That one weird trick for fixing a squeaky floor without ripping up carpet
So I had this spot in my hallway near the bathroom that squeaked every time you stepped on it. Drove me nuts for like 6 months. I tried a bunch of stuff: baby powder, screws from the crawlspace, even those expensive floor repair kits from Home Depot. Nothing worked. Then I remembered something from a forum post about using a syringe to inject wood glue directly into the seam. Picked up a 10-pack of syringes at Tractor Supply for about 8 bucks. Mixed up some Titebond III, stuck the needle right through the carpet backing into the subfloor gap, and pumped it in. Let it dry for 24 hours and it hasn't made a peep since. Has anyone else tried this or found a different trick for tricky spots?
