Tree Removal

Freshly sawed log with tree rings

Our tree removal service in Washington, DC, Maryland, and Northern Virginia can help improve the health and beauty of your property. Removing dead and diseased wood helps to prevent infection and encourages growth of other trees and plants.

It’s sometimes necessary to cut down a tree that is still alive. Storm damaged or leaning trees can threaten structures and residents. Overgrown root systems can threaten foundations and other trees or plants. These issues can be resolved with tree removal services. 

We ensure a thorough removal of all parts of a felled tree including trunk, limbs and branches, and stump. Our tree removal services include hauling debris, stump grinding, log splitting, and chipping and mulching. 

Tree Trimming

Guardians offers tree trimming and pruning in DC, Maryland, and Northern Virginia to remove branches that are overgrown, threatening structures and other trees, or loose and dead. Removing unhealthy branches helps trees to develop a strong core structure, guard against infection, and increase production of flowers and fruit. Overall appearance of the tree will also improve.

After trimming, our team is careful to clean up branches and debris for you. Guardians Tree takes great pride in leaving your lawn looking great. 

Stump Grinding

Huge old stump against a green lawn

Do you have any stumps left over from trees that were cut down a long time ago? Guardians’ stump grinding services can help.

A tree stump may be infested with insects, mold, and bacteria. Large, hidden stumps can become a safety hazard. Stumps also make mowing your lawn harder than it should be.

Removing a stump requires specialized equipment that most homeowners simply don’t have the money to buy or the time to learn. Contact Guardians Tree and Landscape to have us safely remove your stumps for you in Washington, DC and the surrounding areas in Maryland and Northern Virginia.

Insect and Disease Control

Aphids on cherry leaf

There are many parasites and diseases that homeowners need to guard against. Insects that can harm your lawn and home include aphids, Asian long-horned beetles, black turpentine beetles, eastern pine shoot borers, emerald ash borers, and fall webworms. These pests can stunt new growth, introduce fungi and toxins, and weaken the internal structures of trees. Viruses and diseases can infect leaves, shoots, twigs, and wood. Anthracnose are particularly persistent and can remain in a tree from one season to the next.

Fortunately, Guardians Tree and Landscape offers insect and disease control services for removing insects and diseases from your property. Contact us today for your pest control needs in the DC, Maryland, and Virginia areas.

Storm Damage

Storm damaged tree broken

Debris left behind by a storm is unsightly, but even worse it can cause a safety hazard as damaged trees or limbs lean or hang dangerously, threatening to fall over at any time. The damage could also weaken the wood, leading to a compromised internal structure. Guardians’ storm damage cleanup services will help to restore your property to its natural beauty after a damaging storm and improve safety for all.

Damaged trees may lean dangerously, have weakened wood, loose branches, injured roots, and a compromised internal structure. Our storm damage cleanup services include tree trimming and pruning, tree removal, and hauling of branches and debris. Trimming and pruning will get rid of dangerous or dead branches in order to save the tree, while tree removal may be appropriate for trees that cannot be saved.

Tree Health Care

A tree health care or plant health care program consists of a partnership with a trained and experienced arborist, who will help you monitor your trees, prevent and treat issues, and enhance your property.

Guardians offers many techniques to enhance the health of the trees on your property. Air spading breaks up difficult soil, allowing you to prevent root rot, help the roots to absorb nutrients and water, and correct circling roots. Fertilization fosters health in both young plants and old trees. Our tree risk assessments by Master Arborist Steve Castrogiovanni will evaluate the health of your trees and identify issues before they become a major problem.


Beautiful lawn with flower bed and stone wall

Our landscaping services — including installation, mowing, and mulching — can improve your lawn as well.

Landscape installations transform a lackluster lawn into a beautiful piece of real estate. We will evaluate ways to make your lawn more aesthetically pleasing and develop a layout that makes the most out of your existing trees and plants.

Guardians offers mowing and mulching service as well. Mulching improves the health of your lawn’s trees and plants by encouraging new growth and improving nutrient absorption.
