Chimney Repairs in Fareham

Fareham's PO15 and PO16 area runs from Victorian terraces in the town centre and Portchester through to post-war estates in Crofton and Titchfield Common. Many of these properties carry original chimney stacks that have never been overhauled.

Crumbling pointing, failing lead flashing and deteriorating flaunching are the issues we deal with most across the 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

Crumbling or missing mortar between chimney brickwork is one of the most common causes of water ingress. We remove failed pointing and repoint using the correct mortar mix for the age of the property — particularly important on Fareham's older Victorian stock where hard cement mortars can cause brick damage.

Lead flashing repair & replacement

Failed or lifting lead flashing around the chimney base is a primary cause of roof leaks. Many Fareham properties have original lead work that is now decades old. We re-dress or fully replace lead flashing using code-grade lead sheet for a permanent, weathertight seal.

Chimney pot repair & replacement

Cracked, displaced or missing chimney pots allow rain into the flue. We replace individual pots or fit chimney cowls and caps to prevent water and bird ingress — a common problem on Fareham's exposed chimney stacks close to the coast.

Flaunching repair

The flaunching — the mortar bed holding the chimney pots in place — cracks over time, allowing pots to become loose and fall. We remove and re-lay flaunching to secure pots correctly, ensuring they cannot shift or topple in high winds.

Full chimney stack rebuild

Where a chimney is beyond economical repair, we take it down and rebuild it in matching brick. We can also reduce chimney height or remove stacks entirely where no longer needed — common on post-war Fareham properties where chimney breasts have been removed internally.

Common questions

My Fareham Victorian terrace has original chimney stacks — are they worth repairing or should I remove them?
In most cases, repairing is far more cost-effective than removal — and retaining original stacks generally preserves the character and value of Victorian terraces in areas like Fareham town centre and Portchester. Where the stack is structurally sound but has failed pointing or flaunching, a targeted repair will give you many more years of service. We will give you an honest assessment of the stack condition and the options available.
I have old lead flashing around my chimney that keeps lifting — is this a common problem in Fareham?
Yes, this is a very common issue across Fareham's older housing stock, particularly in the PO15 and PO16 postcode areas where many properties have original lead work that has never been replaced. Lead flashing lifts when the mortar joints it is tucked into erode or when the lead itself becomes brittle and loses its seal. We re-dress lifting flashings where the lead is still in reasonable condition, or replace the full run with new code-grade lead where needed. Either way, it is a contained job that resolves the leak.
How does the coastal proximity around Fareham affect chimneys?
Fareham's position close to Portsmouth Harbour and the Solent means chimney stacks in the area are exposed to salt-laden air, which accelerates mortar decay and can cause efflorescence — white salt staining on the brickwork. Properties in more exposed positions around Hill Head and Stubbington are particularly susceptible. We use mortar mixes appropriate to the exposure level and the age of the brickwork, ensuring the repair holds rather than causing further damage.
Do you carry out chimney repointing on post-war housing in Fareham as well as older properties?
Yes. Fareham has a significant amount of post-war and 1960s–1980s housing — particularly across the Titchfield Common and Crofton areas — many of which have chimney stacks with crumbling or incorrectly specified mortar from previous repair attempts. We work on all property ages and types and always match the mortar specification to the age and construction of the stack to avoid causing damage to the surrounding brickwork.
