Sin Jac Electric

As the weather warms up and yard projects start rolling, here’s a friendly reminder from Xcel Energy and your neighborhood electrician: Call 811 before you dig!

Whether you're adding power to a shed, gazebo, garage, running new underground lines, digging fence posts or a new garden area: it’s important to know what’s below before you start.

Hitting an underground line can be dangerous, costly, and cause unexpected outages. A quick call to 811 will have your utility lines marked so you can dig safely and with confidence. It’s free, easy, and gives you peace of mind.

We’re always happy to help with planning safe electrical installations—reach out if you have questions.
