I had water get under my hardwood floor and it caused the sub-flooring to swell, making the hardwood cup up and look un-even in one area. Is it difficult to take up the existing hardwood without damaging it? And then re-installing it back again following repairs?
Dear Steve Check the moisture content of the floor and subfloor and don't re-install it until the MC (moisture content) is between 6-8% or the standard indoor MC for interior wood in your area. Cabinet makers will know this.
