Contractor insurance

Insulation contractor insurance

Insulation work is largely invisible once it is finished, which means problems tend to surface as something else entirely: moisture, odour or a callback about comfort. Spray foam in particular changes the insurance conversation significantly.

What the work usually involves

The product you install matters more here than in most trades. Spray foam, blown product and batt work are not underwritten the same way.

  • Batt and roll installation in new construction
  • Blown cellulose and fiberglass in attics
  • Spray polyurethane foam, open and closed cell
  • Rim joist, crawlspace and basement work
  • Air sealing, vapour retarders and baffles
  • Retrofit and weatherization on existing homes
  • Removal of existing or damaged insulation

Risks worth talking through

Spray foam chemistry

Two-component foam is an exothermic chemical reaction performed on site. Off-ratio application, improper lift thickness and inadequate ventilation lead to odour complaints, occupant displacement and, in the worst cases, a house that needs the product removed. Many carriers treat foam as a distinct exposure from other insulation work.

Re-entry and occupancy

Telling a homeowner when it is safe to return is a judgement with real consequences. Disputes in this trade frequently center on what the occupant was told and when.

Fire and ignition

Combustible foam generally requires a thermal barrier, and heat sources, recessed lighting and flues all interact with insulation. Work near ignition sources deserves specific attention.

Moisture and condensation

Insulation changes where the dew point sits in an assembly. Get it wrong and the result is condensation, rot or mold inside a wall or roof deck, discovered long after the job closed.

Attics, crawlspaces and confined work

Crews work in tight, hot or cold spaces with limited egress, around ceiling joists that are not walking surfaces. Falls through ceilings are a routine claim.

Removing what is already there

Tear-out of contaminated or damaged insulation brings disposal questions and possible exposure to materials in older homes.

Coverage areas to review

General liability

General liability may help address claims alleging bodily injury or damage to someone else's property arising from your operations. Coverage depends on the policy terms and exclusions. If you install spray foam, expect that to be underwritten specifically, and expect questions about training, equipment calibration and ventilation practice. Pollution-related exclusions can interact with foam and with removal work, so the wording deserves an actual review.

Workers compensation

If you have employees, the exposures are falls through ceilings, heat stress in attics, respiratory exposure and contact with chemicals. Whether crews apply foam, and whether they perform removal work, should both be stated clearly.

Commercial auto

Box trucks and trailers carrying rig equipment, blowing machines and product. Foam rigs in particular represent significant value inside a vehicle, which affects both the auto and the equipment conversation.

Rigs, machines and product

Spray rigs, proportioners, hoses, blowing machines and compressors carry high values and often live permanently in a truck or trailer. Whether that equipment is covered in the vehicle, at a jobsite and at your shop is worth confirming separately, as is product inventory in storage.

This page is general information, not legal, safety or coverage advice. What a policy actually covers depends on your business operations and on the policy, carrier, terms, conditions, limits and exclusions that apply. Nothing here confirms eligibility or guarantees that any coverage is available to you.

What to have ready for a review

  • Approximate split between batt, blown and spray foam work
  • If you spray foam: open cell, closed cell, or both
  • New construction versus retrofit on occupied homes
  • Your ventilation and re-entry practice for foam jobs
  • Whether you perform removal or remediation of existing insulation
  • Rig and equipment values, and where they are stored
  • Employee count and payroll
  • Any claims or incidents from the last several years

Questions we hear

Does spray foam really change how I get quoted?

Yes, noticeably. Foam is a chemical process performed inside someone's home, and the claims that go badly tend to go very badly, including cases where occupants cannot return. Carriers underwrite it as its own exposure, which is why it should be disclosed clearly rather than described generally as insulation.

A homeowner says the house smells months after we sprayed. What now?

It is usually worth telling us early, even before you know whether it is your product. Odour complaints in foam work can escalate into displacement and remediation claims, and the early record of what was applied, at what ratio and under what conditions usually determines how the matter resolves.

We found mold in a wall we insulated two years ago. Is that covered?

It depends heavily on the policy. Mold and moisture exclusions are common, and there is usually a question about whether the issue is your workmanship or a building condition you did not create. This is worth reviewing in your actual policy rather than relying on a general answer.
