Chimney repairs in Southsea — repointing, lead flashing, stack rebuilds and pot replacement. Southsea's shared party wall chimney stacks on terraced rows are the most complex chimney repair environment in Portsmouth.
Lead flashing failure, ridge mortar deterioration and pot haunching failure are the most common chimney calls from Southsea. We assess the full stack on every job not just the reported failure point.
Repointing is appropriate where brick faces are intact and only mortar joints have failed. Rebuilding is required where bricks have spalled, the stack has leaned or structural movement is present.
Correct lead code for the exposure position is specified on every Southsea chimney job. Heavier code on harbour-facing and seafront elevations. The additional cost is modest against the extended replacement interval.
Southsea's shared party wall chimney stacks on terraced rows are the most complex chimney repair environment in Portsmouth. Salt corrosion, shared ownership and conservation area constraints all apply simultaneously. The most common calls we receive for chimney work in Southsea are lead flashing failure, mortar joint deterioration and pot haunching failure. We assess the full stack on every chimney job — treating only the visible failure while leaving secondary damage unaddressed is a false economy.
Repointing is appropriate where the brick faces are intact and only the mortar joints have failed. Rebuilding is required where bricks have spalled, the stack has leaned or water has penetrated the core. We assess this honestly on survey — a stack that needs rebuilding will not be quoted as a repointing job.
Code 6 on seafront-facing Southsea elevations. Code 5 minimum elsewhere in Southsea. We do not specify code 4 anywhere in Southsea — the Channel exposure makes it an inadequate specification. We specify the correct lead code for the exposure position — heavier code on coastal and harbour-facing elevations. The additional cost of heavier lead is modest against the longer replacement interval it provides.

"Full re-roof on our Albert Road Victorian — direct seafront exposure meant the original fixings had gone completely. Marine-grade stainless throughout, coastal-grade lead on the chimney. Excellent work."
"Shared chimney stack on our Southsea terrace — coordinated with next door and did the full stack in one visit. First time it's been properly done."
"Flat roof on our loft conversion — south-facing, full Channel exposure. Portsmouth Roofing recommended GRP over felt without hesitation. Right call."

Yes where appropriate — Victorian and Edwardian chimneys in Southsea require lime mortar, not OPC cement. Hard cement on soft brick causes spalling. We specify the correct mortar for the chimney age and construction.
Yes — shared party wall stacks are one of the most common chimney jobs in Southsea's terraced streets. We coordinate with both households and price the full stack, not just one side.
Yes — from £350. Capping an unused stack properly prevents water ingress and is significantly cheaper than repairing the damp damage that results from an open stack.
