Trees might need removal due to safety concerns like disease, decay, or structural instability. Additionally, if they're causing damage to structures or obstructing utility lines, removal may be necessary.

Dead or dying trees pose significant safety hazards as they're more prone to falling, especially during storms or high winds. They can cause property damage, injury, or even fatalities.

Signs that a tree may need removal include extensive decay, large dead branches, visible cracks or splits in the trunk, leaning at an angle, or signs of disease like fungal growth or wilting leaves.

Tree stumps left in the ground can attract pests, become obstacles for landscaping or construction, and regrow if not properly treated. Removing stumps improves aesthetics, safety, and usability of the space.

While trees play vital roles in ecosystems, sometimes their removal is necessary for safety or development reasons. However, it's essential to consider replanting trees elsewhere or implementing other environmental mitigation measures.

Look for licensed and insured professionals with experience and a track record of safety. 

The size, species, condition, and location of the tree, as well as accessibility to the site and any additional services required (e.g., stump removal, debris cleanup), can all affect the cost.

DIY tree removal can be dangerous and is not recommended for most people. It requires specialized equipment, knowledge of proper techniques, and safety precautions. Stump removal may be more feasible for some homeowners with the right tools and experience.

 The duration depends on various factors such as the size and complexity of the tree, equipment used, and site conditions. Tree removal typically takes a few hours to a day, while stump removal may take longer.
