How a chimney survey works in Sudbury Hill
Our survey covers the structure of the stack and its weathering details. It is not a flue inspection, a sweep or a gas safety check. If you use a fire or a gas appliance, the flue should be checked by a sweep or a Gas Safe registered engineer as appropriate. We will tell you if we see anything that suggests they should take a look. If you are worried about damp patches on chimney breasts and pots or cowls that look unsafe, a survey will tell you what’s going on, on chimney breasts, lead flashings and chimney pots and cowls alike.
Many London terraces have a butterfly roof, with two slopes meeting in a central valley gutter that drains to the rear. From the street you see only a parapet wall, so blocked outlets and split linings go unnoticed until water comes through a ceiling. If your home in Sudbury Hill has one, it needs checking from somewhere that can actually see it.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend.

What you can safely check yourself
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book and it will help the survey.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in.
Do you need a chimney survey in Sudbury Hill?
A stack takes the weather from every direction. Frost works into cracks in the flaunching and pointing, and rain soaks into worn brickwork. Most people book after spotting damp or a loose pot, or before buying.
Here are some of the things we see often:
- A stack that appears to lean
- Frost-damaged brickwork on the stack
- Loose, cracked or missing pots
- Staining on walls around the chimney
Living close to Preston Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
What to check before booking
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Are they insured for the work?
- Whether you can ask questions once you have the report
- What the survey won’t cover
The survey, step by step
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes about one to two hours at a typical home, rising to roughly 3–4 hours on a commercial building. In Sudbury Hill, as in much of London, lots of properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know as you book.
- First you let us know about the chimneys, any damp on the chimney breasts and any worries.
- We inspect each stack from safe viewpoints outside.
- We check and photograph the pots, cowls, flaunching, pointing and flashings.
- We check the chimney breasts and the stack in the loft space where we can reach them.
- We send a written report with photos, the defects found and what we recommend.
Getting ready for the survey
- Leave side gates unlocked
- Note where any stains or damp appear
- Make a note of anything you’d like us to look at
Getting a price
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or send us an email to find out.

What we can’t see
It is a careful look at the chimney stack, not the whole story. Its limits include:
- Parts of the stack that cannot be seen safely or belong to a neighbour we cannot access
- Conditions inside walls
- The inside of the flue, which needs a sweep or flue specialist
If in doubt, phone 07833 053749 or send us an email and we will recommend the right survey. What a survey covers and does not.
Roof types and parts we check
- Chimney breasts
- Lead flashings
- Brick chimney stacks
- Flaunching
- Shared and party-wall stacks
- Chimney pots and cowls
Rented homes, blocks and businesses
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
If the property is let, the agent or a tenant can let us in. Surveys run seven days a week, which can make access easier.
Sudbury Hill questions
Can a landlord with a rental near Sudbury & Harrow Road station book a roof survey?
Yes, that’s a common request. We just need to know who will give access, and the report can go straight to you or your agent.
How do I find out if my home in Sudbury Hill is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Are you structural engineers?
No. We’re roof surveyors, not structural engineers. If we see signs that need an engineer’s opinion, we will recommend one.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible.
Is a leaning chimney dangerous?
It’s worth having a leaning stack checked. Our survey notes how it looks and the condition of the bricks and joints, and if it may be a structural issue, we recommend a structural engineer.
Do you carry out surveys on Saturdays and Sundays?
We survey seven days a week: weekdays, Saturdays and Sundays. Tell us which days suit you when booking.
Chimney surveys in Sudbury Hill: local notes
The wider area around Sudbury Hill has a long history of building, with Northolt Manor about 2.2 miles west. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Whatever the covering, it is often the fixings, flashings, valleys and gutters that give out first.
Shop and office owners around London Designer Outlet may find that a written record of the roof’s condition helps you plan maintenance rather than react to leaks. If you live in an older home near Church of St Andrew, old fixings, lead flashings and tall chimneys are typical of older roofs.

What we look for on each type of roof
Flaunching
The sloping mortar around the pots is called flaunching. Once it cracks, water can get straight into the brickwork.
Chimney breasts and the loft
Stains on timbers or brickwork around the stack can point to a leak. We record what we see with photographs.
