Why Chimneys Leak

The Most Overlooked Source of Roof Leaks

Chimneys are one of the most exposed parts of any roof. They project above the roof line, are subject to wind from all directions, and experience significant thermal movement as they heat and cool. Over time, the mortar joints between bricks deteriorate, lead flashings lift and crack, and chimney pots become loose or damaged.

The result is water ingress — often appearing as damp patches on the chimney breast inside the property, sometimes several metres away from the actual source of the leak. Many homeowners spend money treating damp internally without realising the chimney is the cause.

We carry out a thorough inspection of the chimney stack, flashings, and surrounding roof covering to identify all sources of water ingress. We then provide a written report and a fixed-price quote to put it right.

Signs Your Chimney Needs Attention

  • Damp patches on the chimney breast inside
  • White staining (efflorescence) on chimney brickwork
  • Crumbling or missing mortar visible from ground
  • Loose or leaning chimney pots
  • Cracked or lifted lead flashings
  • Loose bricks in the chimney stack
  • Water stains on ceilings near the chimney
  • Musty smell from the fireplace

What We Do

Chimney Repair Services We Offer

Chimney Repointing

The mortar joints between chimney bricks deteriorate over time due to weathering, frost, and thermal movement. Crumbling or missing mortar allows water to penetrate the stack, causing damp inside the property. We rake out failed mortar and repoint using a suitable lime or sand-and-cement mix to match the existing finish.

Lead Flashing Repair & Replacement

Lead flashings seal the joint between the chimney stack and the roof covering. They are one of the most common causes of roof leaks when they fail. We repair lifted, cracked, or corroded flashings and replace them with code-quality lead or modern alternatives where appropriate.

Chimney Stack Rebuilding

Where a chimney stack has deteriorated beyond repair — due to severe weathering, frost damage, or structural movement — we carry out partial or full rebuilds. We match the existing brickwork as closely as possible and ensure the rebuilt stack is properly flashed and weatherproofed.

Chimney Pot Replacement

Cracked, broken, or missing chimney pots allow water to enter the flue and can cause damp in the chimney breast. We replace damaged pots with matching or complementary alternatives and ensure they are properly bedded in mortar.

Chimney Cowl & Cap Fitting

Chimney cowls and caps prevent rain, birds, and debris from entering unused flues. We supply and fit a range of cowls and caps to suit all chimney types, including anti-downdraught cowls for chimneys that are still in use.

Chimney Damp Investigation

Damp patches on chimney breasts inside the property are often caused by failed flashings, crumbling repointing, or a cracked chimney pot. We carry out a thorough inspection to identify the source of the problem and provide a written report with our recommended solution.

FAQs

Chimney Repair Questions Answered

How do I know if my chimney needs repointing?

Signs that your chimney needs repointing include crumbling or missing mortar visible from ground level, damp patches on the chimney breast inside the property, white staining (efflorescence) on the brickwork, or loose bricks. We offer free chimney inspections with all repair quotes.

How much does chimney repointing cost in Cambridgeshire?

The cost depends on the size of the chimney, the extent of the repointing required, and access. A typical chimney repoint can range from £300–£800. We always provide a free written quote before any work begins.

Do I need scaffolding for chimney repairs?

For most chimney repairs, scaffolding or a tower scaffold is required to work safely at height. We arrange all necessary access equipment as part of the job — the cost is included in our quote.

Can you repair a chimney on a listed building?

Yes — we have experience working on historic and listed properties. We use appropriate lime mortars and traditional materials where required, and can advise on any planning or conservation area considerations.

My chimney is no longer in use — do I still need to maintain it?

Yes. Even unused chimneys need to be kept weathertight to prevent damp. We recommend fitting a chimney cap or cowl to seal unused flues, and ensuring the stack and flashings are in good condition.
