To estimate the cost of a walkway as of 2015, calculate the total square footage of the path by multiplying the length times the width, and then multiply that figure by $4 to $6 per square foot for a plain concrete walkway. To add one color or a simple finish, use a figure of $6 to $10 per square foot, and for multiple colors or a patterned walkway, use a figure of $8 to $12 per square foot.
Custom walkways with hand-applied details such as stenciling, stained accents, borders, saw-cut designs or unique details requiring special forms may be $12 to $15 per square foot or more. If a contractor needs to form the walkway into intricate shapes or if the ground requires extensive prep work, the cost increases. If workmen need to break up and remove existing concrete, figure an additional $2 to $6 per square foot.
The biggest factor in determining the cost of a walkway is the type of material used. For custom work, a homeowner may want to get two or three estimates from different contractors in order to determine a price for the complete job.
Typically, a contractor should only need one day to pour an average-sized concrete walkway.
