Residential Tree Services

With our regular maintenance and arborist services, your trees and shrubs will thrive for years to come. Investing in your landscaping will provide lasting rewards in the form of a beautiful, safe, pest-free environment, and will increase your property value while minimizing risks. In short, we will turn your home’s outdoor environment into a peaceful haven to savor during your downtime.

No two properties are alike, so we start by crafting a bespoke maintenance plan for your home landscaping, based on our assessment and your stated priorities. We then get to work to meet the goals of that plan, which might require us to remove a tree, prune and trim plants, apply pesticides, herbicides or fertilizer, grind down a stump, remove brush, and so on.

Tree Removal

When it comes to removing trees, it’s best to leave it to the professionals. Trying to remove a tree by yourself is not worth the risk of severe injury or damaging your property. A trained crew of arborists have the necessary knowledge and equipment to do the job safely and efficiently.

Our certified tree specialists have the knowledge and experience to effectively and securely remove dead, diseased, or unwanted trees without damaging your landscape or structures. Our professional crews use the latest equipment and machinery to remove trees of all sizes, working methodically as a coordinated team to ensure a job well done. Better yet, we guarantee your satisfaction with our work.

“Awesome job – quick and great about moving all garden items out from under the tree before starting. Well worth the extra investment – especially after the crazy weather we have had the past year! Crew was friendly and answered all my questions.”

Tree Trimming and Pruning

We specialize in trimming and pruning procedures that shape your trees to be aesthetically pleasing while also supporting plant health. Have no fear, we’ll consult with you first to ensure that we’re on the same page for what you want. Once we start making cuts, we’ll work precisely and meticulously, taking our time to do the best possible job.

Our goal when pruning is to accentuate the trees’ beauty, remove potentially hazardous limbs, and enhance the health of nearby plants by increasing airflow and penetration of sunlight into the understory. By the end of our process, you’ll admire the graceful shape and open views that enhance your landscape, without drastically changing its character.

Stump Grinding

A stump left behind can cause all sorts of problems, from attracting pests like termites to becoming a tripping hazard and making it difficult to mow. It can also lower your property’s value. Plus, stumps often send out sprouts that grow rapidly every spring, requiring constant trimming to prevent a new tree from growing.

The best way to get rid of a tree stump is to hire our stump grinding crew. We have the latest tools and technology, and will effectively grind the stump down into wood chips, making sure not to damage your soil or plants in the process. All you’ll be left with is a pile of wood chips!

Plant Health Care

We know the health of your valued ornamental plants is a top priority. That’s why we draw on our expertise and experience to care for and nurture your plants as if they were our own.

Trees that are healthy and well-cared-for are more attractive and resilient to harsh weather conditions, pests, and diseases. By taking a holistic approach to plant health care that includes practices like precise pruning, fertilization, and pest or weed management, we can enhance the vitality of your entire landscape. This not only makes your outdoor environment more enjoyable to spend time in, but also requires less work to maintain.

Pest Management

Insects, fungi and bacteria can wreak havoc on a vulnerable landscape environment. It’s always best to prevent plant pests from doing damage in the first place. But if you do have an invasion of pests, it’s important to take decisive measures to nip the problem in the bud before it’s too late. Our trained and licensed pesticide applicators will identify the problem, determine the level of treatment necessary and get rid of the pests for good.

Weed Control

Weed control is essential to allow your plants of choice to thrive. Otherwise, unwanted weeds will compete with your plants for water, nutrients and sunlight. Our certified weed control specialists will mitigate and minimize the unwanted plants or apply fertilizer where needed. We’ll be sure to check in with you about our plans before using herbicides, and are happy to answer any questions you might have about our products or processes involved.

We employ licensed herbicide applicators who are experts at controlling and limiting weed growth. We will provide guidance on when and how often weed control will be necessary, with a typical plan focusing on first knocking back weed growth to restore your landscaping, followed by targeted spraying before the weeds put out seeds. Doing so will shrink the weed population until it is eliminated or minimized as much as possible
