Sidewalk replacement The complete demolition, removal, and brand-new reconstruction of an entire sidewalk stretch or multiple continuous flags.
When a property's sidewalk has extensive cracking, scaling, or multiple DOT defects, a complete sidewalk replacement is more cost-effective than piecemeal repairs. The process involves full-scale excavation, re-grading of the subbase, setting new wooden forms, and pouring fresh concrete. All replacements in NYC must conform to DOT specifications, including the standard 1" in 5' slope pitch toward the curb.
