Glad you fixed your problem but that may be temporary. I don't know where you live but with the variation of temperatures of winter and summer you might be needing a thicker bead and not smoothing it out. You need the thickness so it can stretch enough without cracking. If you smooth it out you're thinning the bead therefore making it weaker. Did you dry the wood frame before applying the caulking? Hope it lasts a long time but if it doesn't I hope these tips will help do a longer lasting seal!
This just happened to us after hurricane milton. Our back patio doors had a water leak under the aluminum frame outside. That water seeped into our new hardwood floors water logging them ruining our living room 😑. Gonna this our and see if it works. After ripping up floors and testing it with the hose we found exactly where the water is coming in from. Thanks for these tips
