Overview
A structural failure claim arising years after completion raises a common insurance question: which liability policy must be notified and which must respond? Insurers and courts often look to when the damage "occurred" and whether harm was continuous, intermittent, or discrete.
Many cases involve overlapping coverage and defense obligations across successive policies. Preparing an organized notice and documenting the timeline are the first practical steps for a contractor or design firm facing such a claim.
Key takeaways
- Notify all potentially relevant liability insurers promptly — not only your current carrier.
- Court decisions sometimes apply multiple policies when damage is continuous (a "triple trigger" or similar result).
- Record dates, inspections, and communications; insurers will want the construction and damage timeline.
How it works
General liability policies typically cover bodily injury or property damage that "occurs" during the policy period, but courts differ on what constitutes occurrence for progressive or latent damage.
Some jurisdictions treat the date of first manifestation, the date of negligent act, or the date of actual collapse as the trigger for coverage — and other jurisdictions may apply multiple triggers when damage is ongoing.
To understand how your situation might be handled, it helps to review coverage language and consult a broker or coverage attorney early in the process.
What it may cover (and what it may not)
Liability policies often cover repair costs and third-party claims for property damage and loss of use, subject to policy limits, exclusions, and any aggregation rules that apply.
Policies commonly exclude faulty workmanship as a completed operations issue or treat it under a contractors' professional or workmanship exclusion, so coverage can depend on the specific policy wording and cause of the failure.
When a claim alleges progressive damage, multiple policies may be asked to defend and contribute; for practical guidance on these triggers and coverage analysis, see Understanding Coverage Triggers and Liability Insurance.
Common mistakes to avoid
Don’t delay notice to insurers. Late notification can jeopardize defense and indemnity even if coverage would otherwise exist.
Avoid assuming only the carrier in force at the time of collapse is relevant; past carriers may have obligations if damage began earlier and continued.
Don’t discard records from the job — maintenance logs, inspection reports, change orders, and correspondence can be decisive in allocating responsibility and timing.
Questions to ask an agent
Ask which policies may be implicated given a timeline of initial defects, subsequent observations, and the date of collapse.
Request specifics about completed operations coverage, any workmanship exclusions, and how successive carriers coordinate defense and indemnity.
Discuss whether additional protective products, such as contractors' completed operations or professional liability, would have helped in a similar claim.

Next steps
Immediately assemble a chronological file of project documents, inspection notes, and any repair history, and send prompt written notice to all insurers that might be implicated.
Coordinate with your legal counsel and coverage representatives to preserve rights and begin the coverage dialogue while facts are fresh.
If you need help initiating insurer notice or would like a tailored review of your policies, consider ask an agent to review your situation and next steps.
Frequently Asked Questions
Do I have to notify my previous insurance companies about a claim?
Yes — notify any carrier that may have been in effect during the period when damage first occurred or progressively worsened.
Will multiple policies ever share responsibility for a single claim?
Courts sometimes apply multiple policies when damage is continuous, and insurers may be asked to defend and contribute under those circumstances.
What documents should I collect immediately after getting a notice of collapse?
Gather contracts, change orders, inspection and maintenance reports, job photos, and any communications that show when defects were noticed.
Can workmanship exclusions eliminate coverage for repair costs?
Possibly — exclusions and policy definitions vary, so coverage depends on the exact policy language and the underlying cause of the damage.
