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.
Finchley is quintessential North London suburbia — tree-lined avenues of 1920s and 1930s semi-detached houses with hipped roofs covered in concrete tiles. East Finchley has a distinct pocket of Arts and Crafts cottages near the tube station with handmade clay tile roofs and half-timbered gables. North Finchley's larger detached houses along Woodside Park feature clay plain tiles and prominent chimney stacks. The mature tree canopy creates heavy leaf-fall and persistent shade. The chimney stacks on these properties have been exposed to over a century of London weather. In Finchley 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 Ballards Lane, High Road N12, High Road N2, Regent's Park Road, East End Road, Long Lane exhibit all of these in varying combinations.
The choice of mortar is critical for Finchley 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 Finchley'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 Finchley, where extensive moss colonisation from shaded tree-lined streets is finchley's signature issue — it lifts tile edges and retains moisture against the surface, 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.

Extensive moss colonisation from shaded tree-lined streets is Finchley's signature issue — it lifts tile edges and retains moisture against the surface. Hip and ridge mortar failure on 1930s roofs, sagging felt underlay on re-roofed properties, valley tile displacement from thermal movement, and cracked concrete tiles from decades of freeze-thaw cycling are all regular repairs.

"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 Finchley. 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 Finchley. 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 Finchley'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.
