There is no published price for restoration contractor insurance in Idaho, and any number you see quoted before an underwriter has looked at your work is a guess. What a carrier actually does is build the cost from your specific operation — and for a restoration contractor, the input that moves the number most is not the building you work out of or the trucks you drive. It is how much of your work carries an exposure the standard policy quietly refuses to cover.
That is the part owners find counterintuitive, so it is worth saying first. The very substances an Idaho restoration crew is hired to remove — the smoke and soot a wildfire drives into a structure, mold, and the sewage in a Category 3 water loss — are treated as pollutants under the standard general-liability pollution exclusion. The loss you are most likely to cause while doing your job well is the one your base policy carves out. This guide walks the drivers that decide what an Idaho restoration contractor actually pays.
The pollution line, and the fire that feeds it
This is the driver that sizes the program, and it is the one a generic contractor policy gets wrong. A standard general liability policy answers for the third party hurt on your jobsite and the property you damage by accident — but it carries a pollution exclusion, and an underwriter of restoration risk reads that exclusion against the work you actually do.
The smoke and soot after a fire is the clearest case in Idaho: remove it and later have the odor return, cross-contaminate a clean area, or fail a post-remediation check, and the claim that follows is an environmental claim, answered — if at all — by contractors pollution liability. Mold reads the same way, and so does Category 3 sewage. The underwriting question is never “how big is your crew.” It is: how much of your revenue touches fire, mold, and sewage remediation, and how disciplined is the protocol around it?
Wildfire leads the book here
Few states put fire at the front of the restoration book the way Idaho does. Wildfire is the leading restoration driver, with severe winter and freeze events behind it and hail filling in — a peril set with no single seasonal spike, which is why the book runs steady rather than spiking on one event.
That matters to your premium because fire work carries the deepest pollution exposure of the trade. Smoke and soot remediation is a specialized environmental job, and an operator whose revenue leans on it is underwriting a heavier pollution risk than one who mostly dries out frozen pipes — even though both wear the same company name in Boise or Coeur d’Alene. How much of your book is fire remediation is a first-order input, not a footnote.
Earthquake sits in a separate policy
Idaho is seismically active, and that surprises owners who think of the state as fire-and-freeze country. But earthquake is handled as a separate seismic placement — it is not carried through the pollution, equipment, and comp lines that make up a restoration program.
What earthquake does touch is the work. A seismic event, like a storm or a fire, produces water intrusion, structural damage, and the remediation that follows — and that cleanup flows back into the same mitigation, reconstruction, and pollution exposures your program already prices. The event is placed separately; the restoration work it generates is underwritten the usual way, on the same drivers as everything else in this guide.
No state mold license — guidance, and the contract
Idaho issues no state mold assessment or remediation license. The Department of Health and Welfare provides mold guidance rather than a credential, so mold work is contract-governed.
Where a state license exists, it writes a baseline standard of care an underwriter can lean on when a claim lands. In Idaho there is no such baseline, so the perimeter around a mold claim is your contract, your protocol, and any national certification you carry. That absence is a cost driver: the pollution line and the agreement you sign are doing part of the job a license does in a licensing state.
Trade mix, payroll, and the crew
What you do shapes what you pay, because the phases of restoration are different risk profiles under one company name. Mitigation — including fire cleanup and water extraction — concentrates the pollution and equipment exposures; reconstruction carries the completed-operations tail on a rebuild; contents pack-out puts other people’s property in your care.
Workers compensation then scales with payroll, and the classifications matter as much as the figure — a crew in respirators in a smoke-filled or contaminated structure is not a clerical class. Idaho runs a private, competitive comp market, so the discipline is honest classification and a low injury profile through respirator, confined-space, and fall-protection practice.
The mountain-state drying fleet and the contents you hold
The equipment schedule. Contractors equipment covers the dehumidifiers, air movers, air scrubbers, and generators that deploy from the Treasure Valley out to mountain and rural communities and live on a customer’s loss site for the length of a dry-out — in transit over long hauls, staged where you do not control the premises, and exposed to theft. Where those run behind your own service trucks, commercial auto sizes to the vehicles; here carrier means the insurance company writing your coverage, not a motor carrier hauling freight.
The contents line. Pack out a customer’s furniture, electronics, and documents and hold them at your facility, and those goods are in your care, custody, and control — exactly what the general-liability policy carves out. Bailees coverage answers for them.
The claims economy, limits, and history
Most restoration work arrives insurer-funded — the property owner’s carrier sets the scope you are paid on, and your receivables and program relationships flow from that reality. We describe that economy because it shapes your exposure; we do not advise a property owner on their own claim, and this guide does not either.
Claims history moves pricing more than almost anything else — not just whether you have had losses, but what they say about how the operation runs. And limits and retention are a genuine choice: how much of the small stuff you fund yourself in exchange for a better price on the pollution and excess limit you cannot afford to be short on when a large fire or mold loss lands.

The honest summary
An Idaho restoration contractor is priced on exposure, not on square footage. The wildfires matter, the freeze matters, the seismic country matters — but the thing that moves the number most is how much of your work touches the fire, mold, and sewage the standard policy refuses to cover, and whether your program carries the pollution line that answers for it in a state that licenses none of it.
If you want to see how the coverage itself works rather than what it costs, start with contractors pollution liability — the line this whole conversation is really about — or step back to the restoration contractor insurance program and the full Idaho restoration contractor insurance page. When you are ready for a number built on your real operation, start a quote. And if you test and mitigate radon rather than respond to losses, none of the above is your program: you want the radon mitigation cost guide instead.
