Is there anything really difficult about installing crown molding? The builder of my house wants to charge $450/room. I went to Home Depot and saw 8 foot strips for like $3. I would only need like 6 strips per room. I'm not that much of a handy man, but I think all I would need is an air nail gun and a saw that will cut the corners right so it connects well. Anyone ever do this? and did you think it was that difficult?
