Decide what the trim is for
A good trim starts with a reason, and the reason decides which branches go. Around here the usual ones are:
- Getting limbs off the roof and carport. A limb lying on the shingles rubs them whenever the wind moves it.
- Taking out dead, cracked or hanging wood. Dead or split limbs over a roof, the driveway or a play area are worth removing before they fall.
- Clearing the service wire. On Entergy's system, keeping branches off the wire between the pole and the house is the owner's job (more below).
- Raising limbs over the driveway or the street. Trucks, mail carriers and school buses need the room.
- Thinning a crowded young tree. Spacing out the main branches while a tree is young saves big cuts later.
Say which of these you want when you ask for a price, and ask the crew to point out which limbs they plan to cut before they start.
Live oaks over the house
Live oak earns its reputation. University of Florida researchers studying hurricane damage put live oak in their "Highest Wind Resistance" group for the Southeastern Coastal Plain. LSU AgCenter horticulturist Dan Gill calls it "one of our most hurricane resistant native trees," and LSU's Allen Owings wrote that it "was one of the major tree species that survived the wind and flooding of Hurricane Katrina" (all checked Nov 11, 2026).
The catch is size. Owings wrote that live oaks "need to be planted on 90-foot centers," which says a lot about how wide one gets. A live oak planted near a house will, in time, put its long, low limbs on the roof. The Live Oak Society, a registry of more than 7,500 notable live oaks, takes members with a girth of 8 feet or more and classes girths over 16 feet as centenarians (LSU AgCenter, checked Nov 11, 2026).
So the usual job is reduction, not removal: shorten or remove the limbs that reach the roof, cut back to a branch or the trunk rather than leaving stubs, and leave the crown balanced. Remember that "highest" isn't storm-proof. The February 7, 2017 EF-3 tornado near Watson snapped numerous hardwood trunks, "including a large live oak," according to the Weather Service survey (checked Nov 11, 2026).
Denham Springs' landscape ordinance lists live oak in its native-tree table at 18 inches in diameter. That table applies within the city's permits for clearing an acre or more and for development, not to pruning a tree in your yard (city's posted ordinance, checked Nov 11, 2026).
Water oaks and other brittle wood
Water oak behaves very differently. LSU's horticulture plant page says it has "relatively weak wood compared to other oaks that causes substantial branch breakage and decay." LSU AgCenter's "Water Oak Warning" quotes Clemson Extension writers who say it "is more weak-wooded than most oaks and prone to damage from wind, snow and ice," and its author adds from site visits that "Large water oaks tend to have broken branches and obvious cavities" (checked Nov 12, 2026).
For a younger water oak, the Clemson advice the same article passes along is about trimming: train the tree to a central trunk, keep the main branches spaced 2 feet or more apart, and prune regularly so you never need a big cut, since large pruning wounds can let decay in. On a big old one with cavities, trimming may only buy time; the water oak guide covers when removal makes more sense.
The University of Florida list puts several other common trees here in its "Lowest Wind Resistance" group with water oak: laurel oak, pecan, Chinese tallow and Bradford or Callery pear (checked Nov 11, 2026). Expect more broken limbs from those after a storm.
Branches near power lines
DEMCO and Entergy Louisiana both serve parts of Livingston Parish, and your bill tells you which is yours. Both trim along their lines on a schedule, but neither covers everything.
| DEMCO | Entergy Louisiana | |
|---|---|---|
| Trimming cycle | Clearances kept "over the length of the cycle, which is six (6) years" | Trims far enough back to keep trees from growing into the line, often with directional pruning |
| Trees in the right-of-way | Removal recommended when the main stem stands inside the right-of-way | Trees posing a risk inside or outside the right-of-way may be cut down |
| The wire to your house | Not addressed in its manual; call to ask | "We DO NOT trim service lines"; the owner's job, and the line can be disconnected temporarily for the work |
| Debris | Cut up and left on site | Not cleaned up after storm damage, customer-requested trims or hazard trees |
| To ask about a tree | 1-844-693-3626 or ROW@DEMCO.org; right-of-way department 225-262-3097 | 800-368-3749; each concern gets an inspection, with a 10-working-day commitment |

The law draws a hard line. Louisiana's Overhead Power Line Safety Act bars work that could bring a person, tool or equipment within 10 feet of a line over 600 volts until the line's owner has been given at least 48 hours' notice, weekends and holidays not counted, and the two sides have agreed on safety measures (La. R.S. 45:141 to 45:143, checked Nov 11, 2026). Federal OSHA rules use the same 10-foot distance for unqualified workers in elevated positions near lines of 50,000 volts or less to ground. DEMCO's own advice: "avoid touching a tree that is growing into or near one."
Limbs over the street and the ditch
The grassy strip with the roadside ditch often belongs to the city, the parish or the state, and so may the tree in it.
- Denham Springs. The city's ordinance makes it unlawful, unless the landscape review coordinator authorizes it, "to cut, trim, spray, remove" trees on public property. If the coordinator doesn't act on a permit within ten working days, the permit is issued automatically (city's posted ordinance, checked Nov 11, 2026). The Street Department is at (225) 667-8352.
- Parish roads. Livingston Parish Public Works requires the Director's approval to remove a tree in a right-of-way (checked Nov 11, 2026). Ask Public Works before cutting limbs from one, too.
- State highways. DOTD's vegetation maintenance permit covers trimming and removal in the state right-of-way. The owner or lessee of the property signs it, and the contractor can't get it on your behalf. Work within 20 feet of the travel lane needs DOTD's written authorization, and traffic control follows the MUTCD, the national manual for traffic control devices. Livingston Parish falls under DOTD District 62, whose permit office in Hammond is at 800-545-9280 (checked Nov 11, 2026).
Branches from next door
Louisiana Civil Code article 688 says a landowner "has the right to demand that the branches or roots of a neighbor's trees, bushes, or plants, that extend over or into his property be trimmed at the expense of the neighbor," but not if they "do not interfere with the enjoyment of his property" (checked Nov 11, 2026). The article gives a right to demand the trimming; it doesn't say you may cut the neighbor's tree yourself. Talk to the neighbor first, and get the agreement on who's trimming in writing if money is involved.
The brush afterward
A trimmed live oak produces a surprising amount of brush. In Denham Springs, Waste Pro takes household branches no longer than 6 feet but not debris a contractor generates. In Walker, Waste Management takes tied bundles up to 4 feet long but won't collect tree-service debris, and the city can take action against both resident and contractor for setting it out (both checked Nov 11, 2026). Make chipping and hauling part of the price.
Published trimming prices
| Source | What it lists | Range |
|---|---|---|
| HomeGuide | Average trim, per tree | $400 – $900 |
| HomeGuide | Tree up to 30 ft | $250 – $700 |
| HomeGuide | Tree 30 to 60 ft | $600 – $1,200 |
| HomeGuide | Tree over 60 ft | $1,000 – $2,500+ |
| HomeGuide | Climbing and cutting, per hour | $50 – $125 |
| Thumbtack | National average trimming range | $270 – $450 |
HomeGuide's low end is about $80 for a small tree, and it notes that "Emergency trimming after storms almost always costs more than planned maintenance." All figures are national and were checked Nov 11, 2026; HomeGuide shows no update date. A trim on a wide live oak over a roof, with rope work and hauling, can land well above a simple trim on an open-grown tree, which is why the contractor's written price is the number to use. More on the tree work prices page.
Trimming questions answered
Should I take the live oak down because it's over the house?
Usually not if it's sound. Live oak rates highest for wind resistance in the University of Florida research, so cutting back the limbs on the roof is the common answer. Rot, a crack in the trunk or major root damage changes that.
Will Entergy clear the branches off the line to my house?
No. Entergy says it does not trim service lines and that the line from the house to the first pole is the owner's responsibility, but it can disconnect the line temporarily so the work can be done (checked Nov 11, 2026). If DEMCO serves you, call DEMCO to ask how it handles that line.
Can I trim the neighbor's branches hanging over my yard?
Civil Code article 688 lets you demand that the neighbor trim them at the neighbor's expense if they interfere with the use of your property. Start with a conversation.
How much should come off at once?
Ask the contractor to explain each cut. Regular, smaller cuts are better than one big one; the pruning advice in LSU AgCenter's water oak article warns that large pruning wounds can start decay.
Trimming requests from this site are handed to one independent contractor working in Livingston Parish. The site has no crews of its own.
