"Mike and his crew are true professionals. I would hire again without any hesitation. They removed 50' of tall hedges and 5 evergreen trees. They completed the removal and cleanup in under 2.5 hours. They were very careful not to damage other vegetation or personal property of our house and our neighbors. And dug out 2 trees by hand because they wanted to make sure that no electrical or water lines were damaged. I wish all the pros we hire were as skilled and professional as this crew."

"Excellent Tree Removal Service by LA Arbor Care In March 2023, our plumbers told us that our sewer pipe ran right under our large Deodar multi trunk pine tree, and that the treeâ  s massive roots had detrimentally damaged the sewer pipe leaving us with no other option other than to remove the tree and grind the stump so they could dig a hole under it to repair the pipe. We received four estimates from different tree removal companies. Miguel Lopez at LA Arbor Care did not provide the least expensive estimate, but we felt that his considerable experience, certifications, and great reviews made his firm our best option. We are so pleased that we selected LA Arbor Care to do this work. They did the work exactly as promised, removing the tree safely and efficiently. We were impressed by their work ethic and quality, and they were very careful not to damage the power and data lines that were coming through the tree branches. They were conscientious about leaving the entire work site impeccably clean â  for example, the tree was adjacent to our swimming pool, and unprompted, they cleaned all the leaves and branches that had fallen into the pool during their process of taking down the tree. Miguel and his staff were friendly and professional. I would highly recommend them to anyone who needs tree removal services."

"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."

"Went great. They showed up on time and did a fantastic job. They covered the pool filter with plywood to avoid any damage from falling palm parts. The carrotwood tree belonged to the neighbor but extended into my yard too. They trimmed that nicely on both sides. They also trimmed the Bougainvillea's back to separate the neighbors tree from my side. Cleaned up nicely afterward too. (No dirt or anything in the pool! or the street). Highly recommended. Will use again."

Arborists questions, answered by experts

If it’s only a smaller branch that has died and you’re keeping an eye on the tree, it’s probably nothing to worry about. But if other nearby branches start dying off as well, or a very large branch dies, then you likely have a bigger problem. It’s time to watch for diseases and other problems and possibly get professional guidance on how to proceed.

You can use a chainsaw, but it won’t remove the entire stump or root ball and is not a recommended method. It takes quite a bit of physical work to achieve and will likely dull or ruin your chainsaw. Instead, consider using salt, herbicide, light deprivation, boiling water, stump grinding, or burning to kill a tree stump. These methods allow you to kill a stump using minimal machinery and physical exertion.

The amount of time it takes for a tree trunk to rot depends on several factors, including the tree’s size, species, and environmental conditions. It can take anywhere from a few years to several decades for a tree’s trunk to rot. A tree stump, on the other hand, can take up to 10 years to disappear after it’s decayed naturally.

The best tools for tree removal include a chainsaw for large trees, an ax for notching and cutting down small trees, and a wedge to help control the direction a tree falls in. A hatchet can be useful for very small trees, but won’t be effective for medium to large trees. 

You should not trim an oak tree in the summer. Oak trees are especially susceptible to disease, and open tree wounds are an invitation for beetles that carry tree-killing fungus. If there’s no risk that the oak tree will do damage to your property or hurt someone, it’s best to save the trimming for fall or winter. If you can, seal the wound with latex to prevent fungus from getting inside.
