Brick Walkway Costs and Considerations. A professional will charge something on the order of $8 to $15 per square foot (or more) to install a brick walkway. For a basic 25-foot long by 4-foot wide walkway, thatâs an estimated cost of $800-$1,500. The labor required to install a brick walkway is a major cost determinant. For example, a relatively straight walkway that has a simple pattern will cost less than a twisting, turning walkway that requires numerous cuts.
