Hiring a commercial cleaning company sounds simple until the crew stops showing up or the scope never matched what you discussed. The difference between a reliable cleaning partner and a frustrating one usually comes down to what you ask before signing anything.
We put this list together for facility managers across Wayne, Oakland, and Macomb counties who have seen the same pattern: a company looked good on paper, said the right things, then delivered inconsistent results. At CJT Janitorial, we believe the questions below separate a dependable local cleaning partner from one that will waste your time.
A cleaning company that cannot cover absences is a cleaning company that will leave your building dirty on random nights. Ask how the vendor fills gaps when someone calls off. You want a specific answer about backup crew members and a timeline for notification, not a vague promise that coverage is handled.
Good answers include details like a named point of contact who communicates the plan before your next business day. Vague answers like "we'll figure it out" are a red flag worth noting.
Your cleaning crew has access to your building after hours. If something is damaged or someone is injured on-site, you need to know the vendor's coverage protects you. Ask for a certificate of insurance before you finalize any agreement, and confirm it names your property.
A company that hesitates to share documentation is telling you something. At CJT Janitorial, we make an insurance certificate available on request because this should never be a difficult conversation.
Crew consistency affects cleaning quality more than almost anything else. A crew that knows your building learns where dust collects, which doors lock automatically, and where supplies belong. Ask whether the company assigns the same crew to your building or rotates people through a pool of locations each week.
If you hear "it depends on scheduling," press for specifics. You deserve to know exactly who will be in your space.
Background checks, onboarding procedures, and job-specific training vary widely between companies. Some vendors hire quickly and train loosely. Ask what the screening process includes and how long a new crew member trains before working your building unsupervised.
A clear, documented answer here tells you the company takes security and quality seriously. If the answer is short or defensive, keep asking or keep looking.
A cleaning quote based on square footage alone misses the details that matter: flooring types, traffic patterns, restroom count, and areas that need extra attention. Insist on an on-site walkthrough before accepting any proposal. A company willing to quote sight-unseen may not understand your space well enough to clean it right.
CJT Janitorial starts every engagement with a free walkthrough because the only way to scope a building accurately is to see it in person.
Verbal agreements create room for misunderstandings about what gets cleaned and how often. Ask for a written, facility-specific document that lists every task, its frequency, and the service window. This becomes the standard both sides can reference when questions come up later.
If a company balks at putting the scope in writing, that tells you accountability is not part of their process.
When you have an issue at 7 a.m., you need to reach a person who can act on it. Ask whether you will have a named contact or whether calls go to a general line. Find out response time expectations and how after-hours requests are handled.
The right answer is a specific name and a direct number. A good office cleaning partner makes communication effortless, not something you chase.
Ask how the company monitors its own work. Regular inspections, documented checklists, and a clear feedback loop mean problems get caught early. If the vendor's quality process depends entirely on you reporting issues, you are doing their management work for them.
Look for a company that builds inspection and feedback into the service from the start, not one that reacts only after complaints.
Cleaning contracts vary widely. Some lock you in for years with auto-renewals. Others bill per visit with no scope document at all. Ask about contract length, renewal terms, cancellation process, and whether the monthly price is fixed or variable.
A straightforward proposal lays out tasks, frequency, service window, and price in plain language. CJT Janitorial uses fixed monthly proposals so you know what you are paying and what you are getting before the work starts.
Every cleaning company says quality matters. Fewer put a specific process behind that claim. Ask what happens if a task is missed or the result falls short. You want a defined resolution path with a clear timeline, not a vague commitment to "making it right."
The answer to this question tells you whether you are hiring a vendor or choosing a partner.
A few bids from vetted companies is a practical starting point. Collecting many more usually means you have not filtered enough up front. Focus on the quality of the walkthrough and proposal rather than collecting the most quotes.
Yes. Any company that quotes without seeing your space is guessing about square footage, surfaces, restroom count, and traffic patterns. A walkthrough gives the vendor the details needed to build a scope that actually matches your building.
A solid proposal lists tasks, frequencies, service windows, exclusions, and price. It should also note access details, site rules, and the process for adjusting scope later. If the proposal is vague, the service likely will be too.
Ask for a certificate of insurance before signing anything. The certificate should list the coverage type, policy limits, and effective dates. A reputable company will send this promptly and can add your property as an additional insured if needed.
A consistent crew learns your building's layout, priorities, and trouble spots. That familiarity leads to fewer missed tasks and less time spent re-explaining expectations. When crews rotate constantly, quality drops and communication gets harder.
We start with a free, no-obligation walkthrough of your space. We document the tasks, frequency, and service window your building needs, then send a fixed monthly proposal you can review on your own time.
