Who we are

Arborists who treat every canopy like a signature project

We are PrecisionTreeService, a boutique-yet-scalable tree care partner rooted in Ontario, California. Our crews mix certified arborists, seasoned climbers, and spotless clean-up specialists who operate with purposeful rigging. We thrive on complex removals tucked between tight setbacks, pristine prunes over luxe pools, and preventive care plans that outthink storms before they blow in from the coast.

From the first site walk, we map load-bearing branches, lean angles, utilities, rooflines, neighboring fences, and wind corridors. That intel fuels a zero-drama game plan that keeps your family, tenants, or guests at ease while we do the heavy lifting.

The difference you see, hear, and feel

Homeowners share that we communicate in plain language, show up with clean trucks, and leave each site photo-ready. We schedule tightly, provide real-time SMS updates, and wrap with a spotless sweep so your guests return to a polished space.

Safety obsession

Every crew lead is empowered to pause the job if wind shifts or new hazards appear. Harnesses, helmets, eye pro, and drop zones are non-negotiable.

Design-forward trims

We sculpt to enhance curb appeal, frame architecture, and protect property value. Lines are intentional, proportions balanced, and cuts precise.

Transparent pricing

Clear scopes, itemized proposals, and onsite walk-throughs mean you understand the plan, the crew, and the cleanup before we ever start the saw.

Playbook

Our four-phase tree care playbook keeps projects calm and fast

01 // Assess

Walk the property, photograph risk points, map utilities, note lean, decay pockets, and canopy load. Align with your priorities: safety, aesthetics, clearance, insurance compliance.

02 // Plan

Draft rigging paths, traffic flow, chipper staging, crane pads, and contingency moves. Schedule around quiet hours, guest arrivals, or retail foot traffic.

03 // Execute

Deploy climbers, lift ops, ground crew, and clean-up leads. Control the drop zone, section timber, feed chippers, and protect lawns with mats.

04 // Restore

Rake, blow, and magnet-sweep. Backfill grind holes, spread fresh mulch rings, and share care notes for how to keep the canopy thriving.

Throughout the process, your point person shares progress texts, before/after photos, and a simple checklist so you know exactly what was completed and what to watch as the season changes.

Safety + Sustainability

We protect people, pets, property, and the planet

Jobsite control

Coned drop zones keep neighbors, guests, and kids safely outside the work area. We coordinate with HOA boards and property managers before the first cut.

Clean disposals

Logs are reclaimed, chips are repurposed for erosion control, and green waste is diverted from landfills whenever possible.

Eco-minded care

We favor selective pruning over aggressive topping, protect root zones, and recommend drought-smart watering schedules tailored to Ontario, California weather.

Respectful crew culture

Polite crews, tidy language, uniformed pros. We treat your neighbors the way we treat your treeswith respect.

Testimonials

Stories from neighbors across Ontario, California

Quiet, surgical, spotless.

They cleared three leaning pines over our guest cottages without disturbing a single walkway. Communication was constant and the cleanup looked like a housekeeping team swept through.

L. Ramirez, boutique resort GM

Design-focused pruning that framed our home.

Instead of hacking limbs, they shaped the canopy to reveal our facade. The crew lead explained every cut and even mulched the beds before leaving.

L. Chen, homeowner in Ontario, California

Lightning-fast storm response.

A limb blocked our driveway at 6am. By 8:30 the crew had it down, chipped, and the street swept. No drama, just results.

A. Patel, property manager
