Ask an Arborist

At Tree133, our arborists use advanced climbing techniques and specialized gear to safely navigate tall trees. By setting ropes and anchors high in the tree, they ensure both safety and efficiency while working. Think of them as industrial athletes, combining skill and precision to care for your trees.

Climbing spurs or spikes are only used on trees that are being removed. The professional arborists at Tree133 never use climbing spurs in healthy trees that are being pruned or inspected. This out-dated practice is a direct violation of the ISA Certified Arborist code of ethics.(https://pnwisa.org/page/codeofethics) The sharp points on climbing spurs are extremely damaging to tree bark and the cambium beneath. The use of climbing spurs for pruning (not tree removal) will cause irreparable damage to your trees. https://static.wixstatic.com/media/287e7d_af81733a50fa42ce98a50722a4e7ba37~mv2.jpeg

Our arborists use hand tools as often as possible. Many of our chainsaws are battery-operated and significantly quieter than gas-powered equipment. Our team typically uses Bluetooth headsets inside their helmets, so they can talk to each other without shouting. https://static.wixstatic.com/media/287e7d_b6d60561291f420299950eb437f0ed08~mv2.jpg We know you don't want to listen to a chipper run longer than necessary, and neither to we. Our team will stack branches and debris, then only turn on the chipper when they can feed it efficiently and safely.

Yes, we do! In Seattle, rain is part of the job, and our arborists are well-prepared with the right gear to work year-round. Safety is always our top priority, so if high winds, lightning, or snow are expected, we carefully adjust schedules to keep everyone safe on-site and on the road.

If requested and if your tree is large enough, we can leave firewood for you. Other debris is chipped into the back of our truck. The resulting "arborist chips" (mulch) are excellent for spreading under your trees and in garden beds. As they break down, they return nutrients to the soil, help retain moisture, regulate soil temperature, and suppress weeds. Read more about how to properly mulch a tree.

Yes, you can! Many tree species are great for fireplaces or outdoor fire pits. Hardwoods like cherry, maple, madrone, and ash burn hotter and longer, while softer woods like fir and cedar are also excellent options. Keep in mind, unless we’re removing “deadwood,” the wood will need to dry for a season before burning. If we leave firewood-length pieces for you, they’ll still need to be split and seasoned for optimal use.
