Chimney repairs in Chesham and across Buckinghamshire
Chimneys take the brunt of the weather. They’re exposed on all sides, they move slightly with temperature changes, and over time the mortar, flashing and brickwork can start to give up. Often the first sign isn’t the chimney itself — it’s a damp patch on a bedroom wall, a stain on the chimney breast, or water finding its way in during wind-driven rain. Left long enough, small chimney issues can lead to loose brickwork, internal damp, and damage to the roof around the stack.
At Southeast Roofing & Building, we carry out chimney repairs in Chesham and throughout Buckinghamshire. We’ve got 10 years’ experience, we’re fully insured, all work is guaranteed, and we’re proud of the reviews we’ve built up on Checkatrade, TrustATrader and Google. If your chimney needs repointing, rebuilding in places, or the flashing has failed, we’ll put it right properly and explain what we’re doing as we go.
Our chimney repair service
in Chesham
Chimneys are one of the most common sources of roof leaks, especially on older properties. Problems usually come down to three areas: the mortar joints, the lead flashing, or the chimney pot and top section. We inspect the full stack and the surrounding roof area, then carry out repairs that stop water ingress and keep everything safe and stable.
What chimney repairs typically include
Depending on the condition of the stack, our work can include
Chimney repointing where mortar has cracked, washed out or become brittle
Re-bedding or replacing loose chimney pots and repairing the pot haunching
Brickwork repairs or partial rebuilds if sections are damaged or unstable
Chimney flashing repair where lead has lifted, split, or failed at the joints
Replacing or repairing soakers, back gutters and apron flashing around the base
Checking and securing leadwork into the brickwork (where chase lines have opened up)
New gutter installation for extensions, garages and new roofline set-ups
Water testing and inspection where leaks are hard to trace
If we find the leak is actually coming from nearby roof areas — for example, a valley or ridge issue close to the stack — we’ll tell you straight away. The goal is to fix the real cause, not just “do something” to the chimney and hope for the best.
How we deliver the work
We’ll assess the chimney safely, explain what’s failing and why, then carry out the repair using materials suited to the roof and the property. Chimney work needs a careful approach because it’s often tied into the roof covering and the internal structure. We take our time with the details — especially flashing, pointing depth, and weatherproofing — because those are the bits that prevent repeat damp problems.

Frequently Asked Question
How do I know if my chimney needs repointing?
Look for cracked or missing mortar, loose bricks, and damp patches appearing on the chimney breast inside. If the mortar is failing, water can get in and frost can make it worse over time.
Can chimney flashing cause roof leaks?
Yes — failed flashing is a very common cause. Chimney flashing repair can often solve a leak without needing wider roofing work, as long as it’s diagnosed properly.
Do you repair chimneys after storm damage?
We do. High winds can loosen pots, lift flashing, and open up joints. If something looks unsafe, call us and we’ll advise and arrange a visit.
Will you need to rebuild the whole chimney?
Not always. Many issues are resolved with targeted repairs like repointing or partial rebuilds, plus proper flashing. We’ll only recommend what’s needed.
Is your chimney repair work guaranteed?
Yes — all work is guaranteed and we’re fully insured.
