Tree Care, Pruning & Removal in Seattle

Frequently yes, and it is the first thing to check rather than the last. Seattle regulates tree removal on private property, with additional protection for larger and designated exceptional trees and for anything inside an Environmentally Critical Area — which covers steep slopes, landslide-prone ground and riparian corridors across much of West Seattle, Magnolia and the eastern hillsides. Rules also differ between Seattle and the Eastside cities we work in, so a Bellevue or Sammamish property is a separate question. We establish the position for your specific parcel before work is scheduled. Removing a protected tree without approval carries real penalties.

No, and it is worth being direct about this because it is still commonly requested. Topping a conifer removes the crown that the tree balances against, triggers a mass of weak regrowth from the cut, and creates decay pockets where water sits in the severed leaders. The result within a decade is a tree that is genuinely more likely to fail than the one you started with, and one that can no longer be made safe by any means short of removal. The legitimate alternatives are crown thinning to reduce wind loading, deadwood removal, and honest assessment of the root plate and lean. If a tree really is a hazard, removal is the answer, not topping.

It can, and on a sloped Seattle lot it sometimes does. A mature conifer moves a substantial volume of water out of the ground through the growing season and its root system binds the soil it sits in. Take it out on a hillside and you may find both a wetter lot and, over the following years, a slope that has lost some of what was holding it. That is not an argument against ever removing a tree — a dangerous one has to go — but it is an argument for knowing before you commit, particularly on the bluff and hillside properties where these two effects matter most. Where it applies, we would look at drainage as part of the same conversation.

After it is ground out properly and the void is dealt with, yes. Grinding leaves a hole full of wood chip and soil, and wood chip decomposes and settles — build a patio base straight over it and you get a dip in the surface two or three years later, exactly in the spot you cannot patch invisibly. The correct sequence is grinding below grade, excavating out the grindings and any large residual roots, and backfilling with compacted structural material before the base goes on. It adds a stage, and it is a great deal cheaper than lifting a section of finished patio.
