Labor vs. Materials Breakdown

Project Type Labor % Materials %
Planting/softscape 50% 50%
Lawn installation 45% 55%
Paver patio 60% 40%
Retaining wall 55% 45%
Irrigation install 50% 50%
Maintenance 90% 10%

Factors That Increase Costs

Expect to Pay More When:

  1. Site access - Slopes, stairs, or narrow gates requiring hand-carrying materials
  2. Soil conditions - Rocky soil, heavy clay, or need for drainage solutions
  3. Demolition/removal - Removing existing hardscape, stumps, or large plantings
  4. Drainage issues - French drains, regrading, or retaining walls
  5. Permit requirements - Large walls, decks, or structures need permits
  6. Peak season - Spring (March-May) is busiest; expect higher prices or longer waits
  7. Premium materials - Natural stone, exotic plants, or custom features
  8. Design complexity - Curves, multiple levels, or intricate patterns

Seattle-Specific Factors:

  • Premium labor market
  • Space constraints and access in urban lots
  • Green stormwater requirements (rain gardens, permeable paving)
  • Native plant requirements in some areas

Eastern WA Factors:

  • Xeriscaping design for water efficiency
  • More extensive irrigation systems
  • Wind and temperature extremes affect plant selection

Money-Saving Tips

  1. Phase your project - Install hardscape year one, planting year two
  2. Buy smaller plants - 1-gallon plants cost 1/3 of 5-gallon but catch up in 2-3 years
  3. Use native plants - Lower maintenance, no irrigation once established, often cheaper
  4. DIY what you can - Mulching, simple planting, and maintenance are homeowner-friendly
  5. Off-season scheduling - Fall (October-November) offers better pricing and planting conditions
  6. Get multiple quotes - Landscaping varies 40%+ between contractors
  7. Start with a plan - A $500 design can save thousands by avoiding costly mistakes
  8. Consider synthetic turf - High upfront cost but zero maintenance in the right applications
  9. Group purchases - Order mulch, soil, or plants with neighbors for delivery savings

Red Flags: Too Cheap or Too Expensive

Warning Signs (Too Cheap):

  • Quote 40%+ below competitors
  • No contractor license (check lni.wa.gov)
  • No written contract or plant specifications
  • Cash-only payment required
  • No warranty on plantings
  • Vague material descriptions ("we'll figure it out")

Warning Signs (Too Expensive):

  • Quote 50%+ above competitors
  • Pushing premium materials without explaining alternatives
  • Large deposit required upfront (over 30%)
  • No itemized breakdown
  • Won't explain pricing differences from competitors

Healthy Range:

Three comparable quotes should fall within 25-30% of each other.


How to Compare Bids

Every landscaping quote should include:

  1. Detailed scope - Exact plants (species, size), materials (brand, color), quantities
  2. Site preparation - What's included (grading, irrigation, soil amendment)
  3. Itemized costs - Plants, materials, labor, delivery, equipment
  4. Timeline - Start date, completion date, weather contingency
  5. Warranty - Plant replacement guarantee (typically 1 year)
  6. Maintenance - Establishment watering, follow-up visits
  7. License and insurance - WA contractor license verification

Questions to Ask:

  • "What size plants are included?"
  • "What's your plant warranty?"
  • "Who does the watering during establishment?"
  • "Are permits included if needed?"
  • "What happens if plants die within the warranty period?"
  • "Is site cleanup and debris removal included?"
  • "Will you provide a maintenance guide for the new landscape?"

Best Planting Times in Washington

Region Best Planting Season Notes
Western WA October-November, March-April Fall is ideal; mild winters allow root establishment
Eastern WA March-May, September-October Avoid extreme summer and winter
Mountains May-June, September Short growing season

Why Fall is Often Best: Plants establish roots through winter rains without heat stress. They're ready to grow come spring. Labor costs may be lower due to reduced demand.
