Chimney Sweeping Frequently Asked Questions

1) How often do I need to sweep my chimney?
Many factors will affect the time span needed between sweeping - Type of fuel, regularity of use, flue efficiency and others -  If you use your chimney regularly in the winter season, we would recommend that you have your chimney swept at least once a year. The HETAS website for solid fuel standards has more specific guidelines for particular circumstances.

2) Why should I regularly sweep my chimney?

Chimney sweeping improves the natural flue draft, therefore your fire burns hotter, more consistently, and more efficiently. Regular sweeping lessens the risk of partial or total flue blockage which can result in the build up of smoke fumes and dangerous carbon monoxide gas. There is also much less chance of a chimney fire occurring (where excessive soot catches fire). Gas appliances should be 
serviced and tested to ensure a good flue-pull due to the increased dangers of fumes.

3) Is sweeping my chimney a dirty process?
No! Our tried and tested method will ensure a clean service. Please visit The Process page.

4) How long does each sweep take?
Most Jobs take between 30 to 45 minutes. However, awkward jobs, such as bird nests removals can take from a few more minutes to several hours. Don't worry, if a job will take longer than expected, we will always inform you before finishing the sweeping process.

5) Which fuel creates more soot?
Coal is by far the 
 for soot deposits. Smokeless coal is comparatively clean, but not soot free.Wood leaves a tarry resin which dries hard(It's the natural oil present in all wood to a greater or lesser extent).All solid fuels create soot, hence the need to sweep your chimney regularly.

6) What factors affect my fire?
There are many! Type of flue, internal ventilation, the width and height of your chimney, weather conditions, chimney terminal type, internal cross-sectional area, geographical position of your house, type of stove/fireplace and many other factors. After almost 25 years of experience, we can certainly say that chimneys can be and are, QUIRKY!

7) What are the most common chimney problems?

A) Blockages! - Usually due to excessive soot, bird's nests or a structural defect. The first two can be cured by a chimney sweep.  Structural defects might require a reputable builder or chimney lining  company.
B) Incorrect  terminal on top of chimney pot! - Usually easily fixed by swapping to a correct terminal.
C) Back drafting (when the smoke is sucked into the room and not up the chimney)! - This can be as a result of any or several factors above that affect flues.
D) Chimney setting on fire! - The result of a build up of soot in the chimney due to lack of maintenance.
With most chimney  problems the first step is to call a chimney sweep. This will either sort the problem out, or at least ascertain the nature and extend of the problem.
