How do we deal with concrete that is flush to hardwood floor?
we recently bought a house that has an addition that was previously a garage. The previous owners leveled the garage to the rest of the house and added on 4 feet to the original house. When they did this they made the addition flush with the original hardwood floor and then carpeted the whole house. We would like to rip up the carpet and refinish the hardwood, but with the concrete being flush to the original floors we are just at a loss on how to proceed. Any advise would be great! Everything I google just talks about laying hardwood over the concrete.
