Croydon's Victorian and Edwardian terraces are some of the borough's most characterful homes, but their original chimney stacks need specialist attention to stay weathertight. Years of freeze-thaw cycles, driving rain, and thermal movement take a steady toll on brick mortar, lead flashing, and lime-based flaunching. If you've noticed cracking around your chimney stack, damp patches on an internal chimney breast, or loose mortar falling into the fireplace, prompt chimney repairs in Croydon can prevent a minor defect from becoming an expensive structural problem.
Hills Roofing Ltd carries out all types of chimney repair work across Croydon and the surrounding areas. Connor Hill personally assesses every stack, identifies the root cause of the problem, and carries out lasting repairs, with no call centres and no subcontractors.
Most chimney deterioration is gradual and easy to miss from ground level. The most common issues we find on Croydon properties include:
Chimney repointing in Croydon is one of the most frequent jobs we carry out. We rake out failed mortar to an adequate depth and repoint using the correct mix. On Victorian and Edwardian stacks, a softer lime-based mortar is used to match the original construction and allow the brickwork to breathe, as cement-heavy mixes on older brickwork trap moisture and accelerate spalling, so the mortar specification is not a minor detail.
Lead flashing forms the critical weathertight seal between your chimney stack and the roof covering. Over time, step flashing, back gutter flashing, and soakers can lift, crack at joints, or lose their lead wedges, resulting in water ingress at the roofline. We repair or fully replace chimney flashing using high quality lead, properly dressed into the mortar joints and secured with lead wedges and flexible sealant.
Flaunching, the sloped mortar collar at the top of the stack, weathers and cracks, leaving chimney pots unsecured. We cut back and renew the flaunching bed, re-seat existing pots, or supply and fit replacement pots where the originals are damaged or missing. Where appropriate, we also fit rain cowls or anti-downdraught cowls to protect open flues from water ingress and wind.
Where a stack has deteriorated beyond repair, with severe spalling, bulging brickwork, or significant structural movement, a partial or full stack rebuild is the correct solution. We dismantle the affected section, source matching bricks where possible, and rebuild to a weathertight finish with new flaunching, pots, and lead flashing. All structural work carries a written guarantee.
Because chimneys are high up, problems often go unnoticed until they cause visible damp or structural movement inside. Warning signs to watch for include:

Common signs include crumbling or missing mortar joints between bricks, damp patches or tide marks on the chimney breast inside, white salt staining on the external stack face, or a tilted chimney pot. If you can spot gaps in the pointing from ground level, the chimney almost certainly needs professional attention.
Yes. Failed mortar pointing, cracked flaunching, and lifted lead flashing are among the most common causes of chimney-related damp. Water entering the stack can track down into the chimney breast, producing tide marks on ceilings and walls. Repairing the chimney itself is the only lasting fix; decorating over the damp will not solve the underlying problem.
For most chimney work, including repointing, flaunching repairs, and lead flashing replacement, scaffolding is required to work safely at height. Hills Roofing Ltd arranges scaffold where needed and includes it within the overall fixed quote. All our operatives are trained and insured for working at height.
Most chimney repointing and flaunching repairs are completed within one to two days, depending on the size of the stack. Lead flashing replacement is typically a half-day to full-day job. Stack rebuilds take longer depending on the extent of work involved. We will confirm the expected duration when we provide your written quote.
