An electrician has excavated a wall recess for a new light switch, but the opening is now too deep and some of the surrounding plaster has chipped away. Looking for an experienced handyman or plasterer to: * Rebuild the back of the recess with suitable masonry repair mortar. * Securely fix the metal back box, ensuring it’s correctly positioned and flush with the finished wall. * Repair the surrounding plaster, leaving a smooth finish ready for painting. I already have the back box. The electrical wires have been temporarily capped, and the electrician will return to connect the switch. Photo attached. Looking for someone experienced with masonry repairs and neat finishing work.
