Everything That Matters Happens Where You Can't See It.
Protecting well drillers, crews, and the wells they complete
Well drilling is a trade defined by what lies below the surface. Residential, agricultural, and municipal water wells — and the pumps that serve them — are drilled blind into ground the contractor can't inspect, where a bit can strike a buried utility, breach an aquifer, carry contamination between formations, or hit a formation that yields no usable water at all. The result is a risk profile that pairs subsurface pollution and liability with the loss of a six-figure drill rig. This is water-well work; oil and gas drilling is a separate exposure entirely. A well-drilling business needs coverage built around the subsurface and the rig. This is a specialized corner of contractor insurance built for the trade.
Properly structured coverage protects your crew, your clients, and the water the well is meant to deliver.
The Well Driller's Signature Exposure
The defining well-drilling risk is subsurface uncertainty. Drilling can strike an underground utility, breach or contaminate an aquifer, or open a path that lets surface or formation contamination reach groundwater — exposures the general-liability pollution exclusion is built to deny. Alongside that sits completed-operations and contractual risk: a dry well, a well that fails to yield, or one that goes bad after completion can trigger warranty, re-drill, and contract claims. And the rig itself is a high-value, mobile asset — a drill rig can overturn, be damaged, or be destroyed, taking the contractor's earning capacity with it. Pump and system installation errors add a further completed-operations layer.
Key Risks in Well Drilling Work
Well drilling contractors face exposure related to:
Striking an underground utility or contaminating an aquifer while drilling
A dry, failed, or under-yielding well, or one that goes bad after completion
Drill-rig damage, overturn, or total loss of a high-value mobile asset
Property damage to the site during rig setup and drilling
Pump and water-system installation errors discovered after completion
Rig, height, and crush injuries to the crew
Warranty and contractual exposure on well performance
The subsurface claim — a struck utility or a contaminated aquifer — is the exposure that most defines the trade.
Core Coverages for Well Drilling Contractors
A properly built well-drilling program typically includes:
General Liability with Completed Operations — Covers third-party injury and property damage, including damage to the site and resulting damage from the work, while the "your work" exclusion limits re-drilling the well itself.
Contractors Pollution Liability — Covers aquifer and groundwater contamination, cross-formation migration, and fuel or fluid spills the general-liability pollution exclusion denies.
Inland Marine / Equipment Coverage — Covers high-value drill rigs, pumps, and tooling on the job and in transit — the trade's largest insured asset.
Commercial Auto — Covers rig trucks, support vehicles, and the transit of equipment and materials.
Professional Liability — Protects siting and design responsibility when the contractor advises on well location or depth.
Workers' Compensation — Provides legally required coverage for rig, height, and crush injuries.
Commercial Property — Covers the yard, shop, stored equipment, and parts.
Umbrella / Excess Liability — Adds higher limits above the primary program for pollution and rig-related severity.
What's Commonly Overlooked
Well-drilling programs are most often weakened by:
No pollution coverage for aquifer contamination and cross-formation migration
Rig values under-scheduled or insured below replacement cost
An underground-utility-strike sublimit set too low
No professional liability once the contractor advises on siting or depth
Weak one-call/811 locate documentation, which raises both risk and premium
The gap that hurts most is the absence of pollution coverage for the aquifer and groundwater the drilling can contaminate.
Real-World Claim Examples
A bit strikes an unmarked utility line while drilling, causing damage and outage
Drilling breaches a confining layer and lets contamination reach a drinking-water aquifer
A completed well runs dry or fails to yield, and the client demands a re-drill or refund
A drill rig overturns on an uneven site, destroying the contractor's primary asset
A pump or well-system installation error is discovered after the job is accepted
Any one of these — especially the aquifer-contamination and rig-loss claims — can be severe without the right pollution and equipment coverage.
Regulatory & Safety Context
Well drilling is a licensed trade in nearly every state, governed by state well-driller licensing and well-construction standards that dictate casing, grouting, and sealing to protect groundwater. The EPA's Safe Drinking Water Act and underground-injection control rules govern practices that can affect aquifers, and state environmental and water-resource agencies regulate well permitting and abandonment. Utility one-call/811 "call before you dig" locate laws apply before drilling begins — some states impose near-strict liability for failing to locate — and OSHA governs rig operation, fall protection, and crush hazards on the work site.
Why Proper Placement Matters
Underwriters weigh the mix of residential, agricultural, and municipal work, the depth and geology typically drilled, rig values and age, pollution controls and casing/grouting practices, one-call compliance, and loss history, and they look closely at how the rigs are scheduled and how pollution is structured. The class ranges from admitted markets for straightforward residential drillers to the excess and surplus (E&S) market where rig values are high, geology is difficult, or pollution exposure is significant and terms are negotiated. Placing the account well, and presenting the rig schedule and pollution controls, is what keeps a subsurface claim covered.
Our Approach
At Cory Washington & Co., we insure well drillers around the risks that define the trade — the subsurface strike, the contaminated aquifer, the dry well, and the high-value rig. We structure pollution coverage for groundwater, schedule the rigs to replacement cost, size completed operations to well-performance exposure, and coordinate auto, workers' compensation, and umbrella into one program. We also insure related trades, including general contractors, and carry pollution liability and inland marine for the groundwater and equipment exposures.
Everything that matters in well drilling happens where you can't see it — we build coverage that reaches below the surface with you.

Frequently Asked Questions
How do I get well drilling contractor insurance through Cory Washington & Co.?
Request a quote or contact our team. We start with a short conversation about your operations, analyze your exposures, then negotiate well drilling contractor insurance across multiple carriers that compete for your account and present options with the trade-offs explained. Cory Washington & Co. LLC is licensed in all 50 states.
What does well drilling contractor insurance cost?
It depends on your exposure. Well drilling contractor insurance is priced on factors like your industry, size, prior claims, and the limits and deductibles you select — so two businesses rarely pay the same. We shop your account across competing carriers and present the trade-offs in plain English.
Is well drilling contractor insurance required?
Whether well drilling contractor insurance is strictly required depends on your state, your contracts, and your lenders or clients. Even where it is not mandatory, going without it can leave serious financial gaps. We assess your exposure and any contractual requirements, then structure coverage that meets both.
What if another agency has already declined or non-renewed my coverage?
Difficult, specialty, and previously-declined placements are a core part of our work. We access excess & surplus (E&S) and specialty markets that many generalist agencies cannot, and we explain the trade-offs clearly so you can decide with confidence.
