DIY or Hire? When to Call in a Private Locator to Stay Safe

If you’re gearing up for a new project that involves digging—maybe you’re installing a fence, setting up an outdoor kitchen, or planting some trees—one of the big decisions is whether to locate utilities on your own or call in a professional. It’s easy to think that DIY locating will save time and money, especially if you’re only going down a couple of feet. But even a simple misstep can lead to hitting a line, turning your project into a costly (and sometimes dangerous) surprise.

I remember when a friend of mine was digging a garden bed. He figured he’d call 811 to get the major lines marked and handle the rest himself. But as he dug, he hit an unmarked irrigation line that ended up flooding his yard. It stalled his project, led to extra costs, and left him wishing he’d called in a private locator.

The question of whether to DIY or hire a professional depends on a few key factors. In this article, we’ll cover when DIY is sufficient, the risks to consider, and when calling in a private locator is essential for a safe, efficient project.

DIY Utility Locating: When It Might Be Enough

For small, shallow projects, DIY utility locating can be practical, especially if you’re just scratching the surface. Planting flowers, installing a mailbox, or laying a shallow walkway typically doesn’t pose much risk of striking a utility.

Simple Projects at Shallow Depths

If you’re digging less than 6-8 inches, there’s a lower chance of hitting critical lines—although, even shallow projects should be done carefully. Calling 811 is a good starting point, as it covers public utilities, but it won’t cover everything.

Using Public Locates for Public Utilities

Public utility services like 811 mark the utilities they own, such as gas, electric, water, and sewer lines. However, their responsibility usually ends at the property boundary or utility meter, which means anything installed by a previous owner or anything on the private side won’t be covered.

Tools Needed for Basic DIY Locates

Some DIYers rely on basic tools like a hand-held metal detector, but keep in mind that metal detectors only detect metallic lines and may miss things like PVC pipes or plastic irrigation lines. If your project is simple and shallow, DIY locating with some basic precautions can work. But for anything larger or deeper, it’s time to consider professional help.

When DIY Locating Falls Short: Risks to Consider

DIY locating can save time, but there are limits to how much a homeowner or contractor can safely do on their own. Without the right tools, DIY methods may leave some utilities undetected.

Lack of Professional-Grade Tools

DIYers often use simple tools, but these have limitations. For example, many irrigation pipes and electrical conduits are non-metallic, making them invisible to standard metal detectors. Without professional tools like ground-penetrating radar (GPR) or electromagnetic locators, you risk missing key utilities.

Hidden Utilities and Private Lines

Private lines, like those feeding pools, landscape lighting, or outdoor kitchens, are often added after a property is built and are not marked by 811. Missing these private utilities is one of the biggest DIY pitfalls, as they won’t show up without the right equipment or expertise.

Safety and Liability Concerns

Accidentally hitting a gas line or electrical cable can create serious safety hazards, and if you hit a line on the private side of the property, you’re financially responsible for repairs. Beyond the repair costs, some lines—like gas—pose real safety risks that can be best handled by a professional.

Key Times to Call in a Private Locator

Knowing when to bring in a private locator can save you from unnecessary headaches and ensure your project goes smoothly. Here’s when calling a professional is essential:

Larger or More Complex Projects

For projects like installing pools, adding outdoor kitchens, or constructing sheds, hiring a private locator is worth the investment. Complex projects often go beyond shallow digging and are more likely to hit something critical.

Older or Newly Purchased Properties

Older properties or recently bought homes may have undocumented utilities that previous owners added. Calling a private locator is an excellent way to identify any hidden lines before starting your project.

When Digging Deeper than a Few Inches

As soon as your project involves digging deeper than a few inches, you’re more likely to encounter underground utilities. Hiring a professional locator ensures you know what lies below the surface and protects against costly repairs or safety hazards.

Benefits of Hiring a Private Locator

Hiring a private locator isn’t just about safety—it’s also a smart financial choice for larger projects. Here’s why:

Access to Advanced Equipment

Private locators use GPR, electromagnetic locators, and other advanced equipment to detect both metallic and non-metallic lines at various depths. These tools can locate utilities that are impossible to find with DIY tools, giving you a complete picture of what’s below.

Detailed Utility Mapping

When you hire a private locator, you’ll often receive a detailed utility map showing exactly where each line is located. This map can guide you or your contractor as you dig, ensuring no lines are hit and giving you the peace of mind that the site is safe.

Peace of Mind and Cost Savings

Professional locating may seem like an added cost, but it’s far cheaper than repairing a damaged line or paying for an emergency crew if you hit a gas or electric line. Calling in a private locator is an investment in a smooth, hassle-free project.

How to Choose a Reputable Private Locator

If you’re considering hiring a private locator, choosing the right one makes a difference. Here are a few things to look for:

Certification and Experience

A certified locator will have the training, tools, and knowledge needed to handle residential and commercial properties. Look for companies certified by organizations like the National Utility Locating Contractors Association (NULCA).

Check Their Equipment and Methods

Ask about the equipment they use—look for services with GPR and electromagnetic locating capabilities, which ensure comprehensive detection. If you’re dealing with a larger or more complex project, make sure they have the right tools to do the job.

Read Reviews and Ask for References

Check online reviews or request references from past clients. Reliable companies will be happy to provide proof of their work quality and experience, which will help you find a service you can trust.

DIY vs. Hire? Know When to Call a Professional for Safety’s Sake

DIY utility locating can work for small, shallow projects, but for most projects, the expertise and equipment of a private locator are invaluable. Taking the extra step to hire a professional reduces the risk of unexpected surprises, protects your budget, and ensures everyone stays safe.

Before you start digging, consider the benefits of hiring a private locator. For a small upfront cost, you’ll gain peace of mind, protect your property, and keep your project on track. When it comes to utility locating, knowing when to call in a pro is the key to a safe, successful project.
