Recently we put an addition onto the house. I used planed home-sawn white pine lumber, that had been air dried for about 10 yrs.for the sub-floor. The sub-floor was
glued and nailed diagnally. We had 1/4" birch under-lay installed by a professional,insure warranty. About a month later the staples started to work their way up through
the vinyl. They are now starting to lift the Dura-plank also. Any ideas?
