TL;DR
A walkthrough exists so a bid is priced against the real building rather than a square footage number. Two bids can differ by thirty percent purely because one contractor saw the loading dock and the other did not. The most valuable things covered on a walkthrough are the ones nobody writes into an RFP: access constraints, floor materials, actual occupancy, and who currently does what.
Why the walkthrough matters more than the RFP
A written request for proposal describes the building as the buyer imagines it. A walkthrough shows the building as it is.
The gap between those two is where bad contracts come from. A specification that says "12,000 square feet, office use" hides whether there are two restrooms or nine, whether the entry is carpet or polished concrete, whether the back half is a warehouse, and whether the crew can actually get in at 7 pm.
Every one of those changes the labor hours. And labor hours are what a cleaning bid is, underneath the paperwork. More detail on how those hours become a number is in how commercial cleaning contracts are priced.
What should a cleaning walkthrough cover?
A walkthrough should cover the full floor plan including back-of-house, all restrooms and their fixture counts, every floor material, entry and matting condition, waste volume and collection points, building access and alarm arrangements, actual occupancy patterns, and which tasks are currently handled by staff. Anything skipped becomes a pricing assumption.
The full route, not the tour
Buyers often walk the presentable parts of a building and skip the rest. That is a reasonable instinct and a costly one, because the unpresentable parts are where the labor lives.
Areas that should never be skipped: the loading dock or service entrance, stairwells, the mechanical and storage rooms, the janitorial closet itself, the break room, and any space currently in poor condition. The last one is important. A contractor who has not seen a problem area cannot price fixing it, and will price it later as a change order.
What to measure and note on the walk
Restrooms. Count fixtures, not rooms. A six-fixture restroom is a different job from a two-fixture one, and supply consumption scales with fixtures too.
Floor materials. Note every type and roughly how much of each. Vinyl composition tile with finish, luxury vinyl plank, sealed concrete, tile with grout, natural stone, and wood all demand different chemistry and different periodic cycles. Natural stone in particular limits what can be used on it, since acids etch it permanently.
Entries. Length and condition of matting, door count, and whether the entry faces a parking lot. This drives soil load for the whole building.
Waste. Container count, stream setup, volume per service, and where consolidation happens. Whether a dumpster is fifty feet away or across a lot changes the route meaningfully.
Glass and ceiling height. Interior versus exterior glass, and whether high dusting above standard reach needs equipment. Both are frequently separate services.
Kitchens and food areas. Whether there is a commercial kitchen changes the job category entirely.
Access, which is the most underestimated item
Access is where more contracts go wrong than any other single factor.
The questions worth answering on site: What time can the crew enter and what time must they leave? Who holds keys or credentials, and how are they issued and returned? Is there an alarm, and how are codes managed? Are there interior doors that are locked and who unlocks them? Is there a security desk with a sign-in process? Are there rooms the crew may not enter at all?
That last question is common in professional and financial settings and has real scheduling consequences. If four offices are locked every night, four offices do not get cleaned, and the specification should say so rather than pretending otherwise. The mechanics of handling keys and codes safely are covered in key and alarm access protocols.
Occupancy, honestly
Headcount on paper and headcount in the building are frequently different, particularly in hybrid offices. Ask directly: how many people are actually here on a typical Tuesday, and how many on a Friday?
The answer changes the specification. A building running at forty percent occupancy usually does not need five-day private office service, but it still needs full restroom and entry attention. Visitor volume is a separate and often more important question -- a ten-person office receiving eighty visitors daily is a high-traffic building regardless of headcount.
Who currently does what
This is the question buyers most often forget and contractors most often need answered.
In many buildings, staff already handle tasks informally -- someone runs the dishwasher, someone wipes the conference table, someone takes the recycling out on Fridays. If those tasks silently transfer to the contractor without being priced, they get dropped. If they are assumed to stay with staff but nobody told staff, they also get dropped. Walking the building is the natural moment to sort this out, task by task -- see drawing the line between staff and contracted duties.

Questions worth asking the contractor on the walk
The walkthrough runs both directions. A buyer gets a lot of signal from what a contractor asks and notices.
- What did you notice that I did not put in the specification?
- Which of these floor materials will change your periodic schedule?
- How many hours per visit does this building need, and how did you get there?
- What here would you price as a separate service rather than part of the routine?
A contractor who answers those specifically has walked the building properly. One who answers in generalities has priced a square footage number.
Turning the walk into a document
The walkthrough is only valuable if it becomes a written scope. Notes taken and never transcribed produce the same vague contract the walk was supposed to prevent. The output should list every area, its floor material, service frequency, and assigned owner, plus the access arrangement and explicit exclusions -- the structure described in what a scope of work should list.
FAQ
What happens during a commercial cleaning walkthrough?
A contractor walks the full building including back-of-house, counts restroom fixtures, notes every floor material, checks entries and matting, reviews waste volume and collection points, and asks about access, occupancy, and which tasks staff already handle. The notes become the basis for pricing.
How long does a cleaning walkthrough take?
For a typical small commercial building, a thorough walk usually runs somewhere between thirty minutes and an hour. Larger or more varied buildings take longer. A walk that finishes in ten minutes has almost certainly skipped the areas that determine the price.
Should I get walkthroughs from multiple companies?
Yes, and ideally give each the same information. Bids are only comparable when every contractor saw the same building and priced the same scope. Differences in what they noticed on the walk are themselves useful signal about how carefully each will work.
What should I disclose during a walkthrough?
Everything that affects labor: problem areas, locked rooms, access limits, unusual hours, recent condition issues, and tasks currently handled by staff. Withholding a difficult area produces a low bid that becomes a change order later, which helps nobody.
Why do cleaning bids vary so much for the same building?
Usually because the contractors priced different scopes or saw different parts of the building. Restroom fixture counts, floor materials, access constraints, and periodic work assumptions all move the number substantially, and none of them appear in a square footage figure.
Do I need a written scope after the walkthrough?
Yes. Notes that never become a document produce exactly the vague contract the walk was meant to prevent. The written scope should list each area, its floor material, service frequency, assigned owner, access arrangement, and explicit exclusions.
Every building holds a few surprises that only turn up on a walk, which is why the walk comes before the number. Get a quote and we will come look at the actual site, or read more about commercial cleaning services.
