About our chimney survey in Blacknest
A leaning chimney stack is worth having looked at. Stacks can lean when mortar on one side breaks down, often after years of flue gases and damp. We record the lean and the condition of the brickwork and pointing. Where it may be a structural concern, we’ll recommend a structural engineer. If you are worried about signs that a stack is leaning and redundant stacks capped without ventilation, we can find out what’s behind it, whatever the roof.
In a village or hamlet like Blacknest, older cottages and farmhouses often sit alongside barns, outbuildings and a few newer houses. Roofs there can be clay tile, slate, stone or thatch, and chimney stacks are often old. Each needs checking in its own way, and thatch is a specialist material we report on as far as it can be seen. Chimneys and lead flashings on old roofs frequently need the most attention.
The report is written in plain words, so you do not need to be a roofer to follow it. Photographs show what each point refers to.

How it works
After the inspection, everything we found is written up as a report with photographs, sent to you by email. On timing, most surveys take an hour or two at a typical home, and about three to four hours for a commercial roof. Around Blacknest, older homes can have small or awkward roof spaces, so it is useful to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- First we talk through the stacks, their history and any problems.
- We check every stack from wherever it can be seen safely.
- We photograph and record the pots, flaunching, pointing and flashings.
- 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.
Preparing for the visit
- Have keys ready for side gates, garages or roof access doors
- Make a note of anything you’d like us to look at
- If it is not your property yet, arrange access through the agent

Why get it checked now?
If you’re thinking of removing or reducing a stack, it helps to know its condition first. Changes to stacks in conservation areas or on listed buildings may need consent, so check with them first. Where a roof is exposed, as many are in small places like Blacknest, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, which starts from £400, inc. VAT. We can help you choose the package that fits what you need to know.
What you get with us
- More than 5,000 surveys completed
- Satisfaction rate of 98%
- An independent look at the roof
- CAA-registered drone operator (Flyer ID and Operator ID)

How the survey changes by roof type
Chimney breasts and the loft
In the loft, staining around the stack often shows where water is getting in. We record what we see with photographs.
Flaunching
Flaunching is the mortar on top of a stack that holds the pots and sheds water. Once it cracks, water can get straight into the brickwork.
For landlords and managing agents
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays and at weekends, which can make access easier.
Letting agents and landlords in Blacknest book surveys as well as homeowners. A report with photographs gives you a clear record of the chimney stack, useful for planning maintenance.
Honest limits
Every survey has limits, and we’d rather be clear about that before you book. Keep these in mind:
- Structural calculations for a leaning stack
- The inside of the flue, which needs a sweep or flue specialist
- Hidden damage within the stack
If in doubt, ring 07833 053749 or email us and we’ll point you to the right survey before booking. The full list of what we check.

Signs you need a chimney survey in Blacknest
A stack takes the weather from every direction. Frost opens up cracks in the mortar, and rain gets into worn bricks and joints. People usually call us when they notice damp or a problem with the stack, or before a purchase.
Look out for signs like these:
- Eroded joints in the brickwork
- Cracked or missing flaunching
- Flashings pulling away from the stack
- Pots or cowls that look unsafe
Take a building like Holy Trinity CofE Primary School: its roofs, gutters and any chimneys need the same checks as a house’s, just on a bigger scale.
What to check before booking
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- How they plan to inspect the roof safely
- What follow-up you get after the report
- How long the report takes to arrive
Local roofs in Blacknest
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them. The wider area around Blacknest has a long history of building, with St Leonard's Hill about 4.2 miles north. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Sunningdale station may find that a roof report helps you deal with small faults before they turn into a call from a tenant. Living close to Silwood Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn.

Blacknest: your questions answered
Does a conservation area affect roof work in Blacknest?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you cover smaller places like Blacknest?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route when booking.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Can you inspect my roof with a drone?
Where it is applicable and safe, yes. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It is included in the Drone Roof Survey and, where it applies, the Premium Survey.
Is a leaning chimney dangerous?
A leaning stack should be looked at. Our survey notes how it looks and the condition of the bricks and joints, and recommend a structural engineer where it may be a structural concern.
Our stack is shared. Can you still survey it?
Yes. We inspect whatever is safely visible and what you give us access to. Where a problem appears to be on next door’s side, we note it and you can raise it with them.
