Chimney surveys for homes and businesses in Grendon Underwood
A chimney survey is about the outside of the stack and the roof around it. It is not a flue inspection, a sweep or a gas safety check. For the flue itself, you will need a sweep or, for gas appliances, a Gas Safe registered engineer. We will tell you if we see anything that suggests they should take a look. If you’ve noticed gaps where the stack meets the roof and redundant stacks capped without ventilation, we can find out what’s behind it, on brick chimney stacks, lead flashings and chimney pots and cowls alike.
Some older homes in villages like Grendon Underwood are listed or in a conservation area. If yours is, re-roofing in different materials may need consent, so the council is the place to check. A roof report helps you plan work with that in mind. Where a building is listed, matching the existing roof materials is often expected.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Why it’s worth a survey now in Grendon Underwood
Chimneys are easy to forget because you rarely see the top of them. Problems often go unnoticed until damp appears inside. Surveying the stack now can catch problems first. Around Grendon Underwood, older homes often have old roof timbers, and water through a failed covering can rot timber if it’s left.
Chimney survey starts from £150, including VAT. The final price depends on the size and height of the roof, access and the package you choose.

Take a look at what a roof survey costs and two real surveys.
How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take about 1–2 hours for a house, though large, tall or awkward roofs take more time. In a hamlet or village like Grendon Underwood, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- First we talk through the stacks, their history and any problems.
- Each stack is inspected from safe positions outside.
- 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.
- The report, with photographs and recommendations, is emailed to you.
Before the survey
- Make a note of anything you’d like us to look at
- Check pets are kept safely away
- Gather any invoices or paperwork from past roof work
Getting a price
Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can call 07833 053749 or email us to find out.

DIY checks: what’s safe
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Grendon Underwood: your questions answered
Is Grendon Underwood within the area you cover?
Yes, Grendon Underwood is covered. We work right across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Does a conservation area affect roof work in Grendon Underwood?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
What does a chimney survey cover?
The whole stack, as far as it can safely be seen: pots, cowls, flaunching, pointing, bricks and flashings. Leaning, unused stacks and damp on chimney breasts are recorded too.
How do I arrange a chimney survey in Grendon Underwood?
The quickest way is to call 07833 053749 or send us an email. Give us the address and some details about the roof, and we will point you to the right survey. Surveys run on any day of the week.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
How can you see the top of the stack?
We use safe viewpoints rather than climbing onto the stack. A drone inspection is part of the Premium Survey where it applies. Any area we couldn’t view is noted.
Our stack is shared. Can you still survey it?
Yes. Many houses share stacks with a neighbour. We survey what we can see safely, and note anything that seems to involve next door.
What this survey can’t tell you
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Hidden damage within the stack
- Whether a stack needs rebuilding on structural grounds
- Gas safety checks, which need a Gas Safe registered engineer
If you are not sure which survey you need, phone 07833 053749 or email us and we’ll give you a straight answer before you book. The full list of what we check.

Local roofs in Grendon Underwood
Thatch survives on some older buildings in Buckinghamshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Whatever the covering, it’s often the fixings, flashings, valleys and gutters that give out first. Historic houses like Claydon House, about 3.6 miles north-east, show how far back building in the area around Grendon Underwood goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Anyone responsible for a site like Grendon Underwood Combined School will know that large buildings have long gutter runs and big roofs that need checking like any other. Take an older house close to Church of St Leonard: its roof may have old fixings, lead flashings and chimneys that need a closer look.

Tips from our surveys
These tips come from what we see on roofs every week, before and after a survey:
- Make sure fixings on the stack are secure
- Use a Gas Safe registered engineer for gas appliances
- Check your stacks from ground level after strong winds
- Ask for ventilated caps on redundant stacks
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.
Make sure fixings on the stack are sound, and moved if they’re working it loose. Less load on the stack means less strain in wind.
