Chimneys are the most exposed part of any roof — they take the full force of wind, rain and frost while standing above the protection of the roof slope. We repair, repoint, reflash and rebuild chimney Serving Ealing and all surrounding areas in Ealing.
Chimneys are the most exposed part of any roof — they take the full force of wind, rain and frost while standing above the protection of the roof slope. We repair, repoint, reflash and rebuild chimney stacks across West London, using materials and methods appropriate to the age and style of your property.
Every chimney repair in Ealing starts with a close inspection from scaffold or tower level. We check mortar joints, flashing condition, pot stability, rendering, and the internal flue lining where accessible. In Ealing, the most common finding is deteriorated mortar joints on chimney stacks across Haven Green.
Repointing replaces deteriorated mortar without disturbing the brickwork — it is the right approach when the bricks themselves are sound. If bricks are spalling, the stack is leaning, or frost damage has broken the structural bond, a partial or full rebuild is necessary. In Ealing, approximately 70% of chimney work is repointing and 30% is partial rebuild.
London's urban heat island creates extreme thermal cycling — roof surfaces in Ealing can swing 40°C between summer peaks and winter lows. Lead flashings expand and contract with every cycle, eventually fatiguing and cracking at the fold lines. We install code 4 minimum lead with adequate expansion provision.
Edwardian terraces around Haven Green and Ealing Broadway station, with larger Victorian villas on Castlebar Road and The Park. 1930s semis dominate South Ealing and Northfields. Post-war infill along Uxbridge Road. For chimney repairs work in Ealing, this housing profile means we commonly encounter Edwardian clay tile slip on steep pitches, flat roof failures on rear extensions, chimney repointing needed on exposed Victorian stacks along the Broadway corridor.
The streets of Ealing — including Haven Green, Castlebar Road, The Park — have roofing characteristics that reflect their construction era and the specific exposure conditions of Ealing. Ealing sits on relatively flat ground west of central London, exposed to prevailing south-westerly weather systems that track up the Thames corridor.

Standard chimney repointing in Ealing costs £300–£600 depending on stack size and access. If the flashing also needs replacing, add £200–£400. A full stack rebuild typically costs £800–£2,000+.
On properties built before 1930, lime mortar is essential — cement is too rigid for older brickwork and causes spalling. On post-war properties, a cement-lime mix is appropriate. We specify the correct mortar for your Ealing property's age.
If the flue is lined and the damage is limited to external pointing, continued use is generally safe. If mortar has failed internally or the stack is structurally compromised, the chimney should not be used until repaired.
In Ealing, exposed chimneys typically need repointing every 15-25 years. South-west facing stacks that take the prevailing weather deteriorate faster. North-facing stacks in sheltered positions can last 30+ years between repointing.
In most cases, yes. Chimney work requires stable access at roof level. We use scaffold towers for single stacks and full scaffold for terrace properties where party wall access is needed.
Yes — we remove redundant chimney stacks and weather the remaining opening. This eliminates ongoing maintenance costs and prevents future water ingress. A structural support must be installed at ceiling level before removal.
Thermal cycling is the primary cause in Ealing — lead expands and contracts with temperature changes until fatigue cracks appear. Poor original installation, inadequate step size, and mortar-only flashings (no lead) are also common causes.
Ealing's roofing heritage reflects its growth as a Victorian and Edwardian suburb. The earliest surviving roofs on properties around Haven Green and Ealing Broadway date from the 1880s — handmade clay peg tiles on steep pitches with decorative ridge tiles that are now almost impossible to source new. The 1930s building boom brought concrete interlocking tiles to the newer estates across Pitshanger, Northfields and South Ealing, and these roofs are now 85-90 years old and approaching the end of their design life.
Ealing's tree-lined streets create specific seasonal roofing challenges. Autumn brings heavy leaf fall from the mature London planes, limes and oaks that shade residential streets — blocked gutters, valley obstructions and moss-promoting debris accumulation are the predictable result. Winter frost affects the older clay tile stock more severely than modern concrete — water trapped in micro-cracks expands and spalls tile surfaces, a process that accelerates once the protective patina is lost.
A well-maintained roof in Ealing directly affects property value. With average house prices in W5 exceeding £700,000, a deteriorating roof can reduce sale value by £15,000-25,000 — far more than the cost of timely repair or replacement. Buyers and surveyors in Ealing are experienced enough to spot deferred roof maintenance, and mortgage lenders will flag roof condition on valuation reports.
Chimney repair always starts with a close inspection from scaffold or tower level. We check every mortar joint for depth and integrity, examine the flashing condition at every junction, test pot stability, assess rendering condition, and look for signs of structural movement or lean. We photograph everything and provide a written report before quoting. This inspection typically takes 30-45 minutes and is included free as part of our quoting process.
The mortar specification for chimney repointing depends on the age of the brickwork. Pre-1930 chimneys require lime mortar — NHL 3.5 or NHL 5 hydraulic lime mixed with sharp sand. Using cement mortar on old brickwork causes the softer bricks to spall because the rigid mortar cannot accommodate thermal movement. Post-war chimneys can use a cement-lime mix (1:1:6 or 1:2:9). We never use neat cement for any chimney repointing — it is too rigid, too impermeable, and causes long-term damage.
Chimney repointing carries our 5-year workmanship guarantee. Lead flashing replacement carries a 10-year guarantee. Stack rebuilds carry a 10-year structural guarantee. These guarantees reflect the expected lifespan of properly specified work — lime mortar repointing should last 15-25 years, and lead flashings 80-100 years.
