Expert arborist services for homes and businesses across Mercer Island, WA. ISA-trained, fully insured, ready 24/7.
From routine pruning to emergency tree response, we handle every tree care need for homes and businesses in Mercer Island, WA.
Complete tree removal with bucket truck, crane, or rope-rigging methods chosen to fit the site. We protect surrounding structures, fences, and gardens — then haul wood and grind the stump for a clean finish.
Complete deadwood removal from large mature trees. Our climbers go through the canopy systematically, identifying and removing every dead branch worth taking — safer trees, healthier appearance.
Professional tree pest control using IPM principles. We identify the pest, choose the most targeted treatment method, and protect non-target pollinators wherever possible — effective and responsible.
Complete lot clearing with the right equipment for the scale — track loaders, chippers, brush mulchers, and chainsaw crews. Fast, efficient, and priced per acre rather than per tree.
Professional cabling and bracing for valuable trees with structural weaknesses. We use rust-resistant cable, proper hardware, and ANSI A300 installation methods to give your tree decades more life.
Professional tree planing that reshapes overgrown or unbalanced canopies for residential and commercial landscapes. Our arborists never lion-tail or top — only proper reduction cuts that the tree can recover from.
24/7 emergency response for trees on houses, blocking driveways, or hanging dangerously after storms. Our crews mobilize fast with cranes, bucket trucks, and chainsaws to make your property safe.
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.
Careful removal of dangerous trees that threaten your property or your family safety. Our crews use crane support, controlled rigging, and ANSI Z133 safety standards on every hazardous tree job.
Professional tree transplanting that maximizes establishment success. Our crews assess the tree, plan the move, and handle the lift, transport, and replanting with the care a heritage tree deserves.
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.
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.
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.
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.
Careful tree pruning by ISA-trained arborists. We never top, lion-tail, or stub-cut — every cut is made with the tree biological response in mind, protecting the heartwood and accelerating wound closure.
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.
Specialized takedown of dead trees that have become brittle and unpredictable. We use crane assistance and advanced rigging because deadwood does not behave like live wood under load — safety-first work.
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.
Professional arborist consultation services with written reports. Whether you need a tree risk assessment, a real estate transaction document, or a construction tree protection plan, we provide credible expert opinions.
Custom tree fertilization programs based on soil testing and species needs. Our arborists prescribe and apply slow-release nutrients via deep-root injection — restoring vigor that surface feeding cannot match.
Targeted treatment for oak wilt, anthracnose, Dutch elm disease, apple scab, and other tree pathogens. We diagnose accurately and apply EPA-registered fungicides only when they will actually help.
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.

Answers to the most frequently asked tree service questions from Mercer Island property owners.
Warning signs in Mercer Island 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. Standard B. Haney and Sons Arborists tree work in Mercer Island 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.
Tree removal costs in Mercer Island typically range from $400 to $1,800 for standard residential trees and $2,000 to $6,000 or more for very large trees, hazardous trees over structures, or trees requiring crane assistance. Pricing depends on tree size, species, location relative to buildings and power lines, and whether stump removal is included. We provide free on-site estimates with detailed, written quotes before any work begins.
We provide 24/7 emergency tree response throughout Mercer Island and surrounding Washington 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.

For most species in Mercer Island, 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 Mercer Island property.
Yes. Our crews working in Mercer Island 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 Mercer Island 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.
Our reputation is built on results. Here is what our customers say.
"Tree fertilization and deep-root feeding program for our older trees. The arborist tested the soil first, prescribed a custom blend, and applied it properly into the root zone. Trees are noticeably more vigorous this growing season. Worth it."
"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."
"Solid tree service experience. Two trees removed, two pruned, all stumps ground. Work was professional and the cleanup was good. The estimate-to-schedule timeline was longer than I expected but the actual day-of work was efficient and well-executed."
