Comprehensive arborist services tailored to Thornwood properties. Click any service to learn more.
Aesthetic trimming that shapes the canopy and clears branches away from rooflines, power lines, and walkways. Our crews work with rope rigging to keep the work clean and the property undamaged.
Integrated pest management for emerald ash borer, gypsy moth, scale insects, Japanese beetles, and other tree pests. Trunk injections, soil drenches, and bark sprays — chosen for least impact.
Species-appropriate tree planting with proper root ball preparation, planting depth, soil amendment, and staking. We help you choose trees that will thrive on your specific site.
Health-focused pruning following ANSI A300 standards. Our arborists make proper cuts at the branch collar to remove weak, diseased, or crossing limbs while preserving the natural canopy structure.
Expert removal of leaning, decaying, or structurally unsound trees before they fail. Our arborists evaluate root health, trunk integrity, and lean angle to identify true hazards — then remove them safely.
Shrub and hedge trimming by crews who understand which plants tolerate hard pruning and which need a gentle touch. Formal lines on hedges, natural shape on shrubs — clean results either way.
Fast emergency tree response — we are available day, night, weekends, and holidays. Our crews assess the situation, plan a safe approach, and clear the hazard while keeping your property and people protected.
Post-storm cleanup including downed tree removal, broken-limb extraction, and complete debris hauling. We coordinate with insurance adjusters and document the damage as needed.
Professional lot clearing service from small overgrown sites to multi-acre projects. We handle tree removal, brush clearing, chipping, and final grading — leaving you a build-ready site.
Professional crown thinning that improves tree health and reduces storm damage risk. We remove select branches throughout the canopy — never lion-tailing, never over-thinning that causes stress.
Structural cabling and bracing to support weak unions and split trunks on otherwise healthy trees. Properly installed ANSI A300 hardware can extend a heritage tree life by decades.
Full-service tree takedowns from initial assessment through final cleanup. Our arborists handle everything — rigging the canopy down piece by piece, removing the trunk, grinding the stump, and clearing all debris.
Whole-tree size reduction to reduce wind sail, fit the site better, or clear setbacks. Our arborists make proper reduction cuts at lateral branches — never topping, never lion-tailing.
Targeted removal of dead, dying, and broken branches throughout the canopy. Eliminates falling-limb hazards, reduces disease pathways, and improves overall tree health and appearance.
Skilled removal of standing deadwood, regardless of size. We use the right combination of climbing, rigging, and crane support for each dead tree to keep our crew and your property completely safe.
Mechanical and hand-dug tree transplanting for trees up to large caliper sizes. We root-prune in advance when possible, lift with proper soil mass, and re-plant with deep watering protocols.
Selective canopy planing to level uneven growth and refine tree silhouettes. We work with the natural tree form rather than against it, balancing aesthetics with long-term tree health.
Professional tree fertilization that delivers nutrients where roots can actually use them. Surface fertilizer feeds the lawn — deep-root injection feeds the tree. Real plant health care, not just spreading granules.
Independent expert opinion from ISA-trained arborists — risk assessments, hazard tree reports, plan reviews, and pre-construction tree protection plans for legal, insurance, or HOA needs.
Complete stump extraction beyond what grinding can offer. Our crews dig out the root ball with appropriate equipment, dispose of the wood, and leave the site ready for the next phase of construction or landscaping.
Cost-effective stump grinding that takes the visible stump 6 to 12 inches below grade. Fast and efficient — ideal when you need to mow, replant grass, or simply get rid of the eyesore.
Effective tree disease treatment that targets the actual pathogen — not generic spray-and-pray approaches. We diagnose first, treat appropriately, and avoid unnecessary chemical applications.

Have questions about tree care in Thornwood? We have answers.
For most species in Thornwood, late winter through early spring (while trees are dormant and before bud break) is the ideal pruning window — wounds heal cleanly and disease pressure is lowest. Oaks should not be pruned during the spring-summer oak wilt risk period. Storm damage and hazardous limbs can be addressed any time of year. We tailor pruning timing to each species at your Thornwood property.
Tree removal permits in Thornwood depend on local ordinances, the tree species, the trunk diameter, and whether the tree is on private property or in the public right-of-way. Some New York municipalities protect heritage trees, certain native species, or street trees, while others require no permit for private-property removals. We check local rules before quoting and pull permits on your behalf when required.
Warning signs in Thornwood trees include large dead branches, mushrooms or conks at the base (indicating root rot), bark falling off in sheets, hollow trunk cavities, sudden lean, recent root disturbance, and crown dieback. A live tree may still be hazardous due to structural defects. Our arborists can perform a paid risk assessment with a written report, or include a basic visual evaluation with any free quote.
Yes. Our crews working in Thornwood include ISA-trained arborists who follow ANSI A300 pruning standards and ANSI Z133 safety standards. ISA-certified credentials are individual and may vary by team member, but every crew leader on a Thornwood job has the training to assess tree health, plan rigging properly, and make pruning cuts that promote long-term tree vitality rather than damaging the tree.
Tree removal in Thornwood means taking the entire tree down to a stump or grinding the stump as well — usually because the tree is dead, hazardous, undesirable, or in the way of construction. Tree trimming is selective branch work to shape the canopy, clear structures, or improve appearance. Pruning is more health-focused than trimming, removing weak or diseased wood. We help Thornwood property owners decide which approach fits each tree.
In most New York jurisdictions, Thornwood property owners have the legal right to trim neighbor branches that cross the property line, but only up to the property line and only without damaging the tree health. We always recommend a friendly conversation with the neighbor first and proper documentation. B. Haney and Sons Arborists can perform the work and provide written records — but the legal questions belong with you, not us.
Real reviews from property owners we have served across the country.
"Tree planting service was excellent. The arborist helped us pick species that would thrive in our soil and climate, and the planting itself was done with proper depth, root ball preparation, and staking. All five trees are doing great two seasons later."
"I have been using B. Haney for our property for years. They prune our maples every other winter and the trees have never looked healthier. There is something to be said for hiring an arborist company that has been doing this since 1940 — the experience shows in every cut."
"Deadwooding on a large oak in our front yard. The arborist climbed up and removed every dead branch he could find — no broken limbs falling on us during storms now. Tree looks healthier and the canopy is more open. Excellent work."
