⚠️ TWO CHIMNEYS. TWO PROPERTIES. LESS THAN 48 HOURS APART.
Both of these customers believed they were doing the right thing by sweeping their own chimneys.
Unfortunately, what we found tells a very different story.
The photographs show significant creosote deposits inside the flues. This isn’t simply a bit of soot that has been missed. Creosote can be highly combustible, and when deposits are allowed to build up, the potential consequences can be serious.
🔥 Increased risk of a chimney fire
🔥 Extremely high temperatures if the deposits ignite
🏠 Potential damage to the flue, chimney and surrounding building structure
💨 Restriction of the flue and reduced performance
⚠️ Increased risk of dangerous combustion gases not being drawn away correctly
💷 And, as both customers have unfortunately discovered, potentially expensive remedial treatment
A chimney may look clean from the fireplace, but that doesn’t mean the entire flue is clean or safe.
A professional chimney sweep isn’t simply pushing a brush up the chimney. We are looking at the condition of the flue, the deposits being removed, signs of tar and creosote, potential blockages and other warning signs that may require further investigation.
Both of these properties are now undergoing intensive creosote treatment to remove the deposits properly — a considerably bigger and more expensive job than routine chimney maintenance.
There is absolutely nothing wrong with homeowners wanting to look after their own properties.
But sometimes DIY can give a false sense of security.
These two chimneys are a very good example of why having your chimney properly swept and inspected matters.
If you’re burning wood or solid fuel, don’t assume that because a brush has been up the chimney, the chimney is clean.
Get it swept properly. Get it checked properly. And know what you’re burning into.
