Digging fence holes in your yard needs to be done with certain precautions, namely avoiding underground wires. Otherwise you can do more harm than good, damaging certain systems in your home and putting your safety at risk.
Some utilities are marked, whereas others are not. At any rate, electrical service wires, internet wires, cable TV, telephone service wires and natural gas supply pipes are usually marked. However, lawn irrigation systems, security systems, landscape lighting systems and underground cables running to pools are typically not marked. The question is: can you find the unmarked underground wires by yourself?
You should definitely be able to do that. However, it is more than recommended to check with your local utility provider, just to be sure. The thing is, when a property is sold to another person, the exact location of utility lines is rarely communicated to the new owner of this property. Responsible Thornton fencing companies will engage local utility providers to mark underground cable paths prior to fence and gate installation.
The depth requirements for underground wires may vary a lot, depending on the exact climate of the area you are located in. Thus, in areas with colder winters, the recommended depth is below the frost line, whereas in warmer climates, the wires may be buried at a shallower depth. So it is always best to get informed before starting to dig your fence holes.
