Chimney repair in St Helens covers a wide spread of homes across WA9, WA10 and WA11, from terraced streets to inter-war semis with a shared central stack. Most problems are leaks through flashing, flaunching or worn brickwork, or damp from flues that have been sealed without ventilation. We trace the cause first, then give you a written quote with photos.
Finding the real cause of a damp chimney
The most expensive chimney repair is one that does not fix the problem. Damp on a chimney breast can have several causes, and some homes have more than one at once. That is why we ask questions before we visit and look at the outside and inside of the chimney together.
Clues from the pattern of damp
- Appears after heavy rain, near the ceiling: often lead flashing, a cracked fillet or a blocked back gutter.
- High on the breast, under the pots: often cracked flaunching or an uncapped flue.
- Spread across the breast, worse in winter: often condensation in a sealed flue, or porous brickwork.
- Patchy, salty, never fully dries: possibly salts in old plaster drawing moisture from the air.
These are only clues. The inspection confirms what is really happening. If you want to read more first, our chimney problems guide covers each cause.
The house types we see
St Helens has a lot of inter-war semis, where a single ridge stack is shared with the attached house, and plenty of older terraced streets with shared party-wall stacks. Both types put a premium on talking to your neighbour, since a leak in shared masonry may need work on both sides to stop. There are also older detached and town houses with taller chimneys and more pots, where access planning matters more.
Repairs, from small to substantial
- Caps and vents for disused flues, letting them breathe and keeping rain out.
- Flaunching and pots renewed and rebedded where the top has cracked.
- Lead flashing replaced where it has split or been patched with cement, through our flashing repairs.
- Repointing and brick replacement where joints and faces have worn; see chimney repointing.
- Rebuilds where the stack is loose, leaning or cracked through, explained on our rebuild page.
If a stack is visibly leaning or dropping masonry, keep everyone clear of the area below and call us. Do not go onto the roof.
Why we photograph everything
Most people never see the top of their own chimney. Photos taken during the inspection let you see the cracked flaunching, the gap behind the lead or the open pot for yourself, and they make the written quote easy to follow. You can share them with a neighbour on a shared stack, a landlord or a family member helping you decide. After the work, a second set shows exactly what was done, which is useful to keep with the house paperwork for the future.
From first call to finished stack
We call you back, ask what you can see, and arrange an inspection from the ground, a ladder, a drone or the roof as appropriate. You get a written quote that explains the cause and the options, with photos. Access is arranged safely before work begins, and you see photos of the finished repair.

Frequently asked questions
How do I describe my chimney problem over the phone?
Tell us which room the damp is in, whether it is near the ceiling or lower down, when it appears (after rain, in winter, all the time), whether the fireplace is open or blocked, and whether the stack is shared. A photo of the stack from the street helps a lot.
Why do you ask whether the damp is worse in winter?
Damp that peaks in cold months but not necessarily after rain can point to condensation in a sealed flue rather than a roof leak. Damp that follows rainstorms points more towards flashing, flaunching or pointing. It helps us plan the inspection.
Do you cover the whole of St Helens?
We work across the St Helens area, including WA9, WA10 and WA11. Give us the address when you call and we will confirm.
Can you inspect a chimney with a drone?
Where it is suitable and safe, yes. A drone gives clear photos of the top of a stack without anyone climbing onto the roof. Sometimes ground or ladder inspection is enough, and sometimes roof access is needed to see hidden details.
