Chimney surveys for homes and businesses in Denmark Hill
Our survey covers the structure of the stack and its weathering details. It’s not a flue inspection, a chimney sweep or a gas safety inspection. For the flue itself, you’ll need a sweep or, for gas appliances, a Gas Safe registered engineer. If something we see points to the flue, we’ll say so. Common reasons to book are mortar washing out of the joints and lifted or split lead flashings, across chimney pots and cowls, brick chimney stacks and shared and party-wall stacks.
Many London terraces have a butterfly roof, with two slopes meeting in a central valley gutter that drains to the rear. Hidden behind the parapet, that gutter can block or split without anyone seeing it. If your home in Denmark Hill has one, it needs checking from somewhere that can actually see it.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that is said too.

Denmark Hill: your questions answered
I let a flat near Denmark Hill station. Can you check the roof?
Yes. We survey roofs for landlords, letting agents and managing agents as well as owners. Just phone 07833 053749 or email us with the details, and we’ll talk through which survey suits.
Will parking be an issue for a roof survey in Denmark Hill?
It depends on the street. If Denmark Hill has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
What happens next?
You will get the report by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed, and anything out of sight is recorded in the report.
How do I arrange a chimney survey in Denmark Hill?
Simply ring 07833 053749 or email us. We will ask a few questions, confirm the price and agree a date.
What do you check on a chimney?
Every part of the stack we can see from safe positions: pots, cowls, flaunching, pointing, bricks and flashings. Leaning, unused stacks and damp on chimney breasts are recorded too.
Do you test for asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
What this survey cannot tell you
In fairness, there are limits to any roof survey:
- Structural calculations for a leaning stack
- What’s inside the brickwork or behind render, without opening up
- The inside of the flue, which needs a sweep or flue specialist

Practical tips
There’s plenty you can do without going near the roof. Here’s what helps most:
- Ask about consent before removing a chimney on an older property
- Don’t use a ladder to reach the stack yourself
- Book a sweep for flues that are in use
- Keep track of stains on chimney breasts
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.
Have aerial and dish brackets on the stack checked and taken off if they’re no longer needed. Less load on the stack means less strain in wind.
What we’re asked to look at in Denmark Hill
Years of fires can affect the mortar inside a stack. Mortar can deteriorate unevenly from flue gases and moisture, which can make a stack lean.
We are often asked to look at:
- Flashings pulling away from the stack
- Gaps in the mortar around the pots
- Mortar washing out of the joints
- Redundant stacks capped without ventilation
For an older house near a landmark such as St Matthew's Camberwell, its roof may have old fixings, lead flashings and chimneys that need a closer look.

Chimney surveys in Denmark Hill: local notes
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them. About 2.6 miles south lies Kingswood House, a reminder of how long the area around Denmark Hill has been built on. 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.
For businesses in and around places like Surrey Quays Shopping Centre, a dated report on the roof is useful for planning and for any lease discussions. Anyone responsible for a site like Lyndhurst Primary School will know that large buildings have long gutter runs and big roofs that need checking like any other.

What happens on the day
The aim of the visit is simple: to look at the chimney stack as closely as is safe and record what we find. Notes and photos go into the written report. The visit normally takes between one and two hours at a typical home, with bigger or more complicated roofs taking longer. From the street, a London terrace normally shows only its front slope or parapet, so in Denmark Hill we work round the house, using the street, the windows, the loft and any safe vantage point behind it. 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.
- Each chimney is viewed from wherever it can be seen safely.
- Every part we can see is looked at: pots, cowls, flaunching, pointing, bricks and flashings.
- Inside, we look for damp on chimney breasts and in the loft where there is safe access.
- The findings are written up with photographs and recommendations and emailed to you.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- Move anything stored under the loft hatch
- Make a note of anything you’d like us to look at

Advice
Roof by roof
Rendered stacks
A rendered stack can mask problems in the bricks below. We look for cracks, hollow areas and staining.
Flaunching
Flaunching is the mortar on top of a stack that holds the pots and sheds water. Cracks in it let water into the stack.
