Chimney repair work in Barton covers the full range of common conditions on post-war stock: mortar joint failure requiring repointing; lead flashing replacement where step, apron or back gutter flashings have fatigued through Devon’s thermal cycling; chimney pot displacement or cracking; and structural stack movement where the masonry itself has deteriorated. We survey all four conditions on every chimney assessment in Barton.
1960s code 3 lead on barton chimney stacks — now 60 years old and typically showing stress cracking on fold points. Post-war and 1960s estate housing with concrete interlocking tile at or approaching nail-sickness age. The correct mortar specification for Barton’s post-war chimney stock is hydraulic lime (NHL 2 for sheltered positions, NHL 3.5 for exposed faces). Cement mortar on pre-1900 masonry causes spalling and water penetration at mortar-to-brick interfaces — we use lime mortar as standard on all Barton period chimney work.
Lead code specification matters for Barton chimney flashing replacement. Code 4 (1.80mm) for step and apron flashings. Code 5 (2.24mm) for back gutters where standing water is present. Stainless steel clips on all exposed flashing faces — mortar tuck alone does not prevent thermal expansion from opening the joint. We apply patination oil to all new lead on Barton installations as standard.

Code 4 for step and apron flashings. Code 5 for back gutters. We specify these as standard on all Barton chimney lead work.
Always — the back gutter is the most frequently overlooked element and is typically at the same age and condition as the step flashings.
Visible mortar loss, white calcium staining on the stack face, and internal damp near the chimney breast after rainfall are the main indicators.
