Landscaping Cost Calculator — 2026 Estimate

A quarter-acre yard is approximately 10,890 sq ft. At $1–$3/sq ft installed, total sod cost runs $10,900–$32,700. Bermuda or fescue sod at the low end of prep requirements lands around $12,000–$18,000 installed. Adding existing lawn removal ($0.50–$1.50/sq ft) adds $5,450–$16,335 to that. Most contractors price large jobs more competitively per sq ft than small jobs, so actual bids may come in at the lower end of these ranges at scale.

Seeding costs $0.10–$0.30/sq ft for materials versus $1–$3/sq ft for sod installed — roughly 5–10x cheaper upfront. But seeding requires 2–3 growing seasons to establish, weekly watering, and weed control. Sod gives immediate results (walk on it in 2–3 weeks), works any time of year, and controls erosion immediately. For small areas, high-visibility areas, slopes, or high-traffic yards: sod is worth the premium. For large acreage on a budget with patience: seeding makes sense.

A 400 sq ft paver patio (roughly 20×20 ft) costs $6,000–$16,000 installed using concrete pavers. Natural stone runs higher: $10,000–$32,000. Breakdown: excavation and base prep $1,500–$3,500, geotextile fabric $200–$400, gravel base $800–$1,500, sand setting bed $300–$600, pavers (materials) $1,200–$4,000, labor $2,000–$6,000. Curved edges, multiple levels, steps, and integrated lighting add to cost. Get at least 3 bids — patio prices vary 30–50% by contractor in the same market.

Most jurisdictions require a building permit for retaining walls over 3–4 feet in height. Walls over 4 ft typically require an engineer's stamped drawings showing structural calculations and drainage design. Permit fees run $200–$1,000. Unpermitted walls that fail can create significant liability — especially if they retain soil near a property line or structure. Always check with your local building department. Low garden walls under 30 inches typically need no permit in most areas.

French drain installation costs $25–$80 per linear foot, or $1,500–$6,000 for a typical 60-foot residential run. The main variables: trench depth (shallow 12” vs. deep 36”+), soil type (clay costs more to excavate), pipe diameter (4” vs. 6”), outlet options (daylight vs. dry well), and whether landscaping needs to be replaced after. In clay soil with a deep trench, costs can reach $80–$100/linear foot. Dry wells (percolation pit for the outlet) add $1,000–$3,000. DIY French drain material cost: $5–$15/linear foot.

A large shade tree (2–3 inch caliper, balled and burlapped) costs $500–$3,000 installed, with specimen trees (4–6 inch caliper) running $3,000–$15,000+. The tree itself is often 40–60% of the total; installation labor, staking, and backfill amendment make up the rest. Oak, maple, and linden in 2.5” caliper B&B typically run $800–$1,500 for the tree plus $200–$500 to plant. Small ornamental trees (dogwood, redbud, Japanese maple) in 1.5–2” caliper run $150–$500 installed.

Key signs: (1) water pools within 6 ft of your foundation after rain, (2) basement or crawl space moisture despite no plumbing leaks, (3) standing water in yard more than 48 hours post-rain, (4) visible soil erosion or ruts, (5) foundation cracks consistent with water pressure, (6) sump pump runs constantly. A simple test: use a 10-foot level and measure slope from foundation. Proper grade is 6 inches of drop in the first 10 feet away from the house. Less than 2 inches of drop over 10 feet means you likely have a drainage problem.

Studies show landscaping returns 100–200% of cost at resale when done well. Highest-ROI investments: (1) Sod and lawn — first impression, 100–150% ROI; (2) Mature trees — add 3–15% to home value per USDA study; (3) Paver patio or deck — extends usable living space, 60–80% cost recovery; (4) Proper drainage — prevents damage, no ROI calculation needed but critical; (5) Foundation plantings — shrubs and mulch beds frame the home, highest visual impact per dollar. Avoid overbuilding for the neighborhood — the $80,000 hardscape in a $250,000 neighborhood won’t recoup.
