Installing a fence around your property might seem straightforward, but there is one critical step that should never be skipped: calling 811 before any digging begins. This simple phone call can prevent costly damages, serious injuries, and legal troubles. It is not just a recommendation; it is a necessary safety measure that your contractor must follow. Here’s why calling 811 before fence installation is essential.

Understanding What 811 Is and Why It Matters
811 is the national call-before-you-dig number in the United States. When you call 811, your local utility companies are notified to come out and mark the locations of underground utility lines such as gas, water, electric, and telecommunications. This service is free and designed to protect homeowners, contractors, and utility workers.
Underground utility lines are often buried just a few inches below the surface. Without proper marking, digging can accidentally hit these lines, leading to:
Gas leaks or explosions
Electrical shocks or outages
Water main breaks and flooding
Disruption of phone or internet services
Calling 811 ensures that your contractor knows exactly where it is safe to dig, preventing accidents and costly repairs.
Legal Requirements and Liability
Many states have laws requiring homeowners and contractors to call 811 before any excavation work. Ignoring this step can lead to legal consequences, including fines and liability for damages.
If a contractor digs without calling 811 and damages a utility line, they may be held responsible for:
Repair costs
Fines from regulatory agencies
Medical expenses if injuries occur
Delays in the project timeline
By calling 811, your contractor complies with the law and protects both themselves and you from unnecessary risks.
Protecting Your Property and Investment
Fence installation is an investment in your property’s security, privacy, and value. Damaging underground utilities during installation can cause:
Unexpected repair bills that exceed the fence cost
Delays in completing the fence
Damage to landscaping and hardscaping
Safety hazards for your family and neighbors
Calling 811 helps avoid these problems by ensuring the digging is done safely and accurately. It also shows that your contractor is professional and responsible.
How the 811 Process Works
The process is simple and efficient:
Call 811 or submit a request online a few days before the planned fence installation.
Utility companies receive the notification and send locators to mark underground lines with color-coded paint or flags.
Your contractor reviews the markings and plans the digging accordingly.
Fence installation proceeds safely without hitting any utility lines.
This process usually takes 2 to 3 business days, so planning ahead is important.
What to Expect from Your Contractor
A knowledgeable contractor will always:
Inform you about the need to call 811 before digging
Make the call themselves or confirm it has been done
Wait for utility markings before starting work
Respect the markings and avoid digging in those areas
Use hand tools near marked lines if necessary to avoid damage
If your contractor skips this step or seems unaware of 811, it is a red flag. Always choose a contractor who prioritizes safety and follows proper procedures.
Additional Tips for Fence Installation Safety
Always verify that utility lines have been marked before digging.
Use hand tools near marked areas to avoid accidental damage.
Keep a safe distance from marked lines as recommended by utility companies.
Communicate clearly with your contractor about safety procedures.
Keep emergency contact numbers handy in case of an accident.
Summary
Calling 811 before fence installation is not optional. It is a crucial safety step that protects your property, your family, and your investment. It prevents accidents, legal issues, and costly repairs. Make sure your contractor understands this responsibility and follows through. Taking this simple step ensures your fence project goes smoothly and safely.
