Choosing a Commercial Cleaning Vendor: A Checklist
The right cleaning vendor makes your common areas a quiet non-issue. The wrong one becomes a recurring headache of missed visits, surprise charges, and uninsured risk. Before you sign a contract, run prospective vendors through a short, consistent checklist. Here is the one we would hand a property manager vetting any commercial cleaner, including us.
Insurance and bonding come first
This is the line that separates a real commercial vendor from a liability. A crew is working around your residents, your fixtures, and your building’s finishes. If something gets damaged or someone is hurt, you do not want the exposure landing on the property.
- General liability insurance. Ask for a current certificate of insurance, not a verbal assurance. Many commercial clients require coverage limits in writing before any crew is allowed on-site.
- Additional insured status. If your owner or management company requires it, the vendor should be able to name your property as an additional insured on their policy. This is a standard request made directly to their insurer.
- A janitorial or surety bond. Bonding protects you if the vendor fails to deliver or there is a loss tied to their crew. It is a common expectation for vendors working in occupied buildings.
- Workers’ compensation. If the vendor has employees, confirm they carry it, so an on-site injury is their issue and not yours.
One practical tip: check renewal dates, not just whether a document exists. Coverage that lapses mid-contract is one of the fastest ways to end up out of compliance, so build a quick annual check into your vendor file.
Certification and training
Anyone can buy a vacuum. Standards are what protect your floors and your air systems from being cleaned the wrong way.
Look for technicians trained to recognized industry standards, such as the IICRC for carpet and hard-surface care. Certification is not a guarantee, but it tells you the vendor invests in doing the work correctly, using the right method and chemistry for each surface rather than a one-size-fits-all approach that can void a flooring warranty or leave residue behind.
Scope, frequency, and accountability in writing
Vague agreements create vague results. A solid proposal should spell out:
- Exactly which spaces are covered (hallways, lobbies, clubhouse, fitness room, stairwells, shared floors).
- The frequency for each, since a busy entry lobby and a quiet top-floor corridor do not need the same cadence.
- What is included versus billed as an add-on, so a post-event deep clean or a renovation cleanup does not become a surprise line item.
- How issues get reported and resolved, and who your single point of contact is.
If a vendor cannot put this in writing before the contract, expect the same fuzziness in their service.
References and local track record
Ask for references from properties like yours, multi-unit communities, associations, or commercial buildings of a similar size. A vendor who regularly serves the area will understand local realities like Minnesota road salt and slush season, which drives much of the wear on East Metro common-area flooring.
The one-vendor advantage
Most managers end up juggling separate companies for carpet, hard floors, and air systems, which means three schedules, three invoices, and three numbers to call when something slips. Consolidating those trades under one insured vendor is simpler to manage and usually cheaper, because the work can be routed and priced together.
That is the model we built AB CAM Services around: one local, insured crew handling carpet, hard surfaces, and air systems for apartment communities and associations across the Twin Cities East Metro, on a schedule you set once.
Run the checklist, then call
If a vendor clears insurance, certification, written scope, and solid local references, you have found a partner worth a conversation. If you would like us to walk your property and put a clear, no-surprise proposal in writing, book a consultation or call 651-425-1678.

What should a property manager check before hiring a commercial cleaning vendor?
Confirm the vendor carries current general liability insurance and, ideally, a janitorial bond, will name your property as an additional insured if required, holds relevant certifications, and can put scope and frequency in writing. Ask for references from similar multi-unit or commercial properties.
Why does insurance matter so much for commercial cleaning?
Cleaning crews work around residents, equipment, and your building's surfaces. If something is damaged or someone is injured, a vendor without proper coverage can leave the property owner exposed. Many commercial clients require proof of insurance, sometimes naming themselves as an additional insured, before any crew is allowed on-site.
Is one vendor for multiple trades better than several specialists?
For most properties, yes. Bundling carpet, hard-surface floors, and air systems under one insured vendor means one schedule, one invoice, and one point of contact instead of chasing three companies. It is usually simpler to manage and easier to price.
What is IICRC certification and should I look for it?
The IICRC sets widely recognized standards for cleaning and restoration. A vendor whose technicians are trained to those standards is more likely to use correct methods for your flooring and avoid damage. It is a useful credibility signal when comparing bids.
