Tar Removal

Our Chimney Tar Removal Approach

We use industry approved chemical treatment which we supply to you in sachets for use in your affected chimney. The period of treatment is dictated by the nature, condition and stage of the tar within the chimney. Once Treatment is completed over the prescribed period of time, we then arrange a second appointment to remove the tar dislodged by this method.

What is Creosote?

Creosote is a flammable and corrosive substance that can build up on the walls of your fireplace and chimney. Creosote forms when unburned wood particles, fly ash and other volatile gasses combine as they exit the chimney. If there’s a poor draft, these unburned particles and gasses can condense and build up on the walls of your chimney. Over time, these e or soot build ups can become a danger as they can potentially result in a chimney fire.

Causes of Chimney Creosote Problems

Smoke, or better termed, flue gas, releases by the initial fire, or primary combustion. Burning wood, no matter when releases pollutants in the form of gasses and particulate matter. Flue gas, comprised of steam and vaporized but unburned carbon based byproducts (vaporized accumulation). If smoke exiting the chimney is cools to below 250 degrees Fahrenheit, the gasses liquefy, combine, and solidify to form that tar compound. A flue too large for the woodburning appliance may increase the likelihood that creosote will build up. Restricted air supply, unseasoned or rain-logged wood, and cool surface flue temperatures also encourage creosote to build up.

Creosote Stages:

Condensation: In an attempt to save fuel, many people reduce the amount of air entering the combustion chamber, causing the appliance to smolder. This has serious side effects. Smoke then cools as it rises in the chimney, not having enough heat energy to escape the stack. The flue gas then condenses on the inside of the chimney and the sap/resin turns into creosote.

This swollen creosote is very fragile and brittle. It can block the flue and cause tremendous smoking problems.Not uncommon if you’ve experienced a chimney fire.

Liquidation: This sap/resin turns liquid and can seep into mortar joints or cracks in the flue tiles. The corrosive property held by creosote destroys masonry work and jeopardizes the life of your chimney.

Solidification: As temperatures fall and rise within the chimney, causing the heating and cooling of the creosote. This quickly enables build-up, reducing the amount of space the flue gas has to exit the chimney and, in extreme cases, blocking the flue completely. This build up can look like tar and is frequently termed “tar build-up.

Fragile State Creosote: When the solid creosote is burned, all volatile oils are removed leaving a residue that appears very similar to honeycomb which is crisp and easy to sweep from chimneys.

Often creosote will accumulate at the top of the chimney over longer periods of being unattended to during the events.

Creosote Glazing

Glaze forms in the solidification stage and occurs when new layers of creosote build so quickly that the layers below it have no time to dry. These fresh layers then insulate previous deposits so it eventually solidifies creating the rock-like substance known as glaze.
