Specialist lead flashings, valleys and chimney work. All to Lead Sheet Association standards. Covering SO40.
Totton's damp Test Valley location accelerates the deterioration of lead flashing pointing — the mortar that holds lead step flashings into the brick course softens faster in the persistent moisture here than in drier locations. When the pointing fails, the lead lifts away from the stack and water tracks directly into the roof space. We carry out lead flashing replacement and re-pointing across all Totton property types.

Request Free QuoteLead flashings in Totton 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 Test Valley river humidity — one of the dampest locations in Hampshire, accelerated oxidation of the lead surface. On waterfront and exposed properties, the higher salt concentration in Totton 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.
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 Totton property exposed to Test Valley river humidity — one of the dampest locations in Hampshire leads to early failure and repeat calls. All leadwork is carried out to Lead Sheet Association standards.
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 Totton 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.

Mastic is a temporary sealant that fails within a few years. Correctly dressed lead lasts 50 to 80 years. We do not use mastic as a substitute for lead work.
