Chimney stack repairs in Brentwood
For terraced streets in Brentwood, stacks are often shared between neighbours. We plan scaffold access and the work so both sides know what is involved, and we can price the stack as a whole if you want to split the cost.

Is Essex prone to ground movement?
We cover Brentwood and its postcode districts CM13, CM14, CM15, part of Essex, with a population of roughly 53,000. Neighbouring towns we cover: Billericay (5 miles), Havering (5 miles) and Basildon (7 miles).
Shrinkable clay is widespread in Essex. Ground movement here is more often linked to soils, drains and trees than to mining. Across Essex, most homes are Victorian terraces, 1930s semis and bungalows, and large post-war new-town estates in Basildon and Harlow.

Repair options we may recommend
Flaunching and pot resetting
Old cracked flaunching is broken out, pots are lifted and reset or replaced, and new flaunching is formed to a fall so water runs off. Unused flues can be capped with ventilated caps, which keeps rain out while letting the flue breathe.
Best for: Loose pots and cracked mortar at the top of the stack
Stack restraint or strapping
A stack that has leaned slightly but is otherwise sound can be restrained with stainless straps or ties fixed back to the roof structure or the gable. This stops further movement without taking the stack down, and is often combined with repointing.
Best for: Slightly leaning stacks with sound brickwork
What to expect when we carry out chimney stack repairs
Look from the ground
Photos from the street and garden, ideally with a zoom, show us the lean, the pots, the flaunching and the state of the pointing. Damp patches inside are worth photographing too, as they help trace the route water is taking.
Scaffold to the stack
Safe access is set up with a working platform around the stack. On terraces we may need to agree access over a neighbour’s roof, and a council licence is arranged where the scaffold stands on the pavement.
Repair, restrain or rebuild
The agreed work is carried out: repointing, new flaunching and pots, restraint, or taking the stack down and rebuilding it. Lead flashings where the stack meets the roof are checked and renewed if needed.

Rules for chimney stack repairs in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Your chimney stack repairs questions
What is the price of chimney stack repairs in Brentwood?
Guide prices for chimney stack repairs in Brentwood start from about £525 per stack, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out chimney stack repairs in Brentwood?
Yes. We take enquiries from across Brentwood, including CM13, CM14, CM15, and from nearby places such as Billericay and Havering. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Brentwood cause cracking?
London Clay covers much of south and central Essex and boulder clay much of the north, making it one of the counties most affected by clay shrinkage in dry summers. Street and garden trees close to houses add to the risk. Only an investigation can say why a particular building has moved.
Should I remove my chimney stack instead of repairing it?
It depends on whether you use the flue, the stack’s condition and how it relates to the house next door. Taking a stack down below the roofline changes the structure and the roof, and on a terrace it can affect your neighbour. We can price both options.
What if a chimney breast below has been removed?
Where the breast has gone but the stack is still on the roof, how that stack is now held up is a structural question. Cracking in nearby ceilings or a dropped stack are warning signs. An independent chartered structural engineer should assess it before any repair, and we can arrange one.
