Typical buildings in Buckinghamshire: Market-town terraces, 1930s semis in the south, and large late-20th-century estates in Milton Keynes and Aylesbury.

Repair options we may recommend
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
Partial or full rebuild
Where the lean is pronounced or the brickwork is badly decayed, the stack is taken down to sound masonry, often to roof level, and rebuilt plumb with new flashings and flaunching. Original bricks are cleaned and reused where possible to keep the appearance.
Best for: Badly leaning or decayed stacks
What to expect when we carry out chimney stack repairs
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.
Weatherproof and clear
Caps or cowls are fitted where agreed, the roof around the stack is checked for slipped tiles, and debris is cleared from gutters. You receive photos of the finished stack taken from the scaffold, since it is hard to see from the ground.

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 Gerrards Cross?
Guide prices for chimney stack repairs in Gerrards Cross start from about £560 per stack, including VAT, on South East 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 Gerrards Cross?
Yes. We take enquiries from across Gerrards Cross, including SL9, UB9, and from nearby places such as Rickmansworth and Slough. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Gerrards Cross cause cracking?
The Chilterns are chalk with clay-with-flints on the tops, while the Vale of Aylesbury and Milton Keynes sit on Gault, Kimmeridge and Oxford Clays and glacial till. The vale clays are prone to seasonal shrinkage near trees. Only an investigation can say why a particular building has moved.
Can a leaning stack be straightened?
Not by pushing it back, because the brickwork would crack. A slight lean on a sound stack can be restrained so it moves no further. A pronounced lean is fixed by taking the stack down to sound masonry and rebuilding it plumb.
Do I need scaffolding for chimney repairs?
In almost all cases, yes. Safe work on a stack needs a stable platform at stack height, which usually means scaffold. Ladders and roof ladders do not give a safe place to repoint, lift pots or rebuild brickwork.
