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 Teddington and all surrounding areas in Richmond upon Thames.
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 Teddington 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 Teddington, the most common finding is deteriorated mortar joints on chimney stacks across High Street Teddington.
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 Teddington, approximately 70% of chimney work is repointing and 30% is partial rebuild.
London's urban heat island creates extreme thermal cycling — roof surfaces in Teddington 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.
Victorian and Edwardian terraces and semis between the High Street and Bushy Park. Some larger detached properties on Park Road and Broom Road. 1930s housing near Teddington Lock. Conservation area around the town centre. For chimney repairs work in Teddington, this housing profile means we commonly encounter Bushy Park deer population means oak canopy debris loading on roofs along the park edge. Thames Lock proximity creates localised humidity spikes. Victorian terraces with shared party wall flashings —
The streets of Teddington — including High Street Teddington, Stanley Road, Park Road Teddington — have roofing characteristics that reflect their construction era and the specific exposure conditions of Richmond upon Thames. The Thames winds through the borough from Hampton in the west to Kew and Barnes in the east, creating a microclimate with higher humidity than inland areas.

Standard chimney repointing in Teddington 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 Teddington 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 Teddington, 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 Teddington — 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.
Richmond upon Thames has the highest concentration of historic roofing in West London. Georgian townhouses on Richmond Hill carry original Welsh slate roofs that have been patched, repaired and partially replaced over 200+ years. The borough's 73 conservation areas — more than any other London borough — create a planning framework that requires roofing work to use period-appropriate materials, colours and methods. This is not optional — enforcement action for non-compliant roofing materials is actively pursued.
The Thames winds through Richmond from Hampton to Barnes, creating a humidity corridor that accelerates moss growth, lead oxidation and timber deterioration on riverside properties. Richmond Park's 2,500 acres of open ground creates a cold air reservoir that drains downhill toward riverside properties in the early morning hours, causing heavy condensation on roof surfaces. This combination of moisture and temperature fluctuation makes annual roof inspections essential for Richmond properties.
Richmond has some of the highest property values in London outside the central boroughs. Georgian houses on Richmond Hill regularly sell above £2 million, and the roofing specification expected at this price point is correspondingly high. Original Welsh slate, cast lead guttering, lime mortar pointing and hand-dressed flashings are the standard — not premium upgrades. The cost of a heritage-grade re-roof on a Richmond Hill property can exceed £30,000, but the alternative is unthinkable for properties at this value.
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.
Chimney problems show up as damp on the chimney breast or visible mortar decay.
