Brian started Root Cause in 2010 after decades as a Certified Arborist and running another Tree Service Business in Western Washington. He began to see how trees were impacted around construction sites and how trees began to die years after the project was done. He concluded that it was the impact on tree roots during and after the project that hurt trees the most. Root Cause is an underground tree service, meaning we work with city municipalities to protect trees and their roots. This includes setting up tree protection sites around construction projects, root exposure, analysis, & pruning, and side walk repair. If you have questions about trees in your city, please give us a call or email.
