Why Does Your Chimney Need Sweeping?  

Over time, chimneys accumulate soot, ash, and creosote, which can lead to:  

🔥 Chimney fires – Over 3,000 chimney fires occur in the UK each year, many caused by creosote buildup.  

⚠ Carbon monoxide poisoning – A blocked chimney can trap dangerous gases inside your home.  

💨 Poor heating efficiency – A dirty chimney reduces airflow, making your stove or fire burn inefficiently.  

🐦 Blockages from birds, nests, and debris – Jackdaws, pigeons, and squirrels often nest in chimneys, causing ventilation problems.  

Regular sweeping ensures safety, efficiency, and compliance with UK regulations.  

Step-by-Step Guide to a Professional Chimney Sweep  

Step 1: Preparing Your Home for a Chimney Sweep  

Before our arrival, we recommend:  

✔ Clearing the area around the fireplace to provide easy access.  

✔ Covering furniture nearby to protect it from dust (though we use protective sheets).  

✔ Not using the fire for at least 12 hours before the appointment to ensure the chimney is cool.  

We always ensure your home remains clean and dust-free throughout the process.  

Step 2: Inspecting the Chimney and Fireplace  

Before starting, we perform a visual inspection of the chimney and appliance to check for:  

✅ Soot and creosote buildup  

✅ Cracks or damage in the flue liner  

✅ Bird nests or blockages  

✅ Signs of damp or leaks  

If we find any major issues, we’ll advise on the necessary repairs or maintenance.  

Step 3: Setting Up Protective Equipment  

To ensure a mess-free sweep, we use:  

✔ Protective dust sheets to cover the surrounding area.  

✔ A powerful vacuum system with HEPA filters to capture fine dust.  

✔ Sealing methods to prevent soot from escaping into the room.  

This ensures your home remains clean throughout the process.  

Step 4: Sweeping the Chimney  

We use modern chimney sweeping techniques to thoroughly clean your flue:  

Traditional Brush and Rod Method  

- A series of flexible rods with specially designed brushes are inserted into the chimney.  

- The brush is worked up and down to dislodge soot, tar, and debris.  

Rotary Power Sweeping  

- In some cases, we use a rotary power sweep system, which spins a high-speed brush for deeper cleaning.  

- This method is particularly effective for heavy creosote buildup in wood-burning stoves.  

All soot and debris are collected safely, preventing mess in your home.  

Step 5: Vacuuming and Final Clean-Up  

Once the chimney is clean, we:  

✅ Use an industrial vacuum to remove any remaining soot.  

✅ Check the fireplace and hearth area, ensuring everything is spotless.  

✅ Dispose of debris safely.  

We take pride in leaving your home just as clean as we found it!  

Step 6: Performing a Smoke Draw Test  

To ensure the chimney is functioning properly, we conduct a smoke draw test:  

🔥 A small smoke source is placed inside the fireplace.  

💨 We check whether the smoke flows smoothly up the chimney or if there are any restrictions.  

If the smoke fails to exit properly, it may indicate a blockage, poor airflow, or structural damage.  

Step 7: Providing a Professional Report and Advice  

Once the sweep is complete, we provide:  

📜 A full chimney sweeping certificate (for insurance & landlord requirements).  

✅ Advice on ongoing chimney maintenance.  

🔥 Recommendations for improving efficiency, such as using the right fuel.  

We also offer bird guard and cowl installations to help prevent future blockages.  

How Long Does a Chimney Sweep Take?  

⏳ A standard chimney sweep usually takes 30-60 minutes, depending on:  

✔ The level of soot and creosote buildup  

✔ Whether there are bird nests or blockages  

✔ The type of chimney and appliance  

For heavily used chimneys, more time may be required for a deep clean.  

How Often Should You Have Your Chimney Swept?  

According to the National Association of Chimney Sweeps (NACS):  

| Fuel Type | Recommended Sweeping Frequency |  

|--------------|--------------------------------|  

| Wood-burning stoves & open fires | At least 4 times a year (when in use) |  

| Smokeless fuel fires | At least once a year |  

| Coal-burning appliances | Twice a year |  

| Gas & oil appliances | Once a year (if chimney is in use) |  

If you use your fireplace frequently, additional interim sweeps may be needed.
