Commercial disinfection services: what the work actually is, and what it adds to a cleaning rate

What the companies publish

How to price disinfection without buying a word

1. Name the surfaces, not the building. Disinfection is bought by touch point, not by square footage. Door furniture, switch plates, shared desks, lift buttons, taps, handrails and keypads are the list almost every specification settles on. Count them, because a price per square foot applied to a whole building tells you nothing about whether those surfaces are being treated at all.
2. Ask for the product and its contact time. Every registered disinfectant publishes a dwell time on its own label, and it ranges from under a minute to ten. A contractor who names the product is quoting a method you can check; one who says hospital-grade is quoting an adjective. This single question separates a real disinfection line from a marketing one.
3. Set the frequency separately from the clean. Most buildings do not need every surface disinfected every night, and the ones that do are usually clinical. Daily touch points with a weekly wider pass is a common shape and a much cheaper one than a blanket nightly figure, so specify frequency per surface group rather than accepting one number for everything.
4. Treat fogging and electrostatic spraying as a separate line. Electrostatic application is a delivery method, not a different chemical, and it is priced as an event rather than as part of the round. If it appears in a proposal, it should carry its own unit and its own frequency, because it is the line most likely to be sold as a recurring cost when it was bought as a one-off.

Common questions

What do commercial disinfection services cost?

Nobody in this record publishes a disinfection-only rate. What two of them publish is a specialty or deep-cleaning uplift on top of the standard per-square-foot figure, which is the honest shape of the answer: disinfection is an addition to a clean, and the addition is what varies.

Is disinfection the same as sanitising?

No, and the difference is regulatory rather than rhetorical. Sanitising reduces a surface's microbial load to a stated level; disinfecting kills a named list of organisms under a named contact time. A specification that uses the two words interchangeably has not decided what it is buying.

Does a general janitorial contractor do this?

Most will. The question is not whether they say yes, it is what the written scope says about product, contact time and touch-point frequency. All three belong in the contract, not in the sales conversation.

Is a certificate worth anything?

A completion certificate records that a visit happened. It is not evidence that contact time was met, which is why the specification matters more than the paperwork.
