Tree service in Harmony — common questions.
How fast can you respond to emergencies in Harmony?
We offer 24/7 emergency response for Harmony and all of Southern Wisconsin. Our crews are typically on-site within a few hours for urgent storm damage, fallen trees, or hazardous situations near structures. Call (608) 751-4171 any time — a real person, or our AI phone assistant, will route you immediately.
Are your arborists ISA Certified?
Yes. Every estimate in Harmony is walked by an ISA Certified Arborist — Jason James (WI-1418A) or Andrew — not a commission salesperson. We're also TCIA Accredited and carry $2 million in liability insurance plus full workers compensation on every crew.
Do you offer free estimates in Harmony?
Yes — estimates are always free. You can request one by phone at (608) 751-4171, through our online contact form, or via our AI phone assistant, which will text you a self-scheduling link within minutes so you can pick a time that works for you.
Do I need a permit to remove a tree in Harmony?
For trees on private property, most Harmony-area jurisdictions don't require permits for tree removal. Trees in the public right-of-way (the strip between sidewalk and street, or boulevard trees) are typically managed by the local public works or forestry department and require coordination before any work. Properties in historic districts, HOA-governed neighborhoods, or specific platted subdivisions may have additional restrictions. We handle all permit research and city coordination as part of our service.
Do you work on both residential and commercial properties in Harmony?
Yes. We handle single-tree removals, full property clearing, HOA and municipal maintenance contracts, and commercial snow-and-ice management. For property managers and HOAs we provide seasonal service agreements that keep trees safe and budgets predictable.
What's included in your tree removal service?
Our tree removal in Harmony includes a walk-through with an ISA Certified Arborist, full removal to ground level, optional stump grinding to 6 inches below grade, brush chipping, and complete property cleanup. We leave your yard spotless.
Do you use climbing spikes or topping cuts?
No. We follow ANSI A300 standards — no spikes on trees we're pruning (only removals), no topping cuts, and no indiscriminate pruning. Our work is designed to keep your trees healthy and structurally sound long-term.
When is the safe window to prune oak trees in Harmony?
November through March only. Oak wilt is a fatal fungal disease spread by sap beetles attracted to fresh pruning wounds during warm months. Pruning oaks in Harmony between April and October exposes wounds that beetles visit, depositing oak wilt spores that can kill the tree within weeks. We never prune oaks outside the safe dormant window unless it's an emergency hazard, in which case we apply tree wound paint immediately to seal the cut.
Can you treat ash trees for emerald ash borer in Harmony?
Yes. For valuable ash trees still healthy enough to save (less than 30% canopy decline), we perform trunk-injection treatment with emamectin benzoate (TREE-äge or Arbor-Mectin) every 2 to 3 years. The optimal injection window is mid-April through June. For ash trees with more than 50% canopy decline, removal is usually the right call — treatment can't reverse advanced damage. We give an honest tree-by-tree assessment for each ash on your property.
Do you help with storm damage insurance claims in Harmony?
Yes. We provide detailed photographic documentation, written damage assessments, and itemized invoices that adjusters need to process claims efficiently. We bill many major homeowners insurance carriers directly so you don't have to front the cost. Our documentation has helped Harmony homeowners through claims after every major storm event in the past decade — derecho damage, ice storms, summer thunderstorms, and heavy wet snow events.
