After our experience with the folks at Hearth and Patio (Monroe Road), we went looking for another option for our fireplace doors. The only other option we really had was the Firehouse. We did entertain the notion of going to the other Hearth and Patio near Northlake, which is why we took the trek all the way up into this part of town, but we stopped here first.
To start with, the store is a lot bigger. By that, I mean it's huge. However, the fireplace doors are a much smaller part of the store. They have a small little kiosk to see the selection and get an idea of what they look like. From that, you have to decide what you want and make selections and whatnot. So as far as that goes, it's not quite as good as Hearth and Patio.
However, the staff is so much better than Hearth and Patio, it's not even close - they are helpful, and give you advice, and help you figure out what you really want, rather than just trying to sell you something. Big thumbs up there.
Plus, when you're done - or while you're thinking - you can wander around and look at all the cool stuff for the patio, for when it warms up. Lots of other ways to spend your money.
