Chimney survey in Clapham: what you get
Each stack is looked at from the safest viewpoints available: the ground, nearby windows and higher points, and the roof space where it is safe. A drone inspection is part of our Premium Survey where applicable. If we can’t see part of the stack, the report makes that clear. Each defect is recorded with a photo and a plain description. Common reasons to book are disused chimneys trapping moisture and flashings pulling away from the stack, across chimney pots and cowls, flaunching and lead flashings.
Much of London’s housing is flats, in converted houses or purpose-built blocks, where the roof is normally a shared part of the building. Whoever looks after the building needs a clear picture of the roof, chimneys and gutters, in Clapham as anywhere. A defect on a shared roof can reach more than one flat. With a written report and photos, everyone can plan from the same facts.
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.

When to book a survey in Clapham
Stacks that were used for open fires for many years can weaken from the inside. Flue gases and damp can break down the mortar, sometimes more on one side than the other, which can make a stack lean.
Things that often lead to a survey include:
- Spalled or crumbling bricks
- Signs that a stack is leaning
- Cracked or missing flaunching
- Damaged chimney pots and cowls
Take an older house close to St Paul's Church: its roof may have old fixings, lead flashings and chimneys that need a closer look.
What to check before booking
- Will the report include photos?
- Their track record with similar roofs
- Which limits apply to the survey
- Their report turnaround times
Tips that help
Most of what helps is simple and safe from ground level. Our suggestions:
- Check your stacks from ground level after strong winds
- Keep the report to compare against at the next survey
- Photograph damp patches with the date
- Never climb onto the roof to look at a chimney
If the report recommends a structural engineer, a sweep or a Gas Safe registered engineer, it will say why. It gives them a clear starting point.
Keep an eye on chimney breasts for new damp patches. The sooner damp is spotted, the easier the cause is to find.
Checking the roof from ground level
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
What a chimney survey doesn’t cover
Before you book, it is worth knowing what a survey will not do:
- Whether a gas appliance or its flue is safe
- A structural engineer’s assessment
- Parts of the stack that can’t be seen safely or belong to a neighbour we can’t access
Not sure which survey suits your roof? You can call 07833 053749 or email us and we will tell you before booking. The full list of what we check.

Questions from Clapham
Can a landlord with a rental near Clapham High Street station book a roof survey?
Yes, that’s a common request. Let us know whether a tenant or an agent will let us in, and we can send the report to you or your agent.
Is parking a problem for a survey in Clapham?
Parking in Clapham, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
How can you see the top of the stack?
We look from ground level, from windows and from the loft where it’s safe. A drone inspection is part of the Premium Survey where applicable. Any area we couldn’t view is noted.
Which parts of the chimney do you look at?
The whole stack, as far as it can be seen safely: from the pots and flaunching down to the flashings. Leaning, unused stacks and damp on chimney breasts are recorded too.
Does the weather affect the survey?
It depends on the weather and the survey. Strong wind or a downpour can make access unsafe and ground a drone, and we’d agree another day.
Will you go up on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where applicable, and the report records anything we couldn’t see.
Can you survey a chimney stack we share with next door?
Yes. Many houses share stacks with a neighbour. We survey what we can see safely, and note anything that seems to involve next door.
The survey, step by step
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely. The survey usually takes about one to two hours for most homes, a little longer where there are several stacks. In a London area like Clapham, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can be seen safely from the ground, windows, the loft and, where it’s safe, the roof itself.
- First we talk through the stacks, their history and any problems.
- Each stack is inspected from safe positions outside.
- We photograph and record the pots, flaunching, pointing and flashings.
- We look for damp on chimney breasts and in the loft space.
- The report, with photographs and recommendations, is emailed to you.
Before we arrive
- Unlock side gates and any roof access doors
- Keep pets in another room
- Tell us about parking before the day

What else we do in Clapham
Roofs, chimneys and gutters in Clapham
About 1.9 miles north-west lies Carlyle's House, a reminder of how long the area around Clapham has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. If your home in Clapham is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them.
If you live near a park such as Larkhall Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls. If you let a flat or house near Clapham High Street station, a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak.
