Chimney surveys for homes and businesses in Thornhill
A damp patch on a chimney breast does not always come from the same place. Water may be getting in at the top through cracked flaunching or an uncapped pot, through the brickwork, or at the flashings. Condensation inside an unventilated stack is another common cause. Our survey checks each of these and records the likely cause. That points the work in the right direction. Common reasons to book are flashings pulling away from the stack and unused flues sealed without airflow, on chimney pots and cowls, chimney breasts and flaunching.
Around Thornhill, older cottages sit alongside bungalows and newer houses. Coverings range from slate and clay tiles on older homes to concrete tiles on many later ones. On older homes, chimney stacks, valleys and gutters are typically where the work is. The fixings under an older roof frequently fail before good slates or tiles do.
We write the report in plain English, so it makes sense without any roofing background. Photos show what each point refers to.

Why it’s worth a survey now in Thornhill
A loose pot or brick can fall from height. A survey picks them out so they can be made safe by a suitable contractor. Around Thornhill, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
Our price is from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT, and we can help you choose.
What you get with us
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Packages from £150, inc. VAT
- A written report with photos
- Covered by professional indemnity and public liability insurance

Do you need a chimney survey in Thornhill?
Removing a chimney breast inside can leave questions about how the stack is supported. We note what’s visible in the loft space and outside, and the report recommends a structural engineer if support is a concern.
Signs worth acting on include:
- Damp on a chimney breast inside
- A stack that appears to lean
- Loose, cracked or missing pots
- Eroded joints in the brickwork
Homes near green spaces such as Westwood Woodland Park can get more leaves in their gutters in autumn.
Before booking any roof surveyor
- Their drone registration, if they fly one
- What insurance they carry
- What they will not be able to tell you
- Will they check the loft as well as the outside?
Before and after the survey
A survey works best with a little help from you, before and after. Some tips:
- Keep track of stains on chimney breasts
- Check that disused chimneys can still breathe
- Keep the report to compare against at the next survey
- Check fixings on the stack are secure
The report is emailed to you, ready to share with a roofer or builder. We use plain English and a photo for each defect so anyone reading it can see what we saw.
Keep an eye on chimney breasts for new damp patches. Early signs are easier to trace.
Can I check my roof myself?
What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Roofs, chimneys and gutters in Thornhill
Thornhill lies within about 3 miles of the sea, and places near the sea get more salt in the air and more wind than inland. Metal fixings and flashings corrode faster in salt air, while gales work at loose ridges, slates and tiles, while driving rain finds any gap. With South Stoneham House about 2.4 miles north-west, Thornhill sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a building such as Thornhill Primary School, large buildings have long gutter runs and big roofs that need checking like any other. If you run a business near Marlands Shopping Centre, knowing the roof’s condition lets you budget for work rather than pay for emergencies.

Thornhill questions
Can a landlord with a rental near Sholing station book a roof survey?
Yes, rented property is part of what we cover. You can phone 07833 053749 or drop us an email with the address and some details.
Will you come out to Thornhill?
Yes. Thornhill is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
How soon will I get the report?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.
Will you check the loft?
If there’s a loft and safe access to it, yes. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
Can you survey a chimney stack we share with next door?
Yes. Shared stacks are common on terraced and semi-detached houses. We record the stack as far as we can see it and flag anything on the neighbour’s side.
Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when you book.
What does a roof survey cost?
Prices start from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all with VAT included.
What happens on the day
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit normally takes about 1–2 hours for most homes, a little longer where there are several stacks. Some parts of a survey depend on the weather, so a visit to Thornhill is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from the ground and the loft can go ahead in most weather.

- We check every stack from wherever it can safely be seen.
- 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.
