Hiring a Koi Pond Contractor: 18 Critical Due Diligence Steps

Industry Red Flags

• Many liner installers: unlicensed, shoestring budgets, commingling funds (illegal)
• Low entry barrier: shovel, rake, hose, wheelbarrow = "contractor"
• 18" liner ponds often permit-exempt = no oversight

Finding Qualified Pros

• American Society of Landscape Architects (ASLA)
• Association of Professional Landscape Designers (APLD)
• Interview 3+ for cost/approach comparison
• Never choose on price alone — value + references + experience

Reference Verification (The Gold Standard)

1. Request LAST 4-5 consecutive clients (not cherry-picked best)
2. Contact all — ask to visit projects
3. Inspect WITHOUT contractor present
4. Key questions:
   • Finished on time?
   • Budget honored?
   • Problems resolved smoothly?
   • Property/privacy respected?
   • Change orders fair?

Legal/Financial Due Diligence

• State Contractor's Board — license current? surety bond? (protects deposits)
• Insurance — $1M+ liability (neighbor damage), current workers' comp (you're liable for uninsured workers)
• Legal status — verify no illegal workers (you're ultimately responsible)
• Better Business Bureau — complaint history
• Police department — fraud/drug records (some disappear with funds, reappear later)

Payment Protection

• Never pay ahead of materials/labor on site
• Every check = lien release for that amount
• Final lien release at completion (prevents supplier liens on YOUR property)

Contract Essentials

• Detailed scope of work
• Material specifications
• Realistic timeline with milestones
• Payment schedule tied to milestones
• Change order process
• Warranty terms
• Dispute resolution

This process protects both parties. The contractor who resists scrutiny isn't the one you want.
