Questions from Tonwell
Is Tonwell within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Can a landlord with a rental near Ware station book a roof survey?
Yes, rented property is part of what we cover. Just call 07833 053749 or use the contact form and let us know about the building, including who will give access on the day.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
How can you see the top of the stack?
We use safe viewpoints rather than climbing onto the stack. Where applicable, our Premium Survey adds a drone inspection for a closer view. The report is clear about anything that couldn’t be seen.
Which parts of the chimney do you look at?
The whole stack, as far as it can be seen safely: pots, cowls, flaunching, pointing, bricks and flashings. Leaning, unused stacks and damp on chimney breasts are recorded too.
Do you climb onto every roof?
Not unless it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
How fast do I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when booking.
Chimney surveys for homes and businesses in Tonwell
Redundant chimneys are common, especially where fires have been replaced by central heating. Even when it is not used, a stack has to stay weathertight. 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. The report sets out what we found and what we recommend. If you’re worried about damp patches on chimney breasts and damaged chimney pots and cowls, we can find out what’s behind it, on lead flashings, chimney pots and cowls and chimney breasts alike.
In a small place like Tonwell, many roofs stand in the open, so ridges, chimney stacks, flashings and gutters work hard. Damp in old walls is slow to dry, so a small leak can do a lot of harm. A roof report shows what needs attention first. On exposed older roofs, chimneys and lead flashings are frequently the first to give way.
You receive the findings by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Why get it checked now?
A damp chimney breast seldom dries out until the cause is found. It can stain walls and damage plaster. Finding the cause means the right work can be planned. Older cottages and farmhouses around Tonwell can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Chimney survey starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

What we are asked to look at in Tonwell
TV aerials, satellite dishes and their brackets are often fixed to chimneys. The extra load in wind can work bricks and joints loose. Any fixings on the stack are checked and recorded.
Signs worth acting on include:
- Disused chimneys trapping moisture
- Damp on a chimney breast inside
- Worn or missing pointing
- Spalled or crumbling bricks
Anyone responsible for a site like Tonwell St Mary's Church of England Primary School will know that long gutter runs and wide roofs on a building that size are worth checking on a regular cycle.

Chimney surveys in Tonwell: local notes
Historic houses such as Aston Bury, about 4.6 miles north-west, show how far back building in the area around Tonwell goes. 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 a listed home or one in a conservation area may need consent for changes of material. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Whichever you have, the details that tend to fail before the covering itself get the closest look.
If you let a flat or house near Ware station, a roof report helps you deal with small faults before they turn into a call from a tenant.

The survey, step by step

- We check every stack from wherever it can safely be seen.
- Pots, cowls, flaunching, pointing and flashings are checked and photographed.
