Chimney Repair

Chimneys are essential architectural features that require specialist knowledge and care. At Sterling Roofing Services, we’ve been repairing, restoring, and maintaining chimneys across Scotland for over 20 years. Whether you have a leaking chimney, damaged brickwork, loose pots, or need a complete chimney rebuild, our experienced team provides quality chimney repair services that protect your property and preserve its character.

Chimney problems can’t be ignored. A damaged chimney can allow water into your property, causing interior damage, dampness, and structural issues. Loose chimney pots or unstable stacks pose safety risks. Failed flashing around chimneys is one of the most common sources of roof leaks. That’s why prompt, professional chimney repairs are essential for protecting your home.

We work on all types of chimneys – from Victorian brick stacks to stone chimneys on traditional cottages, and from working chimneys to disused stacks. Our comprehensive chimney services cover everything from minor repointing to major structural repairs and complete rebuilds. We combine traditional masonry skills with modern weatherproofing techniques to deliver chimney repairs that last for decades.

Our Chimney Repair Services

Chimney Repointing

Repointing is one of the most common chimney repairs we carry out. Over time, the mortar between bricks or stones deteriorates due to weather exposure, requiring renewal.

Signs You Need Chimney Repointing:

• Crumbling or missing mortar between bricks
• Gaps in the pointing visible from ground level
• Damp patches on interior walls near the chimney
• Mortar dust or debris falling from the chimney
• White salt deposits (efflorescence) on brickwork
• Previous pointing has completely failed

Our Repointing Process:

1. Inspection – We assess the extent of pointing failure
2. Scaffolding – Safe access to the chimney stack
3. Mortar removal – Carefully rake out old, failed mortar
4. Cleaning – Clean joints thoroughly for proper adhesion
5. Repointing – Apply appropriate mortar mix to match original
6. Finishing – Proper finish to match existing style
7. Curing time – Allow mortar to cure properly
8. Inspection – Final check of all work

Mortar Specification: We use the correct mortar mix for your chimney – typically lime-based mortar for older properties and appropriate cement/lime mixes for modern chimneys. Using the wrong mortar (too hard) can damage bricks, while too soft a mix won’t provide adequate weather protection.

Benefits of Professional Repointing:

• Prevents water penetration
• Extends chimney lifespan
• Maintains structural integrity
• Improves appearance
• Prevents further damage

Repointing should be carried out before damage becomes severe. Well-maintained pointing can last 30-50 years.

Chimney Stack Repairs

The chimney stack (the visible brick or stone structure above the roofline) can develop various structural issues requiring repair.

Common Chimney Stack Problems:

Damaged Brickwork:

• Frost-damaged bricks (spalling)
• Cracked bricks
• Loose bricks
• Deteriorated bricks

Structural Issues:

• Leaning chimney stacks
• Bulging sections
• Cracks in the stack
• Unstable chimney

Our Stack Repair Services:

• Brick replacement – Removing and replacing damaged bricks
• Crack repairs – Addressing cracks with proper techniques
• Partial rebuilds – Rebuilding damaged sections
• Stabilization – Securing unstable or leaning chimneys
• Structural reinforcement – Adding support where needed

When Repair vs. Rebuild:

• Repair if: Damage is localized, structure is fundamentally sound, most bricks are in good condition
• Rebuild if: Extensive damage, multiple structural issues, stack is dangerously unstable, most bricks are deteriorated

We’ll honestly assess your chimney and recommend the most cost-effective solution that ensures safety and longevity.

Complete Chimney Rebuilds

Sometimes a chimney has deteriorated beyond economical repair and requires a complete rebuild.

When Complete Rebuild is Needed:

• Severe structural deterioration
• Dangerous instability
• Extensive frost damage to most bricks
• Previous poor repairs have failed
• Chimney has been struck by lightning
• Historical chimney fires causing structural damage

Our Rebuild Process:

1. Dismantling – Careful removal of existing chimney stack
2. Structural assessment – Check base and surrounding roof structure
3. Rebuilding – Reconstruct chimney to original specifications or design
4. New lead work – Install all flashings and weatherproofing
5. Chimney pot installation – Fit appropriate chimney pots
6. Testing – Ensure structural integrity and proper flue function
7. Finishing – Complete all details and cleanup

Design Considerations:

• Matching original appearance for period properties
• Proper flue sizing if chimney is still in use
• Adequate weathering details (sloping tops, drip edges)
• Appropriate damp-proof course
• Proper integration with roof

For listed buildings or conservation areas, we work sympathetically to recreate the original chimney design while incorporating modern building standards where appropriate.

Chimney Flashing Repairs

Flashing creates weathertight seals between chimneys and roofs. Failed flashing is one of the most common causes of roof leaks around chimneys.

Types of Chimney Flashing:

Front and Back Aprons: Lead sheets covering the front and back of the chimney where it meets the roof

Stepped Flashing: Individual pieces of lead fitted between roof tiles and chimney brickwork on the sides

Back Gutter: Larger lead construction behind wide chimneys to channel water around the stack

Soakers: Individual lead pieces under tiles adjacent to chimneys

Common Flashing Problems:

• Split or cracked lead
• Failed mortar pointing (where flashing is tucked into brickwork)
• Inadequate flashing coverage
• Corroded or deteriorated lead
• Poor original installation
• Damage from chimney movement

Our Flashing Repair Service:

• Assessment – Identify all flashing issues
• Lead renewal – Replace failed lead with Code 4 or Code 5 lead
• Proper installation – Use correct techniques for lasting repairs
• Pointing renewal – Properly point flashing into brickwork
• Soaker installation – Fit lead soakers under adjacent tiles
• Testing – Ensure complete weatherproofing

Quality lead flashing, properly installed, should last 50+ years.

Chimney Pot Repairs and Replacement

Chimney pots serve both functional and aesthetic purposes. Damaged pots need prompt attention.

Common Chimney Pot Problems:

• Cracked pots
• Broken pots
• Loose pots (inadequate bedding)
• Missing pots
• Inadequate pot height
• Blocked pots

Our Chimney Pot Services:

• Pot replacement – Sourcing and installing matching pots
• Re-bedding loose pots – Properly securing pots in fresh mortar
• Cowl installation – Fitting chimney cowls and bird guards
• Period pot sourcing – Finding authentic pots for period properties
• Custom solutions – Installing appropriate pots for working chimneys

Chimney Pot Selection: For period properties, we source traditional clay pots that match the original design. For working chimneys, we ensure pots are appropriate for the fuel type and flue requirements.

Chimney Cowls and Guards: We can install various chimney accessories:

• Bird guards (prevent nesting)
• Rain cowls (keep rain out while allowing smoke escape)
• Anti-downdraft cowls (prevent wind blowing smoke back down)
• Capping cowls (for disused chimneys)

Chimney Weatherproofing and Capping

For disused chimneys or to improve weather protection, we provide professional weatherproofing services.

Chimney Capping: When a chimney is no longer in use, proper capping prevents water ingress while allowing ventilation:

Capping Options:

• Half-round capping – Traditional terracotta or concrete half-rounds
• Flat stone caps – Natural stone capping for traditional appearance
• Lead caps – Custom lead capping for superior weatherproofing
• Proprietary caps – Modern ventilated capping systems
• Mortar weathering – Sloped mortar top (for redundant chimneys only)

Important: Even disused chimneys need ventilation to prevent condensation and dampness. We never completely seal chimneys – proper capping includes ventilation.

Weather Slates: Traditional method using lead-lined slates to shed water from chimney tops while maintaining ventilation.

Chimney Removal

Sometimes removing a redundant chimney is the most appropriate solution.

When to Consider Chimney Removal:

• Chimney is beyond economical repair
• Chimney is structurally unsafe
• No longer needed and causing ongoing maintenance issues
• Building alterations make chimney redundant
• Cost of repair exceeds removal cost

Our Chimney Removal Service:

1. Planning check – Verify if removal requires planning permission
2. Structural assessment – Check what can safely be removed
3. Safe dismantling – Carefully take down chimney stack
4. Breast removal – Remove internal chimney breast if required
5. Structural support – Install proper support for remaining structure
6. Roof repair – Properly repair roof where chimney was removed
7. Interior finishing – Make good ceilings and walls
8. Waste removal – Responsible disposal of materials

What Can Be Removed:

• Stack above roof level (most common)
• Entire chimney including breast (requires structural support installation)
• Partial removal with capping

Building Regulations: Chimney removal, particularly when removing chimney breasts, requires building regulation approval to ensure proper structural support.

Chimney Maintenance

Regular chimney maintenance prevents expensive repairs and extends chimney lifespan.

Annual Inspection: We recommend annual chimney inspections to check:

• Pointing condition
• Brick or stone condition
• Chimney pot security
• Flashing integrity
• Signs of leaks
• Structural stability
• Any movement or cracks

Working Chimneys: If you use your chimney, additional maintenance is essential:

• Annual professional sweep
• Regular fire box cleaning
• Flue inspection
• More frequent structural checks
• Carbon monoxide detector maintenance

Disused Chimneys: Even unused chimneys need maintenance:

• Annual visual inspection
• Ensure ventilation is adequate
• Check for deterioration
• Monitor for leaks
• Keep gutters clear of debris from chimney

Maintenance Contracts: We offer annual maintenance contracts for homeowners who want:

• Scheduled inspections
• Early problem detection
• Priority repair service
• Peace of mind protection
• Discounted repair rates

Chimney Design and Construction

Understanding proper chimney construction helps explain why problems occur and how repairs should be done.

Traditional Chimney Construction

Stack Components:

• Foundation – Adequate support for chimney weight
• Breast – Interior portion containing flues
• Stack – Exterior portion above roofline
• Flue – Internal passage for smoke
• Pots – Terminals extending above stack
• Weathering – Top surface sloped to shed water
• DPC – Damp-proof course to prevent rising damp

Proper Design Features:

• Adequate flue sizing for fuel type
• Proper height above roof ridge
• Sloped top to shed water
• Drip edges on projections
• Quality mortar and brickwork
• Proper integration with roof
• Adequate ventilation

Modern Building Standards

Today’s chimney repairs must meet current standards:

Building Regulations:
