Professional Chimney Repairs You Can Rely On
Your chimney stack is one of the most exposed parts of your property. Sitting above the roofline and constantly subjected to wind, rain, frost, and temperature changes, chimney stacks deteriorate over time — and when they do, the problems they cause can extend well beyond the chimney itself. Cracked flaunching allows water to seep around the base of your chimney pots, eroding the mortar and loosening the pots until they become a genuine safety risk. Deteriorating pointing between the bricks lets moisture penetrate deep into the stack, leading to damp patches on internal walls, staining on ceilings, and in severe cases, structural instability. Failed lead flashings where the chimney meets the roof are one of the most common causes of persistent roof leaks across Hampshire, Surrey, and Berkshire. Thermoshield Ltd has been repairing chimneys for homeowners across Fleet, Camberley, Farnborough, Bracknell, Farnham, and the wider area for over 20 years, and we understand exactly what these stacks endure and how to fix them properly.
Whether you need a straightforward flaunching repair on a semi-detached house in Wokingham, a full chimney stack rebuild on a period property in Ascot, or a chimney removal on a modern home in Basingstoke, our skilled team delivers the same high standard on every job. We begin with a thorough inspection of the entire chimney — stack, pots, flaunching, pointing, lead work, and the surrounding roof area — to identify every issue, not just the obvious ones. We then provide a clear, written quotation with no hidden costs, and carry out the work using quality materials and proven techniques that ensure a long-lasting result. All chimney repair work is fully guaranteed, and our Checkatrade membership means you can verify our track record before we start. If you’re unsure whether your chimney needs attention, call us on 07505 262511 for a free inspection and honest advice.
Our Chimney Repair Services
We provide the full range of chimney repair, maintenance, and removal services for homeowners across Hampshire, Surrey, and Berkshire. Whatever the condition of your chimney, our experienced team has the skills and equipment to resolve the issue safely and effectively.
Repointing Chimney Brickwork
Over time, the mortar joints between chimney bricks erode due to constant exposure to wind, rain, and frost. This allows water to penetrate the stack, causing damp, staining, and eventual structural weakening. We carefully rake out the old, deteriorated mortar and repoint the joints using a durable, weather-resistant mix that restores the stack’s integrity and protects it for years to come. A common repair across older properties in Farnham, Ascot, Windsor, and Maidenhead.
Chimney Flaunching Repairs
Flaunching is the mortar bed that sits on top of the chimney stack, holding the chimney pots in place and directing rainwater away from the stack. When it cracks, crumbles, or separates from the pots, water can pool around the base of the pots and seep directly into the chimney. We remove the old flaunching and apply a new, properly shaped mortar bed that sheds water effectively and secures your pots firmly. One of our most frequently requested chimney repairs across Fleet, Camberley, Farnborough, and all surrounding areas.
Securing or Replacing Chimney Pots
Loose, cracked, or damaged chimney pots are both a leak risk and a safety hazard — a pot dislodged by high winds can cause serious damage or injury. We secure loose pots with fresh flaunching, replace cracked or broken pots with matching replacements, and fit new pots where required. If the chimney is no longer in use, we can cap the pots to prevent water ingress while maintaining ventilation to the flue.
Chimney Stack Lead Work Repairs
Lead flashings where your chimney meets the roof are one of the most common causes of roof leaks. Over time, lead can crack, lift, corrode, or separate from the brickwork, allowing water to penetrate the junction between the stack and the roof covering. We repair and replace chimney lead work including step flashings, back gutters, apron flashings, and soakers — ensuring a watertight seal that lasts. Serving all areas including Aldershot, Hook, Sandhurst, and Lightwater.
Installation of Chimney Cowls & Vents
Chimney cowls and vents serve a range of purposes — from preventing rain, birds, and debris entering the flue to improving draught performance and reducing downdraught problems. We supply and fit a range of cowls and ventilation caps to suit your chimney’s function, whether the flue is active, disused, or being capped off. Available across all of our Hampshire, Surrey, and Berkshire service areas.
Removing or Capping Off Chimneys
If your chimney is no longer in use — perhaps you’ve switched to central heating or the fireplace has been permanently closed off — removing or capping the stack can eliminate an ongoing source of maintenance and potential water ingress. We carry out partial removals (taking the stack down to roof level), full removals, and capping-off work, always ensuring the roof is properly sealed and weatherproofed afterwards. A popular service for homeowners in Bracknell, Wokingham, Crowthorne, and Windlesham.
Building New Chimney Stacks
Whether you’re installing a new wood-burning stove, reinstating a previously removed chimney, or building an extension that requires a new flue, we construct chimney stacks from scratch to meet current building regulations. Our new builds include proper lead work, flaunching, and pot installation — delivering a complete, watertight chimney that’s built to last.
Chimney Stack Refurbishment
For chimney stacks that have multiple issues — failed pointing, cracked flaunching, corroded lead work, and damaged pots — a full refurbishment is often the most cost-effective approach. We strip back the deteriorated elements, rebuild where necessary, repoint the brickwork, apply new flaunching, replace or resecure the pots, and install new lead flashings. The result is a chimney stack restored to full working condition with years of maintenance-free life ahead. Available across Basingstoke, Yateley, Bagshot, and all surrounding areas.
Chimney Damp & Water Ingress
If you’ve noticed damp patches, staining, or a musty smell around your chimney breast inside the house, the cause is almost certainly water finding its way into the stack from above. The source could be failed flaunching, deteriorated pointing, cracked lead work, a missing cowl, or a combination of these issues. We carry out a full chimney inspection to pinpoint exactly where the water is entering and carry out the repairs needed to stop it permanently. Don’t ignore chimney damp — the longer it’s left, the more extensive and expensive the damage becomes.

Frequently Asked Questions About Chimney Repairs
Below are the answers to the most common questions homeowners across Hampshire, Surrey, and Berkshire ask about chimney repairs. If your question isn’t covered here, give us a call on 07505 262511 — we’re always happy to help.
Common signs include damp patches or staining on the ceiling or walls near the chimney breast, crumbling mortar visible on the stack from ground level, loose or leaning chimney pots, a musty or damp smell in the room with the fireplace, and debris falling into the fireplace or grate. If you notice any of these, it’s worth getting a professional inspection before the problem gets worse.
Flaunching is the shaped mortar bed on top of your chimney stack that holds the pots in place and directs rainwater off the stack. It cracks over time due to constant exposure to freezing and thawing cycles, wind, and rain. Once cracked, water seeps in around the pots and into the stack, causing damp and further deterioration. Re-flaunching is a straightforward repair that prevents much more costly damage.
The cost depends on the type and extent of the repair needed. A simple re-flaunching or pot replacement will cost significantly less than a full stack refurbishment or chimney removal. We provide free, no-obligation quotes for all chimney work, so you’ll know exactly what to expect before any work begins. Call 07505 262511 to arrange a free inspection.
In most cases, yes. Safe access to the chimney stack is essential for both inspection and repair work. Scaffolding ensures our team can work safely and carry out a thorough, high-quality repair. We organise all scaffolding as part of the job and include the cost in your quotation — there are no hidden extras.
Not necessarily. If the chimney is in reasonable condition, capping it off with a ventilated cowl is often sufficient to prevent water ingress while maintaining airflow to the flue. However, if the stack is in poor condition and causing ongoing problems, a partial or full removal may be more cost-effective in the long term. We’ll inspect the chimney and advise on the best option for your situation.
Yes — this is one of the most common consequences of chimney damage. Water entering through cracked flaunching, failed pointing, or deteriorated lead flashings can travel down the chimney breast and cause damp patches, staining, peeling paint, and mould growth on internal walls and ceilings. Repairing the chimney from the outside stops the water at its source.
