Chimneys and flashings are critical components of your roof's weatherproofing system. With over 18 years of experience serving Ashford Kent and surrounding areas, A.P.T. Builders specializes in chimney repairs, professional repointing, and expert lead flashing installation. From historic properties in Canterbury to modern homes in Maidstone, we protect your property from water ingress with quality craftsmanship and proven techniques.
Kent's weather conditions can be harsh on chimneys, especially in exposed locations like Dover, Folkestone, and Margate. From crumbling brickwork to deteriorated pointing, our expert team handles all aspects of chimney maintenance and repair across Kent. Whether your property features a traditional Victorian chimney in Canterbury or a modern stack in Ashford, we provide reliable solutions that stand the test of time.
Mortar joints break down over time, allowing water ingress that damages brickwork and causes interior damp.
Frost damage causes brick faces to flake and crumble, particularly on exposed chimney stacks.
Thermal stress and weather exposure crack chimney pots, allowing rain penetration down the flue.
Wind exposure and foundation settlement can cause stacks to lean, creating structural concerns.
Deteriorated lead or mortar flashing allows water to seep between chimney and roof.
Plants and moss growing from chimney joints indicate moisture problems and accelerate deterioration.
Lead flashing is essential for creating watertight seals where your roof meets chimneys, walls, valleys, and other features. Across Kent properties from Sevenoaks to Sittingbourne, proper lead flashing prevents costly water damage. Our skilled craftsmen use traditional techniques combined with modern materials to ensure lasting weatherproof protection for your Kent home or business.
Properly installed lead flashing can last 60-100+ years, outlasting most other roofing materials with minimal maintenance required.
Lead's natural properties create completely watertight seals that withstand Kent's harshest weather conditions year after year.
Lead can be dressed into complex shapes and details, perfect for historic buildings and intricate architectural features.
Essential for listed buildings and conservation areas, lead maintains authentic period character while providing modern protection.

Don't wait for serious water damage. These warning signs indicate your chimney or flashing needs professional attention:
Water stains on ceilings or walls near the chimney breast indicate failing flashing or chimney weatherproofing.
Gaps between bricks where mortar has fallen out, especially on the chimney's exposed sides.
Salt deposits on brickwork caused by water penetration, indicating serious moisture problems.
Visible cracks, tears, or splits in lead flashing allowing water through to roof timbers.
Gaps between flashing and brickwork or roof surface where weatherproofing has failed.
Plants, moss, or weeds growing from chimney joints indicate trapped moisture and deteriorating mortar.
Fragments of brick or mortar in gutters or on the roof below the chimney stack.
Water entering the property during or after rainfall, especially around chimney areas.
