Frequently Asked Questions

ISA certification requires passing a rigorous exam covering tree biology, pruning standards, soil science, pest identification, and safety. Every assessment and removal scope we complete is guided by that credentialed standard.

Most single-tree residential removals finish within a half to full day. Multi-tree jobs typically take one to two days. We provide an accurate time estimate before scheduling any work.

Trees near structures and utility corridors require directional felling, sectional cutting, and rigging. We assess all infrastructure proximity before work begins and coordinate with utilities when the situation requires it.

Full debris removal is included in every job. Wood, branches, and brush are chipped or hauled away before we leave. Just ask if you want firewood sections or chips kept.

We respond to emergency tree situations at any hour when site conditions allow safe work. We prioritize emergency calls above all scheduled work and confirm response windows through our contact page.

Most established trees benefit from a pruning assessment every three to five years. Trees near structures or with rapid growth rates may need more frequent attention than that general guideline suggests.

Stump grinding chips the stump and surface roots in place below grade. We typically grind 8 to 12 inches deep, or deeper when replanting or hardscape installation requires additional clearance.

In many cases, yes. Root stress, soil compaction, fungal disease, and pest pressure are treatable when caught early. Our arborists assess recovery potential honestly before any treatment commitment is made.

We produce formal written arborist reports for permit applications, insurance claims, property transactions, and legal matters throughout the Portland, Oregon area. Contact us through the contact page to discuss your requirements.

Root collar excavation removes soil and mulch buildup against the trunk base. A buried root collar promotes crown rot and bark disease at the tree's most structurally vulnerable point.

Portland, Oregon's Title 11 tree code requires permits for removal and significant pruning above certain size thresholds. All About Trees LLC reviews permit requirements for every project scope before work begins.

Crown thinning selectively removes branches to improve airflow and reduce wind resistance while preserving natural structure. Topping removes the upper crown indiscriminately, causing wounds, weak regrowth, and long-term structural decline.

Specialty shrub pruning is a core part of what we offer. We work on rhododendrons, Japanese maples, formal hedges, espaliered plants, and weeping conifers throughout the Portland Metro area.
