A cracked chimney rarely fixes itself. Small cracks can let rain in, leading to damp walls, leaks, and bigger repair costs. Approved Roofing London Ltd provides chimney repair London services, from minor repointing to full stack rebuilds across Ealing and West London. Every chimney is different, so we start with a proper on-site inspection to find the real problem before recommending the right fix.

Catch the small stuff early and it stays small. Ignore it, and it turns into a proper job. If you're in one of Ealing's older properties, honestly, a quick yearly look is just sensible — those chimneys have been up there a long time.
A chimney tends to give you a bit of warning before things go really wrong. Keep an eye out for:
Get onto these early and it stays a small job. Leave it, and winter frost gets into those cracks, freezes, expands, and starts pushing bricks apart — at which point you're looking at a much bigger bill than you would've paid for the early fix.
What a job involves really depends on the age of the house and how long the problem's been sitting there. Broadly, we cover:
Before anything starts, we have a proper look at the specific chimney in front of us — no assuming, no generic fix applied blind.
This is the classic chimney problem — mortar weakens, water gets into the cracks, freezes, and pushes the bricks apart bit by bit. We take out the damaged mortar and replace it with a properly matched mix, which stops the moisture getting in and keeps the whole stack solid. Most repointing jobs, honestly, are done in a day.
Sometimes it's gone past a small fix — brick replacement or a full rebuild is genuinely what's needed. Cracked or missing pots are worth sorting quickly too, since they're basically an open invitation for rain (and birds) to get down the flue. We'll often fit a cowl at the same time, which helps with downdraughts and keeps debris out.
Flashing is what seals the join between chimney and roof, and when it cracks or works loose, it's a really common source of leaks — one that a lot of people mistake for a roof problem when it's actually the chimney all along. Worth catching early, since it's protecting the roof timbers in your loft directly underneath.
People go this route for a couple of reasons — the fireplace hasn't been used in years and they want the space back, or the stack's too far gone to realistically repair. This is a proper structural job, needing steel supports done correctly, so it's not one to hand to anyone who isn't genuinely certified and up to speed on building regulations. If the stack's removal means the surrounding roof covering needs attention too, that's the kind of work that can tie into a full new roof installation London job.
Chimneys don't always pick a convenient time to fail. A storm rolls through overnight and loosens some bricks, or a stack starts leaning and you notice it the next morning. When that happens, we get out to secure the property first — stop things getting worse — then plan out the proper fix once it's safe to do so. If the same storm's also lifted tiles or opened up a leak elsewhere on the roof, our emergency roof repair London team can deal with both at once.
We get asked a lot whether a small crack can just be patched up at home. Here's roughly how that plays out:
| Factor | Fix It Yourself | Call a Roofer |
|---|---|---|
| Safety | Risky work at height | Trained, insured team |
| Materials | Often the wrong mix | Matched to the brickwork |
| Guarantee | None | Written guarantee |
| Long-term cost | Repeat repairs likely | One lasting fix |
| Time | Trial and error | Diagnosed and fixed fast |
A chimney's up high, next to a working flue — it's genuinely not the place for a weekend ladder job and a bit of guesswork. Get the mortar mix wrong and it can crack again within a year, at which point you've paid twice for what a proper job would've sorted the first time.
