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

  1. Check what is below

    We ask whether any chimney breasts have been removed, and check the loft and rooms below for cracking. If a breast has gone without proper support, we recommend an independent chartered structural engineer before any stack work.

  2. 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.

  3. 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.

Is it time for chimney stack repairs? Common signs

  • Chimney pots that are loose, tilted or cracked at the base
  • Cracked or missing flaunching around the top of the stack
  • Bits of brick, mortar or render landing in the garden or gutter

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

How much will chimney stack repairs cost in Sunbury-on-Thames?

Guide prices for chimney stack repairs in Sunbury-on-Thames 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 cover Sunbury-on-Thames?

Yes. We take enquiries from across Sunbury-on-Thames, including KT12, TW16, TW17, and from nearby places such as Ashford and Weybridge. Send photos for a free initial view and we will tell you what happens next.

Is the ground in Surrey prone to subsidence?

North Surrey sits on London Clay, the south on Weald Clay, with chalk along the North Downs and sands in the west. Large gardens with mature trees on clay make seasonal subsidence a familiar problem. Only an investigation can say why a particular building has moved.

Is a leaning chimney dangerous?

A leaning chimney can become dangerous, because stacks are heavy and stand high above the roof. A slight, long-standing lean may be stable for now, but a lean that is worsening, or loose bricks and pots, should be looked at quickly. Keep people away from below if anything looks loose.

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.
