Dear James: We have a concrete driveway and a walkway, and both are crumbling. We have received replacement quotes from contractors. What details are most important to choose one? —Mike S.
Dear Mike: A crumbling concrete sidewalk and driveway can be hazardous to walk on in addition to looking really bad. It doesn’t take much roughness and unevenness to cause someone to fall. Once the concrete starts to crumble, it will continue to get worse, especially in climates with daily winter freeze-thaw cycles.
