Overgrown Trees Touching Power Lines
in Charleston, SC
In Charleston, trees grow fast. The heat and humidity from May through September push live oaks, sweetgums, and Bradford pears into power lines before most homeowners notice. Once a branch is sitting on a line, a single thunderstorm can snap it and knock out power — or start a fire.
Quick Answer
Branches growing into power lines is one of the most common calls we get in Charleston, especially after a wet spring when trees put on a lot of growth fast. The fix is cutting branches back far enough that they stay clear even when the wind picks up. That work has to be done carefully and in coordination with the utility if the lines are live. Call (854) 205-3541 the moment you see contact — don't wait for a storm to make it worse.
Telltale Signs
Warning Signs to Watch For
- Branches visibly resting on or wrapped around power lines
- Buzzing or crackling sound near the tree during humid weather
- Flickering lights inside the house during wind
- Scorch marks or blackened bark where a branch meets a line
- Utility company left a notice on your door about line clearance
- Tree leaning noticeably toward the utility pole
Root Causes
What Causes Overgrown Trees Touching Power Lines?
Fast summer canopy growth
Charleston gets roughly 52 inches of rain a year, most of it dumped in heavy bursts from May through August. That moisture, combined with long stretches of heat, pushes canopy growth several feet in a single season — fast enough to close a gap that looked safe last fall.
The Fix
Clearance Pruning
A trimmer removes the branches that are in or near the lines and shapes the canopy so it grows away from the utility corridor. This needs to happen every one to three years depending on the tree species.
Tree planted too close at build
Older neighborhoods like Avondale and North Charleston have trees that were planted decades ago, before anyone measured how wide they would get. A tree that starts six feet from a pole will eventually reach it — there is no trimming schedule that fixes a bad planting location forever.
The Fix
Structural Pruning or Removal
If the tree can be shaped to direct growth away from the lines long-term, we do that. If the trunk is already too close and the problem will keep coming back every season, removal is the honest answer.
