Mt. Lebanon, Pennsylvania occupies 6.2 square miles of Pittsburgh’s South Hills where the tree canopy is not just landscape. It is identity. Streetcar service arrived in 1901, and the real estate subdivisions that followed planted shade trees on every new lot. The Liberty Tunnels opened in 1924 and doubled the population within a decade. By 1930, the street trees that define Mt. Lebanon today were already in the ground.
That London plane tree on Washington Road with a girdling root buckling the brick sidewalk has been growing since the first subdivision went in. The white oak in Virginia Manor still has a cable system that has not been inspected in 15 years. The Norway spruce in the Hoodridge section is losing needles from the inside out, and the browning is accelerating every season.
Mt. Lebanon’s canopy is 90 to 120 years old in the earliest neighborhoods. It sits on dense streetcar-era lots where structures are eight feet from trunk lines. And beneath all of it, abandoned coal mines from the 1883 to 1923 mining era create subsurface voids that quietly undermine root stability across the township.
Horhut Tree Experts has worked Mt. Lebanon and the South Hills for over three decades. We understand that tree work in a National Register Historic District with 3,341 contributing buildings requires precision, preservation instinct, and respect for what this canopy means to this community.

Residential & Commercial Tree Services
Mt. Lebanon’s mix of dense residential streets and the Washington Road commercial corridor creates two distinct sets of tree care demands. Residential lots in neighborhoods like Seminole Hills, Sunset Hills, and Clearview carry mature hardwoods on setbacks that predate modern building codes. Trees planted 90 years ago sit closer to foundations, siding, and rooflines than any arborist would recommend today. Commercial properties along Washington Road and Beverly Road deal with street trees, parking lot islands, and canopy that overhangs storefronts and pedestrian traffic.
Our ISA Certified Arborists serve both contexts. Residential work in Mt. Lebanon requires low-impact techniques that protect adjacent structures, sidewalks, and neighboring trees on lots where there is no clear drop zone. Commercial work demands scheduling that minimizes disruption to foot traffic and business operations, with cleanup standards that match the community’s expectations.
Whether the job is a heritage oak behind a Tudor Revival on Bower Hill Road or a row of ornamental pears along a retail frontage, the approach is built around the specific conditions of the site. Call 412-855-2703 to discuss your property.
Tree Removal
Tree removal in Mt. Lebanon means working on some of the tightest residential lots in the South Hills. The streetcar-era subdivision layout puts houses, garages, driveways, and sidewalks in close proximity to every mature tree. A silver maple with a 60-foot canopy spread may have targets in every direction: the owner’s roof to the east, a neighbor’s fence to the west, a utility line overhead, and a brick retaining wall at the base.
Our arborists assess internal decay, root plate integrity, lean mechanics, and the full target envelope before recommending removal. In Mt. Lebanon, sectional dismantling with rigging control is the standard method. Trees come down in pieces, each one lowered to a specific landing zone. On the steeper lots in the McNeilly and Lebanon Hills sections, crane-assisted removal keeps weight off slopes already challenged by the township’s clay soils and legacy mine subsidence.
Every removal includes stump grinding below grade, debris hauling, and restoration of the immediate work area. Permits and utility coordination are handled before the crew arrives.

Tree Trimming & Pruning
The canopy that makes Mt. Lebanon’s streets iconic also creates structural liabilities that worsen with every year of deferred maintenance. Co-dominant stems in century-old maples carry equal weight on both sides of a union that was never corrected. Interior deadwood accumulates in canopies too dense for light to penetrate. Lower limbs press against slate roofs, copper gutters, and century-old masonry that cannot absorb impact without damage.
Our arborists prune to ANSI A300 standards using species-specific protocols. For the oaks concentrated in the Virginia Manor and Mission Hills neighborhoods, dormant-season structural work reduces weight on overextended limbs while preserving the canopy profile that defines these streets. For the maples along Cedar Boulevard and Cochran Road, crown cleaning eliminates the deadwood and crossing branches that cause progressive interior decline.
Clearance pruning maintains safe distances from siding, rooflines, and overhead utilities. Vista pruning restores sightlines at intersections and driveway exits where overgrown canopy blocks visibility along narrow streets.
In a community where the streetscape character depends on its trees, pruning is preservation. Neglect is the threat.

Tree Planting
Mt. Lebanon is losing irreplaceable canopy. Trees planted during the streetcar and Liberty Tunnel eras are reaching the end of their structural life spans, and every removal without a strategic replacement thins the township’s defining feature. The question is not whether to replant. The question is what to plant and where.
Our arborists evaluate each planting site for soil conditions, drainage, sun exposure, mature canopy spread, and proximity to structures and utilities. Mt. Lebanon’s clay soils and coal-era subsurface disturbance complicate root establishment in ways that standard nursery advice does not address. A tree that thrives in amended garden soil may fail in the compacted, mineral-depleted clay that underlies most of this township.
For the narrow tree lawns along residential streets, we select columnar and upright cultivars that provide canopy without crowding facades. For the larger lots in Parker Gardens and Woodridge, we match species to the specific slope, aspect, and drainage pattern of each planting position.
Root flare exposure, structural soil amendments, and three-year establishment monitoring come standard. The goal is a tree that serves the property for the next century, not just the next decade.
Replace what the township is losing with species that belong here: 412-855-2703 or get a planting consultation.
Pest and Disease Control
Mt. Lebanon’s aging canopy is a target-rich environment for pests and pathogens. Emerald ash borer has already claimed most untreated ash across the township. Spongy moth outbreaks defoliate the oaks on exposed lots along the ridgelines. Bacterial leaf scorch is spreading through the pin oak and red oak populations, causing progressive dieback that mimics drought stress but does not respond to watering. Anthracnose hits the dogwoods and sycamores during wet springs, and the township’s valley-bottom neighborhoods stay damp enough to sustain infection cycles well into June.
Our diagnostic process identifies the specific organism or stressor before any treatment begins. Trunk injection delivers systemic insecticides and fungicides directly into the vascular tissue for emerald ash borer prevention, hemlock woolly adelgid suppression, and bacterial leaf scorch management. Soil-applied treatments correct pH imbalances and nutrient deficiencies in the acidic clay soils common across Mt. Lebanon.
For the ornamental plantings along Washington Road and the residential specimen trees in Highland Terrace and Avondale, we design monitoring schedules that catch infestations at the earliest treatable stage. Reactive treatment after visible damage appears costs more and saves less.
Stop the spread before it jumps to the next tree: 412-855-2703 or schedule a pest evaluation.
Tree Care and Maintenance
Sustained maintenance is what separates a tree that serves a property for 100 years from one that becomes a liability at 60. In Mt. Lebanon, where the original canopy is already pushing those numbers, the margin for neglect is gone.
Our maintenance programs include annual inspections, soil testing, targeted fertilization, and structural assessments calibrated to each tree’s species, age, and site conditions. For the mature oaks and maples that anchor the older neighborhoods along Shady Drive East, Terrace Drive, and Kelso Road, root zone decompaction restores oxygen exchange in soils compressed by decades of foot traffic, grade changes, and turf maintenance.
Mulching protocols follow the two-to-four-inch depth standard with proper clearance from the root flare. The mulch volcanoes piled against trunks across the township are slowly killing trees by trapping moisture against bark and encouraging adventitious rooting above the natural root crown.
We build multi-year care plans that account for the specific decline trajectory of each species. What an oak needs at 80 years is different from what it needed at 40. Generic annual treatments applied without diagnostic context waste money and miss the actual problems.

Tree Support System
Mt. Lebanon’s oldest trees carry structural compromises that developed over decades. Co-dominant stems that were never subordinated have grown into massive forks supporting thousands of pounds on each side. A single ice storm or wind event can split that union and drop half the canopy onto a roof, a car, or a pedestrian sidewalk.
Cable and brace systems redistribute mechanical stress across these weak points without requiring removal. High-strength steel cables installed in the upper canopy limit the range of motion between co-dominant stems, reducing the leverage that causes splitting. Through-bolts and threaded rods reinforce unions with included bark where the structural wood has failed to fuse.
Our arborists assess each candidate for support viability. Not every compromised tree is a support candidate. If internal decay has progressed past the point where hardware can carry the load, removal is the honest recommendation. But for structurally sound trees with correctable geometry, supplemental support extends productive life by decades at a fraction of the replacement cost.
Support systems require periodic inspection and hardware adjustment as the tree grows. We schedule follow-up assessments on every installation.

Lightning Protection Systems
Mt. Lebanon’s tallest trees sit on ridgeline lots that take direct electrical strikes during summer storms. A lightning hit can explode bark, shatter cambium layers, and kill a mature hardwood in a single event. On the dense lots in this township, a struck tree can also ignite adjacent structures, damage underground utilities, and scatter debris across multiple properties.
Copper conductor systems installed from the canopy crown to a ground rod network provide a low-resistance path that routes electrical energy safely into the soil. The tree survives. The surrounding structures stay protected. The investment in a century of growth is preserved.
Our installations follow ANSI A300 Part 4 standards for lightning protection. Conductor routing accounts for the tree’s growth pattern, bark thickness, and branch architecture to maintain effectiveness as the canopy expands. Ground rod placement factors in Mt. Lebanon’s clay soils and potential subsurface anomalies from the township’s coal mining history.
Lightning protection is particularly warranted for specimen trees that anchor estate lots, provide critical shade to south-facing facades, or sit within strike distance of occupied structures.

Storm Damage Cleanup
Summer microbursts and winter ice storms hit the South Hills hard. Mt. Lebanon’s dense canopy catches wind and ice load that open lots shed. When a mature tree fails on a streetcar-era lot, the damage radius covers the owner’s house, the neighbor’s garage, the sidewalk, the street, and the utility lines overhead.
Our emergency crews deploy within hours. Priority goes to trees on structures, trees on power lines and roadways, and hanging limbs that could release at any moment. Every response starts with a hazard assessment. A tree that lost one major limb may have a compromised root plate or a hidden trunk crack that makes the remaining structure unstable.
Insurance documentation is standard. Timestamped photos, detailed scope of work, and direct adjuster coordination at 412-855-2703. Most homeowner policies cover storm-related tree damage when structures are involved.
Post-storm evaluation identifies secondary risks. Trees stressed by one event fail at higher rates during the next. We flag compromised trees on your property and adjacent lots before the next system rolls through the South Hills.

Expert Tree Maintenance Services
Beyond individual tree care, Mt. Lebanon properties benefit from comprehensive landscape-level tree management. A property with 8 or 12 trees across the front yard, side yard, and rear lot line needs a coordinated plan, not piecemeal service calls.
Our arborists develop property-wide maintenance programs that prioritize work by urgency, season, and budget. Structural pruning on the high-risk oak goes first. Deadwood removal on the ornamentals happens in the same visit. Soil treatments and pest monitoring run on scheduled intervals timed to the biological cycles of the target organisms.
This approach catches problems that single-tree assessments miss. A fungal infection on one tree may indicate a soil condition affecting every tree on the lot. A pest infestation in the backyard canopy may be advancing toward the front-yard specimens. Coordinated management connects the dots.
For properties in Mt. Lebanon’s historic neighborhoods where the tree canopy predates the houses, landscape-level management is not a premium service. It is the baseline for responsible ownership.
