Oakland, NJ · ISA Certified Arborist #1040A

Live Oak Tree Service: certified arborist tree care for Northern Bergen County

Family-operated for over 20 years. Derek Biernacki's crews take down what has to go, prune what should stay to the ANSI A300 standard, and leave the yard cleaner than they found it.

How we prune

No spurs in a tree we're keeping.

Climbing spurs punch holes through living bark, so Live Oak's climbers only strap them on for a removal. A tree that stays gets climbed on rope and cut to the ANSI A300 pruning standard: crown reduction, elevation and balancing, dead and diseased wood out from three-quarters of an inch up, and young trees shaped early so they never need the heavy cuts later.

One customer put it this way: “very careful to cut the trees in an artistic way.”

Live Oak is family-operated and locally owned, so the trucks you see on your street go home to Oakland at night. Call for a visit and an arborist comes to look at the tree before anyone talks about cutting it.

Before you call

What people ask the arborist

Yes. Owner Derek Biernacki is an ISA Certified Arborist, #1040A. The company also holds New Jersey Tree Care Company license #NJTC768569 and Licensed Tree Care Operator #297, and those numbers are painted on the trucks.

No. Spurs wound the bark of a living tree, so the crew only uses them on removals. Pruning and trimming follow the ANSI A300 pruning standards.

Yes. Removals include stump grinding and a full cleanup of the debris once the tree is down, whether the job is done from the bucket truck or by a climbing crew.

Call (201) 337-3616. The crew evaluates the damaged tree, removes what has come down or is hung up, and cleans up afterwards. We can also look at the trees still standing and talk about keeping the next storm from doing the same damage.
