About South Wimbledon

South Wimbledon sits between Wimbledon town and Morden, with a quieter residential character than central Wimbledon. Most properties are Victorian terraces or 1930s semi-detached family homes with traditional pitched roofs.

Common work we do here includes chimney repointing, replacing perished felt, full re-roofs on ageing 1930s semis, and EPDM on rear extensions.

What we offer in South Wimbledon

Chimneys are one of the most common sources of roof leaks — and one of the most commonly neglected. A failed chimney can let water in for months before it becomes visible inside, by which time significant damage has often occurred.

Common chimney problems we fix

• Failed pointing — mortar between bricks deteriorating
• Faunching failure — the cement cap on top of the chimney stack cracking
• Loose or cracked chimney pots — usually frost damage
• Lead flashing failure — see our leadwork service
• Stack lean or movement — serious structural concern
• Spalling bricks — face of bricks flaking off
• No flashing or inadequate flashing — common on older properties
• Disused chimney — consider capping or removal

Types of chimney work

Repointing

Removing old, perished mortar and replacing with fresh lime or cement mortar depending on chimney type. Period properties should use lime mortar to match original construction. Expect £30-£60 per linear metre.

Flaunching

The angled cement cap on top of the stack that throws water away from the pot. Renewed as part of most chimney repairs. Should be at least 50mm thick at the pot and angled to shed water.

Pot and cowl replacement

Replacement of cracked or missing chimney pots, plus bird guards/cowls to prevent nesting. Pots available in many sizes and styles.

Partial chimney rebuild

When the top courses of brickwork have failed but the lower stack is sound. We demolish the top, rebuild in matching brick with new flaunching and pots.

Full chimney stack rebuild

For severely deteriorated stacks. Requires scaffold and is a significant job — usually £1,500-£3,000.

Chimney removal

For disused chimneys that are a leak risk or visual eyesore. We demolish the stack, seal the roof opening with matching tiles, and dispose of all debris. Often £1,000-£2,000 depending on access.

Leadwork

Lead flashing replacement (see our Leadwork service for full details). Often combined with chimney repairs.

How to tell if your chimney needs attention

• Damp patch on chimney breast inside the house
• Mortar fragments in the gutter below the chimney
• Visible cracks in the pointing from ground level
• Loose or rattling chimney pot
• Water staining on the bricks
• Efflorescence (white salt deposits) on chimney surface

When to call urgently

• Visible lean or movement of the stack
• Mortar or bricks falling onto the roof or ground
• Large cracks visible from ground level
• Active water ingress around chimney
