There is a version of the tree service industry that most homeowners know too well. The crew that shows up late, leaves debris behind, and does not return calls after the job is done. Then there is Strobert Tree Services, which has spent 25 years building a reputation by doing the opposite of all of that.
Founded in 2000 by Andy Strobert in Wilmington, Delaware, Strobert Tree Services has grown from a one-man operation with a chainsaw and a pickup truck into one of the most trusted tree care companies in the Delaware Valley. With five office locationjs, ISA-certified arborists, more than 100,000 trees cared for, and a 100% satisfaction guarantee, Strobert serves homeowners and commercial clients across all of Delaware and Southeastern Pennsylvania with the kind of consistency that only comes from genuinely caring about the work.
How It Started
Andy Strobert did not start with a business plan and a startup loan. He started after high school with his father’s chainsaw and the family pickup truck. That origin story matters, because it set the tone for everything the company became. It is the kind of founder story that rarely gets told in the tree care industry, but it should.
Working close to the ground, literally, from the beginning gave Strobert a hands-on understanding of tree work that no office career could replicate. He learned early that the work itself demands respect, for the trees, for the property, and for the people who trust you to do the job right. Those values became the foundation of Strobert Tree Services, and they show up in how every member of the team operates today.
Twenty-five years later, the company serves all of Delaware and Southeastern PA through five regional offices, with ISA-certified crews, low-impact equipment, and a mission that has not changed since day one: “Achieving complete customer satisfaction by providing safe solutions to their needs.”
Services for Homeowners and Businesses
Strobert offers a full range of residential and commercial tree care services. Whether a homeowner needs a single tree removed or a business property requires comprehensive plant health management, the team brings the same standard of care to every job.
Tree Removal
Tree removal is one of the most physically demanding and risk-intensive jobs in property maintenance. Done wrong, it damages roofs, fences, and neighboring properties. Done right, it looks clean, simple, and almost effortless. Strobert’s tree removal service delivers the latter consistently, using specialized low-impact equipment that protects your lawn, garden, and structures throughout the process.
The International Society of Arboriculture consistently emphasizes that large tree removal should never be treated as a DIY project. Falling hazards, proximity to structures, and unpredictable branch behavior make professional assessment essential. Strobert’s ISA-certified arborists evaluate each removal site before a single cut is made.
Pruning
Pruning is about more than appearance. Properly pruned trees are structurally stronger, less prone to disease, and safer during storms. Strobert’s certified arborists shape and strengthen trees with a focus on long-term health, removing dead wood, improving canopy structure, and reducing the risk of limb failure during high winds.
The Tree Care Industry Association (TCIA) recommends routine pruning every two to three years depending on species and age, making it one of the most consistently valuable investments a property owner can make in their landscape. Strobert’s team advises clients on the right schedule for each tree on their property, rather than applying a one-size approach.
Stump Grinding
A leftover stump is more than an eyesore. It is a tripping hazard, a potential magnet for termites and other wood-boring insects, and an obstacle that prevents grass from growing evenly. Strobert’s stump grinding service eliminates stumps quickly and cleanly without tearing up the surrounding lawn, restoring the yard’s appearance and usability in a single visit.
Plant Health Care
Trees are living investments. A mature shade tree adds measurable value to a property, with research from the USDA Forest Service consistently showing that well-maintained trees increase residential property values by as much as 10 to 15 percent. Protecting that investment requires more than occasional pruning.
Strobert’s Plant Health Care program inspects, diagnoses, and treats trees for disease, pest infestations, and soil conditions that affect long-term vitality. The team works proactively, identifying problems before they become costly emergencies and recommending treatments that support root health, nutrient uptake, and structural resilience.
Cabling and Bracing
Some trees have sentimental or historical value that makes removal the last option anyone wants to consider. When a beloved tree develops structural weakness, split crotches, or heavy lateral limbs that pose a risk, the right answer is often cabling. Strobert’s cabling services install high-strength support systems that reduce the risk of limb failure while preserving the tree’s natural form and long-term viability.
Storm Damage Response
Delaware and Southeastern Pennsylvania see their share of severe weather. Nor’easters, summer thunderstorms, and ice events regularly bring down limbs, split trunks, and drop trees onto roofs, driveways, and fences. When it happens, the last thing a homeowner needs is to wait a week for a callback.
Strobert’s storm damage team operates 24 hours a day, seven days a week. They respond fast, work safely, and leave properties clean. One Newark homeowner described the experience directly: “After a big storm, Strobert had a crew at my house the next morning. They were calm, respectful, and took care of everything safely.” That kind of response is not accidental. It reflects a company that understands how much a storm-damaged yard weighs on a family until someone shows up and fixes it.
Commercial Tree Services
Strobert’s commercial tree care program serves property managers, municipalities, schools, HOAs, and businesses throughout Delaware and Southeastern Pennsylvania. Commercial tree work requires coordination with other contractors, adherence to liability requirements, and the ability to work efficiently across larger properties without disrupting daily operations. Strobert’s project managers and job superintendents have spent careers in the field and bring the decision-making experience that complex commercial jobs demand. It is the kind of operational depth that separates established local businesses from the competition, a distinction covered regularly in local business coverage across the region.
Credentials That Matter
Tree care is an industry where credentials separate the professionals from the people who own a chainsaw and a trailer. Strobert holds every major certification and license relevant to the region.
The company’s arborists are ISA-Certified Arborists, a credential that requires passing a rigorous examination and maintaining ongoing continuing education in tree biology, diagnosis, and care. Strobert is also accredited by the Tree Care Industry Association, one of the most respected third-party quality standards in the industry.
Licensing covers all primary service states. Strobert holds Delaware Department of Agriculture licensure, Pennsylvania Department of Agriculture certification, Maryland Licensed Tree Expert status, and Board of Tree Experts recognition in New Jersey. The company is fully licensed, bonded, and insured in every jurisdiction where it operates. Wells Fargo financing is available for qualifying projects, and Strobert offers a Senior Tree Removal Program with discounted services for older homeowners who need help managing safety concerns on their property.
Five Offices Serving Delaware and Southeast PA
Strobert’s reach across the region comes from a deliberate investment in local presence. Rather than operating as a distant company dispatching crews from a single location, Strobert maintains five offices positioned to serve the full Delaware Valley region efficiently and personally.
- Wilmington, DE (Headquarters): 1806 Zebley Road, Wilmington, DE 19810. The original home of Strobert Tree Services and the anchor of their Delaware operations.
- Georgetown, DE: Serving downstate Delaware communities including Lewes, Rehoboth Beach, Seaford, Millsboro, and Laurel.
- Exton, PA: Positioned to serve Chester County communities including West Chester, Kennett Square, Downingtown, and Concordville.
- Bryn Mawr, PA: Covering the Main Line and surrounding areas including Wayne, Havertown, Swarthmore, and Newtown Square.
- Schwenksville, PA: 458 Swamp Pike, Schwenksville, PA 19473. Serving Montgomery County communities including Pottstown, Norristown, Lansdale, and Phoenixville.
That footprint means a Strobert arborist is never far from where you need them. Whether you are in Newark or Hockessin in Delaware, or West Chester, Wayne, or Phoenixville in Pennsylvania, the team that shows up knows the area’s trees, soil, and weather patterns from direct experience. Other locally rooted home service companies across the Delaware Valley have built their reputations the same way: by staying local, showing up, and doing the work right.
What Homeowners Actually Say
The reviews that follow Strobert across Google, Angi, and HomeAdvisor share a consistent pattern. Customers describe arborists who took time to explain the work. Crews who showed up on time, stayed until the job was done, and left properties cleaner than they found them. A company that returns calls and follows through.
“The arborist took time to explain everything, how and why they were doing it that way,” wrote Lucy H. from Hockessin. “They showed up on time, did all the work just like they said, and cleaned up really well before leaving. If we need tree service again, no doubt we will call them. I tell everyone about this company.”
Zachary M. from Middletown, DE described calling Strobert after another company failed to show up: “Strobert actually picked up the phone and scheduled us same week. They came out, removed a dying tree, and even hauled away some extra branches we had. Real solid service.”
That word, solid, comes up repeatedly in Strobert reviews, and it is the right one. Not flashy, not oversold. Just a crew that does what they said they would do, when they said they would do it, without leaving a mess behind.
Sustainability at the Core
Tree care done carelessly leaves an environmental cost. Chips and logs sent to landfills. Root systems damaged by heavy equipment. Soil compaction that affects neighboring trees for years. Strobert approaches this differently.
Their sustainability planning incorporates plant selection, soil fertility, sun exposure, irrigation needs, and wildlife habitat considerations into every job. Materials from tree removal are recycled into lumber, mulch, and other products rather than disposed of. Low-impact equipment, including specialized cranes and root-saving ground protection, minimizes disturbance to the surrounding landscape during even the most complex removals.
The 50 Shades of Green tree care glossary on the Strobert website is one practical expression of that commitment to education. It is a free resource covering dozens of tree care terms in plain language, designed to help homeowners understand what is happening on their property and make informed decisions about the care their trees need.
Corrin Kiln Dried Firewood
Strobert’s sister brand, Corrin Kiln Dried Firewood, delivers premium kiln-dried firewood that the company guarantees can be lit with a single match. It is not a side project. It is a natural extension of a company that handles wood every day and understands what properly dried, seasoned firewood should look and perform like. For homeowners in Delaware and Southeast PA who rely on a fireplace or wood stove through the winter months, it is worth knowing this option exists from the same people they already trust for their trees.
Getting Started with Strobert
Every Strobert job starts with a free consultation. Not a call center. A real arborist who will listen to what you are concerned about, look at what you are dealing with, and give you honest advice about what needs to happen and what does not. There is no pressure, no upselling, and no guesswork about cost.
For urgent situations, the 24/7 emergency line means help is never more than a phone call away. For scheduled work, most clients are seen quickly, and the scheduling process is designed to fit around the homeowner rather than the other way around.
Strobert also runs a referral program for satisfied customers who want to share the experience with their neighbors, which is exactly how most new Strobert clients find them in the first place. Word of mouth is still the most honest review a tree service can receive.
