You buy it through an independent insurance broker. Most standard insurers and online quote sites will not sell it to contractors, so a broker shops it across specialty insurance companies for you, usually in 2 to 10 business days. The policy is called contractors pollution liability: coverage for fumes, dust, spills, or mold caused by your work. Who this is for: any contractor whose contract lists "pollution liability" or "environmental impairment."
The short version
- Your general liability policy has a pollution exclusion. It removes most claims about fumes, dust, spills, chemicals, and fuel. Mold is removed by a separate page.
- The policy your contract wants is called contractors pollution liability. It fills that gap for your work and your subs' work.
- You buy it through a broker from specialty insurance companies. Very few sell it online.
- Plan on 2 to 10 business days, a short application, and a description of what you do.
- Illustrative cost for a small trade at a $1,000,000 limit is about $1,500 to $7,500 a year, or $2,500 and up for a single job.
Why doesn't my general liability policy already cover this?
Almost every general liability policy has a pollution exclusion. In plain words, it does not pay when something your work released causes harm. That covers fumes, dust, smoke, vapors, chemicals, fuel, and silt. The standard form does give a few things back, and those give-backs are printed in the form, not picked by your insurer: fumes from materials you bring inside a building for your work, fuel or fluid from your own machine, and a hostile fire. What changes is whether your policy adds the two pages below.
| Where it is | What it says in plain English | What it means for you |
|---|---|---|
| Pollution exclusion in the standard policy (CG 00 01, exclusion f) | No pay for injury, damage, or cleanup caused by a release of pollutants. | A spill, a fume complaint, or a dust claim from your work is usually not covered. |
| Total pollution exclusion, a separate page on many contractor policies | Removes even the give-backs above. | Ask your broker whether your policy has one. |
| Fungi or bacteria exclusion (CG 21 67), another separate page | No pay for mold or bacteria claims. | Mold is decided here, not by the pollution exclusion. |
What is the policy my contract is asking for?
It is called contractors pollution liability. It covers pollution claims from work you or your subcontractors perform. Most policies pay for four things:
- Bodily injury to someone who is not your employee.
- Property damage to things you do not own.
- Cleanup costs, including costs a government agency orders.
- Legal defense, often the largest bill. On most pollution policies the defense bill comes out of your limit, not on top of it the way general liability defense does. Ask which way your quote is written.
Many policies also cover pollution while you haul materials. You can buy an annual policy that covers every job, or a project policy for one job. See which one is cheaper.
Where do I actually buy it?
Through a broker. Pollution coverage for contractors comes from specialty insurance companies, often surplus lines insurers (companies that write what standard ones will not). They rarely quote online. A broker sends one application to several of them.
Some insurers bundle general liability and pollution coverage in one contractor package. If your general liability renewal is close, ask your broker to price that too.
How long does it take and what will they ask me?
Plan on 2 to 10 business days. Simple trades with clean records are fastest. You will need:
- A one to three page application.
- A plain description of your work: what you do and what you never do.
- Your yearly revenue and payroll, and how much you sub out.
- Your claims history report.
- The insurance section of the contract.
What does pollution insurance cost?
These figures are illustrative. Your price depends on your trade, your revenue, your state, and your claims history.
| Option | Illustrative cost | Best for |
|---|---|---|
| Annual policy, $1,000,000 limit, small trade | $1,500 to $7,500 a year | Contractors who see this requirement more than once a year |
| Project policy, one job | $2,500 and up, one premium for the job and its tail years | One large or unusual job when you do not expect another |

What should I check before I send the certificate?
Match the contract, not just the word "pollution." Check three things:
- The limit. Most contracts ask for $1,000,000 to $5,000,000.
- Who must be added. Many contracts require the owner or general contractor to be named, so they can use your policy if they get sued because of your work.
- The mold cap. Some policies cap mold claims below the main limit. A cap can get your certificate rejected if the contract wants full limits for mold.
Also check the policy type. Contracts often ask for an occurrence policy, which covers work you did while the policy was active even if the claim shows up years later. Most trade pollution policies are written that way. If limits do not line up, see what to do when requirements exceed your policy.
What this looks like in real life
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A commercial painting contractor in Texas wins a $180,000 repaint of an occupied office building. The contract asks for $1,000,000 of contractors pollution liability with the owner added to the policy. He assumes general liability handles fumes.
What went wrong: He spends a week on online quote sites. None will quote a painter for pollution. The property manager will not release the building until the certificate is complete.
What it cost: The start date slips nine business days, about $6,500 in idle crew wages. A broker then places an annual policy in four business days for an illustrative $2,400.
The fix: Send the contract to a broker the day you get it. The coverage is not expensive for most trades. The delay is the expensive part.
Frequently asked questions
Q: My contract requires pollution insurance. Where can I get it?
From specialty insurance companies through an independent broker. Very few sell it online or direct. A broker sends one application to several of them and usually has coverage in place in 2 to 10 business days.
Q: Does my general liability policy cover pollution at all?
Very little. The pollution exclusion removes claims about fumes, dust, spills, chemicals, and fuel, and a separate fungi or bacteria page removes mold. The form gives a few narrow things back, but many contractor policies delete those with a total pollution exclusion.
Q: What is the policy called?
Contractors pollution liability. Contracts sometimes call it pollution legal liability or environmental impairment liability. Send the exact wording to your broker so the right policy gets placed.
Q: How fast can I get pollution insurance?
Usually 2 to 10 business days from a complete application. Simple trades with no past claims are fastest. Remediation work and past claims take longer, so start the day you see the requirement.
Q: Does it cover work my subcontractors do?
Usually yes, for claims made against you because of their work. The wording varies, so ask your broker to confirm it before you rely on it. Your general liability excludes pollution from your subs' work as well as your own.
Q: Can my customer be added to a pollution policy?
Usually yes, and many contracts ask for it. Tell your broker at the application stage so the wording is there from day one.
