How to Patch a Hole in Subfloor

This is not gonna work- A floor register got installed right by the front door. Let’s see if we can move it… The boots for these registers are held in with roofing nails. So, I use a cat’s paw and a hammer to pry on the boot and then I pop the nails out. Luckily, the flex line wasn’t hooked up yet. I asked The New Guy if he could work late and patch this hole, he mumbled something about dinner plans and drove off. I guess I’ll do it myself. I start by cutting a piece of subfloor 2 inches bigger than the hole all the way around. Then I install a 3” screw in the middle to use as a handle. Next, I put subfloor adhesive around the edges. I lower it the piece down through the floor using the screw as a handle and pull it back up tight. I use the claw end of my hammer to hold the board tight while I fasten it in place with screws. If you ask me, glue is like horsepower- you can’t have too much. I found the piece of subfloor that was cut out for the floor register and put it right back in the hole. I’m screwing it down with 1 ½” T25 deck screws. Honestly, I would argue that this repair is stronger than the original floor- what do you think? @hausplans #build #howto #construction #diy #contractor #hack
