I’m in the middle of a major home renovation and have hit a snag with my flooring. I’ve settled on a beautiful wide-plank engineered hardwood for the main living area, but I’m completely torn on the installation method. The subfloor is concrete slab on grade, so I know a proper moisture barrier is non-negotiable. My contractor is pushing for a full glue-down installation, arguing it’s the most stable and will eliminate any potential hollow sounds or movement. However, I’ve been researching a floating floor installation using a premium underlayment with a built-in vapor retarder. The appeal there is a faster, less messy install and the potential for easier replacement down the line if a plank gets damaged. My main worry with floating is whether it will feel as solid and premium underfoot as a glued floor, especially in a large, open-concept space. I’m also concerned about expansion gaps and how to handle the transition to the tiled kitchen properly with each method. The cost difference is a factor, but honestly, I’m more focused on long-term performance and avoiding any callbacks for squeaks or gaps. Has anyone been through this specific decision with engineered hardwood on slab and lived with the result for a few years? I’d love to hear what you chose and if you’d do it again.
