Licensing requirements for arborists, also known as tree surgeons, vary by state and municipality. Many areas require a license, which often involves specialized education and experience. Even if not mandated, it's wise to hire a licensed professional as they tend to have more experience. Beyond licensing, look for certifications from organizations like the International Society of Arboriculture (ISA) or the Tree Care Industry Association (TCIA), as this indicates a higher level of expertise. Certified arborists must typically pass a comprehensive exam. Always confirm that the arborist has a business license and is fully insured to protect yourself from liability. Seeking positive recommendations from local homeowners is also a good step in finding a qualified professional.

We don’t recommend DIY tree trimming for a few different reasons. First, the tools required to trim a tree can be costly, up to $1,100 or more, for the ladders and specialized saws needed. 

Safety is another concern, especially when working with more mature trees. As a guideline, you should only DIY tree trimming when branches are less than two inches in diameter. Any more, and the safety risk becomes too high, which could lead to catastrophe. For this job, it’s safest to let a tree-trimming professional assess the work needed.

Since each tree is different, it’s impossible to say how long a dead tree can remain on your property. While it could be days, months, or even years, it’s highly likely that, at some point, the tree will fall. In the meantime, dying or dead trees can become a haven for pests, so it’s best to have them removed sooner rather than later.

Yes, carefully prune back dead branches—don’t wait for pruning season. This helps keep your maple tree healthy and also helps prevent large branches from falling unexpectedly. Don’t seal the cut branch—trees can naturally take care of these wounds—but be sure to remove any source of fungus or pest infestation to help save the tree.
