Free Survey →Cheltenham's period housing carries some of the oldest lead flashings in Gloucestershire — and the escarpment climate accelerates their deterioration.
Much of Cheltenham's Regency and Victorian housing has original lead flashings now 60–100 years old. These are well past end of design life. Replacement is the only correct solution.
South-westerly fronts carry more moisture than sheltered inland locations. North-facing chimney stacks see higher thermal cycling, which fatigues lead faster than the UK average.
Pre-1920 Cheltenham properties use lime mortar. Flashings pointed with cement on these buildings pull out as the structure moves, creating the gap that allows water ingress.
Properties in Cheltenham's six conservation areas require appropriate lead specification and lime mortar. We understand these requirements and never substitute on period property work.
These are guide prices for the most common leadwork jobs in Cheltenham. All include Code 4 lead, correct mortar for the property type, patination oil and a written guarantee. Scaffold is included where required.

Correctly installed Code 4 lead lasts 25–35 years. North-facing stacks see 20–25 years. We use Code 4 lead as a minimum — Code 3 has a significantly shorter lifespan and is not appropriate for period property work in Cheltenham.
South-westerly fronts off the Cotswold escarpment carry more moisture than sheltered inland locations. North-facing chimney stacks and valley flashings experience higher thermal cycling, accelerating lead fatigue and haunching failure compared to the UK average.
Haunching is the mortar fillet sealing the top edge of lead flashing to brickwork. When it fails, water enters behind the flashing. It is one of the most commonly missed failure points in roof inspections. We check it as standard on every Cheltenham chimney survey.
No. Lead flashing tape has a service life of 3–8 years in Cheltenham's climate. It is not acceptable on conservation area or listed building work. We use Code 4 lead on all permanent repairs.
Yes. Stepped flashings on pre-1920 Cheltenham properties are pointed with lime mortar. Cement mortar on soft historic brickwork causes cracking as the building moves. We specify the correct mortar on every job.
Yes. Patination oil prevents white carbonate staining running down the roof below and provides initial weather protection while the lead oxidises. We apply it as standard on all new lead installations.
