Chimney survey in Mill Hill, Greater London
A survey of chimney stacks, pots, flashings and flaunching across Mill Hill, using drones and thermal imaging where applicable. Call or email for a price.
- Disused chimneys trapping moisture
- Damaged chimney pots and cowls
- Spalled or crumbling bricks
Before and after the survey
From years of surveys, a few habits stand out:
- Check fixings on the stack are secure
- Look at the chimneys with binoculars after a storm
- Keep track of stains on chimney breasts
- Check that disused chimneys can still breathe
With a shared stack, the report can help when talking to next door. It shows what we found and where from the viewpoints we used.
Have aerial and dish brackets on the stack checked and taken off if they’re no longer needed. Removing unused fixings takes strain off the brickwork.
Chimney surveys for homes and businesses in Mill Hill
Each stack is looked at from the safest viewpoints available: from ground level, from windows and vantage points, and from the loft where there’s access. With our Premium Survey, a drone inspection is included where it applies. If we can’t see part of the stack, the report makes that clear. Every defect we find is photographed and described in plain words. We survey brick chimney stacks, lead flashings and flaunching, and people most often book us about cracked or missing flaunching and spalled or crumbling bricks.
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 Mill Hill has one, it needs checking from somewhere that can actually see it.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Prices for chimney surveys in Mill Hill
We confirm the price for your roof before booking. These are the things that affect it:
- How tall the building is and how easy the roof is to see
- Whether it is a home or a commercial building
- Any need for thermal images or a drone flight
- The size of the roof
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.

The more you let us know, the easier it is to price the survey. When you contact us, tell us:
- The address and postcode of the property

Common questions in Mill Hill
Does a conservation area affect roof work in Mill Hill?
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.
I let a flat near Mill Hill Broadway station. Can you check the roof?
Yes. We survey roofs for landlords, letting agents and managing agents as well as owners. You can phone 07833 053749 or use the contact form with the address and what you need.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
What happens after the survey?
You will receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How much does a chimney survey cost in Mill Hill?
Our price is from £150, including VAT. The final figure depends on the roof and the package you choose.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone.
What’s in the report?
A report with photographs, covering the condition of the chimney stack, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Chimney surveys around Mill Hill
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Mill Hill is one of them, bay roofs, hips and later dormers each have their own details. Knowing the covering helps explain which parts of a roof are likely to need work first. The wider area around Mill Hill has a long history of building, with Heath Hall about 4 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you run a business near Broadwalk Centre, a written record of the roof’s condition helps you plan maintenance rather than react to leaks. For site and facilities teams at buildings such as St Paul's CofE Primary School NW7, large buildings have long gutter runs and big roofs that need checking like any other. If you own one of the older houses in the streets near St Paul's Church, the nails, lead and mortar on the roof may be wearing out even where the slates or tiles look fine.

What we do, step by step
Once we have finished looking, we write up our findings as a written report with photos. On timing, most surveys take between one and two hours for most homes, a little longer where there are several stacks. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- We start by noting which stacks are in use, shared or causing concern.
- The flashings and the roof around each chimney are inspected.
- We check the flaunching and pots on every stack.
- Any lean, spalling or worn pointing is recorded.
- The report explains the condition and which work is most urgent.
Getting ready for the survey
- Leave a clear route to the loft
- Find any records of previous roof work
- Have any questions written down, so nothing gets missed
Arrange a survey
If you have photos of the roof, send them over. Take them safely from ground level or a window, and please don’t climb up for a closer look. To get started, phone 07833 053749 or use the contact form.

Chimney pots and cowls
Each pot is bedded into the flaunching, often with a cowl or cap on top. The survey looks for cracked, loose or missing pots and cowls.
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.
