Is It Time for a Chimney Survey?
A chimney takes more weathering than almost any other part of the roof — these are the signals worth acting on.
Crumbling or missing mortar
Mortar joints that are soft, cracked or falling away let water into the brickwork, accelerating damage with every frost.
Visible lean or bulging
Any noticeable tilt or bulge in the stack needs assessing promptly — chimneys are heavy, exposed structures.
Loose or missing bricks
Individual brick failure often signals the whole stack is due repointing or a partial rebuild before it gets worse.
Damp patches near the chimney breast
Staining inside the house near a chimney can come from the brickwork, the flashing, or both — worth a proper survey to tell which.
Four Services, Matched to What Your Chimney Needs
Not every chimney problem needs a full rebuild — your surveyor recommends the right level of work for the actual condition of your stack, not the most expensive option.
Repointing
Raking out failed mortar and repointing with a matching mix — the most common chimney job, and often all a structurally sound stack actually needs.
Partial Stack Rebuild
Taking down and rebuilding the damaged section of the stack — typically the top few courses, where weathering is most severe — while retaining sound brickwork below.
Full Stack Rebuild
Full chimney taken down and rebuilt to match the original, used where structural movement or widespread deterioration goes beyond a partial repair.
Pots & Cowls
Replacing damaged or missing chimney pots, fitting cowls to keep birds and rain out, or capping redundant flues that are no longer in use.
Chimney Repair on Barnet's Housing Stock
Barnet’s property types shape the most common chimney jobs here.
Finchley, Edgware & Mill Hill's Semis
Many of Barnet's semi-detached houses share a chimney stack across the party wall, meaning repointing work often needs coordinating with a neighbour.
Hendon & Golders Green's Mansion Blocks
Larger mansion blocks and detached houses here often have taller stacks with multiple pots, needing more careful access and repair.
Converted Properties
Properties converted into flats across the borough sometimes have redundant flues needing capping rather than full repair.
Finchley to Edgware
Emergency cover across the full borough, from Finchley and Hendon out to Golders Green, Mill Hill and Edgware.

What Barnet Homeowners Say
Finchley · Chimney Repointing
“Mortar had been crumbling for a couple of years. Surveyor confirmed repointing was genuinely all it needed, not the full rebuild a previous quote had pushed. Honest and thorough.”
“Top few courses of the stack were visibly loose after a windy winter. Rebuilt just the affected section rather than the whole thing, matched the brick nicely, scaffolding included as quoted.”
Edgware · Chimney Survey & Capping
“Old fireplace chimney hadn’t been used in years and had a family of pigeons living in it. Capped properly with a vented cover, no more nesting, no more debris in the flue.”

Chimney Repair in Barnet, Answered
It comes down to whether the brickwork itself is structurally sound. If the bricks are solid and it's just the mortar that's failed, repointing is usually all that's needed. If bricks are loose, cracked, or the stack shows signs of movement, a partial or full rebuild is the honest recommendation. Your free survey will tell you which.
Not indefinitely. A chimney is a heavy, exposed structure, and visible lean usually means the mortar bed or foundation has weakened. It's worth getting assessed promptly rather than waiting — we'll give you an honest read on urgency during the survey.
Both are common culprits and they need different fixes — porous brickwork or failed pointing lets water through the masonry itself, while failed lead flashing lets water in at the junction between the chimney and the roof. Our survey checks both, and if it turns out to be a flashing issue specifically, see our Leadwork & Flashing Repair page.
Yes. A redundant chimney should still be capped or fitted with a vented cowl to stop water ingress and prevent birds nesting in the flue, even if the fireplace below is no longer used.
Most like-for-like repairs don't need permission. If your property is listed or in a conservation area, changes to the chimney's appearance or materials may need consent — we'll flag this during your free survey if it applies to your property.
