The lowest of three bids for cleaning a Tulsa office building is usually the one that skipped something, and most often that something is workers’ compensation coverage or a written scope of work. Business owners and facility managers tend to treat three quotes as the same product at three prices. They rarely are. Knowing what to look for when hiring a cleaning company means checking the things that never show up on the quote itself: who insures the workers, who screened them, and what exactly they agreed to do in your building. A certificate of insurance takes about five minutes to request, and a company that hesitates to send one has already answered your most important question.
Insurance and Workers’ Compensation Come First
Every other item on your checklist depends on this one. A cleaning crew works in your building after hours, on ladders, around wet floors, and with chemicals. If someone is hurt or something is damaged, the question of who pays lands on whoever holds the right policy. The U.S. Small Business Administration explains that general liability business insurance protects against bodily injury, property damage, medical expenses, and lawsuits, and that businesses with employees must carry workers’ compensation. A cleaning company with staff on payroll is required to carry it. One that does not is either working with contractors it does not control or cutting a corner that becomes your problem.
What you ask for is a current certificate of insurance naming you as an additional insured. The certificate lists the insurer, the coverage type, the policy limits, and the effective and expiration dates, so you can see in one page whether the coverage is real and whether it is still in force. In Oklahoma you can go a step further. The Oklahoma Workers’ Compensation Commission offers a public coverage lookup that lets you verify an employer’s workers’ comp coverage yourself rather than taking the salesperson’s word for it. Vague answers about insurance or an expired certificate are the red flag here, and they are disqualifying for any commercial contract, whether the buildings involved are a single office suite or a portfolio of properties.
Employee Screening and Who Actually Does the Work
Cleaning staff hold keys, alarm codes, and unsupervised access to desks, files, and server rooms. Employee screening is the second thing to look for, and it has two parts. First, ask for the company’s written screening policy. The Equal Employment Opportunity Commission and the Federal Trade Commission note that third-party background checks must comply with the Fair Credit Reporting Act and require written permission from the applicant, so a company that runs them properly will have a documented process, not a verbal assurance.
Second, ask whether the work is subcontracted. Some companies quote a job, then hand it to a subcontractor whose workers were never screened under the policy you were shown. You want to know whether the people cleaning your building on a Tuesday night are employees of the company you signed with and whether the same crew will be assigned to your account. The red flag is no policy at all, or crews that change without notice. Consistent staffing is what makes accountability possible; if a different person shows up every week, nobody owns the results.
A Written Scope of Work and Clear Contract Terms
A price without a scope is not a bid, it is a guess. A proper scope of work lists rooms, tasks, frequencies, and supplies: which restrooms get serviced nightly, which conference rooms get vacuumed weekly, whether the vendor supplies paper products and liners, and who handles the kitchen. The Better Business Bureau’s hiring tips say any business considered for hire should be registered, bonded, and insured, and that a written agreement should spell out what the cleaners will do and the timeframe for doing it. That advice was written for homeowners, and it applies twice as hard to a commercial facility with tenants, visitors, and compliance obligations. The red flag is a one-line quote with a price and nothing else.
Contract terms deserve the same attention. Ask about the term length, the exit clause, and the rules for price adjustments. A 12-month agreement with a 30-day termination clause for unresolved performance issues protects you; an auto-renewal with no way out does not. You should also know how adding a floor or dropping a service changes the monthly number, and whether holiday schedules or one-time projects like floor stripping are priced separately. If you want to see what a written scope looks like before you compare anyone’s numbers, contact Premier Janitorial to request a Free Facility Assessment for your Tulsa building.
References, Safety Training, and Communication
References are worth checking only if you check the right ones. Ask for two or three current commercial clients with similar buildings, then call them and ask specific questions: how long the same crew has been assigned, how complaints get handled, and whether the scope has been honored. Only residential references, or none at all, is a red flag for a commercial job. A company that cleans a multi-tenant office building deals with a different set of expectations than one that cleans houses.
Safety training protects your building as much as the workers. OSHA lists the cleaning hazards the industry faces, including cleaning chemicals, bloodborne pathogens, slips, trips and falls, falls from elevation, and the need for personal protective equipment. Ask to see the training program for chemicals, slips, and PPE. If the staff cannot say what a safety data sheet is, the training program does not exist in any practical sense, and that is the red flag to watch for.
Communication is the last criterion and the one that determines whether the other six matter after the contract is signed. You want a named point of contact and an inspection or reporting schedule, so that problems get raised and fixed before a tenant raises them for you. Calls that go to voicemail with no callback during the sales process will not improve once you are a customer.
What to Look for When Hiring a Cleaning Company: The Hiring Criteria Table
The table below puts the seven criteria from this post side by side, with the document or answer to request and the warning sign that should stop the conversation.
| What to look for | What to ask for | Red flag |
|---|---|---|
| Insurance and workers’ comp | A current certificate of insurance naming you as an additional insured | Vague answers about insurance or an expired certificate |
| Employee screening | The written screening policy and whether the work is subcontracted | No policy at all, or crews that change without notice |
| Written scope of work | Rooms, tasks, frequencies, and supplies in writing | A one-line quote with a price and nothing else |
| References | Two or three current commercial clients with similar buildings | Only residential references, or none at all |
| Safety training | The training program for chemicals, slips, and PPE | Staff cannot say what a safety data sheet is |
| Contract terms | Term length, exit clause, and rules for price adjustments | Auto-renewal with no way out |
| Communication | A named point of contact and an inspection or reporting schedule | Calls go to voicemail with no callback |
A company that clears all seven rows may still not be the cheapest bid on your desk, but it is the one whose price means what it says.
Red Flags That Should End the Conversation
Some warning signs are subtle and some are not. The following behaviors during the sales process are the not-subtle kind, and any one of them is reason enough to move on to the next bidder.
- Pressure for an immediate decision. A commercial cleaning contract is a recurring monthly expense, and a company that needs your signature today is usually worried about what you will find tomorrow.
- Cash-only payment or a reluctance to invoice. Legitimate commercial vendors invoice on terms and can be paid by check or transfer, which also gives you a paper trail if a dispute arises.
- No written scope, or a refusal to put verbal promises in the agreement. If the salesperson says the crew will handle the kitchen nightly, that sentence belongs in the contract.
- Hesitation over the certificate of insurance. The document exists, the insurer produces it on request, and the only reason not to send it is that it does not say what you were told.
- Inconsistent answers about who does the work. If the first call says “our employees” and the second says “our partners,” ask directly whether the job is subcontracted and get the answer in writing.

Conclusion
The bid that wins on price alone often wins because it left something out, and the missing pieces are predictable: workers’ compensation coverage, a written scope, screened employees, or a contact who calls back. What to look for when hiring a cleaning company comes down to seven criteria, each with a specific document or answer you can request and a specific warning sign you can watch for. Request the certificate of insurance, verify the workers’ comp coverage through the state lookup, read the scope before you read the price, and call references who run buildings like yours. Five minutes of verification on the front end saves months of frustration after the contract is signed, and it tends to separate the Tulsa cleaning companies that expect to be checked from the ones that hope you will not.

Frequently Asked Questions
What questions should I ask a commercial cleaning company before signing?
Ask for a current certificate of insurance that includes workers’ compensation, and ask whether you can be named as an additional insured. Ask whether the work is subcontracted, how employees are screened, and whether the same crew will be assigned to your building. Then ask for the scope of work in writing, along with the contract term and exit clause.
What certifications should a commercial cleaning company have?
No certification is legally required to clean commercial buildings, so treat certifications as a signal rather than a requirement. Industry programs such as ISSA’s CIMS use an independent third-party assessor to verify management and training practices. Insurance, workers’ compensation, and documented safety training matter more than any certificate.
What are the biggest red flags when evaluating a cleaning company?
Pressure for an immediate decision, cash-only payment, and the absence of a written scope are the three most common warning signs. Vague answers about insurance, crews that change without notice, and references limited to residential work are also reasons to keep looking.
What contract terms should I negotiate with a cleaning company?
Negotiate the term length, a termination clause tied to unresolved performance issues, and clear rules for how prices adjust when the scope changes. Make sure the written scope is attached to the contract, and avoid automatic renewals that lock you in without a review.
Should a commercial cleaning company be insured and bonded?
Yes. General liability insurance covers bodily injury and property damage, workers’ compensation covers an injured employee’s medical costs and lost wages, and a bond offers protection against theft or dishonesty. Without them, an accident or loss in your building can become your expense.
