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.
Anybody can call themselves an arborist — there’s nothing stopping them. But an ISA-certified arborist? That’s earned, not just claimed. It takes years of real-world experience, a demanding and detailed exam, and a steady commitment to ongoing education to keep that credential.
That’s exactly why it matters so much to homeowners, property managers, and municipal staff. It cuts right through the noise and separates your average tree-care worker from someone who genuinely knows what they’re doing. And when you consider how much value trees add to a property — and the real risks they can pose when something goes wrong — having that level of expertise on your side isn’t just nice to have. It’s worth a lot.
Our certified arborists offer a wide range of services across the Annandale, 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.
Dealing with a fallen tree or worried about potential storm damage? We’re here to help—offering 24/7 emergency tree services to keep your property safe!
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.
Getting started is easy; you can set up a consultation via phone, email, or our online booking form linked below.
One of our ISA-certified arborists or environmental technicians will take the time to listen carefully to each question or concern.

We’re committed to providing long-lasting environmental solutions, we’ll always outline the steps to continue support.
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.
On top of having a team certified by the International Society of Arboriculture, RTEC Treecare was the first tree-care company in Virginia to earn accreditation from the Tree Care Industry Association (TCIA) — and we’re proud of that distinction.
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.
Tree work done the wrong way can wreak havoc on your landscape, hardscape, and structures. We make sure that doesn’t happen. Our zero-impact techniques — advanced rigging systems, ground protection mats, and cranes when the job calls for it — keep your property protected from the first cut to the final cleanup.
To provide the kind of award-winning tree care our clients expect, we maintain the professional-grade tools and equipment needed to get the job done properly. And that applies to all of the gear we use, from simple hand pruners and hard hats to cutting-edge diagnostic tools and aerial lifts.
For more than 30 years, RTEC Treecare has been the go-to choice for homeowners, commercial property managers, and municipalities across Annandale, VA. Over that time, our arborists have tackled just about every tree-care challenge you can think of.
