Yes, it is essential to confirm that any tree service company you hire is properly insured before they begin work. Tree removal, trimming, and pruning are dangerous jobs, and proper insurance protects you, your home, and the company from liability in case of accidents or damage. Look for a company that carries both general liability and workers’ compensation insurance, and do not hire one that cannot provide proof of coverage. When browsing for professionals, you can look for indicators like an “Angi Approved” badge, which signifies that the business meets standards like holding applicable licenses and passing a background check. Keep in mind that a license is a legal requirement to operate, while certifications are typically voluntary.

Generally, avoid trimming trees in the summer (with the exception of pruning fruit trees as needed). Trees use a lot of energy in the summer, most of which is relegated to new growth. If you chop it too early, you could stunt the next season's growth. Again, when in doubt, do some research based on the specific tree type.

Palm tree stumps can take as long as seven to ten years to rot naturally. Whereas some tree stumps rot within a year, palm trees tend to last longer due to their deep root networks. Chemical rotting (described above) can help speed the process up so your palm tree stumps rot in under two months.

A tree growing close to a house can pose several risks, but removal isn't always the only or best solution. Potential problems include roots growing into the foundation and causing structural cracks, branches damaging the roof or promoting moss growth, and debris clogging gutters, which can lead to water damage. Trees can also provide access for pests and encourage mold. However, a small, healthy tree may not be a problem, and for larger, established trees, strategic trimming can be a cheaper and more beneficial alternative to removal. It is generally recommended to take action for trees within 10 to 20 feet of your home, especially if they are unhealthy or encroaching. Your best bet is to consult a professional arborist who can assess the specific situation and provide expert advice.
