Chimneys are exposed to wind and rain on every side. Deteriorated mortar, cracked flaunching or failed flashings can let water into the roof and surrounding rooms. KC Roofing & Scaffolding Ltd assesses and repairs roofing-related chimney defects across East London, North London and Essex.

What we check

• Weathered or missing mortar joints and visible brickwork defects.
• Cracked flaunching around chimney pots.
• Lead flashings, soakers and chimney back gutters.
• Loose pots or other visibly unstable components.
• Adjacent tiles, slates and roof junctions.

The proposed repair follows the findings. A leak near a chimney may also involve the surrounding roof covering, so we investigate the junction rather than assuming repointing alone will solve it.

Repointing, flaunching and flashing repairs

Suitable repointing addresses defective mortar joints, while flaunching repairs deal with the weathering around the pots. Failed lead details may need local repair or replacement. Where more substantial brickwork deterioration is found, we explain the further assessment and scope needed before agreeing works.

Safe access planned with the repair

Chimney work requires an access arrangement suited to the height and location of the stack. Our in-house scaffolding can be coordinated with the roof work. We consider occupants, neighbouring property and areas beneath the chimney, and agree the access and protection in the quotation.

Structural concerns and working flues

Leaning stacks, extensive cracking or unstable masonry may require specialist structural advice. We identify these concerns rather than treating them as routine maintenance. Work on a working flue, appliance connection or ventilation may need an appropriate specialist; do not assume roofing repairs certify an appliance or flue.

How to request an assessment

1. Send the postcode and photographs taken safely from ground level.
2. Explain any leak, visible loose material or previous repairs.
3. Tell us whether the chimney is in use and describe access restrictions.
4. We arrange assessment and provide a written scope and quotation for suitable works.

Frequently asked questions

Can repointing stop a chimney leak?

It can help where failed joints are the cause, but flaunching, flashings and adjoining roofing also need checking.

Do all chimney repairs need scaffolding?

Access depends on the location, height and extent of work. We confirm the safe arrangement and its cost before starting.

What if parts of the chimney are loose?

Keep people away from the area beneath and contact us to discuss assessment. If there is immediate danger to people, use the appropriate emergency service. Do not climb onto the roof.
