About four years ago, we had some wal-to-wall carpeting installed in one
of our bedrooms. Lately there has developed a bulge in the carpet at
about the middle of the room. The bulge goes right down the middle from
one side of the room to the other. I assume that it is probably the
underlay that is the problem. Any suggestions as to the fix? Do I have
to remove the bed, dressers, armoire, etc and call in a specialist?
