Commercial cleaning: what to know

What the job involves, what changes the price, and what to ask a pro.

What commercial cleaning is

Commercial cleaning keeps offices, shops, clinics and other business spaces clean on a schedule, usually after hours so staff and customers are not in the way. Businesses use it to keep restrooms sanitary, floors safe to walk on and shared surfaces in an acceptable state day after day.

Signs you need it

  • Restrooms run out of supplies or go a full day without a complete clean
  • Trash and recycling pile up between pickups and draw pests or odors
  • Break room sinks, microwaves and fridges are sticky and no one has a clear duty to clean them
  • Carpets and hard floors show traffic lanes and scuffs that daily sweeping does not fix
  • Your staff are spending time on cleaning instead of on the work they were hired to do

What the pro does

  • Walk the space with the manager to map high-traffic areas, restrooms, break rooms and any restricted zones
  • Empty trash and recycling, replace liners and restock paper products, soap and sanitizer
  • Clean and sanitize restroom fixtures, floors and partitions, and wipe mirrors and dispensers
  • Dust desks, shelves and window sills, and wipe high-touch surfaces such as door handles and light switches
  • Clean break room counters, sinks and appliance exteriors, and remove food from the fridge if requested
  • Vacuum carpets and mop hard floors, and leave a log or checklist so the manager can confirm the work

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Square footage and the number of floors or separate suites that need service
  • The number of restrooms, break rooms and kitchens that need full attention each visit
  • How often the space is cleaned, such as daily, several nights a week or weekly
  • Whether the crew works after hours only or during limited business hours
  • Industry-specific requirements such as medical, food or childcare settings that need stricter procedures
  • Specialty services such as carpet extraction, window cleaning or floor stripping

What a written quote should spell out

  • A written scope listing each area, the tasks in each area and the frequency
  • Which supplies are provided by the company and which the business must stock
  • The access plan, including keys, key cards and alarm codes and how they are controlled
  • The insurance coverage the company carries and how a damage claim is handled
  • The terms for changing the schedule, adding a space or ending the contract

Questions to ask before you hire

  • Are your cleaners insured and are they employees or contractors
  • How do you check the work each night, and what log or sign-off do I get
  • Do you have a process for restricted areas, such as server rooms or labs
  • What products do you use on restroom fixtures, floors and break room surfaces
  • How do you handle a complaint from a staff member about a missed area
  • How do you secure keys and alarm codes, and who on your team has access

Red flags

  • No written scope, which leaves every visit open to interpretation
  • A company that wants unrestricted key access with no record of who holds keys
  • No insurance information when you ask for it
  • Promises to clean every area to a level the scope does not describe

What you can do yourself

Staff can keep their own desks, personal kitchen items and trash clear between visits, and report spills or restroom supply shortages right away. Call a professional for floor care, restroom sanitizing, carpet extraction and any work near equipment or restricted areas.

Licenses and permits

Commercial cleaning is not commonly licensed as a trade. Check with your state or local licensing agency for business registration and any requirements for food service or healthcare spaces that apply to the site.

Commercial cleaning questions

Should the cleaning crew work during business hours?

Most commercial cleaning happens after hours to avoid disruption. If you need daytime cleaning, say so when you request a quote, because it changes the crew and the scope.

Who supplies the paper products and soap?

This is set in the contract. Some companies supply everything, some supply only the cleaning chemicals. Decide before you sign, and write it into the scope.

How do I know the work was done?

Ask for a nightly or weekly checklist with sign-off. A written log makes it easy to see what was cleaned and to raise problems quickly.
