The certificate your cleaning company hands you looks like proof. It’s really a snapshot, and a narrow one.
A commercial cleaning company’s insurance covers a lot. But four common things sit outside it: damage to the items a crew was actually handling, a cleaning job that has to be done over, anything a worker walks off with, and an injury to the cleaner’s own staff. Whether the vendor’s policy pays for those decides a simple thing. A bad night in your office either costs them or it costs you.
The word “insured” on a proposal tells you a policy exists somewhere. It doesn’t tell you that policy will pay for the vacuum that cracked your glass desk. There’s one document everybody asks for and almost nobody reads closely, and it’s the reason so many of these bills land in the wrong lap.
What the insurance certificate actually proves
The paper you get is a certificate of insurance, usually called a COI. It’s a one page summary an insurance agent fills out. It lists the cleaning company, the type of policy, the coverage limits, and the dates the policy runs.
What it proves is narrow. On the day it was issued, that company carried those policies, and the certificate says nothing beyond that.
It doesn’t prove the policy is still active today. Policies lapse when a premium goes unpaid, and the certificate won’t tell you that happened last month. It doesn’t prove the limits are high enough for a real loss. And it absolutely doesn’t promise that any given claim will be paid, because every policy has a list of things it flatly excludes.
So treat the certificate as a starting point, not a guarantee. The exclusions are where the money actually gets decided, and a cleaning policy has four that matter to you.
Hole one: damage to the things the crew was handling
This is the one that surprises people, so it’s worth getting exactly right.
Standard general liability insurance, the main policy on that certificate, covers accidental damage to your property in a lot of situations. If a cleaner scratches your floor, dings a wall, or chips a built in counter, that’s usually covered. Floors, walls, and anything permanently attached to the building count as real property, and general liability generally pays for that.
The trouble starts with movable things the crew took into their hands. Nearly every general liability policy carries a clause called the care, custody, and control exclusion. In plain terms, it won’t pay for damage to personal property that was in the cleaner’s care at the moment it broke.
Think of a laptop they moved to wipe a desk, a framed print they took down to dust, or the equipment they shifted to vacuum under.
The logic behind the exclusion is that insurers don’t want to cover things you were directly handling, because that’s where accidents cluster. The result for you is a gap. The same policy that pays for a scratched floor may deny a claim for the monitor that got knocked off it, because the crew was holding the monitor and not the floor.
There’s a fix, and it’s a fair question to ask any vendor. A cleaning company can add a care, custody, and control endorsement, sometimes sold as bailee coverage, that closes this hole.
Plenty of good companies carry it and plenty don’t. You won’t know from the word “insured,” and you won’t always see it on a basic certificate, so ask the question directly.
Hole two: when the cleaning has to be done over
Say the crew does a genuinely bad job. Streaked glass, a floor left sticky, restrooms missed. You want it fixed.
That’s not an insurance claim. General liability has a “your work” exclusion, which means the policy doesn’t pay to redo the service the company was hired to perform. Insurance is there for accidents and damage, not for quality.
This matters because it tells you where to look when the work is wrong. The place to look is the contract, not the insurance certificate. What settles a redo is the scope of work, the standard the crew is held to, and what happens when they miss it.
That’s exactly the kind of thing the clauses that decide whether an office cleaning contract works are built to handle. A redo is a service problem with a contract answer, not something an insurer will ever touch.
Hole three: when something goes missing
A cleaning crew has keys, alarm codes, and the run of your office after hours. Now and then, something disappears. A petty cash box, a laptop, a piece of equipment.
General liability doesn’t cover employee theft. It’s built for accidents, and theft is a deliberate act, so it sits outside the policy on purpose.
This gets covered by a completely different document, a janitorial bond. A bond and liability insurance are two different policies, and it’s worth knowing that before you sign, because a company can be fully insured and carry no bond at all. If after hours access to sensitive space worries you, the certificate won’t settle it. Ask whether they’re bonded, and ask separately.
Hole four: when a cleaner gets hurt in your building
A worker slips on a wet floor they were mopping, or strains a back moving furniture. Who pays the medical bills?
Not general liability. That policy excludes the cleaning company’s own employees. The right coverage for an injured worker is workers compensation, and it’s a different policy with its own certificate.
This is your problem and not just theirs. In Pennsylvania, employers are required to carry workers compensation for their staff. If a cleaning company skips it to save money and one of its people gets hurt on your floor, the injured worker’s lawyer will look for any policy that might pay.
That search can reach your business and your own insurance. A vendor with no workers comp does more than cut a corner. They quietly hand you their risk.
So the workers compensation certificate isn’t a nice extra. Ask for it the same way you ask for the liability certificate, and check that the dates are current.
Where your own policy has to pick up
Line the four holes up and one pattern shows through. Every time the vendor’s insurance denies a claim, the loss doesn’t vanish. It moves to the next policy in line, and that policy is usually yours.
If the cleaner’s care, custody, and control gap means their insurer won’t pay for your damaged equipment, you’re left filing on your own commercial property policy or eating the cost. If they carry no workers comp and a claim reaches you, your liability policy answers for it. If they’ve quietly let a policy lapse, the certificate you filed away means nothing, and again the bill is yours.
One thing that catches office tenants off guard: your landlord’s insurance won’t help. A landlord policy covers the landlord’s building and the landlord’s assets. It doesn’t cover your property, your equipment, or your customers’ belongings. So the space between the cleaner’s coverage and your own coverage is real space, and things fall into it.
So the certificate deserves a real look instead of a glance. The gaps aren’t theoretical. They decide who writes the check.
Insurance is only one of the checks before you hire, and the others are in the office cleaning services guide, which makes a good list to work from when you’re collecting quotes.
What to require before you sign
Closing most of this takes about ten minutes and a few specific questions. Don’t accept “we’re fully insured” as an answer. Ask for the certificate, and check five things on it.
- Current dates. The policy period should cover the whole term you’re signing for, and you can ask for a fresh certificate each year.
- Real limits. General liability limits of one million per occurrence are common for commercial work. Make sure the number is large enough for what a serious accident in your space could cost.
- Additional insured status. Ask to be named as an additional insured on their policy. That puts your business under their coverage for claims tied to their work, so their insurer defends you too instead of coming after you.
- A current workers compensation certificate. Separate paper, same importance. Confirm it exists and the dates are live.
- The care, custody, and control endorsement. This is the one nobody asks about. Ask straight out whether their policy covers damage to property their crew was handling, or only the building.
None of this is rude, and a professional company answers all of it without blinking. If a vendor gets cagey when you ask for specifics, that hesitation is information. For the rest of what to confirm before you hand over the keys, walk through the full checklist for hiring a commercial cleaning company.
Read the certificate as what it is. It’s a claim about one day, and your job is to make sure it holds up on the day something actually goes wrong.
Frequently asked questions
Does a cleaning company’s insurance cover damage to my building?
Usually, yes. Damage to floors, walls, and permanently attached fixtures counts as real property, and standard general liability generally pays for it. The gap is movable property. If the crew damages an item they were holding or had moved, the care, custody, and control exclusion can leave that out unless the company carries a specific endorsement for it.
My cleaning company damaged my office. Who pays?
Start with their general liability insurance. Document the damage with photos, report it in writing, and file a claim against the vendor’s policy. If their insurer denies it because of an exclusion, or the company has no active coverage, the cost falls to your own property policy or to you directly. Your landlord’s insurance won’t cover your property, so don’t count on it.
Does the cleaner’s insurance cover a bad cleaning job?
No. General liability has a “your work” exclusion, so it doesn’t pay to redo the service. A poor cleaning is a service and quality issue, which is what your contract and its scope of work are for, not the insurance policy.
What should the certificate of insurance actually show?
At a minimum, an active general liability policy with adequate limits, a current workers compensation policy, and dates that cover your full contract term. Ask to be added as an additional insured, and ask separately whether they carry a care, custody, and control endorsement, since a basic certificate may not spell it out.
If a cleaner gets hurt in my office, am I liable?
You can be exposed if the cleaning company has no workers compensation coverage. That policy is meant to handle an injured worker, and Pennsylvania requires employers to carry it. When a vendor skips it, an injury claim can reach your business and your own insurance, which is why you should confirm their workers compensation certificate before work starts.
