Leadwork in Chandler's Ford

Chandler's Ford's large 1930s detacheds in Hiltingbury have some of the most complex leadwork requirements in Hampshire — multiple valley runs, multi-stack chimneys and dormer flashings on substantial properties. Lead valley failure on a Hiltingbury detached with three valley runs requires careful sequencing and correct sizing specification. We carry out complex leadwork on large properties regularly and have the experience for multi-valley, multi-chimney jobs.

Lead Flashing Failure in Chandler's Ford

Lead flashings in Chandler's Ford fail through three primary mechanisms: thermal movement cracking where flashing is fixed too tightly without movement provision, failed mortar pointing that secures step flashings to the brick course, and in well-drained elevated ground north of Southampton with mature tree canopy, accelerated oxidation of the lead surface. On waterfront and exposed properties, the higher salt concentration in Chandler's Ford accelerates surface deterioration faster than inland equivalents. We identify the failure mode during inspection and address the cause rather than patching the symptom with mastic.

Correct Lead Specification for Chandler's Ford

Lead code specification is critical to longevity. Code 4 for step flashings and soakers. Code 5 for back gutters, valleys and bay roofs. Code 6 and above for parapet gutters and flat roof sections. We specify the correct code for each application — using undersized lead on a Chandler's Ford property exposed to well-drained elevated ground north of Southampton with mature tree canopy leads to early failure and repeat calls. All leadwork is carried out to Lead Sheet Association standards.

Why We Never Use Mastic in Chandler's Ford

Mastic sealant applied over failed lead flashings is a temporary patch that lasts 2 to 3 years before failing again. Correctly dressed and fixed lead lasts 50 to 80 years. On any Chandler's Ford property we work on, mastic is not used as a substitute for correct lead work. Where we find previous mastic applications, we strip them out and execute the junction correctly in properly dressed lead.

Disruption, Mess & Weather

Localised, external work — minimal noise and little waste — with no need to be home. You do not need to stay home for external work - we just need power and access agreed in advance.

Leadwork runs year-round; the junction is made watertight before we leave each day. Chandler’s Ford’s mature tree canopy means heavy autumn leaf fall and quick moss regrowth on shaded, north-facing slopes.
