A chimney stack that is leaning, has spalled brickwork, or has a crumbling mortar bed beneath the pot is a structural risk, not just a cosmetic problem. We rebuild chimney stacks from the lead line upwards or from the roof level depending on the extent of the damage. All our chimney work is carried out from a properly erected scaffold.
A chimney rebuild is needed when the brickwork or mortar has deteriorated beyond what re-pointing or localised repairs can fix. This can be caused by frost damage, water penetration, settlement, or simply age. In Ipswich, many older properties in areas like St Margaret's, Westgate, and the Victorian terraces around Nacton Road have chimney stacks that have never been properly maintained and are now in poor structural condition.
The work typically involves erecting scaffold to give safe working access, then dismantling the stack down to a sound course of brickwork, usually at or just above the lead flashing line. We rebuild using matching brick where possible, which matters on period properties, set in a frost-resistant mortar mix. The flaunching, which is the sloped mortar bed that holds the chimney pot, is made fresh, and new lead flashing is fitted at the base. Pots can be re-used if they are undamaged or replaced if they have cracked.
Chimney stacks sit at the highest point of the house and are fully exposed to the weather on all four sides. Loose or leaning stacks can drop masonry onto the roof or into the street, and a stack with open joints will push water into the chimney breast inside the house. Getting scaffold up and sorting the problem properly is always cheaper than repairing ceiling and wall damage from years of water ingress.
We photograph the chimney from scaffold before and after work so you can see exactly what was done. Most chimney rebuilds take one to three days once the scaffold is in place, depending on the height and extent of the work.
A partial chimney rebuild in Ipswich, from the flashing line upward, typically costs between £800 and £2,000, with full stack rebuilds from roof level running higher depending on height and access.
