Flue cleaning — professional flue cleaning service

Over time, soot, tar, and other combustion residues accumulate in the chimney flue, reducing draft and increasing the risk of fire. In particular, the creosote deposits produced by burning wood are highly flammable and can cause a dangerous chimney fire if the flue is not cleaned regularly.

A clean flue operates efficiently and ensures that combustion gases are safely vented outside. A dirty or partially blocked flue can cause smoke and carbon monoxide to seep into the living spaces, which is a serious health risk for all residents.

Flue cleaning is especially important if the fireplace is burned with damp wood or if problems with the flue draft have been noticed. A skilled flue cleaning professional uses specialised tools and methods that guarantee a thorough cleaning result.

A professional typically cleans the flue mechanically using sweeping brushes and weights that are pushed through the flue from the roof. This traditional method effectively dislodges soot and other deposits from the flue walls, dropping them into the firebox for collection.

In more difficult cases, such as removing thick creosote buildup, chemical cleaning agents or a rotary saw may be used. Chemical agents soften hardened tar, which can then be removed mechanically. The choice of method depends on the flue material and the degree of soiling.

Modern professionals also frequently use a camera to inspect the flue after cleaning. A camera inspection reveals potential cracks, deterioration, and other damage that may compromise the safety and performance of the flue in the future.

During flue cleaning, the professional always assesses the general condition of the flue. The inspection focuses on the joints of masonry flues, the integrity of brick structures, and any cracks. For steel flues, the tightness of connections and the condition of the pipe are checked.

The condition of the rain cap and flashings at the top of the chimney is inspected at the same time. A damaged rain cap lets water into the flue, which accelerates deterioration and can cause moisture problems. Loose flashings, in turn, expose the chimney structure to the effects of weather.

If significant damage is found during cleaning, the professional provides a recommendation for further action. Minor repairs can often be made during the same visit, but more extensive repair work requires a separate plan and schedule.

Flue condition can be maintained through everyday practices. Always use dry, clean firewood, as damp wood produces excessive soot and tar. Firewood should be dried for at least two years before burning to achieve the optimal moisture content.

Proper use of the fireplace reduces flue soiling. Avoid smouldering conditions where wood burns slowly at a low temperature, as this produces large amounts of creosote. Ensure adequate air supply to the firebox and let the fire burn with a bright flame.

Monitor the flue draft regularly. If smoke does not rise normally or if smoke enters the room from the fireplace, it may be a sign of a blockage or reduced draft. In this case, a professional should be called to assess the situation as soon as possible.
