Tree Removals Are Our Specialty

Contact General Tree Service if you want a stress-free tree removal as our skilled crews show up on time with the right equipment and tools. Whether it's an evergreen by power lines or a giant sequoia by your house, we always follow strict protocols to keep everyone safe.

• Climbers use safety lines when working above 15 feet
• Ground crew uses safety devices to control traffic
• Only trained employees allowed to work within 10 feet of energized lines

Tree removals should be hassle-free for home and business owners. That’s why we handle everything from start to finish. From making the first cut to hauling away debris, to removing the stump with stump grinding, we will complete the job so that you have nothing to worry about.

Tree Trimming and Pruning for Safety and Plant Health

General Tree Service has pruning crews led by certified arborists who always follow ANSI guidelines for the best results of tree pruning services. We are proficient in all types, including hazard reduction, maintenance, or specialties like detail pruning for high-value trees or structural pruning on younger trees to ensure they grow structurally strong.

Responsive Emergency Tree Service

We strive to make the situation as stress-free as possible. Upon arrival, we’ll make a quick assessment and take care of any immediate dangers to prevent further damage.

After careful evaluation, we’ll explain what needs to be done and if presenting multiple options, will explain the pros and cons of each. Our goal is to give you all of the critical information so you can make the best choice.

Dealing with trees downed by a storm requires the right equipment and experience to prevent further damage. Having trained professionals make all the difference between having the job done right and incurring more destruction when an inexperienced company doesn’t follow proper procedures.

All our employees receive training in proper safety procedures as we’re not only concerned about our crews, but also your family and property. Standard procedures include wearing appropriate personal protection equipment, state of the art to lower large limbs, and placing safety devices to control pedestrian and vehicular traffic.

Plant and Root Health Care

At General Tree Service, there are two ways we accomplish this:

•  Insect and Disease Control: Our technicians are trained to recognize insect, disease, and cultural problems and will treat affected plants only when needed. This results in a healthier landscape and benefits our environment by limiting the number of materials applied.
• Root Health Care: The root mass is a tree’s natural delivery system for water and nutrients and you can’t have a healthy tree if it’s not getting proper water and nutrients. Think of the roots as straws. Root Zone Enhancement and Root Collar Excavation are part of our holistic approach as they focus on restoring ideal growing conditions to the root mass.
