Osterley Chimney Survey
We carry out chimney surveys in Osterley and the rest of Greater London. We survey on weekdays and at weekends.
- Lifted or split lead flashings
- A chimney out of line
- Loose, cracked or missing pots
Tips that help
Getting the most from a chimney survey starts before we arrive and carries on afterwards. Some tips:
- Note any damp on chimney breasts and when it appears
- Find out whether changes to a stack need permission
- Look at the chimneys with binoculars after a storm
- Check that disused chimneys can still breathe
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.
Unused stacks should be capped in a way that still lets air through. Ventilation helps keep the stack dry.
About our chimney survey in Osterley
Many homes have chimneys that are no longer used. A disused stack still needs looking after. If it has been capped without ventilation, damp can build up inside it. We check how redundant stacks have been capped and look for damp in the chimney breasts. You get photos of each stack and our recommendations. Typical surveys look at disused chimneys trapping moisture and damp patches on chimney breasts, on shared and party-wall stacks, flaunching and brick chimney stacks.
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, in Osterley 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.
Findings are set out part by part, from the coverings down to the gutters. You’ll see the good as well as the bad.

Honest limits
Before you book, it’s worth knowing what a survey will not do:
- Whether the flue is safe to use
- Structural calculations for a leaning stack
- What’s inside the brickwork or behind render, without opening up
Not sure which survey suits your roof? You can call 07833 053749 or email us and we’ll tell you before booking. The full list of what we check.
Roof types and parts we check
- Brick chimney stacks
- Lead flashings
- Flaunching
- Shared and party-wall stacks
- Chimney pots and cowls
- Chimney breasts
Why get it checked now?
Damp in a chimney breast normally gets worse while the cause is left. It can spoil decoration and plaster. Knowing whether it’s the flaunching, flashings, brickwork or ventilation means the right fix can be planned. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.

Local roofs in Osterley
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Osterley is one of them, bay roofs, hips and later dormers each have their own details. Whichever you have, the details that tend to fail before the covering itself get the closest look. Osterley House, about 0.3 miles north, is one of the historic houses in the wider area around Osterley. 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.
Take a building like Isleworth and Syon School for Boys: large buildings have long gutter runs and big roofs that need checking like any other. If you let a flat or house near Isleworth station, a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak.
Osterley is about 1 mile north of Hounslow, in Greater London. Surveys in Osterley work the same way as everywhere we cover: a careful look at what can safely be seen, photographs and a clear written report.

What we do, step by step
Every roof is different, but as a rough guide the survey takes about one to two hours at a house, as part of a look at the roof around the stack. If you have questions on the day, just ask. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Osterley runs like any other.
- First we talk through the stacks, their history and any problems.
- We look at every stack from wherever it can be seen safely.
- Pots, cowls, flaunching, pointing and flashings are checked and photographed.
- Inside, the chimney breasts and the loft are checked for damp where there’s access.
- You get a written report with photos and recommendations by email.
Getting ready for the survey
- Keep pets out of the way during the survey
- Let us know about any leaks, stains or damp patches you know of
- Leave side gates unlocked

Advice
What a survey costs
Survey packages start from £150, with VAT included. The price for your roof depends on:
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
- Whether it is a home or a commercial building
- Building height and the viewpoints available
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you want to find out.
Booking your survey
Getting the details right at the start saves time. Please include:
- The reason for the survey, such as buying, a leak or storm damage
- Anything about access we should know
- Where water is showing inside, if it is
- What kind of property and roof it is
Most bookings start with a short call: ring 07833 053749 or use the contact form. The price is agreed before a date is set.
When to book a survey in Osterley
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.
These are some of the problems a survey can pick up:
- Disused chimneys trapping moisture
- Damp patches on chimney breasts
- Flaunching that has broken away
- Flashings pulling away from the stack
Shop and office owners around Treaty Centre may find that a dated report on the roof is useful for planning and for any lease discussions.

FAQs for Osterley
Can a landlord with a rental near Isleworth station book a roof survey?
Of course. We just need to know who will give access, and we can send the report to you or your agent.
Does a conservation area affect roof work in Osterley?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Is a chimney survey the same as a flue inspection?
No. A flue inspection, sweep or gas safety check is a separate job. We check the stack, pots, flaunching, pointing and flashings, and damp inside and flag anything that suggests the flue needs a look.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Do you inspect shared chimneys?
Yes. Many houses share stacks with a neighbour. We survey what we can see safely, and note anything that seems to involve next door.
Should I worry about a leaning stack?
It is 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 look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps.
