15 Questions to Ask Before Hiring a Landscaping Contractor

Why a Structured Vetting Process Matters

Landscaping projects involve multiple trades—excavation, irrigation, planting, hardscape installation, and sometimes electrical work. Because each step depends on the previous one, a single misstep can cascade into extra labor, re‑work, or even code violations. A disciplined questionnaire forces contractors to be transparent, and it gives you a documented trail you can refer to if something goes wrong.

1. Verify Licensing and Certifications

Not all states require a landscaping license, but many jurisdictions do for specific trades (e.g., irrigation, grading, or tree work). Even when a license isn’t mandatory, reputable firms often hold industry certifications that signal competence.

• Question: "Can you provide a copy of your current business license and any specialty certifications (e.g., Certified Landscape Professional, Irrigation Association Certified)?"
• Good answer: The contractor pulls out a recent license plate, shows the certification badge, and explains the renewal cycle. They also mention the licensing board’s website where you can verify the number.
• Red flag: Vague statements like "we’re fully licensed" without documentation, or a refusal to share the license number.

2. Confirm Insurance Coverage

Landscaping work carries risk—heavy equipment, chemicals, and open trenches can cause injuries or property damage. Proper insurance protects both you and the crew.

• Question: "Do you carry general liability and workers’ compensation? Can I see a certificate of insurance that lists me as an additional insured?"
• Good answer: The contractor emails a current COI, points out the coverage limits, and confirms that the policy names the homeowner as an additional insured for the project duration.
• Red flag: Saying they have "standard coverage" but refusing to provide the certificate, or offering to add you later after work has started.

3. Understand the Scope, Timeline, and Permits

Landscaping proposals can be vague. A solid scope breaks down each phase, the materials involved, and the expected start‑to‑finish dates. Permits are often required for grading, retaining walls, or extensive irrigation.

• Question: "Can you walk me through the detailed scope, including what’s included in the bid, the projected start date, and the estimated completion date?"
• Good answer: The contractor hands you a line‑item estimate (site prep, drainage, planting, hardscape), a Gantt‑style schedule, and a list of permits they will pull, noting which ones you need to approve.
• Question: "Which permits are required for this project, and who is responsible for obtaining them?"
• Good answer: They identify the specific city or county permits (e.g., grading, stormwater, electrical) and state they will file the applications, keep you posted on approval status, and include any permit fees in the estimate.
• Red flag: No timeline, or a promise that "permits aren’t needed" without checking local codes.

4. Clarify Payment Terms and Warranty

Landscaping contracts often involve multiple payments tied to milestones. A transparent schedule protects you from paying too much up front and gives the contractor incentive to finish on time.

Good Sign	Red Flag
Deposit limited to 10‑15% of total, with subsequent payments linked to completed phases (e.g., after grading, after irrigation install).	Demand for a large upfront deposit (30% or more) before any work begins.
Written warranty covering workmanship for at least one growing season, plus manufacturer warranties on plants and hardscape materials.	Oral warranty only, or a warranty that expires once you sign the final release.
Clear change‑order process that documents any scope additions and associated costs.	Vague “any extra work will be billed later” without a written amendment.

• Question: "What is your payment schedule, and what documentation will I receive at each milestone?"
• Good answer: They outline a schedule (e.g., 10% deposit, 30% after grading, 30% after hardscape, 30% upon final punch‑list), and say they will provide a signed invoice and a photo log before each invoice.
• Question: "Do you offer a warranty on workmanship, and how do you handle post‑completion issues?"
• Good answer: A written warranty of at least 12 months, a process for submitting a claim (photo evidence, written description), and a promise to correct defects at no extra charge.

5. Probe About Subcontractors and Materials

Many landscaping firms subcontract specialized tasks—excavation, irrigation, or lighting. Knowing who will be on site helps you assess quality and liability.

• Question: "Will any work be performed by subcontractors, and if so, are they licensed and insured?"
• Good answer: The contractor provides the subcontractor’s name, license number, and insurance COI, and confirms they are vetted and covered under the primary contract.
• Question: "What brands or sources do you use for plants, pavers, and irrigation components?"
• Good answer: They name reputable nurseries, specify paver manufacturers with warranty information, and explain why those choices suit the soil and climate.
• Red flag: “We use whatever is cheapest” or an inability to name specific suppliers.

6. Evaluate Communication and After‑Care

Even the best‑planned project can stumble if communication breaks down. You need a single point of contact and a clear process for post‑install maintenance.

• Question: "Who will be my primary point of contact during the project, and how often will I receive updates?"
• Good answer: The contractor assigns a project manager, promises a weekly status email or call, and provides a direct phone number.
• Question: "Do you offer a maintenance plan after installation, and what does it include?"
• Good answer: They outline optional seasonal services (e.g., pruning, irrigation check‑ups), pricing, and the ability to cancel without penalty.
• Red flag: No follow‑up plan, or a promise that “once it’s done, you’re on your own.”

Putting It All Together

When you sit down with a potential contractor, use the 15 questions as a checklist rather than a script. Take notes, ask for written responses, and compare at least three bids before deciding. The contractor who can answer each question confidently, provide documentation, and explain the reasoning behind their process is the one most likely to deliver a landscape you’ll enjoy for years without surprise costs.
