Chimney repairs in Fareham — repointing, lead flashing, stack rebuilds and pot replacement. Fareham's 1930s semis carry chimney stacks that are now approaching 90 years — original lime mortar joints have generally failed and repointing with the correct breathable mix is now overdue on most.
Lead flashing failure, ridge mortar deterioration and pot haunching failure are the most common chimney calls from Fareham. 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 Fareham chimney job. Heavier code on harbour-facing and seafront elevations. The additional cost is modest against the extended replacement interval.
Fareham's 1930s semis carry chimney stacks that are now approaching 90 years — original lime mortar joints have generally failed and repointing with the correct breathable mix is now overdue on most. The most common calls we receive for chimney work in Fareham 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.
For harbour-facing elevations in Fareham we specify code 5 minimum. For sheltered rear positions code 4 is acceptable. 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 Catisfield semi — nail sickness across both rear slopes. Portsmouth Roofing surveyed the batten structure first, found deck issues and included them in the price. No surprises."
"Ridge repointing on our 1930s semi near Fareham town centre. The harbour humidity had rotted the mortar faster than expected. Job done properly with the right mix for the exposure."
"Flat roof on our 1960s garage — original felt well past life. GRP fitted in a day. Dry ever since."

Yes where appropriate — Victorian and Edwardian chimneys in Fareham 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 Fareham'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.
