Tree Pruning & Tree Trimming

Large Tree Pruning Is Our Specialty

Have you been looking online for “tree pruner Pacific Northwest”? You’ve found what you’re looking for. We work on more than 170 species of large trees found in the Pacific Northwest area.

Our ISA-Certified Arborists® specialize in tree trimming and pruning. Without regular inspection, care, and maintenance, tree branches and hedges can grow out of control, thanks to the Pacific Northwest’s rainy climate that trees love! Tree pruning and trimming from the certified arborists at Drendel’s Tree Service can help your trees stay safe, healthy, and beautiful.

Benefits of Tree Trimming & Pruning

As certified Portland arborists, we love trees! Nothing makes us more sad than seeing a large, beautiful tree become damaged or diseased just because it wasn’t trimmed or pruned properly.

When we prune and trim a large tree, you’ll see benefits like:


Low hanging branches and limbs can scratch cars, damage your roof, or fall and hurt someone walking underneath.


Removing the excess branches and limbs can allow more sunlight into your home and yard. Your tree will look better, too!


Overgrown trees and hedges can give prowlers a place to hide. Trimming trees can let you see out of your windows more easily, too.

Tree Health

Damaged branches can lead to serious tree health issues. Nip problems in the bud. Your trees will thank you!

Our Tree Pruning & Trimming Specialties

Wind Thinning

If your trees are exposed to strong winds, wind thinning can help protect them.

Strategically removing branches allows larger trees to bend and move freely without damaging the trunk and roots.

Pruning & Trimming

Our standard Portland tree trimming and pruning service removes damaged branches and helps your trees stay healthy. You’ll love the results!

Ornamental Pruning

Ornamental pruning can help smaller trees stay healthy and can create a natural piece of art in your Portland landscape.


Lacing a deciduous trees helps thin the canopy, improving air flow and allowing more sun to shine through. It’s also great for the big trees in your Portland yard.

Raising & Balancing

A tree pruner and trimmer in Portland can remove low-hanging branches and help make trees safer and look more balanced.


Dead branches don’t just look bad, they’re unsafe, too! By removing dead or dying branches, our Portland tree trimmers can make your trees safer and healthier.

Crown Reduction

This process requires removing the largest and highest branches, which are essential for tree health. Our certified arborists only recommend crown reduction when absolutely necessary.

Tree Topping

Removing the top of a tree is dangerous work and should be avoided at all costs. Tree topping can cause decay and other tree problems. Our arborists will do anything they can to avoid unnecessary tree topping.

When’s The Best Time For Tree Trimming?

Ideally, you should have Drendel’s Tree Service Certified Arborist assess your trees annually. Drendel’s tree pruners and tree trimmers will generally prune deciduous trees every 1 to 3 years and your conifers every 5-10 years. Portland tree trimming can be addressed throughout the year. However, we don’t prune some varieties of oak trees during April, May, and June to prevent oak wilt disease. Fruit trees should be trimmed in the fall.

Our ISA-Certified Arborists® and professional tree pruners and tree trimmers can help you pick the perfect time to prune your specific trees. Call Drendel’s Tree Service at (503) 654-3065 for a free estimate and consultation.
