Claims
From the first letter to a closed file — what the claims process looks like for a retaining wall failure, water intrusion behind stonework, or a crack that surfaces months after the job is done.
A masonry claim doesn't usually start with a phone call from the person you built the wall for. More often it's a letter from a homeowner's attorney, a notice from a property manager's insurance carrier, or a GC forwarding a complaint from the project owner months after your crew has moved on to three other jobs. Whoever it comes from, the clock on your response starts the moment you're notified — not the moment you decide the claim has merit.
Say a retaining wall you built two years ago starts leaning and the property owner calls it in. Your carrier assigns an adjuster, who typically brings in a structural engineer to determine whether the failure traces back to your workmanship, a drainage design flaw that wasn't yours to fix, or ordinary soil movement nobody could have prevented. That engineering report becomes the center of everything that follows — it's what determines whether the carrier defends you outright, negotiates a partial settlement, or contests the claim.
Water intrusion claims tend to get contentious fast because the causation question usually involves more than one trade. Was it your mortar joints, the waterproofing membrane installed by someone else, or flashing detail that fell between your scope and the GC's? Carriers on both sides often end up pointing at each other's insured, which is exactly why clear certificates and scope documentation from the original job matter more than most masons realize until they're the ones defending a claim.
Masonry has a habit of hiding its problems. A structural crack might not surface until a renovation years later exposes it, and by then the job that caused it may be long forgotten on your end. The moment you're notified of a claim like this — even an informal one — is the moment to report it to your carrier, not after you've decided internally whether you think you're at fault. Reporting late, or trying to informally resolve it yourself first, can complicate coverage.
Once a claim is reported, your carrier typically assigns an adjuster to investigate, and if it looks likely to involve legal action, retains defense counsel on your behalf — a benefit that applies whether or not the claim ultimately has merit. They handle the back-and-forth with the claimant's attorney, negotiate toward settlement where appropriate, and make the call on whether to litigate. Your GL policy is what's paying for all of this, which is part of why the cost of coverage looks small next to what an uninsured claim actually costs to defend.
Report the claim to your carrier immediately, even if you think it's baseless — waiting to see if it goes away is the most common mistake masons make. Document the site as you found it before making any repairs, since altering conditions can complicate the engineering investigation. And avoid admitting fault or offering to fix it out of pocket before your carrier weighs in; a well-intentioned goodwill gesture can sometimes work against you later.

FAQ
It varies widely — a straightforward claim with clear causation might settle in a few months, while one involving disputed engineering findings or multiple trades pointing at each other can take a year or more. Your carrier handles the timeline; your main job is reporting promptly and staying responsive to requests for information.
If the claim falls within your policy's coverage and limits, your carrier handles the defense and any settlement or judgment up to those limits. You may face out-of-pocket costs if the claim exceeds your limits or falls outside what your policy covers, which is one reason limits matter more as your job volume grows.
This is common, and it's exactly what the engineering investigation is meant to sort out. Liability can end up split between multiple parties — your mason, the engineer, the GC — based on what the investigation actually finds, rather than an all-or-nothing outcome.
No — making repairs before the site has been documented and investigated can complicate determining what actually caused the failure, and can sometimes be read as an admission of fault. Report it to your carrier first and let the investigation happen before anything gets touched.
Not automatically. Carriers generally look at claim frequency and outcomes over time rather than penalizing a single reported claim, especially one where you're ultimately found not at fault. Failing to report a claim promptly is a bigger risk to your standing than reporting one that gets resolved in your favor.
