Can new sub-floors or generally wet job sites damage a new wood floor?
Wet subfloors can be caused by the rain or snow when the roof is open during construction, water spilled from tub saws or drywall wet work being done on the subfloor before the installation of flooring, (to name a few sources). After installation of the hardwood flooring mud and water or snow may have been tracked into the site during construction. Also plywood and OSB board may have been installed with a high MC. “Crowning” is often the result of wet site conditions, which may not be detectable when the flooring is sanded but will later show up after the home is properly heated. Cracks from compression set frequently occur on jobsites where excessive moisture is a problem.
