Minneapolis Chimney Cleaning FAQ: What Is that Black Stuff in My Chimney?

Monday, May 6th, 2013

When you enjoy the warmth, comfort, and pleasure of a fireplace, you need to make sure that it is in good shape year round. One of the most common question we hear from customers throughout our Minneapolis is concerning the black stuff in your chimney.  Creosote is the name for that tar-like substance that accumulates on the parts of your fireplace and chimney. It’s imperative that you have your chimney cleaned on a regular basis to keep your fireplace running smoothly. Let’s take a look at creosote. For superior Minneapolis chimney cleaning service, call the experts at 2nd Generation Chimneys today!

  • What is creosote? Creosote is that dark brown or black, and often foul-smelling substance that builds up in your chimney.  Its composed of unburned wood particles mixed with condensed flue gases. It is one of the major reasons to have your chimney cleaned. It is toxic and carcinogenic.
  • What causes it? Creosote is typically caused by three major things: incomplete combustion of firewood, cool surfaces within the chimney, and wet firewood. The latter cause is easy to avoid: use only seasoned dry hardwood to build your fires. Depending on your stove or fireplace, there are some things you can do to make sure that your fuel is combusting properly. Use small amounts of wood and stoke often to decrease smoke density in an airtight stove, and make sure you avoid constant smoldering. Burn your fire hot regularly.
  • So what? Our reason for alerting you to creosote is because it poses a potential hazard to the safety of your home. While creosote tends to affect wood stoves more than fireplaces because the former’s exhaust gases tend to be cooler, creosote is an issue in any wood-burning device. As creosote accumulates within the chimney, it can become thick and begin to close in on the draft opening. When such accumulations thicken enough, they can actually ignite; chimney fires can disturb the masonry or metal chimney, but they can also lead to house fires when the framing heats up enough.

We hope this gives you some idea about creosote. For comprehensive Minneapolis chimney cleaning, call 2nd Generation Chimneys today!

Why Most Prefabricated Fireplaces in Cambridge Cannot be Installed Using the Existing Chimney System

Thursday, March 22nd, 2012

If you are looking to add a charming touch to your home, or just supplement your current heating system, you may be considering installing a fireplace. Since building a new fireplace is often costly and requires a lot of masonry work, many people are opting for prefabricated fireplaces instead.

Prefab fireplace units are nice, because they are convenient, they look charming and they work well. However, some people assume that because they already have a chimney in their home from a previous system, adding a prefab system will be easier and not require a new chimney. Generally, though, this is not true.

Most prefabricated fireplaces are sold as a unit along with an accompanying chimney, and they often will now work with another chimney system. There are a few reasons for this, such as:

  • Rigorous fireplace inspections and testing is a must for each home to ensure that they are safe to use. This testing is done along with the included chimney, so both are rated as safe together. The fireplace is not necessarily tested to be safe with any other configuration.
  • The specifications for air space and insulation in a fireplace are exacting, because of the volatile nature of the combustion process. Because a prefabricated fireplace and chimney are engineered to work together, you can be sure they meet the proper specifications.
  • The chimney and fireplace have been designed to work together for maximum efficiency, so any other setup could affect the performance of your fireplace and therefore the warmth of your house.
  • Because of the necessary clearance measurements mentioned above, wood is kept a certain specified distance away from the chimney. If a prefabricated fireplace is used with a different chimney, this clearance may be too short, which can cause chimney fires or other unsafe conditions.

Even with all this in mind, a prefabricated fireplace may still be the best option for you. It is just important to know up front that trying to save money be using an existing chimney system will not work and you are better off purchasing the whole bundle as sold.  If you have any questions about your fireplace please call 2nd Generation Chimneys.
