Sometimes, you need more than someone with a pair of pruners or a chainsaw — sometimes you need the kind of expertise only an ISA-certified arborist can provide. RTEC Treecare is here to help in these kinds of situations, and our team of certified arborists is ready to help keep your trees vibrant, healthy, and safe.
Whether you need disease diagnostics or cabling and bracing services, our ISA-certified arborists are ready to step in with the guidance and hands-on support you’re looking for.
Slapping “arborist” on a business card costs nothing — and means nothing. ISA-certified arborist, though? That’s a different story. Earning that title means putting in years of real-world experience, passing a demanding and comprehensive exam, and staying committed to ongoing education just to keep the credential intact.
That’s why it carries so much weight with homeowners, property managers, and municipal staff. It immediately separates the truly knowledgeable from the rest of the pack. And when you think about how much trees contribute to a property — and the very real risks they can present when things go wrong — that level of expertise isn’t just reassuring. It’s essential.
Our certified arborists offer a wide range of services across the Vienna, VA area — from everyday tree care to the more unusual requests. Whatever you need, we’re happy to help. Here are some of the most common ways we work with our clients.
The Washington, DC metro area is home to a wide range of insects and invertebrates that can cause real headaches for your trees — from nuisance pests like aphids to genuinely destructive invaders like the emerald ash borer. Whatever you're dealing with, RTEC Treecare's certified arborists can identify the culprit and recommend the right course of action.
Fungal foliar infections, bacterial issues, viral illnesses — RTEC Treecare's certified arborists have seen it all and know how to handle it. We'll track down the problem and put together a treatment plan that actually makes sense for your tree. Most of the time, a visual inspection gets us there. When it doesn't, we collect samples and send them off for lab testing until we've got a definitive answer.
Structurally weak branch junctions are an accident waiting to happen — especially when a windstorm, blizzard, or heavy ice event hits. RTEC Treecare's arborists can step in and install advanced cabling or bracing systems to shore up those weak points and keep your trees intact and healthy when conditions turn ugly.
Healthy roots and good soil make all the difference between a tree that thrives for decades and one that needs to come down ahead of schedule. To give your trees the best possible foundation, our arborists can run soil tests, apply soil amendments, or carry out a root collar excavation when the situation warrants it.
Truth is, many tree problems are completely avoidable — and early pruning is one of the best tools for keeping them at bay. Shape a tree right while it's young, and you're setting it up for solid form and healthy growth for years to come. Whether that means tackling crossing branches, sorting out codominant leaders, or helping fruit trees develop the strength to carry a heavy crop, our arborists know exactly when and how to step in.
Construction work and trees don't always mix well. The damage it causes to trunks, canopies, and root systems can be permanent — and it often doesn't show up until the tree is already in serious decline. Get an RTEC Treecare arborist involved early, though, and you can avoid most of that damage altogether, giving your trees a real shot at coming through your project healthy and intact.
Trees don't always follow a script — and neither do their problems. Whatever you're dealing with, our arborists are happy to help. No question is too unusual, and no situation is too out of the ordinary for our team to take on.

While some tree-related problems are obvious, others can be surprisingly subtle. And because prompt, proactive care tends to lead to better outcomes, it’s important to monitor your trees for any of the following signs or symptoms, so you can provide them with the support they need.
Don't write off a dead, dying, diseased, decayed, or damaged branch as just a cosmetic problem — it rarely is. It's a potential safety hazard and often a warning sign that something more serious is going on under the surface. The sooner you get those branches evaluated and dealt with, the better your chances of protecting your tree and stopping any disease in its tracks.
Spotting mushrooms or conks on or around your trees isn't something to brush off. They're a sign of fungal activity — and often point to advanced decay already taking hold. Keep a close eye on your trees and the ground above their root systems, and don't wait to call in a professional if you notice any fungal growth showing up.
Not every leaning tree is a cause for alarm — but some are on the verge of coming down entirely. It takes the trained eye of a certified arborist to tell the difference and determine whether a leaning tree needs to be removed or whether another mitigation strategy can keep it safe.
There are plenty of insects that are harmless or even beneficial to trees, including pollinators and predatory species, such as ladybugs. However, other insects can sicken your tree, and some are even capable of killing trees outright.
Leaf and needle color changes don't always mean trouble — plenty of broadleaved trees do it naturally every fall. But when color changes happen outside of that, it's worth paying attention. Pest attacks, disease, and stress can all show up this way, and catching it early makes a difference.
Shifting, mounding, or cracking soil around your trees demands immediate attention — this isn't something you can afford to ignore. Once soil starts losing its structural integrity, the entire tree is at risk of windthrow or collapse. Get a certified arborist out there as soon as you spot it.
Hollows and cavities usually start with a wound — one that fungi eventually move into and call home. From there, the fungus works its way through the tree's tissues, causing decay that can slowly compromise the tree's structural integrity and put it at risk of failure.
When you see cracks or splits in a tree, the fibers are already giving way. That's not something to sit on — call an arborist the moment you notice it. Fast action means a proper assessment and the right mitigation steps in place before things get worse.

ISA certification is a great starting point — but it’s not the whole picture. You don’t want just any certified arborist; you want the best team you can find.
Here’s what we think makes RTEC Treecare stand out and gives our clients the peace of mind they deserve.
RTEC Treecare’s team is certified by the International Society of Arboriculture — but we didn’t stop there. We were also the first tree-care company in Virginia to earn accreditation from the Tree Care Industry Association (TCIA), and that’s something we’re genuinely proud of.
At RTEC Treecare, safety runs through everything we do. Every member of our team — ground crews, climbing arborists, and everyone in between — is fully committed to it. We keep the health and well-being of our clients, crews, and bystanders at the forefront of every job, and we won’t pick up a single tool until we know the work can be done safely.
Bad tree work leaves a mark — and not the good kind. Damaged landscapes, cracked hardscapes, compromised structures — it happens more than you’d think. We won’t let it happen to you. Our zero-impact techniques, including advanced rigging systems, ground protection mats, and cranes when the job calls for it, keep your property in great shape from start to finish.
Skill only gets you so far — having the right tools makes all the difference. That’s why RTEC Treecare invests in professional-grade equipment across the board. We’re talking everything from hand pruners and hard hats to cutting-edge diagnostic tools and aerial lifts. Whatever the job throws at us, we’ve got the gear to handle it right.
For more than 30 years, RTEC Treecare has been the go-to choice for homeowners, commercial property managers, and municipalities across Vienna, VA. Over that time, our arborists have tackled just about every tree-care challenge you can think of.

Clear communication is a priority for our arborists, and we make sure you’re always in the loop from your very first call or email right through to the day the job is done.
RTEC Treecare is fully licensed and comprehensively insured — not because we have to be, but because it’s the right way to do business. Our clients deserve that confidence, and we’re committed to earning it.

Some situations warrant a call sooner rather than later. If you notice a tree leaning that wasn't leaning before, large cracks or splits appearing in the trunk or at major branch unions, significant portions of the canopy dying back rapidly, heaving soil at the base of the tree, or a tree that has already dropped a large limb unexpectedly, those are signals that an arborist should take a look without delay. Concerns like gradual thinning, slow decline, or minor pest activity are still worth addressing but typically allow more flexibility in scheduling. When in doubt, it's always better to have an arborist evaluate sooner — catching a problem early almost always expands your options.
Pricing depends on the nature and scope of the visit — the number of trees being evaluated, the complexity of any structural or health concerns, and whether a formal written report is needed. Larger properties with established tree canopies naturally require more time than a single-tree assessment. We provide on-site estimates before any work begins so you have a clear, accurate picture of the cost. Visit rtectreecare.com to get in touch and schedule a visit.
Yes — and ideally, we get involved before construction begins rather than after damage has already occurred. Construction activity is one of the leading causes of tree decline and death in residential settings, and most of the damage happens below ground where it isn't immediately visible. Soil compaction from equipment, grade changes, root severance from trenching, and changes in drainage patterns can all compromise a tree's root system in ways that don't fully surface until years later. Our arborists can establish root protection zones, recommend barrier placement, and provide guidance to contractors on how to minimize impact. If construction has already taken place, we can assess the extent of the disruption and recommend a recovery plan.
These two evaluations serve different purposes and aren't always interchangeable. A tree health assessment focuses on the biological condition of the tree — evaluating foliage density, bark integrity, root health, pest and disease activity, and overall vitality. A tree risk assessment is specifically concerned with the structural likelihood of failure and the potential consequences if failure occurs. Some situations call for one, some call for both. If you're concerned about whether a tree is sick, a health assessment is the right starting point. If you're concerned about whether a tree could fall and cause damage, a risk assessment is what you need. Our arborists will help you determine which type of evaluation — or combination — fits your situation.
