What is the ground like in West Midlands?

Postcode districts B2, B3, B4 cover Birmingham, a West Midlands town of about 1,160,000 people. We also take enquiries from nearby Smethwick (3 miles), West Bromwich (5 miles) and Halesowen (7 miles).

Parts of West Midlands have clay that can shrink near trees in dry spells. Parts of West Midlands lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across West Midlands, most homes are Victorian terraces, inter-war semis, Black Country industrial housing and large post-war estates.

Repair options we may recommend

Repointing and brick repairs

Eroded joints are raked out and repointed in a mortar suited to the brick, often a lime-based mix on older stacks. Spalled or cracked bricks are cut out and replaced with matched reclaimed or new bricks. On many stacks this, with new flaunching, is all that is needed.

Best for: Upright stacks with weathered joints and some damaged bricks

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

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.
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.
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

How much should I budget for chimney stack repairs in Birmingham?

Guide prices for chimney stack repairs in Birmingham start from about £500 per stack, including VAT, on West Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Can you survey a property in Birmingham?

Yes. We take enquiries from across Birmingham, including B2, B3, B4, and from nearby places such as Smethwick and West Bromwich. Send photos for a free initial view and we will tell you what happens next.

Why do houses in West Midlands crack?

The West Midlands is mostly Mercia Mudstone and glacial till, with the South Staffordshire coalfield under much of the Black Country, where shallow coal and limestone workings are recorded around Dudley, Tipton and Walsall. Only an investigation can say why a particular building has moved.

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.

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.
