Tree work is one of the most dangerous jobs around a home, and the damage from a bad job (a limb through the roof, an injured worker, a topped tree that dies) can cost far more than the tree. Here is how to choose well. For a quick legal check of a specific quote, use our free tree license checker.

Step 1: Check the license (5 minutes, free)
In California, anyone who does a home improvement job worth $1,000 or more (labor and materials together), or any job that needs a building permit, or uses employees, must hold an active license from the Contractors State License Board (CSLB). The smaller-job exemption rose from $500 to $1,000 on January 1, 2025.
- Ask for the license number in writing. Licensed contractors must put it on their bids, contracts, and ads.
- Look it up free at CSLB's Check a License page.
- Confirm three things: the status is active, the business name and address match your quote, and the classification fits the work. Tree work is the CSLB C-49 Tree and Palm class. Companies licensed before 2024 may hold the older D-49 Tree Service class instead.
- On the same page, look at the bond (required to stay licensed), workers' compensation (a policy on file, or an exemption that means "no employees"), and any disciplinary or legal actions.
A company that arrives with a crew but shows a workers' comp exemption is a red flag: if an uninsured worker gets hurt on your property, you can be pulled into it.
Step 2: Ask for insurance in writing
A CSLB license is not insurance. Ask for a certificate of general liability insurance that names the business on your quote, and check the dates. If anything looks off, call the insurer listed on the certificate. Liability insurance covers damage to your home or a neighbor's property; workers' comp covers the crew. You want both when more than one person is on the job.
Step 3: Get 3 written, itemized quotes
Ask at least three companies to quote the same scope so you compare like with like. A useful quote lists:
- Every item of work, with materials named by brand, model, or grade where it matters
- Who pulls and pays for permits, and whether inspection fees are included
- Demolition, haul-away, and cleanup
- Start date, expected finish date, and what can cause delays
- A payment schedule tied to finished stages of work
- Warranty terms in writing
A much lower bid usually means something is missing. Ask each company what is not included.
Published national ranges (HomeGuide): removal about $200–$500 for trees under 30 feet, $500–$1,500 for 30–60 feet, $850–$2,000 for 60–80 feet; palms about $100–$1,500 by height; stump grinding about $120–$400 for the first stump. Access, lean, power lines, and crane work raise prices. Estimates only; see our tree cost estimator and full cost guide.
Make sure each quote says whether stump grinding, log and chip haul-away, and cleanup are included. These are the most common surprise charges.
Permits
Most trimming and removal on private property doesn’t need a permit, but some trees do: street trees in the public right-of-way, trees protected by a city ordinance, and trees in some HOA or habitat areas. Ask your city before removing a large or street-side tree, and put permit responsibility in the contract. Never let anyone but a qualified line-clearance crew work near power lines; call SDG&E for trees touching lines.
The contract and payments: California rules that protect you
- Down payment: no more than 10% of the contract price or $1,000, whichever is less (CSLB).
- Pay as work is done. Pay only for work that's completed, never ahead of it.
- Right to cancel: for many home improvement contracts you have 3 business days to cancel, and 5 business days if you're 65 or older (CSLB homeowner checklist).
- Changes in writing, signed before the extra work starts.
- Liens: your contract should include the "Notice to Owner" about mechanics liens. An unpaid supplier or sub can file a lien even if you paid the contractor, so ask for lien releases as you pay.
- Don't pay in cash, and keep a job file with the contract, receipts, photos, and warranties.
Warranties
Tree work rarely comes with a long warranty, so the written scope is your protection: the exact trees, how much will be cut (for pruning, ask them to follow ANSI A300 pruning standards), and what happens to the debris. Ask what they will do if they damage a fence, roof, or sprinkler line, and make sure their liability insurance covers it.
How to read reviews
- Read the 1- and 2-star reviews first, then how the owner replied. A calm, specific reply that fixes the problem is a good sign.
- Look for recent reviews describing jobs like yours in your part of the county.
- Be wary of a sudden burst of short 5-star reviews with no details.
- Ask for 2 or 3 recent customers you can call, or finished jobs you can drive by.
- Reviews tell you about service. They don't replace the license and insurance check.
Questions to ask before you sign
- How long have you been licensed under this business name?
- Who will be on site: your employees or subcontractors? Are subs licensed and insured?
- Who pulls the permit, and is the inspection fee in the price?
- What is not included in this quote?
- What warranty do you give on labor, in writing, and for how long?
- How are change orders priced if you find a problem after you start?
- Is there an ISA Certified Arborist on staff, and can I see the credential number?
- How will you protect my roof, fence, and lawn during removal?
- Do you follow ANSI A300 pruning standards (no topping)?
Red flags
- No license number, or a number that belongs to a different business name
- A big deposit, or pressure to pay in cash
- "Today only" pricing or door-to-door offers after a storm or fire
- No written contract, or one that is vague about materials and dates
- Asking you to pull the permit as the "owner-builder" (that makes you responsible)
- Payments that run ahead of the work
- Offering to "top" a healthy tree to make it smaller
- Climbing with spikes on a tree that is only being pruned (it wounds the tree)
Questions
How do I check a tree service license in California?
Ask for the license number and search it free on the CSLB Check a License page at cslb.ca.gov. Make sure the status is active, the business name matches your quote, and the classification (C-49 Tree and Palm) fits the work. The same page shows bond, workers’ compensation, and any disciplinary actions.
How much deposit can a tree service ask for in California?
For most home improvement contracts, no more than 10% of the contract price or $1,000, whichever is less, according to CSLB. After that, pay only for work that is finished.
Do I need a licensed contractor for a small job?
Since January 1, 2025, California’s minor-work exemption covers jobs under $1,000 including labor and materials, and only if no building permit is needed and the person has no employees. Anything else needs a CSLB license.
Can I cancel a home improvement contract after signing?
Often yes. CSLB says a 3-day right to cancel applies to many home improvement contracts, and a 5-day right applies if you are 65 or older. Check whether it applies before work starts.
Is an ISA Certified Arborist the same as a licensed tree contractor?
No. ISA certification shows training in tree care; a CSLB license is the legal permission to contract for the work. Good companies often have both. You can verify an arborist credential on the ISA website.
