Expert Chimney Repair Services Across the UK
Our certified engineers cover the full range of residential and commercial chimney repair services, working on all chimney types — brick, stone, rendered, Victorian, modern and heritage properties. Fully insured. Transparent pricing.
Chimney Repointing
Chimney repointing is one of the most common and essential chimney repairs. Over time, the mortar joints between your chimney bricks erode due to constant exposure to rain, frost and wind. Our repointing service removes all damaged mortar to the correct depth and applies a fresh, weatherproof mortar mix specifically suited to your chimney type — stopping water ingress at the source and restoring structural integrity for years to come. Average cost: £400 – £1,200.
Chimney Flashing Repair & Replacement
Chimney flashing is the lead or metal seal fixed between your chimney and the surrounding roof. When flashing deteriorates, water pours directly into your roof structure — causing rot, damp and internal water damage. Our team repairs and fully replaces chimney flashing using high-quality lead and approved sealants, ensuring a watertight, long-lasting bond. Average cost: £250 – £1,200.
Chimney Flue Lining & Relining
A cracked or deteriorated flue liner is a serious fire and carbon monoxide hazard. We supply and install flexible stainless steel flue liners, pumice liners and Thermocrete spray lining systems for all chimney types and fuel sources including wood, gas and solid fuel appliances. Average cost: £800 – £2,500.
Chimney Stack Repair & Rebuild
Your chimney stack bears the brunt of the British weather year-round. Our chimney engineers assess and repair everything from localised brick replacement to partial and full chimney stack rebuilds, using matching brick and stone materials wherever possible. All structural work is completed in line with current UK building regulations. Average cost: £500 – £10,000+.
Chimney Pot Repair & Replacement
Damaged, cracked or missing chimney pots are a direct route for rainwater into your chimney system. We supply and install a full range of standard and period-style chimney pots, cowls and bird guards to suit all property types. Average cost: £150 – £500 per pot including labour.
Chimney Flaunching Repair
Chimney flaunching is the sloped cement base that holds your chimney pots in place. Cracked or deteriorated flaunching allows water to pool and penetrate the stack top — one of the most common causes of chimney leaks. Our team hacks away failed flaunching and applies a fresh sand and cement mix, correctly sloped for rainwater runoff. Average cost: £150 – £400.
Chimney Leak Repair & Waterproofing
A leaking chimney is the number one cause of internal damp, ceiling staining and timber rot in UK homes. Our specialists locate the source of every chimney leak and apply the correct targeted repair to stop water entry permanently. We also offer chimney waterproofing treatments that seal porous brickwork without affecting breathability.
Chimney Inspection & CCTV Survey
Before any repair, our engineers carry out a full chimney inspection — from the pot at the top of the stack right down to the fireplace opening at the base. Where internal access is needed, we deploy specialist CCTV chimney cameras to inspect the full length of the flue. A detailed written inspection report is provided with every CCTV survey.

Brilliant service."

Common questions about our chimney repair service
Common signs include visible cracks in the brickwork or mortar, damp patches near the chimney breast, water stains on ceilings, loose or displaced chimney pots, smoke entering the room during use, and bits of mortar or brick debris falling from the stack. If you notice any of these, arrange a professional chimney inspection as soon as possible.
Costs vary based on the type of repair, chimney size and height, roof accessibility and your location. As a guide: chimney repointing £400–£1,200; flashing repair £250–£1,200; flaunching repair £150–£400; chimney pot replacement £150–£500 per pot; flue lining £800–£2,500; partial stack rebuild £600–£3,000; full stack rebuild £2,000–£10,000+; chimney waterproofing £200–£600; CCTV survey £100–£250. We provide a detailed, itemised quote before any work begins — no hidden costs, ever.
This depends on your specific policy and the cause of the damage. Sudden storm damage is often covered, while gradual deterioration through wear and tear typically is not. We recommend checking with your insurer and obtaining a detailed written survey report — which we can provide — before making any claim.
Minor repairs such as repointing, flaunching or pot replacement are typically completed within a single day. More substantial work such as flue relining or partial stack rebuilds may take two to three days. Larger structural rebuilds may take longer, particularly where scaffolding is required.
Not always. For lower roof pitches and accessible stacks, our engineers can work safely from ladders and roof ladders. For taller properties, steeper roofs or more substantial works, scaffolding is required. We will confirm whether scaffolding is needed during your free inspection.
In the majority of cases, yes. Even chimneys that appear severely damaged can often be repaired cost-effectively through targeted repointing, brick replacement, liner installation and flashing renewal. Full stack rebuilds are only ever recommended when the structure is genuinely unsafe beyond economic repair.
Any chimney in regular use should be professionally inspected at least once per year. Chimneys that have been out of use for an extended period should always be inspected before being put back into service, as blockages, liner deterioration and structural movement can occur even when a chimney is not being used.
Chimney repointing is the process of removing deteriorated mortar from the joints between chimney bricks and applying fresh mortar. It is one of the most effective ways to stop water entering a chimney stack and restore its structural integrity.
The most common causes are failed or lifting flashing, cracked or missing flaunching, deteriorated mortar joints and cracked chimney pots. A CCTV chimney survey is the most reliable way to identify the precise cause of any chimney leak.
No. A damaged chimney can allow carbon monoxide, smoke and hot gases to enter your home, and may present a fire risk. If you suspect your chimney is damaged, stop using your fireplace immediately and arrange a professional inspection before lighting any further fires.
