Chimney Repairs in Eastleigh

Eastleigh's SO50 area is dominated by dense Edwardian terraces and inter-war semis built for railway workers and their families. Many retain their original chimney stacks, and the tell-tale signs of age are now showing across the town — crumbling mortar joints, failed flaunching, loose pots and damp chimney breasts inside.

We carry out all types of chimney work across Eastleigh, Chandler's Ford, Bishopstoke and the wider SO50 area.

Repointed to match the brickwork, not just patched over the top.

How we repair your chimney

  1. Inspect from heightThe stack is checked from scaffold or a tower — mortar joints, flaunching, pots and lead flashing all assessed before any work starts.
  2. Rake out and repointPerished mortar is raked out and the stack repointed, using a mortar mix matched to the age of the brickwork.
  3. Renew flaunching and potsCracked flaunching is renewed around the pots, and any loose or damaged pots are re-bedded or replaced.
  4. Lead flashingThe stepped lead flashing and soakers where the stack meets the roof are checked and renewed where needed to keep it watertight.

What we cover

Chimney repointing

On Eastleigh's Edwardian and inter-war housing, mortar joints in chimney stacks have often completely weathered out or been incorrectly patched with hard cement at some point. We remove failed pointing and repoint to the correct specification — using lime-based mortars where appropriate to protect the original brickwork from damage.

Lead flashing repair & replacement

Failed or lifting lead flashing around the chimney base allows water to track straight into the roof space. Many Eastleigh properties have never had their original lead flashing replaced. We re-dress lifting sections or supply and fit new code-grade lead sheet where the existing material is beyond recovery.

Chimney pot repair & replacement

Cracked, displaced or missing chimney pots allow rain and birds into the flue. We replace individual pots or fit cowls and caps to seal unused flues — a common requirement on Eastleigh properties where gas central heating has been installed and the original fireplaces are no longer in use.

Flaunching repair

Flaunching failures are among the most common chimney issues we encounter on Eastleigh's older housing. The mortar bed holding chimney pots cracks over time and allows pots to become loose or fall. We remove and re-lay all failed flaunching rather than patching over existing cracks, which is a short-term fix at best.

Full chimney stack rebuild

Where a chimney stack is beyond economical repair — or where structural movement has compromised the brickwork — we take it down and rebuild using matching brick. We can also reduce stack height or carry out full removal where the chimney is redundant and causing ongoing maintenance issues.

Chimney inspections

Not sure of the condition of your chimney? We carry out thorough inspections covering all elements — pointing, flaunching, lead flashing, pots and stack condition — and give you a plain-English written assessment so you can decide how to proceed.

Common questions

Why do so many Eastleigh properties have chimney problems?
Eastleigh grew rapidly as a railway town from the late Victorian era through to the inter-war period, which means a large proportion of the SO50 housing stock is now over 80 to 100 years old. Original chimney stacks on Edwardian and 1920s–1930s terraces were built with lime-based mortars that, in many cases, have either weathered out completely or been incorrectly repaired with hard cement that has since caused cracking. Both conditions lead to water ingress and require proper assessment before any repair work begins.
What is flaunching and how do I know if mine needs replacing on my Eastleigh property?
Flaunching is the sloped mortar bed that sits at the top of the chimney stack and holds the chimney pots in position. On Eastleigh's older Edwardian and inter-war housing, flaunching has often been patched multiple times over the decades and can become cracked, hollow-sounding or visibly broken away from the pots. Signs that it needs attention include pots that rock or shift, visible cracks running across the mortar bed, or chunks of mortar found in the gutters after windy weather. We remove failed flaunching completely and re-lay it properly rather than patching over existing cracks.
I have an Edwardian terrace in Eastleigh — do you use lime mortar for the repointing?
For genuinely old Edwardian and Victorian brickwork in Eastleigh we always recommend a lime-based mortar rather than a modern cement mix. Hard Portland cement mortars are stronger than the bricks themselves on older properties, which means that when the mortar eventually moves or cracks, it is the bricks that fracture rather than the joints — causing far more expensive damage. We assess the existing mortar composition and the age of the brickwork before specifying the correct mix for your chimney.
Can you repair a chimney on a mid-terrace property in Eastleigh where access is difficult?
Yes. Mid-terrace chimney repairs are something we carry out regularly across Eastleigh's terraced streets. Access arrangements — whether scaffold, tower, or in some cases a ladder — depend on the chimney height and the extent of the work. We confirm the access method and any scaffolding costs as part of the free quote so there are no surprises.
