hesitating.
What we do
We quote warehouse work after a walk-through, not over the phone, because the floor condition and your access windows change the number more than the square metreage does. The quote states what is included and what is not, and there is no lock-in term.
If you want a number for budgeting, tell us the size, the floor type and roughly when we could get access, and we will tell you honestly whether it is a routine maintenance job or a recovery.
