Tip for those living in cold climates

I had my house door freeze shut for the first time.

Good plan. Isn't it embarrassing when you can't get in or out?
I drive a '97 Suburban. The old doll needs her door seals wiped with antifreeze,
a couple times each winter, when we get a warm spell.
So far this year, the shade temp has swung from +47C to -33C, maybe -35C.
Not 200 cm snow in the valley yet but give it 2-3 more weeks, it's coming.

Should do the seals on the sides and top too, not just the sweep.

-35C brr the Maritimes usually don't get that cold.

Surprisingly I have experienced this problem here in Australia. Not on any house doors but on the doors to our walk in lab freezers at work (used to store polar ice cores) which were held at -18C 24/7. After wrestling with stuck doors for some months we replaced the doors seals with those that had embedded electrical heater tape. The tapes used something like 10W so were kept switched on most of the time. A few years after installation one of the tapes in one of the seals got slightly crushed and developed a hot spot which started smouldering the door seals. This triggered the particle counters in the lab before the smoke detector fire alarms sent for the fire brigade.
