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 Hammersmith and all surrounding areas in Hammersmith & Fulham.
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 Hammersmith 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 Hammersmith, the most common finding is deteriorated mortar joints on chimney stacks across King Street Hammersmith.
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 Hammersmith, approximately 70% of chimney work is repointing and 30% is partial rebuild.
London's urban heat island creates extreme thermal cycling — roof surfaces in Hammersmith 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.
Mix of Georgian riverside properties on Upper Mall and Hammersmith Terrace, Victorian terraces around Brook Green and Ravenscourt Park, and 1960s council estates near the flyover. The area between King Street and the river has some of West London's most valuable period housing. For chimney repairs work in Hammersmith, this housing profile means we commonly encounter Thames riverside properties on Upper Mall face flood risk and persistent damp — roof timbers show moisture migration from ground level. Urban heat island drives extreme thermal cycling on lead and fla
The streets of Hammersmith — including King Street Hammersmith, Upper Mall, Hammersmith Terrace — have roofing characteristics that reflect their construction era and the specific exposure conditions of Hammersmith & Fulham. As an inner London borough flanking the Thames, Hammersmith & Fulham experiences the full urban heat island effect — summer roof surface temperatures regularly exceed 60°C, driving extreme thermal cyc

Standard chimney repointing in Hammersmith 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 Hammersmith 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 Hammersmith, 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 Hammersmith — 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.
Hammersmith and Fulham packs more Victorian terraced housing per square mile than almost anywhere in London, and the roofing challenges reflect this density. Fulham's grid streets between Fulham Palace Road and Wandsworth Bridge Road contain thousands of two-storey terraces with the characteristic butterfly roof profile — an M-shaped valley roof where all rainwater channels to a concealed central valley. This design was elegant and space-efficient when built in the 1880s; 140 years later, those central valleys are the most common single point of failure we see across the borough.
As an inner London borough flanking the Thames, Hammersmith and Fulham experiences the full urban heat island effect. Summer roof surface temperatures regularly exceed 60°C, driving extreme thermal cycling on lead, zinc and felt that accelerates material fatigue. The Thames frontage along Hammersmith and Fulham reaches means riverside properties face persistent damp exposure and occasional flood risk. Winter storms funnel between terraced streets, creating localised wind loading that displaces ridge tiles and lifts flashings.
Fulham property prices have risen dramatically — a standard Victorian terrace that sold for £400,000 fifteen years ago now commands £1.2-1.5 million. At these values, a sound roof is a non-negotiable expectation from buyers, mortgage lenders and insurers. The cost of a complete butterfly valley replacement and roof overhaul on a Fulham terrace is typically £5,000-8,000 — a fraction of the value it protects.
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.
