What We Do: Complete Chimney Solutions
Your chimney is constantly exposed to wind-driven rain, frost and temperature changes. Over time, mortar joints can deteriorate, lead flashing can split or lift, flaunching can crack, and chimney pots or cowls can become loose. These defects can allow water to enter the roof and surrounding masonry.
Jade Roofing Experts provides chimney and leadwork repairs for homeowners, landlords, managing agents and businesses across London. From local flashing repairs and chimney repointing to rebuilding or carefully removing a damaged stack, we inspect the cause before recommending the appropriate work.
We use proven roofing materials and installation methods, including BBA-certified products where they form part of the specified repair system. Any applicable guarantee is based on the agreed work and confirmed in writing before the project begins.
What We Check During an Inspection
We examine the chimney and its connection to the surrounding roof so the visible symptom is not treated without checking the likely cause.
Repair before rebuild: If a durable flashing repair, local repointing or flaunching repair is sufficient, we will explain that option rather than automatically recommending a complete chimney rebuild.
Warning Signs: Does Your Chimney Need Repair?
Chimney defects are often noticed indoors before the damage is visible from ground level. Arrange a professional inspection if you notice any of the following warning signs.
Damp Patches and Water Stains
Brown marks, peeling paint or damp around the ceiling and chimney breast can indicate that water is entering around the chimney or surrounding roof junction.
Crumbling Mortar and Loose Brickwork
Sand, mortar fragments or pieces of brick appearing in the gutter may mean that the chimney joints are deteriorating and need professional repointing.
Cracked or Missing Lead Flashing
Loose, split or missing lead around the base of the chimney can allow rainwater beneath the roof covering and into the property.
Leaning or Unstable Chimney Stack
A chimney that looks tilted, cracked or unstable may have structural movement or weakened masonry and should be assessed as soon as possible.
Draughts, Debris or Damaged Pots
Unexpected draughts, masonry debris or pieces of a chimney pot entering the fireplace can indicate damage at the top of the stack.
Important safety notice: If the chimney is visibly leaning or bricks, mortar or chimney pots appear loose, keep people away from the area below and arrange an urgent professional assessment. Do not attempt to inspect the roof yourself.
Not Sure What Is Causing the Leak?
Water can travel across roof coverings, brickwork and internal timbers before appearing indoors. Jade Roofing Experts can inspect the lead flashing, mortar joints, flaunching and surrounding roof junctions to identify the likely source.
Our Chimney and Leadwork Services
We handle chimney repairs of all sizes, from isolated lead flashing problems to extensive masonry restoration. Our recommendations are based on the condition of the flashing, mortar, bricks, flaunching and adjoining roof, so you only receive a quote for the work your chimney needs.
Lead Flashing Repair and Replacement
Lead flashing seals the vulnerable junction between the chimney and roof. When it becomes cracked, loose or poorly fitted, rainwater can enter beneath the roof covering.
- Inspection of chimney and roof junctions
- Repair of isolated splits or loose sections
- Replacement of severely failed lead flashing
- Careful detailing around the chimney base
Chimney Repointing
Wind and rain gradually erode the mortar between chimney bricks. We remove loose, deteriorated mortar and renew the joints to improve stability and weather resistance.
- Removal of loose and crumbling mortar
- Renewal of damaged masonry joints
- Assessment of cracked or unstable bricks
- Clean finish suited to the existing masonry
Chimney Rebuilding and Removal
When a stack is too extensively damaged for local repair, we can carefully dismantle and rebuild the affected section. Disused stacks may also be removed where appropriate.
- Assessment of the stack’s visible condition
- Rebuilding damaged sections from roof level
- Removal of disused chimney stacks where suitable
- Weatherproofing of the affected roof area
Pots, Cowls and Flaunching
Cracked flaunching can allow water to collect around the chimney pots. Loose pots and unsuitable or damaged cowls can also expose the chimney to rain, debris and birds.
- Repair or renewal of cracked flaunching
- Resetting or replacing damaged chimney pots
- Installation of a suitable chimney cowl
- Inspection of the top of the chimney stack
What We Check During Your Chimney Inspection
Which Chimney Repair Does Your Property Need?
We will inspect the affected area, explain the likely cause of the problem and provide a written quotation for the recommended work. If a local repair is sufficient, we will not automatically recommend extensive rebuilding.

Clear and Honest Pricing
Every chimney is different, so an accurate repair price depends on the condition of the structure and the work required. We inspect the problem first and then provide a clear, property-specific quotation.
What Affects the Cost of Chimney Repair?
We do not use a generic price list that ignores the actual condition of your chimney. Your quotation is based on the following practical factors.
The Extent of the Damage
An isolated flashing repair will usually involve less work than widespread mortar failure, unstable bricks or rebuilding part of a chimney stack.
Materials and Repair Method
The cost depends on whether the work requires lead flashing, new mortar, replacement bricks, flaunching, chimney pots, cowls or structural rebuilding.
Height and Access Requirements
Roof height, restricted access, scaffolding, specialist equipment and any required local permits can affect the final project cost.
No unexpected additional work: If concealed damage is discovered after work begins, we will explain the issue and obtain your approval before completing work outside the original agreed scope.

Do you provide a guarantee on chimney repairs?
Written guarantees are available on qualifying work. Depending on the repair type and agreed specification, qualifying chimney and leadwork projects may include a workmanship guarantee of up to 25 years. The exact coverage, duration and exclusions will be confirmed in your written quotation.
Is the initial chimney inspection free?
Yes, we offer a free initial inspection and quotation for standard enquiries within our service area. If specialist access equipment, scaffolding or a more extensive diagnostic survey is required, we will explain this before arranging any chargeable work.
Do you organise scaffolding and access permits?
Yes, where scaffolding or specialist access is required, we can help coordinate the necessary arrangements. We will explain known scaffolding, access and permit requirements and include the relevant costs in your quotation wherever possible.
Can you attend today for an emergency chimney leak?
We prioritise urgent chimney and lead-flashing leaks whenever possible. Same-day attendance depends on your location, current team availability, weather conditions and whether the roof can be accessed safely. Call 07955 558880 and describe what is happening so we can advise you on the next appropriate step.
Do you use approved chimney and leadwork materials?
We select materials and systems appropriate for the property and the agreed repair. Where a BBA-approved product or system is suitable, the approval applies to that specific product and its intended installation. Your quotation will identify the main materials proposed for the work.
How do I know if my chimney needs repair?
Common warning signs include cracked or missing mortar, loose bricks, damaged lead flashing, water stains near the chimney breast, internal damp patches, broken chimney pots, falling debris or a stack that appears to be leaning. A professional inspection can help identify the cause and severity of the problem.
Can you repair leaking chimney flashing?
Yes. We inspect the lead flashing, chimney base, mortar joints and surrounding roof covering to identify the likely entry point. Depending on its condition, failed flashing may be repaired locally or replaced to restore durable weather protection around the chimney junction.
Every chimney is different. The final recommendation, cost and guarantee depend on the inspection findings and agreed repair specification.
