For construction professionals in Portland, Maine, the cost of building a retaining wall can vary significantly based on materials and labor. As of 2025, expect to pay approximately $28–$33 per square foot for block and cap units, with labor costs ranging from $35–$45 per square foot. Additional costs include base gravel and drainage stone, which typically account for 15% of the total material cost, and geogrid reinforcement, which can add 5%–8% to the total.
Retaining walls in Portland must withstand freeze-thaw cycles, heavy rains, and coastal winds. A block system engineered for strength and styled for New England curb appeal is essential. Professionals can leverage AI-driven estimating to ensure the right block, footing, and price without guesswork.

Material selection is crucial for long-lasting performance. Portland's climate demands blocks with high compressive strength, integrated drainage cores, and textured faces that blend with local architecture. Engineers can recommend heights, geogrid spacing, and setback angles that meet local codes.
Concrete segmental blocks are popular for their engineering and ease of installation. For a heritage look, granite or fieldstone veneer is an option. Our estimating engine can price both instantly, allowing professionals to balance aesthetics and budget.
