If you're planning a landscaping project in Westchester County, the first question is usually about cost. After three generations and thousands of projects across Bedford, Katonah, Pound Ridge, Armonk, and throughout northern Westchester, we've seen the full range. Here's what to expect in 2026.
Landscaping Cost Ranges in Westchester County
Westchester County landscaping costs run higher than national averages due to the region's rocky terrain, clay-heavy soils, steep slopes, and the permitting requirements in many municipalities. Labor costs in the New York metro area also contribute.
| Project Type | Typical Range | What's Included |
|---|---|---|
| Basic planting refresh | $2,000–$8,000 | Removing overgrown material, new shrubs, mulch, basic bed shaping |
| Patio or terrace | $15,000–$60,000 | Excavation, base preparation, natural stone or bluestone, drainage |
| Full property landscape | $25,000–$100,000+ | Design, grading, planting, hardscaping, irrigation, lighting |
| Estate-scale transformation | $75,000–$250,000+ | Multi-phase design-build with masonry, pools, outdoor kitchens, extensive planting |
| Retaining walls | $8,000–$35,000 | Natural fieldstone or manufactured block, drainage behind wall, permits |
| Driveway & entrance | $20,000–$80,000 | Belgian block, bluestone, cobblestone, or pavers with proper base |
These ranges reflect 2026 pricing for licensed, insured contractors using quality materials. Projects at the lower end of each range typically involve smaller areas, simpler designs, and standard materials. Higher-end projects involve custom stonework, mature plant specimens, and complex site conditions.
What Drives the Cost Variation?
Site Conditions
Westchester properties present challenges that flat suburban lots don't. Rocky soil requires jackhammering before you can plant a tree. Steep slopes need retaining walls, terracing, or regrading. Many Bedford and Pound Ridge properties sit on bedrock within inches of the surface — which affects every aspect of construction from drainage to footing depth.
Properties with mature trees add complexity. Working around established root zones, maintaining canopy clearance, and preserving specimen trees all require careful execution and sometimes arborist involvement. We've spent decades learning which trees can tolerate grade changes and which cannot.
Deer Pressure
Northern Westchester has among the highest deer populations in the state. A beautiful landscape that ignores deer will be eaten to stubs within a season. This affects plant selection (and cost) significantly:
- Deer-resistant planting typically costs 10–20% more upfront because the plant palette is more specialized
- Fencing for kitchen gardens or cutting gardens adds $3,000–$15,000 depending on size and material
- Long-term savings are substantial — replacing deer-damaged plants every year costs more than choosing correctly once
At Perennial Gardens, deer resistance isn't an afterthought. It's the starting point for every planting plan in our service area.
Materials
Material choices drive the largest cost differences:
- Natural Westchester fieldstone ($30–$60/sq ft installed) versus manufactured retaining wall block ($20–$35/sq ft installed)
- Bluestone from New York quarries ($25–$45/sq ft installed for patios) versus concrete pavers ($15–$30/sq ft installed)
- Specimen trees (caliper 4"+ or larger) can run $1,500–$8,000 per tree installed, versus nursery-standard 2" caliper trees at $400–$1,200
- Native plantings from regional growers versus big-box nursery stock — the regional material costs more but establishes better in local conditions
We source locally whenever possible. Local stone matches the geology your property sits on. Regional plant stock is hardened to the climate it will live in. This isn't sentimentality — it's practical knowledge built over eighty years of observing what lasts in this specific region.
Permits and Regulations
Many Westchester municipalities require permits for:
- Retaining walls over 4 feet
- Work within wetland buffers
- Driveway modifications
- Tree removal above certain caliper thresholds
- Stormwater management plans
In Bedford, Pound Ridge, and New Castle, the permitting process can add 4–8 weeks to project timelines and $2,000–$10,000 in engineering and application fees. An experienced local contractor handles this as part of the project. An out-of-area contractor may not know the requirements exist until they're already digging.
How to Budget a Landscaping Project in Westchester
Start with Priorities, Not Square Footage
The most expensive mistake we see is planning the project around area rather than impact. A well-designed 800-square-foot patio with proper drainage, quality stone, and considered planting will serve a family for decades. A 2,000-square-foot patio built cheaply will crack, settle, and need rebuilding within ten years.
Phase If Necessary
Many of our clients choose to phase work over two or three years. This allows for larger budgets per phase and better results. A common phasing approach:
- Year 1: Hardscaping — patios, walls, walkways, drainage (the foundation)
- Year 2: Planting — trees, shrubs, perennial beds, ground covers
- Year 3: Finishing — lighting, irrigation, final grading, garden structures
Phasing also lets the landscape settle and reveal issues (drainage patterns, sun exposure) that inform later phases.
Get Multiple Proposals — But Compare Correctly
When comparing landscape proposals in Westchester, make sure you're comparing:
- Materials: Natural stone vs. manufactured. Specify what you want and compare quotes on the same specification.
- Soil preparation: Will they amend your clay soil before planting, or just dig a hole?
- Warranty: What's covered and for how long? At Perennial Gardens, we guarantee plant material and stand behind our construction.
- Insurance and licensing: Verify current liability insurance and a Home Improvement Contractor license (required in New York State for projects over $500).
- Subcontracting: Will the company bidding the work actually perform the work? Some firms subcontract everything.
Why Local Expertise Matters
Westchester is not a generic market. The soil, the slopes, the deer, the regulations, the weather patterns, and the aesthetic expectations of homeowners here are specific. A contractor from out of the area may offer a lower bid, but they won't know that the Bedford clay freezes and heaves pavers that weren't set on a proper base, or that the hemlock woolly adelgid has made Canadian hemlock a poor choice for screening in this region.
We've been landscaping properties within forty miles of our Bedford garden center since 1946. Three generations of project experience on the same terrain. That accumulated judgment — about what stone weathers correctly, which trees tolerate our winters, how deep to set footings in our frost line — doesn't appear on a proposal. But it shows up in how the work holds up ten years later.
