I have a house built in 1940 which still has the original clapboard under the cedar siding. When the cedar was installed there was no barrier installed. Therefore, it is directly on top of the clapboard. Some sections have come down and we would now like to remove all of the cedar to get the house back to its original appearance. Is it possible to remove the cedar and salvage the clapboard or will we have to replace the clapboard? What would we have to do to the clapboard if it is salvagable? We have a 7 inch exposure on the clapboard with a very thick board which has a very distinctive look as opposed to most "sidings" available today. I have been told by carpenters that the wood would have to be custom made, that a traditional siding is not as thick as what we have. Any help would be appreciated.
