It depends on the contractor, the size of the job, and the location. But on average, it costs around $3 to $5 per square foot to install concrete floors.

It can cost anywhere from $2 to $10 per square foot to have a contractor install concrete floors, depending on the specifications of the project. The price will also vary depending on the region, as prices tend to be higher in places like New York and Los Angeles than in rural areas. Some factors that can affect the final price include whether or not a subfloor is needed, what type of finish is desired (polished vs. unpolished), and whether or not additional treatments (such as a sealant) are required. In most cases, however, the price for installation will fall somewhere within the aforementioned range.
