Most businesses do not switch janitorial companies because of one bad night. They switch because of a slow pattern: missed trash in one office, a restroom that is never quite stocked, a supervisor who stops answering. The best way to avoid that pattern is to ask the right questions before you sign.
This guide lists the 12 questions we recommend facility managers, office managers and property managers ask any commercial cleaning company, including us. It is written for businesses in Redmond, Bellevue, Everett, Bothell and Kent, where tech offices, medical suites, warehouses with attached offices and apartment communities all have very different needs.
Before you call anyone, write down what you actually need cleaned. A clear scope is what makes quotes comparable. Without it, one company might price a nightly full clean while another prices a light weekly tidy, and the cheaper number looks better than it is.
Ask for the business license and a certificate of insurance before service starts. General liability protects your property, and workers' compensation coverage matters if a cleaner is injured on your site. A reputable company will provide documentation without hesitation.
Some companies sell the contract and hand the work to a rotating subcontractor. That is not always a problem, but you should know who is actually entering your building and who is accountable for them.
Ask about background checks, onboarding, and how cleaners learn your specific checklist. Consistency depends on the same trained people returning to your site.
After-hours cleaning means handing over access. Ask how keys and badges are stored, who has them, and what happens if an alarm is triggered or a door is left unlocked.


A professional janitorial company should put the scope in writing: which rooms, which tasks and how often. Generic office cleaning language leaves too much room for missed work. The checklist is what you will hold them to.
Ask who inspects the work and how often. Some companies use supervisor walkthroughs, others use photo check-ins or inspection reports. The method matters less than having one.
Every crew misses something eventually. What separates good companies is how fast they correct it. Ask how you report an issue, who responds, and how quickly a correction is made.
You want one person who knows your building and answers the phone. Being routed through a call center every time a restroom runs out of paper towels is a warning sign.
Commercial cleaning is usually priced by square footage, frequency, restroom count, floor types and the level of detail required. Ask for a walkthrough-based quote instead of a phone estimate, and ask what is included versus billed separately.
Clarify whether the quote includes cleaning chemicals, equipment, trash liners, paper products and hand soap. Consumables add up, so make sure every quote you compare treats them the same way.
Ask about contract length, notice period for cancellation and how price changes are handled. Be cautious with long lock-in terms before the company has proven itself.
Many buildings need more than routine cleaning: a deep clean before a lease renewal, a post-renovation clean, or unit turns in an apartment community. A company that also handles post-construction cleaning and multi-family property cleaning saves you from managing several vendors.

Most offices with daily staff benefit from cleaning three to five nights a week, with restrooms and kitchens covered on every visit. Smaller or lightly used offices may only need weekly service. The right frequency depends on headcount, foot traffic and how the space is used.
After-hours cleaning avoids disrupting staff and is the most common choice for offices. Early morning or daytime service can work for facilities with restricted night access. The service window should be agreed in writing.
A good contract includes a written scope and checklist, cleaning frequency, service window, supply responsibilities, pricing, quality check process, point of contact and cancellation terms. Anything not in writing is easy to lose track of.
