"Large or Complex Projects - extensive curb modifications or custom installations can cost $1,200-$3,000 or more. These projects often involve additional planning, permits, or structural considerations, which can increase overall costs. Many jobs are completed within the lower part of this range.

Full Replacement - complete curb or sidewalk replacements typically start around $3,000 and can exceed $5,000 for larger, more involved projects. These are less common and usually reserved for significant repairs or upgrades, with most projects falling into the lower to mid portions of this range."
