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.

From my slab-on-grade project, I chose a full glue-down with a moisture barrier and polyurethane adhesive. It feels premium in our open living area, no hollow spots, and transitions to tile were clean with proper trim. Floating sounded appealing for speed, but I worried about long-term squeaks and the feel in a large space—glue-down again, for me.
