repair of a fireplace hearth
The hearth in my 60 year old house has sunken below the wood floor by about a half an inch. The hearth is granite, measuring 51 by 16", about one inch thick. I have removed the mortar along the sides but can only maneuver the slab by a quarter of an inch. I cannot, therefore, get under it to lift it up in order to replace cement board or new mortar. The furnace is directly below the fireplace so I cannot get access underneath the slab. Any suggestion on how to lift the granite without tearing out the floor boards?
