About our chimney survey in Barnsbury
A damp patch on a chimney breast doesn’t always come from the same place. Water may be getting in at the top through cracked flaunching or an uncapped pot, through the brickwork, or at the flashings. Condensation inside an unventilated stack is another common cause. Our survey checks each of these and records the likely cause. That points the work in the right direction. Typical surveys look at staining on walls around the chimney and gaps in the mortar around the pots, on lead flashings, shared and party-wall stacks and chimney breasts.
Much of London’s housing is flats, in converted houses or purpose-built blocks, where the roof is usually a shared part of the building. Whoever looks after the building needs a clear picture of the roof, chimneys and gutters. Leaks from a shared roof rarely affect just one home. With a written report and photographs, everyone can plan from the same facts.
What you get is a clear record of the chimney stack on the day we saw it. It’s useful straight away, and a good reference for later, for instance when you want to check whether anything has changed.

Before and after the survey
Over many surveys, some simple habits stand out:
- Don’t use a ladder to reach the stack yourself
- Make sure fixings on the stack are secure
- Note any damp on chimney breasts and when it appears
- Check with the council before altering a stack in a conservation area or on a listed building
Once we have been, the findings are written up with photos. It explains the condition of each part of the stack and any damp inside. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Have aerial and dish brackets on the stack checked, and moved if they’re working it loose. Removing unused fixings takes strain off the brickwork.
What we’re asked to look at in Barnsbury
Years of fires can affect the mortar inside a stack. Flue gases and damp can break down the mortar, sometimes more on one side than the other, which can make a stack lean.
A survey makes sense if you’ve noticed:
- Flashings pulling away from the stack
- Signs that a stack is leaning
- Pots or cowls that look unsafe
- Damp patches on chimney breasts
If yours is one of the older homes in the streets near Former Church of St Clement, corroded nails, tired lead and weathered chimney pointing are the things to watch on older roofs.
Questions to ask before you book
- Whether VAT is added on top
- What’s outside the scope of the survey
- When you’ll get the report
- Which parts of the roof they’ll actually see
Chimney surveys in Barnsbury: local notes
About 2.1 miles south lies Dr Johnson's House, a reminder of how long the area around Barnsbury has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Barnsbury is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Whichever you have, the details that tend to fail before the covering itself get the closest look.
Trees in and around Bingfield Park shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching. For landlords with property near Caledonian Road & Barnsbury station, the gap between tenancies is a good time to have the roof looked at.
Barnsbury is about 1 mile north of St Pancras, in Greater London. In Barnsbury, as across Greater London, every roof gets the same careful survey. Across Greater London, we cover Barnsbury.

Landmarks near Barnsbury
Around Barnsbury, our work takes us to homes and buildings near Vaughan Williams Memorial Library, St Mary Magdalene Academy and Bingfield Park and the streets around them. Nearby too are Musical Theatre Academy (0.5 miles north-east) and The White Horse Public House (within half a mile north-west).

What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
What a chimney survey does not cover
We only report whatever is safely visible on the day, so there are some things a survey cannot cover:
- Parts of the stack that cannot be seen safely or belong to a neighbour we can’t access
- Structural calculations for a leaning stack
- Hidden damage within the stack

Your questions about chimney surveys in Barnsbury
How do I find out if my home in Barnsbury is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Will parking be an issue for a roof survey in Barnsbury?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drones can’t fly safely in high wind or heavy rain, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we’ll talk to you about another date.
How long will you be at the property?
Expect it to take about 1–2 hours at most homes, and longer for a large or complex roof. The written report follows by email, on the timescale of your package.
What do you check on a chimney?
The survey covers the pots and cowls, the flaunching, the pointing, the bricks and the flashings. We also check chimney breasts and the stack in the roof space where we can reach. Everything is written up with photos.
What’s the best way to book?
It’s easiest to phone 07833 053749 or send us an email. Tell us the address and a little about the roof, and we’ll point you to the right survey. We survey on weekdays, Saturdays and Sundays.
Do you survey roofs on blocks of flats?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.

What happens on the day
On the day, we start by asking what you’ve noticed and what you need to know. After that, we look at everything we can see safely. The survey normally takes between one and two hours at a house, as part of a look at the roof around the stack. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We go through the chimneys, any damp and any work done on them.
- 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 roof space.
- The report, with photos and recommendations, is emailed to you.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- If the roof is shared, arrange access with whoever manages the building
- Have keys ready for side gates, garages or roof access doors
