## Questions & Answers

**Q: How do I determine the correct size for my fireplace flue?**
A: Measure your flue's interior and choose a Flueblocker the same size or slightly larger. The wool pad pressure-fits and can be trimmed with scissors. Use the sizing guide to match your flue shape—round, square, or rectangular.

**Q: How difficult is installation? Do I need any special tools or supports?**
A: Choose an install spot you can reach by hand. Measure with a tape or ruler. A narrow area above the firebox is ideal. For higher spots, use 6” handle extenders to place the wool pad securely.

**Q: Will the product completely block cold drafts, odors, and heat loss?**
A: When fitted correctly, the FlueBlocker stops heating/cooling loss, drafts and odors from a dormant chimney. To eliminate odor, make sure you vacuum out all the ash from the firebox and seal any ash chute or outside intake attached to the firebox.

**Q: Which is right for my situation – a FlueBlocker or a Chimney Balloon?**
A: The Flueblocker is a durable, reusable chimney plug that handles moisture and is ideal for long-term use. The Chimney Balloon offers a tight seal and a breakaway feature for safety if a fire is lit accidentally.

**Q: How durable is the material? Is it worth the price?**
A: Chimney is harsh, moist, acidic environments. The Flueblocker uses coarse ionized Herdwick wool and durable resin hardware to seal air, wick moisture and resist odors. Chimney Balloons use a heat-reactive laminate to withstand chimney air conditions.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Sometimes you just have to pay for quality
*by K***R on January 16, 2023*

Let's just deal with the elephant in the room first - this thing seems stupid expensive for what it is. I mean, 50 bucks for a circle of fabric with a cheap plastic handle, wth?But I will say this: it works, bigtime, and for a tiny fraction of the cost of getting a chimney repairman to try to replace a leaky damper.The fabric circle is really a super-heavy-duty, all natural, woven sort of felt from, they claim, special sheep with really dense wool. I can't speak to that but I'll admit that I've never seen anything quite like it.Despite its thickness and solidity, though, it was not terribly difficult to trim up with heavy shears. Note: DO NOT attempt to make an exact fit! You want it to be a little big, so it'll squish into the flue and stay there from friction.I also had to cut a perpendicular slit to allow the damper control rod to pass through. This, too, was no big deal.And the result? Not only did all chimney drafts immediately cease, but the family noted a great improvement in allergies! Maybe pollen was blowing down the chimney along with the cold air? Or maybe they're allergic to whatever soot or ash the draft carried with it?Whatever - the cost of this gadget will pay for itself with a few less bottles of allergy meds, to say nothing of the cost of however much heat was vanishing up the flue.You do have to be a bit handy, detail-oriented, and flexible to crawl around upside down in your fireplace. Obviously make sure the fire is long out, and the fireplace is as clean as you can reasonably get it first. You're still going to get a bit dirty but it shouldn't be Dickensian. The results will be worth it.

### ⭐⭐⭐⭐⭐ Really worked for me
*by M***. on December 13, 2024*

I have a woodburning pre-fab fireplace that I never use in a family room. The chimney had a chimney cap damper that could be closed but it was damaged last year by a falling branch during a storm and the way the chimney was repaired no longer allowed for a closing cap. So I noticed that the room was much colder than usual even though I had good fireplace doors. The problem was when the furnace kicked on the system would pull cold air into the room through the fireplace doors. The room is now a good 10 degrees warmer in the morning when it's below freezing outside. The flue damper works better than the chimney cap one did.I got the 10 inch round version which fit properly for the purpose but I didn't measure. Just eyeballed the size and found out that having it a little larger than the chimney pipe's hole worked well. The only issue I had was the rod provided is only one foot long so I had to reach up into the chimney to stuff the damper in place. I did have to reach up with a stick to make sure the coverage inside the chimney pipe was smooth without bunching. I didn't need to trim the wool material. The remedy for the short rod was buying a couple of extensions that are also available on Amazon to double the length.

### ⭐⭐⭐⭐ Expensive for what it is, but does the job
*by P***K on November 29, 2022*

The concept here is simple enough - open the damper and stuff this nice insulated wool to stop the cold winter drafts. The sheep wool feels like great quality and it actually does make a significant difference in reducing the draft, but man $45 for some insulation on a stick is a tough pill to swallow.Unfortunately I couldn't find any alternative that looked comparable in the construction, so I suppose you get what you pay for, and in the grand scheme of things this lets me save money from my heating bill on a monthly basis so it probably pays for itself. Still though I feel like I had to do some mental gymnastics to justify the purchase.
