I have a mature TPO oak tree close to the house. It has fungus at the base with rot in the trunk. An arborist has indicated that for safety reasons the tree will soon need felling. However we’re on clay soil and reading some surveyor’s advice online they suggest removing the tree could cause heave with damage to foundations due to the ground re hydrating. That said I’ve read conflicting arguments from surveyors and arborists both agreeing and disagreeing with this observation. Thoughts?
