Block a Chimney

Problems with chimneys can occasionally become so infuriating for homeowners that they want more than just to cap a chimney; instead, they want the chimney to be demolished or removed entirely, or at the at least, they ask us to totally seal off a chimney.

Most of the time, the problem is caused by leaks in the chimney or by a draft, which is undesired chilly air coming from the fireplace. Regardless of the reasons that lead them there, a lot of homeowners frequently arrive at this verdict. When homeowners reach the point where they are considering chimney blockers as a solution to the problems produced by their homes’ chimneys, it is safe to assume that they have already tried everything else and have reached an extreme level of aggravation with the situation.

Before we go into the specifics of how to block a chimney, it is important that you understand the potential consequences of removing a chimney and fireplace from a home.

A Guide to Weatherproofing Your Fireplace and Chimney
Instead of asking HOW to seal a fireplace and chimney, you might consider asking WHY you SHOULD NOT seal the fireplace and block the chimney. This section will explain just that. A chimney is essentially an open doorway that leads from the inside of a house to the exterior of the building. If a route is blocked off, it transforms into a container in the same way as a window or door leading to the outside does.

With a chimney, half of it is subjected to the temperatures within, and the other half is subjected to the temperatures outside. These varying temperatures frequently cause the moisture in the trapped air to condense, becoming a liquid on the interior surfaces of the chimney when combined with a fireplace that has been walled off and a chimney that has been sealed.

As more air leaks in so does more moisture. A chimney that is closed off or obstructed will in fact let more water into the house than it did before it was closed off or barred. Problems with odor, mold, and water damage will result from this action.

The act of sealing a chimney actually creates more issues than it resolves.
When a fireplace and chimney are sealed off, water will constantly collect inside the flue of the chimney. Do not, under any circumstances, attempt to seal off a chimney or fireplace; doing so will result in a flue that is clogged with condensation problems.

Even if your fireplace is sealed off completely from the outside air, you could still wind up with “hidden” water problems. However, these issues can only be concealed for so long! We assure you that there are alternatives to blocking or sealing a chimney and fireplace, and they are more preferable.

Alternatives to the Persistent Problem of Cold Air Flow
A living room may become inhabitable if cold air is forced out of the chimney and down the flue from the fireplace. There are short-term fixes available for the problem of cold air leaking into and out of the chimney.

The fireplace is perhaps the feature that homeowners despise the most, despite the fact that the majority of people adore having one. However, for those who have to deal with chilly drafts and a smell that permeates the space, the fireplace can be a real pain. There is another option available to us. There are some stopgap measures you may take that, if carried out correctly, will provide you with some respite in the near term even though you won’t be able to cover up the fireplace or block off the chimney.
