Measure office carpet for a cleaning quote by recording the cleanable area, the carpet you can actually reach with a machine, rather than the floor area on the plan. Break the floor into rectangles, measure each in metres, subtract fixed obstructions, and note the traffic lanes separately. On a typical office floor the cleanable area comes in 15 to 30 percent below the plan area, and that gap is where quotes get revised on the day.
Why you should measure before anyone quotes you
You do not need to measure. We do it at the assessment. But having your own number changes the conversation, because it lets you see instantly whether a quote is based on the real floor or on a round guess off the drawing. A provider quoting 500m² on a floor you know has 380m² of reachable carpet is either padding or is going to discover the difference later and revise upward.
It also makes comparing quotes possible at all. Two quotes are only comparable if they are pricing the same area, and the only way to know that is if both state the area they are based on, see what drives commercial carpet cleaning cost.
Cleanable area, not floor area
This is the whole distinction. The architect's plan gives you the floor plate. The machine can only reach what is not permanently occupied.
Subtract these:
- Fixed workstation banks and desk pods that cannot be moved
- Server racks, comms cabinets and anything cabled to the floor
- Built-in storage, fixed cabinetry and compactus units
- Structural columns and service risers
- Any hard flooring, kitchens, bathrooms, entrance thresholds, hard-floored breakout areas
Do not subtract these:
- Chairs, pedestals and freestanding furniture, we move them as part of the service
- Light meeting tables and freestanding storage
- Anything on castors
The line is whether it moves. If it moves, the carpet under it is cleanable and gets cleaned.
The practical method
1. Break the floor into rectangles
Do not try to measure an L-shaped or irregular floor as one figure. Split it into rectangles that follow the room divisions, measure length by width in metres for each, and add them. Boardroom, corridor, open-plan bay one, open-plan bay two, and so on. Rectangles are quick and the arithmetic is checkable by someone else.
2. Measure in metres, to the nearest 0.1m
Centimetre precision is wasted effort on a floor this size. A laser measure makes it a ten-minute job on a whole floor and they are inexpensive. A tape works fine.
3. Measure the room, then deduct
Measure each rectangle wall to wall first, then deduct the fixed obstructions inside it. Deducting as you go is where mistakes happen. Room total minus obstructions, written down separately, is auditable later.
4. Mark the traffic lanes separately
This is the step that most improves your quote, and almost nobody does it. Traffic lanes are perhaps 15 percent of the area but carry most of the soil and need the most work, see why traffic lanes go dark first. Noting them, lift lobby to reception, reception to the pods, the run to the kitchenette, lets a provider quote the floor accurately instead of averaging across it. It is also what makes interim maintenance on just the lanes possible as a cheaper option between deep cleans.
5. Note the things that change the price but are not area
Alongside the number, record the carpet construction, tiles or broadloom, see carpet tiles vs broadloom; any wool or wool-blend areas, common in boardrooms; lift access and which lift you may use; parking distance from vehicle to floor; the hours you can give us; and the problem areas, coffee stations, entrances, anything with a history.
The two mistakes that matter
Quoting off the plan. Plans show the floor plate as designed, not as occupied. Fit-outs, added storage and workstation banks all landed after the drawing was issued. The gap between plan and reality is routinely a fifth of the floor.
Measuring in square feet or off a lease schedule. Lease areas frequently include a share of common parts and are measured to conventions that have nothing to do with carpet. Use your own metres.
What we do with it
Your number is a cross-check, not a substitute for the walk-through. We still need to see the floor, because area is only one of the drivers and the assessment is also reading soil load, fibre, access and condition. But arriving with a measured floor plan and marked traffic lanes shortens the assessment, and it means the fixed quote we give you is one you can already sanity-check, see how to choose a commercial provider.
Common questions
How do I measure office carpet for a cleaning quote?
Break the floor into rectangles following the room divisions, measure each in metres to the nearest 0.1m, add them, then subtract fixed obstructions such as workstation banks, server racks, built-in storage, columns and any hard flooring. Do not subtract chairs or freestanding furniture, since those get moved and the carpet under them is cleaned. Mark the traffic lanes separately.
What is the difference between floor area and cleanable area?
Floor area is the plate on the plan. Cleanable area is the carpet a machine can actually reach once fixed workstations, server racks, built-in storage and hard flooring are excluded. On a typical fitted-out office the cleanable area runs 15 to 30 percent below the plan area, which is why quotes based on drawings tend to get revised once someone walks the floor.
Should I subtract furniture when measuring?
Only fixed furniture. We move chairs, pedestals, light tables and anything on castors as part of the service, so the carpet beneath them is cleanable and should be included. Subtract only what genuinely cannot move: fixed workstation banks, cabled server racks, built-in cabinetry and compactus units. The test is simply whether it moves.
Do I need to measure before requesting a quote?
No, we measure at the on-site assessment. Having your own figure is useful as a cross-check, because it shows immediately whether a quote is based on the real floor or a guess off the plan, and it makes competing quotes comparable since they are only comparable if they price the same area.
