Professional tree care, pruning, removal & emergency response serving San Luis Obispo and surrounding communities in California.
Every tree service you need, delivered by trained arborists who know the San Luis Obispo area.
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.
Deep-root fertilization and plant health care designed for established trees in compacted urban soils. We test, prescribe, and inject custom slow-release nutrients into the root zone.
Professional tree installation by arborists who know what they are doing — proper depth, mulch ring, watering instructions, and species selection that matches your soil, sun, and space.
Full root-ball stump removal for new construction, foundation clearance, or anywhere the entire root mass must come out. We excavate the stump completely, back-fill, and grade the area.
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 storm cleanup from broken limbs to whole-tree removals. We work fast after weather events to clear hazards, haul wood and debris, and leave your property safe and accessible again.
Safe, professional removal of unwanted, oversized, or dying trees. Our certified arborists assess each tree, plan the rigging carefully, and bring it down in controlled sections without damaging structures or landscaping.
Acreage clearing for new construction, agricultural conversion, view corridors, and fire-break creation. Our heavy-equipment crews drop, chip, and haul efficiently at competitive per-acre pricing.
Skilled trimming work that balances appearance with tree health. Our arborists know which branches to remove for clearance and which to leave for canopy structure — every cut is intentional.
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.
Tree pest treatment by arborists who understand insect biology. From emerald ash borer trunk injections to scale soil drenches, we choose the right method, the right timing, and the right product.
Tree planing service for property owners who want refined silhouettes without compromising tree structure. We make selective cuts that improve appearance and preserve the tree long-term health.
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.
Selective branch removal to increase light and air movement through the canopy without reducing overall size. Reduces wind resistance, improves understory growth, keeps natural tree shape.
Professional deadwooding service that removes only the dead branches — leaving live structure untouched. Climbed work with careful spotting to ensure no live wood is removed by mistake.
Professional stump removal by grinding. We bring the right-sized grinder for the access (handheld for tight spots, track-mounted for big stumps), grind the stump and surface roots, and rake the chips smooth.
Crown reduction service done right — proportional canopy reduction that respects tree biology. Our certified arborists size up each cut to ensure the tree heals cleanly and continues to thrive.
Professional pruning that improves tree health, structure, and longevity. We selectively remove problem branches, reduce wind sail where appropriate, and leave the tree balanced and ready to thrive for years.
Tree cabling and bracing services by ISA-trained arborists. We assess the structural defect, design appropriate hardware placement, and install cables that prevent tree failure without strangling growth.
Professional dead tree removal with proper safety protocols. Dead trees are more dangerous than they look — our arborists know how to assess wood integrity and bring them down in controlled sections.
Tree relocation service for valuable specimens that need to move within or between properties. We use spade trucks, hand-dug methods, and proper aftercare to give your transplanted tree the best chance.
Professional shrub and hedge maintenance — formal hedges, foundation plantings, and overgrown ornamentals. We shape with the right tool for each species and the proper timing.

Answers to the most frequently asked tree service questions from San Luis Obispo property owners.
Warning signs in San Luis Obispo 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.
We provide 24/7 emergency tree response throughout San Luis Obispo and surrounding California communities. For trees on houses, blocking driveways, or hanging dangerously after storms, our crews typically arrive on-site within 1 to 4 hours of your call depending on weather conditions and current call volume. We arrive with chainsaws, rigging gear, and bucket-truck or crane support as the situation requires.
Absolutely. Tree work is high-risk by nature, and any contractor cutting trees on your San Luis Obispo property should carry general liability insurance and workers compensation coverage. B. Haney and Sons Arborists maintains both, and we will provide certificates of insurance on request before starting work. Hiring uninsured tree cutters is one of the most common ways San Luis Obispo property owners end up with serious financial liability.
For most species in San Luis Obispo, 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 San Luis Obispo property.
Yes. Standard B. Haney and Sons Arborists tree work in San Luis Obispo includes hauling the limbs and brush off the property, chipping the small wood, and grinding the stump if requested. Larger trunk wood is cut to manageable lengths and either hauled away or left as firewood at your direction — your choice, no extra charge either way. We rake and clean the work site so it looks better than when we arrived.
Yes. Our crews working in San Luis Obispo 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 San Luis Obispo 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.

"Good experience overall with B. Haney and Sons. They pruned our front-yard oak and trimmed back the maples that were rubbing on the roof. Office took a couple of follow-ups to schedule, but the field crew was top-notch and the work was done right. Trees look great."
"Hazardous tree removal on a leaning oak threatening our house. Crew arrived on time with proper equipment, rigged everything down in sections, and the property was completely safe the entire time. Great communication from quote through cleanup."
"Good quality tree work. Pruning was done well and the trees look great. Office communication was a little slow at the start, but once the crew was on-site everything went smoothly. Reasonable pricing too."
