A careful look at the chimney stack at your property in Clapham Junction, and put it all in a written report with photographs.

Chimney surveys for homes and businesses in Clapham Junction
Many homes have chimneys that are no longer used. A disused stack still needs looking after. If it has been capped without ventilation, damp can build up inside it. Our survey looks at how each unused stack has been capped and checks the breasts for damp. The report sets out what we found and what we recommend. We are often asked to look into signs that a stack is leaning and unused flues sealed without airflow, on lead flashings, shared and party-wall stacks and brick chimney stacks.
London has Victorian and Edwardian terraces in almost every borough, many with Welsh slate roofs, shared chimney stacks and parapet or valley gutters. Good slates can last over a hundred years, yet the nails often give out first and let slates slip. Homes in Clapham Junction are no exception. Shared chimney stacks and the lead around them are just as important to check.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

- Hidden damage within the stack
- The inside of the flue, which needs a sweep or flue specialist
- Hidden sides of a shared stack

Questions from Clapham Junction
Is my home in Clapham Junction listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Will parking be an issue for a roof survey in Clapham Junction?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available as you book.
Do you carry professional indemnity insurance?
We are covered by professional indemnity and public liability insurance.
Does the weather affect the survey?
It depends on the weather and the survey. In strong wind or heavy rain, a drone cannot fly and access may not be safe, so we’d move the date with you.
Does this replace a RICS home survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Should a redundant chimney be removed?
It depends on its condition and your plans. The survey shows its condition and how it’s been capped. In a conservation area or on a listed building, changes may need consent.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
What we are asked to look at in Clapham Junction
Aerials and dishes are frequently fixed to stacks. The extra load in wind can work bricks and joints loose. We check fixings on the stack as part of the survey.
People normally book a survey when they’ve noticed one of these:
- Cracked or missing flaunching
- Frost-damaged brickwork on the stack
- Signs that a stack is leaning
- Flashings pulling away from the stack
Living close to Imperial Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn.
Questions to ask before booking
- Whether the inside of the roof is included
- Whether they hold professional indemnity and public liability insurance
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether you can ask questions once you have the report

Local roofs in Clapham Junction
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them. Historic houses like Carlyle's House, about 1.4 miles north, show how far back building in the area around Clapham Junction goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
For landlords with property near Clapham Junction station, a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak. If you live in an older home near Clapham Welsh Presbyterian Church, its chimney, valleys and lead work are likely to be the parts that need attention first.

What else we do in Clapham Junction
Before and after the survey
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Check with the council before altering a stack in a conservation area or on a listed building
- Use the report as a baseline for future checks
- Have brackets on the chimney checked
- Photograph damp patches with the date
If the stack is shared, you can pass the report to your neighbour. It shows what we found and where, as far as we could see.
Watch for damp or staining on chimney breasts. Early signs are easier to trace.
How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. Most visits take about one to two hours at a typical home, though large, tall or awkward roofs take more time. From the street, a London terrace usually shows only its front slope or parapet, so a visit in Clapham Junction moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- We start with the details: how many stacks, whether any are shared and any signs of damp.
- The stacks are looked at from ground level, from windows and from other safe vantage points.
- Every part we can see is checked: pots, cowls, flaunching, pointing, bricks and flashings.
- We check the chimney breasts and the stack in the loft space where we can reach them.
- The findings are written up with photos and recommendations and emailed to you.
How to prepare
- Have any paperwork from past roof work to hand
- Move anything stored under the loft hatch
- Unlock side gates and any roof access doors

Different roofs, different checks
Lead flashings
Some older stacks have mortar fillets instead of lead. They crack with age, and we check them too.
Flaunching
The sloping mortar around the pots is called flaunching. Cracks in it let water into the stack.
