This is how a Chimney Sweep can take advantage of a homeowner!

Clean Your Own

This is a summary of a phone conversation I had with a very nice older woman in a North suburb of Chicago. I will refer to her as Mrs. G:

Mrs. G: Thank you for the information on the Chimney Balloon. I hired a chimney sweep to come to my home so I could have him measure to fit a Chimney Balloon.

Jason: That is a great idea. I know you expressed concern about getting your old damper open as it has rusted closed. How did that work out for you?

Mrs. G: It went well but the chimney sweep suggested an Exhausto Chimney Fan so I can seal up my chimney. He said it would cost about $900 to install one.

Jason: Exhaust makes a very good product Mrs. G. but I thought you said you do not use this fireplace at all?

Mrs. G: I never use this fireplace but the sweep told me this was a good way to stop heat loss through the chimney.

Jason: Well the Exhausto does have a feature that tops the chimney when it is not blowing, but if you really want to top your chimney it would be best to just have the sweep cap the chimney with a top cap plug.

Mrs. G: The sweep told me that the Exhausto will keep me from losing heat out the chimney and act as a top sealing damper.

Jason: Yes, but primarily the Exhaust is made to draw air up the chimney. It is perfect if you had a chimney that did not draft well and you use it often. In my opinion, You would be better served to get a more economical top sealing damper, like the ones made by Lymance,  if you are looking to seal the fireplace at the top and you would like to still have the option of using it. If you don’t plan to use the fireplace and you never have, and if you have no known smoke draft problem, you would be wasting money by installing an exhausted. Is this Chimney Sweep someone that you know and trust.

Mrs. G: Well, this chimney sweep is from the yellow pages, I have not used him before. But he says he knows what he is talking about. He thinks this will work to create the right amount of air in my chimney so it won’t be cold anymore.

Jason: Mrs. G. I think this guy is trying to up-sell you and does not have your best interest in mind. I would call another sweep and have him look at your fireplace. Ask him if he thinks a Chimney Balloon or a top sealing damper would work best for you.

Mrs. G: Well I already have signed the estimate for the Exhausto so they are installing it tomorrow since they had a cancellation.

Jason: Mrs. G I would encourage you to call to see if you can have this guy let you out of that estimate. I really encourage you to have another person look at this first. We can look up some reputable chimney sweeps through the National Chimney Sweeps Association and get you another opinion.

Mrs. G: Maybe that would be good I will call him and call you right back

Jason: OK, in the meantime I will look up some reputable sweeps in your area. I will have you a few phone #s by the time you call back.

Mrs. G: OK Jason, thanks, goodbye.

Mrs. G never called me (Jason) back. I can only assume this chimney sweep talked her into the installation again. I didn’t care if she bought a chimney balloon or not. I actually thought a lock top damper may be what she wants. But I knew for sure an exhaust was going to be overkill.

Do Chimney Sweep Logs work?

Q: Jason – I bought a Fireplace Chimney Creosote Sweep Log. You burn it like another log and it is supposed to release fumes to loosen creosote in the chimney. Do those things really work? – FW

A: It would be unfair to say that the chimney sweep type logs make no difference in your fireplace chimney. They, in fact, make such a small difference that it is almost imperceivable. But they do have a very effective marketing strategy. I don’t recommend them as maintenance items for fireplace chimneys. The chimneysweep type logs tend to give a homeowner a false sense of proper maintenance on sweeping their chimney. Nothing beats a good old brush scrubbing and inspection. – Jason

Very small flue with a smoke coming in the upstairs fireplace when we burn in the downstairs fireplace.

Smoke goes up the one chimney and back down the other.

Q: I have a house built in 1870, and the flue I would like to seal appears to be very narrow, somewhat jagged, and irregular in shape. The best I can tell, the opening appears to be about 6 inches deep, and 12 inches wide. Which size would be best for me? And do you think there is a wider opening further up the chimney? If so, would I be able to push the Chimney Balloon up there and then inflate it??

Also, like Maureen in the previous post, I have a smoke situation and am hoping your product will help. We have multiple fireplaces, and when I burn a fire in the living room downstairs, smoke enters my son’s bedroom upstairs. They are in the same chimney. This started happening after we added a chimney cap to keep birds and animals out. The guy who did the work came back and claims he sealed the flue heading into the boy’s bedroom. But we had one more fire at the end of last season and still smelled smoke in his room during the fire downstairs. Please advise… – JW

A: Dear JW, Well, to answer your first question… I would go with a 9×15 Chimney Balloon for that size hole to plug. It does not matter much if the hole is jagged and rough in shape as long as the hole is not any larger than 9″x15″ and has roughly parallel walls on at least 2 sides.

On your smoke crossover question…Yes, the Chimney Balloon will give you a very tight seal on your unused chimney so the smoke smell will not be sucked back into the home. I’m sure your Chimney sweep gave it a good try to seal it up, but there is no way to get as tight of a seal as a Chimney Balloon will offer. Even a fiberglass bat plug will allow odor back in through it. – Jason
