We purchased fireplace doors from Alternative Heat. They walked through our options with us, explained the various pros and cons while giving us time to make a decision. The turn around time was super fast, and we ended up having the doors installed within a few weeks, just in time for a big blizzard. The install was quick an professional and they ended up identifying some safety issues with our chimney(not a chimney scam — they told us to contact whatever reputable mason we usually deal with, which we did, and he confirmed what they told us). I’d recommend them to anyone. Plus the doors are so much nicer looking than the options available from a big box store.
