After years of writing policies for fencing contractors, the same handful of gaps show up again and again — usually not because a contractor was careless, but because a generic policy from a generalist agent simply wasn't built around how fencing work actually happens. Here are the five most common mistakes, and how to fix each one.
Mistake #1: Assuming General Liability Covers Everything
This is by far the most common misunderstanding. General liability is the foundation of a fencing insurance program, but it's specifically third-party bodily injury and property damage coverage — it does not cover your own tools, your own vehicles, your own materials, or your employees' injuries.
The fix: Think of general liability as one piece of a program, not the whole program. A complete fencing operation typically also needs workers compensation (once you have employees), tools & equipment coverage for your augers and power tools, commercial auto for trucks and trailers, and — because fences remain a liability exposure for years after installation — solid completed operations coverage layered on top of GL.
Mistake #2: Leaving Job-Site Materials and Equipment Uninsured
Fencing materials are bulky, hard to secure, and often delivered or staged days before a crew starts work — chain-link rolls, ornamental panels, and cedar pickets left on an open job site are an easy target, and augers and post drivers left overnight on a multi-day install are exactly what theft is opportunistic about. Neither general liability nor a personal auto policy covers this.
The fix: Tools & equipment insurance (inland marine) covers your mobile equipment against theft and damage wherever your crew takes it. An installation floater covers the actual fence materials and hardware while they're staged or in transit, before they become a permanent part of the finished structure. Together, these close the gap between "materials purchased" and "materials permanently installed" — exactly the window fencing contractors are most exposed in.
Mistake #3: Using Uninsured Subcontractors Without a Paper Trail
Bringing on a subcontractor for overflow work or a specialty like welding is common in fencing, but if that sub doesn't carry their own active insurance — or you don't collect and keep a certificate proving it — their work can become your liability exposure with no coverage behind it. This is one of the fastest ways to see a claim denied or a renewal premium spike, because it signals uncontrolled risk to an underwriter.
The fix: Before any subcontractor sets foot on a job site, get a current certificate of insurance from them and, where the contract allows, request additional-insured status naming your business. Keep these on file for every job. If a sub can't produce proof of coverage, treat that as a real decision point, not a formality to skip.
Mistake #4: Skipping Completed Operations Coverage — or Not Realizing It's Different From GL
Most trades finish a job and their liability exposure drops off fairly quickly. A fence is different: it keeps doing its job — holding back wind load, containing pets and kids, marking a property line — for years after you've left the site, which means claims can surface long after the work is done. A fence panel that comes loose in a storm, a gate that fails and injures someone, a boundary dispute blaming your installation for water drainage onto a neighbor's property — all of these can trigger a completed operations claim well after the invoice was paid.
The fix: Confirm your general liability policy's completed operations coverage is structured with fencing's long-tail exposure in mind, and make sure that coverage doesn't quietly lapse if you switch carriers or let a policy lapse between renewals — continuous coverage matters because you don't get to choose when a claim from three years ago gets filed. Simple documentation habits help too: photos of finished work, post-depth records, and a signed completion form from the customer all make a future claim far easier to defend.
Mistake #5: Underinsuring for the Jobs You're Trying to Win
A contractor bidding only small residential jobs can often get by on standard $1M/$2M general liability limits. But the moment you start chasing larger commercial contracts, HOA-community developments, or municipal right-of-way work, many of those contracts contractually require $2M–$5M in combined liability limits before you're even eligible to bid — and showing up without them doesn't just risk a claim, it can cost you the job outright.
The fix: If you're actively trying to grow into larger commercial or municipal work, price out a commercial umbrella policy alongside your general liability now, rather than scrambling to add it after you've already won a bid that requires it. It's one of the more cost-effective ways to extend your liability limits, since it only pays after your primary policies are exhausted.
The Common Thread
Every mistake on this list comes down to the same root cause: treating fencing insurance like a generic contractor policy instead of building a program around how a fencing business actually operates — materials staged on open job sites, tools that travel between locations, subcontractors brought in for overflow work, and a finished product that keeps creating liability exposure long after the invoice is paid.
