The cost of bricking up a window generally ranges from $300 to $800, though it can vary based on factors like the size of the window, brick type, and labor. Smaller windows or those in easy-to-access areas tend to be on the lower end of the scale. However, matching bricks to the existing structure and adding insulation or finishing touches may increase costs. Projects with complex brick matching or unique architectural features might also see higher prices due to additional labor and materials required.
