When it comes to solid hardwood, the nail-down method is the installation approach that professionals rely on — and for good reason. Each plank is mechanically fastened to the subfloor using nails or staples, creating a connection that holds firm as the wood naturally expands and contracts with changes in humidity. That movement is normal. What isn’t normal is a floor that wasn’t installed to handle it. In Seminole County and Orange County, FL — where summer humidity regularly climbs before dropping significantly in the cooler months — that mechanical connection matters. A floor that’s simply glued or floated doesn’t respond to wood movement the same way. Over time, the difference shows up as squeaks, gaps, or planks that lift at the edges. We use state-of-the-art equipment and follow NWFA installation guidelines on every nail-down job. That means subfloor inspection, moisture testing of both the wood and the subfloor, and proper acclimation before a single nail goes in. It’s not a shortcut process — but it’s the one that produces floors that hold up for decades.
