America has a long history of wooden fences, and a house with a white picket fence is a mainstay of the American dream. Many modern people still love both the practicality and tradition of a wood fence, but wood comes in many types. How do you know which types of wood fences are best for…
Once you’ve made the decision to add or replace a fence, you’re probably ready to have it installed yesterday. Our customers always ask the reasonable question, how long will it take to install my new fence? On average, it takes us a few days to install a fence. We know, that’s a vague answer. But…
At Buzz Custom Fence, we understand the frustration of fence post-splitting, a common issue many homeowners face. We’ve heard this heartbreaking story too many times: Homeowners decide to build a fence themselves, or, worse, they hire a disreputable fence company. The fence is finished, it looks gorgeous, until one day, often in summer, you think…
All over the country, people are surprised by seeing colorful flags stuck in their yard, or sometimes even finding their grass spray-painted. Is this some new holiday nobody told you about? No. It probably means that a neighbor is about to do some digging, or that a utility operator is planning repair and maintenance, or the city’s going to excavate and needs to mark buried lines and piping in the next month.

811 Dig
You’ve probably heard of 811 Dig. This is part of our great national system of keeping track of underground lines and locating utilities. Line owners and utilities must register their underground assets, and anybody planning to excavate must check out their property for matches. The “excavator” category includes swimming pool contractors, landscapers, do-it-yourselfers and yours truly, fence builders, like Buzz Custom Fence.
You might be tempted to blow off calling 811 if you’re only planting a tree or a fence post. It’s not like you’re building an underground bunker. But Texas law requires you to call 811 if you’re digging 16 inches or deeper. So be a good citizen and give them at least 48 hours’ notice.
Utility Flag Color Code
So what does this rainbow of marking flags in your yard mean?
- Red flags – Red is the most common flag. It signifies electric utilities, such as cables and power lines. These mark the power lines that connect to a neighbor’s power grid. Marking these junctions helps avoid a neighborhood-wide power outage.
- White flags – White flags mean excavation. Often you’ll see these set out for a city excavation project. The extent of the white flagged area will give you a sense of how big a project you’re in for.
- Pink flags – These are used as temporary survey markings. As surveyors measure, they mark their work with pink flags. Measure twice, cut once, and use plenty of pink flags. Pink is also used to mark mysteries. If a utility can’t be identified, a worker will pink flag it.
- Yellow flags – Just like yellow caution tape, you want to stand back from yellow flags. These mark gaseous materials, petroleum, steam and other stuff that’s nasty when it gets loose, possibly causing soil contamination or explosions.
- Orange flags – Remember land lines? These get orange flags, as do other communication systems, such as signal or alarm lines, or TV cables. Don’t enrage your neighbor by cutting through that cable just before the big game.
- Blue flags – Blue means water, irrigation or slurry. Usually this is drinking water. Damage this line and you could flood your home or find yourself without drinking water for a few days.
- Purple flags – Purple also marks water, but the kind you don’t want to drink: recycled water from waste water. But it’s good for landscape irrigation.
- Green flags – Green flags mean drain lines and sewers. Cutting this line could release poisonous gasses and flood the neighborhood.
