Insurance is the entire ballgame
Start and nearly end here: tree removal above a house is the trade where things go catastrophically wrong, and Texas licenses none of it. Require certificates of liability and workers comp sent directly from the insurance carrier before anyone climbs, because if an uninsured climber gets hurt in your yard or a limb goes through your neighbor's roof, the bills find their way to you. A crew that hesitates on insurance is a crew you cannot afford at any price.
Voluntary credentials and the topping test
Certified arborist credentials are voluntary in Texas but meaningful: they signal someone trained in how trees actually work. And there is a free instant filter: ask how they would handle your biggest tree, and if the answer is topping it, cutting the whole crown to stubs, thank them and call the next crew. Topping ruins trees and marks an outfit that does not know or does not care.
Oaks and this coast
For live oaks, ask two Texas-specific questions: when do you avoid pruning oaks, and do you paint the cuts? A crew that knows the oak wilt window and seals oak cuts as a matter of course knows Texas trees. And ask how they protect what stays: your roof, your fence, the yard, and the tree itself. Rigging and lowering piece by piece costs more than dropping wood, and it is the difference you are paying for.
- Liability AND workers comp, verified direct from the insurer
- Certified arborists are voluntary and a genuine signal
- Anyone quoting topping is disqualified

What should I check no matter what?
Four things, every time: proof of liability insurance sent directly from their insurer, not a photocopy; how long they have worked this area under this name; local references you can actually call; and a written scope before any money moves. Anyone offended by those four is answering your question.
