The professionals here at All Year Chimney Sweeps and Repairs are dedicated and committed to providing all our valued clients with top of the line services, quality products, and yes, even insight and advice when needed. We are often approached by clients with a common question regarding chimneys – What is the Best Way to Block my Chimney? We feel that the question being asked should more appropriately be “Is it Safe to Block my Chimney?” With that said, our experts here at All Year Chimney Sweeps and Repairs feel it is not entirely safe to block your chimney flue and, therefore, we would suggest to our clients not embark on such a permanent task.
Is it Safe to Block a Chimney?
Before homeowners decide to block off a chimney we strongly suggest you take the following into consideration and take it seriously. When you block a chimney flue you cause premature deterioration of the masonry because blocking it does not allow it to breathe any longer. Bricks and mortar that do not have air flowing through them certainly do not fare well over time.
If you have a fireplace that you are contemplating blocking off there is one primary problem that you should be concerned about. If everyone is not aware that the flue is blocked and someone attempts to build a fire lacking this knowledge, then, though it is not desperately dangerous, it will indeed cause your home to fill up with smoke rather quickly. Further, in this fireplace scenario, if there happens to be gas logs in the fireplace, then you present with a real danger, especially the danger of CO poisoning, which is why we strongly advise that it is not practical or even safe to block a chimney or chimney flue whether a temporary or permanent blocking.
Despite our words of warning and our safety concerns, we are aware that there are clients who will still want to block off their unused chimney, so we offer the following advice depending upon the reason why you want to block your chimney – are you trying to alleviate the draft or do you simply want it closed because it is unused?
If your concern is the simple fact that you want to stop the draft that is coming in through the flue, then we strongly suggest you opt for a temporary solution to this problem and simply install a top sealing damper. By taking this approach, if you ever change your mind and want to use the fireplace, or if you sell the house and the next owner wants to use the fireplace, you will still have the option to reopen the flue and use it. This is a ‘temporary’ solution to closing off your chimney flue and is certainly both practical and safe.
There are certainly specialized steps you can take to permanently close off your chimney but, as we have noted above, we think it would be more practical and certainly safer if you were to choose the simple temporary solution suggested above. We have found, more often than not, when people opt to permanently block off their chimney somewhere down the road they find themselves asking themselves why they chose a permanent rather than a temporary blocking. Certainly there is always a chance that you may want to utilize the fireplace at a later time in life, not to mention that if you try to sell your home, having a working chimney and fireplace enhances the value of the home and usually makes for a good selling point.
If you are bothered by a constant draft, or simply just do not use your fireplace, then the professionals here at All Year Chimney Sweeps and Repairs think it best you opt for a temporary solution to this problem at hand and leave open the option of unblocking a chimney later on in life for one reason or another.
