Yes. Your contract sets a total liability limit, and almost no contract says one insurance company has to write all of it. Brokers meet big limits by stacking policies from two or more insurers, like floors in a building, and a claim moves up a floor only when the floor below is used up. Who this is for: contractors asked for $5,000,000 or more.
The short version
- Your contract sets a total limit. It rarely says one company must provide all of it.
- Big limits are built in layers: general liability, then an umbrella, then more policies on top.
- Each layer can come from a different insurance company.
- Every layer should match the one below it, and each can still add exclusions of its own.
- Stacked layers take longer to set up. Start the week you get the contract.
Why would I need more than one insurance company?
Most insurers that write small contractors cap what they will put on one business. Many stop at a $1,000,000 or $2,000,000 umbrella. Almost none hand a 12 person framing crew a single $10,000,000 policy. So your broker builds it. An umbrella (a second layer of coverage above your other liability policies) goes on top of your general liability. If that insurer stops short, another writes a further layer, called excess liability.
How do the layers work together?
Think of it as floors in a building. A claim starts on the ground floor and moves up only when the floor below is used up. Brokers call the finished stack a layered tower. There is one exception. A true umbrella can be a little broader than the policy under it, and if it covers a claim your general liability does not, it can pay first, after you pay the first part of the claim yourself, often $10,000.
| Layer | Who writes it | When it pays |
|---|---|---|
| Your general liability and auto policies | Your current insurers | First, on any covered claim |
| First umbrella (sits on your general liability) | An umbrella insurer, often a different company | After a policy below it is used up, or first on a claim only the umbrella covers |
| Layer on top of that | A third insurer | After the first umbrella is used up |
Each policy above should be written to match the one below it, so a claim covered on the ground floor is covered on every floor above. Insurers call that follow form. A layer is never broader than the one under it, and it can be narrower, because most upper layers add exclusions of their own. Ask for the exclusion list on every layer.
What does my customer need to see?
Your certificate of insurance (a one page summary of your policies, limits, and dates) has one row for umbrella and excess. A third layer gets typed into the description box or issued on a second certificate. The certificate is only a summary and does not prove a layer matches the one below it. See umbrella and excess on a certificate.
Two rules trip people up. Many contracts set a financial strength rule, often A- or better, and every company in the stack has to meet it. Most public jobs also want insurers licensed in your state, and upper layers usually come from specialty insurers that are not. If the contract wants your customer able to use your liability policy when they get sued over your work, that has to reach every layer, and most umbrellas do it only where a written contract required it.
What can go wrong when the layers come from different companies?
| Problem | What it looks like | How to avoid it |
|---|---|---|
| One layer does not match the one below | The upper policy has exclusions the umbrella does not | Have your broker confirm the match in writing, then compare the exclusion lists |
| Dates do not line up | One layer renews in March, another in July, so an April claim hits a gap | Match the dates when you buy |
| An insurer is not rated well enough | The certificate is rejected over a B rated company | Give your broker the rating rule first |
| Cover for your customer stops at one layer | The umbrella protects your customer, the layer above does not | Get the wording on each layer |
One umbrella often takes a day to two weeks. Two or three layers usually take two to four weeks, because each insurer wants the layer below it in place first. See commercial umbrella insurance and umbrella versus excess.
What does a stack of policies cost?
These figures are illustrative. Your price depends on your trade, payroll, the states you work in, and your claims history.
| Layer | Illustrative yearly cost for a small commercial trade |
|---|---|
| First $5,000,000 umbrella | Roughly $6,000 to $20,000 |
| Next $5,000,000 above that | Roughly $3,500 to $12,000 |
| Next $5,000,000 on top | Roughly $2,500 to $9,000 |
Each layer costs less than the one below it, because a claim has to burn through everything underneath first. Specialty insurers also set a minimum premium for a layer, illustratively $2,500 to $5,000, moving with your trade, your limit, and how much of your work is at height.
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: An excavation contractor in Texas with 14 employees wins a $2,100,000 site work package. The exhibit requires $10,000,000 in umbrella or excess coverage. His umbrella insurer stops at $5,000,000.
What went wrong: The broker keeps the $5,000,000 umbrella, illustratively $13,800 a year, and adds a second $5,000,000 layer for about $6,900, also illustrative. The certificate is rejected. The upper policy does not say it matches the umbrella below it.
What it cost: The upper insurer adds a page making that layer match the umbrella below it, in four business days. The start slips a week, roughly $9,000 in idle crew and equipment, on top of about $20,700 in illustrative premium already in the bid.
The fix: Send the insurance exhibit to your broker before you buy the layers. Ask that every layer match the one below it and protect your general contractor.
Frequently asked questions
Q: Can multiple insurance companies provide the liability limit my contract requires?
Yes, in almost every case. Contracts set a total limit, not a rule that one insurer write all of it. Brokers routinely build $10,000,000 from general liability, an umbrella, and a layer on top.
Q: What is a layered tower?
It is what brokers call a stack of liability policies from several insurers. Each layer pays only after the one below it is used up.
Q: Will my general contractor accept limits from more than one company?
Usually yes, if every layer matches the one below it and every insurer meets the contract's rating rule. Ask your broker to show every layer, with its insurer and limit, in the description box or on a second certificate.
Q: Does every layer have to protect my general contractor too?
Yes, if your contract asks for it above the general liability policy. Most umbrellas protect anyone your general liability protects, but only where a written contract required it, and some cap that party at the limit the contract asked for. Higher layers often need their own page.
Q: Why does the top layer cost less than the bottom one?
Because a claim has to use up every layer beneath it first. The insurer at the top is far less likely to pay, so it charges less per million.
Q: Do I have to pay anything myself before an umbrella pays?
Not on a normal claim. The policy underneath pays first and the umbrella takes over when it is used up. You pay your own share first, often $10,000, only where the umbrella pays first because nothing underneath covers the claim.
