Squeaky laminate floor on top of leveled wood subfloor
Can I fix a squeaky laminate floor on leveling compound from underneath? My wood subfloor was leveled (badly by a contractor!). I've got nasty squeaks from my laminate floating floor all over the place. I have access to most of the area from my basement. Can I cut away from below and shim? My question is will I have to cut or chip through the hard leveling compound to get to the laminate? Or is there a a spray foam or some kind of product I can drill holes and inject it in to fill the air spaces that are causing the bounce and squeaking!!???? It has been driving me nuts for 2 years - contractor and retailer took a walk on this, I have no recourse but to sue, which I have neither the time or cash to do so.
