Many Aigburth homes in L17 are larger Victorian and Edwardian villas and semis with tall chimney stacks carrying several pots. Those stacks catch more weather, so pointing, flaunching and lead wear faster at the top. We repair, repoint, re-lead and rebuild them, starting with a proper inspection and a written quote with photos.
Why big houses have big chimney jobs
A villa built when every room had a fire might have three or four stacks, some with six or more pots. Each stack is a tall column of brick standing proud of the roof, wet on every side in a storm and slow to dry. Over time that wears the mortar joints, lets frost break up brick faces and loosens the flaunching around the pots. The lead where the stack meets the slates also moves and splits with age.
There is good news: most of these stacks are solidly built, and with sensible maintenance they last a very long time. What matters is catching problems while they are still a matter of repointing and lead rather than a rebuild.
What we inspect on an Aigburth stack
| Part | What we look for |
|---|---|
| Top courses and crown | Loose or missing bricks, open joints, frost damage |
| Flaunching | Cracks, gaps around pots, sections breaking away |
| Pots | Cracks, tilting, missing or rusted cowls |
| Lead flashing | Lifting, splits, cement fillets, blocked back gutter |
| Stack overall | Leaning, bulging, cracks running through the brickwork |
Repairs suited to larger stacks
Repointing and brick replacement
Where the joints have eroded, we rake them out and refill with a mortar that suits the brick. On older soft brick that usually means a mix no harder than the brick itself. Spalled bricks are cut out and replaced with the closest match we can find. Our chimney repointing page explains the process.
New lead flashing
Larger stacks have longer runs of lead, and a split or slipped section can let in a surprising amount of water. We replace flashing with lead of an appropriate thickness, properly dressed and chased into the joints, through our lead flashing repair work.
Rebuilding the top
If the top section is loose or out of line, taking it down to sound brickwork and rebuilding is often wiser than patching. A chimney rebuild can reuse sound original bricks and pots to keep the look of the house.
Fireplaces in use and disused flues
With so many flues, it is common for some to be in use and others sealed. Disused flues should be capped with a ventilated cap and vented at the bottom; active flues need a suitable cowl and a regular sweep by a qualified chimney sweep. We will ask which is which before fitting anything.

We also work in Mossley Hill and Allerton, which share many of the same house types. Learn more about our professional chimney repairs in Liverpool, or see how our Merseyside chimney service handles larger properties.

Frequently asked questions
My villa has several stacks. Do they all need doing at once?
Not necessarily. We inspect each one and tell you which are causing trouble now and which are in fair condition. Where scaffold is already up, it can make sense to deal with the worst issues on a neighbouring stack at the same time, but the choice is yours.
Why do tall stacks seem to need repointing more often?
A tall stack is exposed to wind and rain on all four faces, and the top courses stay wet longest. That steady wetting and freezing wears mortar and can damage brick faces, so the upper section often needs work before the lower part.
Can you use lime mortar on an older house?
On older soft brick, a mortar that is no harder than the brick is generally the right choice, and that can mean a lime-based mix. We look at the existing brick and pointing and recommend a suitable mortar rather than defaulting to hard cement.
Do you sweep chimneys before an open fire is used again?
No, we do not sweep chimneys. If you plan to use an open fire or stove, use a qualified chimney sweep. We can repair the stack, pots and flashing, and fit a suitable cowl once the flue is in use again.
