Sometimes you just gotta pick function over form in winter.
Honestly, that’s the truth. I’ve seen folks spend way too much time fussing with aesthetics when it’s freezing out—just get it sealed and worry about looks in spring. For a split frame, I’d grab some painter’s caulk (the flexible kind), press it into the crack, then cover with plastic sheeting and tape. Not pretty, but it’ll keep the wind out till you can do a real fix. Foam board works too, but I’ve had better luck with heavy-duty shrink plastic kits for sash windows. They’re ugly, but man, they work.
Had a job a few winters back where the homeowner tried to patch a split with wood filler in January—didn’t end well. That stuff never sets right in the cold, just crumbled out by February. Ended up using clear caulk and a heavy-duty contractor bag, taped tight. Not pretty, but it held up until April when we could get in there for a proper repair. Honestly, when it’s below freezing, I’ll take ugly but warm any day.
Yeah, wood filler in the dead of winter is basically asking for trouble. If it’s below freezing, it’s just not going to cure right—seen it turn into brittle dust more times than I can count. I’ve done the same thing with caulk and a plastic sheet before, though I’ll admit my “temporary fix” looked like I was prepping for a hurricane rather than a split window frame. At least it kept the wind out.
One trick I’ve used is painter’s tape and some foam backer rod jammed in the split before caulking—gives the caulk something to grip and adds a bit of insulation. Not pretty, but at that point, aesthetics are out the window (pun intended). Once spring rolls around, then you can get in there with epoxy or splice in some new wood.
Honestly, I’d rather deal with an ugly patch than frozen pipes or a sky-high heating bill. Cold weather repairs are always about survival mode first, looks second...

Couldn’t agree more. Had a customer last January who tried to use wood filler at 20°F—came back two days later and it was just dust in the crack. I’ve stuffed old socks and duct tape in splits before when things got desperate. Not pretty, but you gotta keep that cold out somehow. Springtime’s for making things look nice again.
