I'm based in Canada and I'm trying to find a suitable product to seal around the exterior vent of my gas fireplace. I've noticed that mice are getting in, so it's essential to seal the area around the vent cover. I need something that can withstand heat. Any recommendations?

If you're looking for something more rigid, consider using a high-temperature caulk. They’re often designed for this kind of application and can keep pests like mice out. Just be cautious with how you apply it to ensure there's no blockage of the vent.
You might want to check out heat-resistant silicone sealant. It works great for sealing around vents and holds up well against temperature changes. Just make sure to apply it properly and let it cure before using the fireplace.
