"I recently had Lead Saw Tree Service take out a tree from my yard, and it was such a breeze. They were super easy to deal with from the moment I asked for a quote to when they showed up on time and got the job done within the schedule they promised. It made my day so much easier and stress-free. I'd definitely recommend Lead Saw Tree Service for any tree removal job."

"Gilbert (the Project Manager) was responsible, reliable and on time. They brought all the necessary equipment to do the job (tree removal), they proceeded to do the job without any hiccups and finally cleaned up after the work was done. They were very professional and respectful. I highly recommend them and I will be using them for future projects."

"INCREDIBLE! This was the first time that my trees have be pruned and shaped correctly in over 40 years. I am so happy with the work. One tree was next to my pond; the crew put a large tarp over the pond so no debris fell into it, so I didn't have any pond clean up work to do. My yard was left in better shape than when the crew got here. I am planning on asking them to come back in the spring to get my winter garden in shape for the growing season."

Arborists FAQs, answered by experts

The best time to trim trees is in late fall through winter when the tree has slowed its growing for the year. Cold weather stops insects and fungal growth from attacking a new tree wound. Summer and fall are considered the worst times to trim trees, but it’s permissible in certain scenarios, such as tree disease, damaged branches, or small, aesthetic cuts.

Palm trees are unique in that their roots don't grow straight down; they grow horizontally. Typically, palm tree roots go down between 12 and 36 inches deep. The roots grow far and wide from the base of the palm tree to absorb as much water and soil nutrients as possible. In addition, the horizontal roots are also very strong—keeping palm trees stable and helping them sway during storms.

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.

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.

Permits are often required for large tree removals, especially in urban areas or for protected species, ensuring regulation compliance and neighbor safety.
