Gosmore Chimney Survey
A careful look at the chimney stack at your property in Gosmore, and put it all in a photo-illustrated written report.
- Loose, cracked or missing pots
- Flashings pulling away from the stack
- Flaunching that has broken away
What we look for on each type of roof
Chimney breasts and the loft
Damp patches on chimney breasts often point to a problem above. We look at them and at the stack in the loft where there is safe access.
Chimney pots and cowls
Damaged pots are a safety concern as well as a leak risk. We record their condition with photos.
Chimney surveys for homes and businesses in Gosmore
Redundant chimneys are common, especially where fires have been replaced by central heating. Even when it isn’t used, a stack has to stay weathertight. Capping a stack without ventilation can trap moisture and lead to damp inside. Our survey looks at how each unused stack has been capped and checks the breasts for damp. You get photos of each stack and our recommendations. If you’ve noticed disused chimneys trapping moisture and signs that a stack is leaning, we can find out what’s behind it.
In a small place like Gosmore, many roofs stand in the open, which is hard on ridges, chimneys, flashings and gutters. Damp in old walls is slow to dry, so a small leak can do a lot of harm. A written report sets out what to deal with and in what order. Lead flashings and old chimney stacks are often where weather gets in first.
The written findings come 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.

Signs you need a chimney survey in Gosmore
Years of fires can affect the mortar inside a stack. Mortar can deteriorate unevenly from flue gases and moisture, which is one reason stacks start to lean.
Things that often lead to a survey include:
- Redundant stacks capped without ventilation
- Eroded joints in the brickwork
- Loose, cracked or missing pots
- Damp on a chimney breast inside
Trees in and around Butts Close shed leaves that can end up in nearby gutters, and blocked gutters overflow and soak walls.

Useful tips for Gosmore property owners
There is plenty you can do without going near the roof. What helps most:
- Check fixings on the stack are secure
- Check your stacks from the ground after strong winds
- Use a Gas Safe registered engineer for gas appliances
- Make sure unused flues are capped with ventilation
Many people use the report to get quotes for the work. With the same list in front of each contractor, comparing quotes is simpler.
Look at your chimneys from ground level now and then, especially after strong winds. Binoculars help you spot loose pots, missing mortar or lifted flashings.

What else we do in Gosmore
What happens on the day
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’s applicable and the weather allows. Most surveys take about one to two hours at a house, as part of a look at the roof around the stack. Older rural homes like those around Gosmore can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely, and anything we cannot see is noted.
- We start by noting which stacks are in use, shared or causing concern.
- We check the roof around each stack, including the flashings.
- We look at the flaunching and pots on every stack.
- We note the brickwork, pointing and any sign of leaning.
- You receive a written report setting out what needs attention first.
Getting ready for the survey
- Make a note of anything you’d like us to look at
- If you are buying, check with the agent that we can get in
- Point out any leaks or damp patches

Gosmore questions
Can a landlord with a rental near Hitchin station book a roof survey?
Yes, rented property is part of what we cover. Just ring 07833 053749 or email us and tell us about the building.
Will you come out to Gosmore?
Yes, Gosmore is covered. We work right across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
What do I do with the report?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you look in the roof space?
Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
What should I do with a chimney I do not use?
An unused stack still needs to stay weathertight and ventilated. Capping without airflow can lead to damp. Our survey records its condition and how it is capped, so you can plan what to do with it.
Gosmore homes and their roofs
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Whichever you have, the details that tend to fail before the covering itself get the closest look. Knebworth House, about 4.7 miles south-east, is one of the historic houses in the wider area around Gosmore. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years.
Landlords with a home close to Hitchin station may find that a dated record of the roof is useful when planning maintenance across a let. Anyone responsible for a site like St Ippolyts Church of England Aided Primary School will know that a written record of a large roof helps plan work for the holidays rather than in term time.
