It is difficult to give an accurate estimate without knowing the specifics of the job, such as the size of the area and the type of grout involved. However, on average, professionals typically charge around $10-15 per square foot to remove and replace grout. Keep in mind that this is a general estimate and may vary depending on your location. Additionally, it's important to factor in other costs such as supplies (grout, adhesive, sealant) and labor. If you're doing the work yourself, be sure to account for your time as well.

It can cost anywhere from $0.50 to $10 per square foot to remove and replace grout, depending on the type of grout, the size of the project, and the contractor you hire. For example, epoxy grout can be more expensive than traditional grout, and a small bathroom may cost less to re-grout than a large kitchen. Generally speaking, you can expect to pay about $5 per square foot for professional labor costs to remove and replace grout.
