Tree Service in Glendora, CA
Many trees in the Pride of the Foothills grow on slopes below the mountains. Our crews trim and remove trees on your lot, and a good tree service in Glendora tells you when the City Forester must approve first.
Tree care in Glendora
Foothill homes, old groves and a famous vine
No one may trim, top or remove a Glendora City tree without the City Forester's approval. The city looks after about 16,000 of them on a grid schedule. George Whitcomb founded the town in 1887 and named it partly for his wife, Leadora. Citrus once covered more than 5,000 acres here. The Glendora Bougainvillea, planted in 1901, now runs 600 feet down both Bennett and Minnesota Avenues. In January 2014 the Colby Fire burned 1,952 acres in the hills above town and destroyed five homes. Mud from the burn area later flowed down in heavy rain.
In Glendora, the first question about a parkway tree is simple: has the City Forester said yes?

Who governs tree work in Glendora
City of Glendora
Tree work in Glendora follows the City of Glendora's rules. No one may trim, top or remove a City tree without prior approval from the City Forester, though a property owner who gets that permission may trim or remove an approved parkway tree next to their property. A removal inspection costs $520 and may be refunded if the tree meets the removal criteria in the Tree Preservation Ordinance (Municipal Code Section 16.14), and the owner must pay the full cost of a replacement if the tree is removed or damaged during trimming. Rules change. Confirm current requirements with the jurisdiction before work begins — filing a permit is the property owner's responsibility, not ours.

What we handle
Tall palms, big crowns and removals below Glendora's foothills
Supreme Tree Experts trims tall palms, lowers crowns and removes trees on Glendora lots, where some palms reach 94 feet. Whether a tree is yours or the City Forester's, Glendora owners can start by asking Supreme Tree Experts.
Tree Removal

Our crews fell trees on your own Glendora lot, lowering the pieces by rope. A City tree comes out only after a $520 removal inspection, refunded if it meets the ordinance. Leaves and fixable hardscape damage do not qualify.
Tree Trimming & Pruning

Our crews thin and shorten your own trees with proper cuts and no topping. Trimming a City tree takes the City Forester's approval. If a City tree is damaged during that work, the owner pays for a replacement.
Stump Grinding & Stump Removal

We grind stumps below grade so the ground can take new planting. Slope, street access and whether a tree is yours or the city's shape much of the price here. We grind wide enough to clear the main roots.
Palm Tree Trimming & Skinning

Before dry winds bring them down, we cut dead fronds and seed stalks from tall palms. Our crew then skins the old frond bases for a smooth trunk. All of it runs from our lift truck for palms.
Emergency Tree Service

Call our crews 24/7 when a tree hits your roof or blocks the drive. Dry winds, heavy rain on burned hills and tall old trees can put homes here at risk. We clear the danger first.
Tree Maintenance

We give private trees here their own check each year for weak limbs and decay. The city trims its roughly 16,000 trees on a grid schedule, area by area. Yours are not on that grid.
Tree Height Reduction

Our crews lower tall crowns to strong side branches and never top them. On lots below the foothills, height reduction takes weight off the upper limbs that catch gusts off the slopes. The tree keeps a natural outline after each cut.
Estate Tree Care

We give larger hillside lots a yearly plan covering pruning, dead wood and clearance. The 2014 Colby Fire burned 1,952 acres in the hills above town and destroyed five homes. We keep dead wood cleared near the house.
Tree Shaping & Shrub Shearing

We shear hedges and cut back fast vines like bougainvillea. Glendora's famous one, planted in 1901, now runs 600 feet down both sides of two avenues. A home vine needs regular cuts to stay off eaves, gutters and roof tiles.
Landscaping

We plan planting for yards that climb from the valley floor toward the mountains. Deep-rooted shrubs and ground cover help hold a sloped bed in place. We fit each plant to the sun, water and space you have.
Hardscape

We build walls and paths on slopes with drainage in mind. In November 2014, a debris flow from the burn area left about four feet of mud against one home. Keeping drains clear before storms matters here.
Glendora tree questions, answered
Start here — these 6 cover most of what you need before booking tree work in Glendora. If yours is not here, call 877-787-7363 and ask.
Only with the City Forester's approval. Glendora bans unauthorized trimming, topping or removal of City trees. With permission, an owner may trim an approved parkway tree. If the tree is damaged or removed during that work, the owner pays the full cost to replace it.
No. Leaves, wildlife, root damage to lines, or hardscape damage that can be fixed without losing the tree are not reasons the city accepts. A removal inspection checks the tree against the Tree Preservation Ordinance, and the fee may be refunded if the tree qualifies.
On a grid schedule. Public Works staff or contract Certified Arborists trim City trees area by area, following ISA pruning methods. You can file a Tree Service Request Form for an out-of-grid inspection or trim, a new tree, or a removal.
Burned slopes can shed mud in heavy rain. The 2014 Colby Fire burned hills that had not burned much since the 1960s. That November, a debris flow left about four feet of mud against the back of a home on Easley Canyon Road. Keep drains and paths clear before storms.
Yes — $600 for tree services, wherever the job is. Slope, access from the street and whether a tree is yours or the city's shape much of the price here.
Yes, 24/7. Dry winds, heavy rain on burned hills and tall old trees can all put Glendora homes at risk at odd hours. Call 877-787-7363.

Glendora's canyon-side lots, and the family crew equipped to work them
Tree work goes wrong when it is rushed or under-equipped. We run our own 75-foot boom trucks, lift trucks, chippers and stump grinders, and every crew works under an ISA Certified Arborist — so the job gets done right the first time.
We hold California license #1002853 for both landscaping and tree and palm work, we are bonded, we carry general liability and every employee is on workers’ compensation.

ISA Certified Arborist
The free arborist visit settles whose tree it is. About 16,000 trees belong to the city, and none may be trimmed without the City Forester's approval.
Licensed, Bonded & Insured
City trees need approval; yours need a licensed crew. Ours holds #1002853 in both C-61/D-49 and C-27, is bonded and insures each Glendora worker.
Southern California Since 1985
Our family business dates to 1985 — young beside a bougainvillea planted here in 1901, but long enough to know old plants need patience.
Our Own Equipment
Canyon-side lots with big crowns suit our 75-foot boom trucks and lift truck, and our chippers haul limbs off the same day.
