Chimney stack repairs in Bordon

On older houses around Bordon, many stacks lean slightly away from the prevailing weather. That is usually sulphate attack in the mortar, and the repair depends on how far the stack has moved and how sound the brickwork still is.

How do local ground conditions affect chimney stack repairs in Bordon?

With roughly 21,000 people, Bordon spans postcode districts GU35 in Hampshire. Neighbouring towns we cover: Alton (5 miles), Haslemere (7 miles) and Farnham (7 miles).

Much of Hampshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. Across Hampshire, most homes are Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.

What happens during chimney stack repairs, step by step?

  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. 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.

  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.

What to look for before calling about chimney stack repairs

  • Bits of brick, mortar or render landing in the garden or gutter
  • Cracked or missing flaunching around the top of the stack
  • A stack visibly leaning when you look along the roof ridge

How we usually approach chimney stack repairs

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

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

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.

Questions about chimney stack repairs in Bordon

What is the price of chimney stack repairs in Bordon?

Guide prices for chimney stack repairs in Bordon 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 Bordon?

Yes. We take enquiries from across Bordon, including GU35, and from nearby places such as Alton and Haslemere. Send photos for a free initial view and we will tell you what happens next.

Does the ground around Bordon cause cracking?

Central Hampshire is chalk, while the south around Portsmouth, Southampton and the New Forest fringe and the north-east around Farnborough sit on London Clay, Reading Beds and other clays and sands. The clay areas see seasonal movement 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.
