Chimney Repairs & Repointing in West Sussex
Expert chimney repairs, repointing, lead flashing and chimney pot replacement across Pulborough and West Sussex. Free inspections and no-obligation estimates on all work.
Chimneys sit at the most exposed point of your roof, taking the full force of the British weather year after year. Crumbling mortar, failed lead flashing, cracked pots and deteriorating brickwork are all common problems — and all can lead to serious damp and structural damage if left unattended. AJW Roofing Ltd provide expert chimney repairs and repointing across Pulborough and West Sussex.
Chimney Repair Services We Provide
At AJW Roofing we handle the full range of chimney repair work — from routine repointing and flashing replacement through to full chimney rebuilds. We also inspect every chimney we can access whenever we are carrying out other roofing work, so problems are caught early before they become costly.
Chimney Repointing
Raking out deteriorated mortar and replacing it with fresh mortar — restoring the waterproofing and structural integrity of the chimney stack.
Lead Flashing
Repair and full replacement of chimney lead flashing — the most common cause of chimney-related roof leaks in UK homes.
Flaunching Repair
Replacement of cracked or failed chimney flaunching to secure chimney pots and reseal the top of the stack.
Chimney Pot Replacement
Standard and decorative chimney pot replacement, including period-style pots to match the character of older Sussex properties.
Brickwork Repairs
Replacement of individual damaged bricks and sections of chimney brickwork that have cracked or deteriorated beyond repointing.
Chimney Rebuilds
Partial and full chimney stack rebuilds where deterioration is too advanced for repairs alone — carried out safely and properly.
Chimney Repointing — What's Involved
Repointing is the most common chimney repair we carry out. Over time, the mortar between the bricks of a chimney stack erodes due to wind, rain, frost and the constant cycle of heating and cooling that chimneys go through. When the mortar fails, water can penetrate the brickwork, causing damp inside the property and accelerating the deterioration of the stack.
A proper repointing job involves carefully raking out the old, failed mortar to an adequate depth before packing new mortar into the joints. Simply applying new mortar on top of old without removing the deteriorated material is a common shortcut that leads to early failure — AJW Roofing always do the job properly. The correct mortar mix is also important; too strong a mix can actually damage older brickwork, so we always match the mortar to the age and type of the chimney.
Chimney Lead Flashing
The lead flashing where the chimney meets the roof tiles is one of the most vulnerable points on any roof. It is the seal that prevents water from running down between the chimney stack and the surrounding tiles and into the building. Well-installed lead flashing can last for many decades, but it does fail over time — particularly where the mortar holding the lead into the brick joints has cracked and allowed the flashing to lift or pull away.
A failed chimney flashing is one of the most common causes of roof leaks in older properties. At AJW Roofing we replace and repair chimney lead flashing to a high standard, ensuring a weathertight seal that will last. We inspect the surrounding tiles and brickwork at the same time to make sure there are no other contributing factors to the leak.
Chimney Pots & Flaunching
The flaunching is the cement mortar that holds the chimney pots in place at the top of the stack. It takes a considerable battering from the elements and will eventually crack and crumble, leaving pots loose and potentially unstable. A loose chimney pot is a genuine safety hazard and should be attended to promptly.
AJW Roofing replace cracked and failed flaunching and can supply and fit chimney pots of all styles — from standard terracotta to decorative and period-appropriate designs that suit the older properties found throughout Pulborough, Petworth and the wider West Sussex area.

The most common signs include crumbling, cracked or missing mortar between the bricks; white chalky staining on the brickwork (known as efflorescence), which indicates moisture is getting in; damp patches on interior walls or ceilings near the chimney breast; water appearing in the fireplace after rain; and loose or leaning brickwork at the top of the stack. If you notice any of these, it is worth having the chimney inspected before the problem worsens.
Chimney repointing is the process of removing deteriorated mortar from between the bricks and replacing it with fresh mortar. Chimneys sit above the roofline and are exposed to the full force of wind, rain, frost and temperature changes year round. Over time, the mortar erodes and cracks, allowing water to penetrate the brickwork. If left unattended this can cause damp, structural damage and eventually a dangerous, unstable chimney stack. Repointing restores the waterproofing and structural integrity of the chimney and typically needs to be done every 30 to 50 years.
The cost of chimney repointing in West Sussex depends on the size and height of the chimney, the extent of the deterioration and whether scaffolding is required. As a general guide, a standard chimney repointing job typically costs between £400 and £900 including labour and materials. More extensive work or larger stacks will cost more. AJW Roofing always provides a clear, itemised free estimate before any work begins — no hidden costs.
Chimney flashing is the lead seal where the chimney meets the roof tiles. It prevents water from running down between the chimney and the roof and into the building. Lead flashing is durable and can last for many decades when correctly installed, but it can fail over time due to thermal movement, poor original installation, or mortar joints cracking and allowing the lead to lift. Failed flashing is one of the most common causes of chimney-related leaks. AJW Roofing replace and repair chimney flashing as part of our standard chimney repair service.
Replacing lead flashing around a chimney in West Sussex typically costs between £350 and £800, depending on the size of the chimney, the amount of lead required and whether scaffolding is needed. AJW Roofing will assess the condition of your existing flashing and advise on whether a repair or full replacement is the right approach before any work begins.
Flaunching is the cement mortar that sits at the base of the chimney pots, holding them in place and sealing the top of the chimney stack. Over time it cracks and crumbles due to frost, weather and age. When flaunching fails, chimney pots can become loose or unstable — which is a safety risk — and water can get into the chimney stack. AJW Roofing replace cracked or failed flaunching as part of our chimney repair service, typically costing between £150 and £400 depending on the extent of the work.
Yes. Chimney pots can crack in frost, become damaged in storms, or simply deteriorate with age. AJW Roofing replace chimney pots of all styles, including standard terracotta pots and decorative or period-style pots to match the character of older Sussex properties. Chimney pot replacement typically costs between £100 and £250 per pot plus access costs. We will always inspect the flaunching at the same time and replace it if needed.
Contact AJW Roofing as soon as possible. Chimney leaks can have several causes — failed flashing, cracked flaunching, deteriorated repointing or damaged brickwork — and correctly identifying the source is essential before any repair work begins. We inspect every chimney thoroughly before recommending any work, so you can be confident the repair addresses the real cause of the problem rather than just the symptoms.
Yes. Whenever we are on a roof carrying out any roofing work, we always take the opportunity to inspect the chimney stacks at the same time. This allows us to spot any developing problems early — before a small crack in the mortar becomes a serious leak or a loose chimney pot becomes a safety hazard. If we spot anything that needs attention, we will let you know and discuss the options with you before any additional work is carried out.
Yes. Where a chimney stack has deteriorated beyond the point where repointing or partial repairs are sufficient, a full or partial rebuild may be required. This involves taking down the damaged brickwork and rebuilding it in sound materials. AJW Roofing carry out partial and full chimney rebuilds as well as the full range of chimney repairs. A partial chimney rebuild typically costs between £1,000 and £3,000 depending on the extent of the work, whilst a full rebuild costs from £2,500 upwards. We will always give you an honest assessment of what is needed.
