Chimney failures cause the most complex water ingress problems on period properties. Repointing, lead flashing replacement and pot work carried out in the correct materials for the property's age and construction.
Chimney repair on period properties requires the correct mortar specification and lead work standard. Portland cement on Victorian brickwork causes spalling. A single-piece lead apron instead of soakers and stepped flashings fails within a decade. We carry out chimney repairs to the correct specification for the property's age and construction throughout.

Correct Mortar Specification
Victorian and Edwardian chimneys require lime mortar for all repointing. Portland cement causes brick spalling through differential movement and moisture trapping. We mix to the correct NHL lime specification for each property — a decision based on brick type, exposure position and age of the structure. Soft brick, hard mortar: the combination causes the brick to fail first.
Lead Flashing Replacement
The correct installation uses individual soakers at each tile course with a separate stepped cover flashing over them, secured into raked mortar joints. This two-component system allows the flashing to move with the chimney and roof independently. A single-piece apron welded to the tile surface has no provision for movement and will lift within a decade. We replace to Lead Sheet Association standards throughout.
When to Rebuild
Most chimney problems — including those causing damp for years — are repairable without a rebuild. Rebuilding is needed when the stack has structural movement, when spalling has compromised masonry integrity, or when mortar failure is comprehensive to the point of instability. We assess this at survey and will tell you clearly which category applies.

Donnington sits south of chichester between the a27 and chichester harbour, combining post-war housing age with harbour-adjacent salt air acceleration. For roofing work in Donnington, this means Galvanised nail fixings corrode earlier here than on equivalent inland properties — the harbour proximity shortens the nail sickness timeline by 5 to 8 years. Residential streets between the a27 and the harbour edge. We factor all of this into our survey, specification and material choice on every Donnington job.
Donnington properties are assessed with the harbour proximity factor built into our specification from the start. Stainless fixings on guttering brackets, patination oil on lead work and enhanced durability materials on re-roofing are part of the standard Donnington specification — not extras or upgrades that need to be requested.

Chimney repair is one of the services where local knowledge of housing stock makes the most difference. The mortar specification for a Victorian Chichester terrace chimney is not the same as for a post-war property, and applying the wrong mortar causes damage that takes years to manifest and decades to properly reverse. We have been repointing Chichester chimneys in the correct lime mortar specification for over 20 years. The knowledge of what each era requires is built into our approach, not an extra to be requested.

How to Tell You Need Chimney Repairs
Chimney problems in Chichester — damp on the breast, staining, loose pots — almost always trace to failed flashing, cracked flaunching or open pointing letting water into the stack.
Damp or staining on the chimney breast inside
Loose or leaning chimney pots
Crumbling mortar visible in the stack joints
White staining (efflorescence) on the brickwork
A leak that appears near the chimney after rain
When it is not the answer: If the underlying covering is sound and the problem is localised, a targeted repair is the honest answer rather than a larger job. Read the full guide.

Chimney Inspection Process in Donnington Chichester
A chimney inspection covers every element that can fail: the flaunching (the mortar bed the pot sits in), the pot condition, the pointing in the main stack body, the lead soakers between each tile course and the stack, the stepped cover flashings on the stack face, the back gutter behind the stack, and the chimney breast internally for evidence of water ingress. In Donnington Chichester, where harbour-adjacent post-war residential with salt air acceleration, the failure patterns we typically find depend on the property age — Victorian and Edwardian chimneys present primarily with lead failure and lime mortar deterioration; post-war properties present with failed sand-cement flaunching and inadequate original flashing specification.
Repair vs Rebuild: How We Assess
Most chimney problems are repairable without a rebuild. Repointing, lead replacement and flaunching renewal cover the vast majority of cases we survey. A rebuild becomes necessary when the stack has structural movement — visible lean or displacement — when spalling has progressed to the point where individual bricks are structurally compromised, or when mortar failure is so comprehensive that the stack is genuinely unstable. We photograph everything at the survey and give you a clear, evidenced view of which category your chimney falls into. We do not recommend rebuilds when repointing is the appropriate response.
