Why a square-foot price can be misleading
Two damaged areas of the same size can require very different work. One may need shallow preparation and a localized repair; another may involve deep removal, exposed steel, forms, restricted access, water conditions, or several mobilizations.
A useful price follows a defined scope: removal limits, preparation, repair method, finish, curing, access, protection, cleanup, and handling of hidden conditions.
The main cost drivers
Depth and extent of unsound concrete, reinforcement, forming, demolition and disposal, material requirements, finish matching, drainage, coatings, occupied-property access, and traffic restrictions all affect labor and sequence.
Small work can also carry setup, protection, sourcing, travel, and cure-control needs that are not proportional to the visible square footage.
When photos are enough to start
A wide photo, close-ups, scale, address, access notes, and views of water or adjacent finishes can establish whether a request fits the service. They cannot always show depth, movement, hidden corrosion, base condition, or total unsound area.
Multiple locations, uncertain scope, HOA or manager documentation, exposed steel, railing posts, or drainage usually justify field review before a written construction price.
The $250 evaluation and credit
The $250 Site Evaluation + Written Bid Package pays for field evaluation and proposal preparation when a responsible scope cannot be built from photos. The $250 is credited back if the construction project is approved within 30 days.
The evaluation does not guarantee that every area can be repaired. The written proposal identifies the approved scope, exclusions, and conditions that may require a written change order.
