We have been remodeling a house for the past 2 1/2 months. We had 4'' white oak hardwoods installed in about 1900 sqft of the house. The wood sat in the house for 12 days, bundles in every room, to acclimate. Shortly after they were installed, sanded, stained and one coat of poly applied, they cupped. We live in the Southeast with high humidity and the house has a crawl space.
The house has ventilation vents, poly covering most of the crawl and no signs of standing water. We have opened all vents, installed 3 ventilation fans and the moisture content hasn't really gone down. One guy came out and wanted to remove all of the crawl space insulation and put in new poly for $2800...seemed a little steep.
The installer thinks the floors will "lay" down one the crawl is dry. I'm not convinced and we are eager to get into the house. I've read a lot about not sanding cupped floors but it is very tempting to sand the floors and move in. The moisture reading on the subfloor is 12 to 14%. The moisture reading in the insulation is 22 to 30%. The moisture reading on the hardwood is 5 to 7%.
Looking for some sound advice.
