125mm flexible flue liner choked with creosote and tar buildup from burning unseasoned green wood — chimney fire risk, NACS registered sweep inspection, Allchimney Sweeps, Harold Wood

125mm flexible liner choked with creosote and tar — burning unseasoned green wood, Harold Wood. Flue cleaned, condition reported, customer advised on fuel quality.

From the Job — Harold Wood

125mm Liner Choked — Harold Wood

This 125mm flexible flue liner was choked with creosote and tar from burning unseasoned green wood — Harold Wood. The homeowner had no idea the flue was in this condition. This is the most dangerous outcome of burning wet wood: the tar and creosote build up silently inside the liner until the restriction is severe enough to cause smoke spillage, poor draw, or chimney fire.

Harold Wood properties — particularly the inter-war semis around the station and along the main roads — often have original chimney stacks lined in more recent years with flexible stainless steel liners. These liners are excellent when maintained correctly, but they must be swept annually and the fuel quality must be right. Wood must be seasoned for a minimum of two years before burning.

Harold Wood — FAQ

Chimney Sweep Harold Wood — Common Questions

Do you sweep chimneys in Harold Wood?

Yes. Harold Wood is a regular part of our working week. We cover Harold Wood, Gidea Park Romford, Harold Hill and the wider Havering and Brentwood area. Call 01708 956086 or WhatsApp for a same day response.

What wood should I burn in my stove in Harold Wood?

Only properly seasoned, dried hardwood — seasoned for a minimum of two years. Better still, kiln-dried hardwood with a moisture content below 20%. Never burn green wood, softwood, treated wood, chipboard or household waste. Look for the Ready to Burn logo when buying logs locally.

My stove draws fine — do I still need a sweep?

Yes. As this Harold Wood job shows, a stove can appear to draw normally while the liner builds up with tar and creosote. Annual sweeping removes the buildup before it becomes a fire or CO risk. The NACS certificate confirms the flue is clear at the time of each sweep.

How close is Harold Wood to Brentwood — do you cover both?
