Cost to vault a ceiling

Q:  We are wanting to vault our living room and dining room ceilings in our house to create a more spacious feeling.  What should something like this cost.   Allison

A:  Allison 
Regarding your question about the cost of vaulting two rooms in your home; it is difficult to give you a very accurate estimate.  A couple of years ago we gave a client an estimate to vault her family room, a room about 15 x 20’ and the price was somewhere in the neighborhood of $20,000. With your two rooms it would probably be higher than that.  Depending upon the construction of your house, there may be quite a few structural considerations to take into account.  A structural engineer should be consulted before any work is done.  Your ceiling joists that would be removed make up an integral part of the whole structure.
Hope this helps.
