we are renovating and adding on to a Houston mid-century. the house has a step down den with real terrazzo flooring that we want to preserve. we have two problems - how best to restore that terrazzo, and how to remove terrazzo where we don't want it (and how much we should expect to pay for demolition and prep). with regard to restoration, the house is in great shape, the foundation has held up well, but there are a couple of prominent cracks that show up in the flooring. carpet had been laid over the den and the wood strips, old glue, and a few nail or screw holes have to be filled. regarding replacement, we have rooms that adjoin the den where tile was placed over the terrazzo. we want to remove the tile and use wood flooring, and so the floor level (original terrazzo) needs to be lowered sufficiently to provide a smooth transition to the original terrazzo that we are preserving. ideas and comments would be great!
