Repointing, lead flashing, chimney stack repairs and pot replacements. We make your chimney weathertight and safe.
North London's skyline bristles with chimney stacks — a legacy of the Victorian and Edwardian building boom. After a century or more of weather exposure, mortar joints erode, flaunching cracks, flashings split, and pots loosen. We handle everything from repointing to full rebuilds.
Highgate is one of London's most prestigious hilltop villages with an eclectic mix of grand Georgian houses, Victorian gothic villas, and significant modernist homes from the 1930s Highpoint era. The Highgate conservation area is extensive and many properties are individually listed. Roofs range from original Welsh slate on Georgian townhouses to handmade clay tiles on Arts and Crafts properties and copper standing-seam on modernist buildings. The chimney stacks on these properties have been exposed to over a century of London weather. In Highgate specifically, we most frequently diagnose eroded mortar joints (lime mortar on pre-1920 properties, cement mortar on later stock), cracked flaunching around pot bases, lead flashing fatigue at step and apron joints, and structural movement in chimney stacks sitting on London clay subsoil. Properties on Highgate High Street, North Hill, Highgate West Hill, Hampstead Lane, Southwood Lane, The Grove exhibit all of these in varying combinations.
The choice of mortar is critical for Highgate chimney repointing. Pre-1920 properties with soft lime mortar joints must be repointed in lime mortar — not modern cement, which is harder than the surrounding bricks and causes spalling. Later properties can accept cement-based mortars. In Highgate's conservation areas, lime mortar is often a planning requirement. We use NHL 3.5 or NHL 5 hydraulic lime depending on exposure, mixed on site to ensure correct consistency and colour matching.
London's thermal cycle — summer temperatures exceeding 30°C and winter frosts below -5°C — causes lead flashings to expand and contract by several millimetres every day. Over decades, this fatigue cracks the lead at corners and step joints. In Highgate, where listed building consent requirements complicate almost every roof repair in highgate, chimney flashing failure is one of our most common repair calls. We replace failed flashings with minimum code 4 milled lead, properly stepped and wedged into raked mortar joints, with adequate provision for thermal movement.

Listed building consent requirements complicate almost every roof repair in Highgate. Heavy leaf and debris accumulation from mature woodland, specialist slate matching on Georgian properties, copper gutter and flashing patina preservation, and the structural complexity of Victorian gothic roof forms with multiple valleys and hips all require experienced, specialist roofers.

"Full chimney repoint in lime mortar plus new lead flashing and re-flaunching. The stack had been neglected for decades. Looks brand new and no more damp on the chimney breast."
"Chimney pot was loose and rocking in the wind. They re-flaunched, fitted a new pot, and repointed the top six courses while they were up there. Scaffold was up and down in two days."
"Removed a redundant chimney stack down to roof level and capped it properly. Previous owner had left it slowly crumbling. They tiled over it and you'd never know a chimney was there."

Spring (March–May): The ideal time for a professional inspection in Highgate. Winter damage is visible — cracked mortar, displaced tiles, failed flashings — and you're ahead of the autumn storm season. Book a free inspection now and address any issues before they worsen over summer.
Summer (June–August): The best conditions for major roofing work in Highgate. Dry weather allows full strip-and-retile projects, flat roof installations, and chimney rebuilds. Lead work is easier in warm temperatures when the metal is more malleable. If you're planning a roof replacement, summer is the optimal window.
Autumn (September–November): Clear gutters and valleys of leaf debris — critical in Highgate's tree-lined streets. Check ridge tiles and flashings before winter storms arrive. A pre-winter roof check costs nothing (we do it free) and can prevent expensive emergency repairs in December and January.
Winter (December–February): Emergency repairs only where possible. Frost, ice, and short days limit what can be safely done on a roof. However, if you have an active leak or storm damage, we respond same-day regardless of conditions. Call 0203 538 0907 any time — 24/7 emergency line.
