Structural Pruning That Improves Health, Safety, and Longevity
ANSI A300-standard pruning by ISA-certified arborists — not just a crew with chainsaws.
Bad Pruning Kills Trees. Good Pruning Extends Them.
Lion's tailing — stripping interior branches to weight the tips — causes trees to become top-heavy and wind-sail prone. Topping creates large wounds that never close properly, leading to decay, structural failure, and premature death. Flush cuts remove the branch collar, the tree's natural healing mechanism.
ISA-certified arborists follow ANSI A300 pruning standards because these techniques exist for a reason — they're what the science supports. Our goal is always to improve the tree, not just to make it look different.
Types of Pruning We Perform
Crown Cleaning
Selective removal of dead, dying, diseased, and crossing branches to improve structural integrity and reduce pest habitat.
Structural Pruning
Early-stage training for young trees to establish strong branch architecture and reduce future defect risk.
Crown Raising
Removal of lower limbs to provide clearance for structures, pedestrians, vehicles, or sight lines.
Crown Reduction
Reducing the overall size of the canopy while maintaining natural form — not topping, never topping.
Managing multiple properties? We offer scheduled pruning cycles as part of our 12-month maintenance agreements.

Working with Peak was a great experience. They were professional, reliable and did a fantastic job. They took great care with the work, and everything was cleaned up nicely afterwards. I would highly recommend them to anyone looking for quality tree trimming services.

Absolutely the best my tree has ever looked! I've had my tree trimmed 4 times over the years and this was the best company I've worked with. They were reasonably priced and clean. They took my concerns seriously and understood that my main priority was my tree's health. I have an 80 foot oak tree and really want it to be storm proof, I'm very happy to say I think it is.
