The three top walkway repair methods are: #1 Remove & Replace, #2 Slicing, and #3 Grinding.
Remove & Replace method: If you had a budget of $2,000, you might be able to remove and replace 1 trip hazard and you would need to apply for and pay for a permit from the city to begin work. Work done using this method is also eligible for ADA tax credit & deductions to mitigate up to $20k of the cost as well.
Concrete slicing method:The same budget if used with concrete slicing might allow you to repair 25-35 hazards and no permit would need to be purchased from the city. Hazards that were over 3” in height or shattered pavement would still need to be removed and replaced. Work done using this method is also eligible for ADA tax credit & deductions to mitigate up to $20k of the cost as well.

Grinding method:Finally the same budget with grinding might repair 35-45 hazards and no permit would be needed, however any repairs over 1” in height could not be repaired using grinding and would have to be removed and replaced. Also if the hazards were next to walls, poles, or curbs then the grinder would most likely not be able to remove 100% of the hazard but would leave 1-3 inches of the hazard intact next to these obstacles.
