How much does a stone retaining wall cost in Hillsborough, NJ?

A stone retaining wall is an investment in function and curb appeal. Costs depend on height, materials, drainage, and whether the wall is structural or decorative. This guide gives local price ranges and helps you plan a Hillsborough project.

Typical costs and price per foot

Costs are usually quoted per linear foot and vary with height and construction method. Typical local ranges:

• Small garden wall, 1 to 2 feet high, dry laid: $40 to $120 per linear foot
• Mortared natural stone wall, 2 to 4 feet high: $120 to $300 per linear foot
• Structural retaining wall with geogrid, taller than 4 feet: $200 to $400+ per linear foot
• Concrete block or reinforced wall with stone veneer: $80 to $220 per linear foot

These are ballpark figures for Hillsborough and surrounding Somerset County neighborhoods. Site conditions can change costs significantly.

Site and design factors that drive price

Key factors to consider when estimating cost:

• Height and length: taller, longer walls need stronger foundations and drainage
• Soil type and slope: unstable or wet soils require additional engineering
• Drainage and backfill: weep systems, perforated pipe, and proper backfill are essential
• Materials: natural stone, cut stone, boulders, and veneer vary in price and labor
• Reinforcement: geogrid and footings increase stability and cost for higher walls
• Access: tight sites or haul distances for heavy stone increase labor time

Proper drainage and correct base preparation prevent failure and often cost less than fixes later.

Construction options and timeline

Common approaches with typical timelines:

• Dry stacked stone, small garden wall: 1 to 3 days
• Mortared natural stone, medium wall: 3 days to 2 weeks
• Engineered retaining wall with geogrid: 1 to 3 weeks, depending on size and inspections

Permits are often required for walls over a certain height, check Hillsborough township rules before starting.
