Some fireplaces have sharp edges

Q: Jason, Your customer service has been top notch, but I’m still not having good luck with the Chimney Balloon. I purchased one a year or two ago. Over time I noticed it had become deflated. I’ve not blown it back up a number of times in the past week. It must have a leak somewhere as it will not stay inflated. Do the valves develop leaks?

Anyway, I’m just a bit frustrated and wishing this worked better than it does. I’m not sure there’s anything to be done about it, but I needed to vent (no pun intended). – SR

A: Dear SR,
There are some applications that are just not hospitable to the Chimney Balloon. I’m afraid this may be one of those applications.

However, we have two products that are quite a bit more durable than the Chimney Balloon:

The Flueblocker  is a dense wool pad with a rigid air barrier sewn inside it.  Judging by your photos and the Chimney Balloon size you purchased before, my bet would be on the 13×35 Flueblocker. The length will be perfect, but you might have to trim a bit off the depth. I would try fitting it full sized first to see if it is a pressure fit, and then trim down from there if needed. Just like a haircut, you can always take more off, but you can’t glue it back on.

Another option is a Chimella. That would deploy up into your smoke chamber or flue tile. The Large Chimney Umbrella would cover either.

If you are having a hard time deciding on what one to go with, use our product selector tool to go step by step through your application.  Or just give us a call.
