Eastleigh's Victorian-era town centre properties and the older pre-war stock in Bishopstoke carry chimney stacks that are approaching or past century-mark age. The Itchen Valley moisture levels accelerate lead fatigue at chimney abutments and mortar carbonation on exposed stacks — Eastleigh chimneys require more frequent maintenance than equivalent stacks on drier high-ground locations. The widespread 1960s–70s post-war housing on Boyatt Wood and Fleming Park also generates chimney work: redundant stacks on properties where gas replaced coal in the 1960s–80s often have deteriorating pots and failed pointing that has gone unaddressed for decades.
Lead Flashing on Eastleigh Chimneys
Lead flashing failure is the most common chimney repair call from Eastleigh. A properly flashed chimney uses four lead components — front apron, side soakers and step flashings, back gutter — and when any of these fail, water enters the roof structure at the chimney/roof junction and tracks well into the interior before appearing as a damp patch. We replace lead to the Lead Sheet Association specification using correct-weight lead: 4 code minimum for cover flashings, 5 code for back gutters.
Repointing and Pot Replacement in Eastleigh
Chimney repointing on Eastleigh's Victorian and Edwardian stock requires lime mortar — the original construction material — rather than rigid modern cement. Using cement on a lime mortar chimney causes spalling of the brickwork as the two materials move at different rates in temperature change. On post-war properties with cement mortar stacks, we use a flexible modified cement mix. All repointing specifications are included in the written quote.

What Happens When You Book a Chimney Survey
We survey from a ladder at the eaves and from scaffold where the stack height requires it. We inspect all four lead elements (apron, soakers, step flashings, back gutter), the mortar condition on all four faces, pot stability and cap condition. We photograph every defect. The written survey report classifies findings by urgency — immediate repair, monitor within 2 years, or longer-term consideration. Most Winchester chimney surveys take 30-45 minutes.
