Chimney survey in Codicote, Hertfordshire
A survey of chimney stacks, pots, flashings and flaunching for Codicote and the rest of Hertfordshire. We survey on any day of the week.
- Signs that a stack is leaning
- Damp patches on chimney breasts
- Disused chimneys trapping moisture
About our chimney survey in Codicote
If a chimney looks out of line, it is worth getting it checked. Stacks can lean when mortar on one side breaks down, frequently after years of flue gases and damp. We record the lean and the condition of the brickwork and pointing. If the stack looks like a structural issue, the report recommends a structural engineer. We survey brick chimney stacks, flaunching and chimney breasts, and people most frequently book us about unused flues sealed without airflow and a stack that appears to lean.
Houses in smaller places like Codicote can face open ground, where wind and driving rain hit the roof harder. That weather tells first on ridges, verges, chimneys and flashings. A proper look shows whether anything has started to loosen. Once one ridge tile or slate moves, wind gets under the next one too.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the chimney stack, the defects we found and what we recommend.

What we cannot see
Before booking, it is worth knowing what a survey will not do:
- Parts of the stack that can’t be seen safely or belong to a neighbour we cannot access
- Whether a stack needs rebuilding on structural grounds
- Gas safety checks, which need a Gas Safe registered engineer
If you’re not sure which survey you need, phone 07833 053749 or use the contact form and we’ll give you a straight answer before you book. What our survey covers.

Roof by roof
Flaunching
Flaunching takes the worst of the weather. The survey checks for cracking and gaps around each pot.
Rendered stacks
Some stacks are rendered, which can hide the condition of the brickwork beneath. The survey checks for cracking, bulging and staining in the render.
Your questions about chimney surveys in Codicote
Do you cover smaller places like Codicote?
Yes, Codicote is covered. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
Do you survey roofs for landlords with property near Knebworth station?
Yes, rented property is part of what we cover. You can ring 07833 053749 or send us an email with the address and a few details.
What should I do with a chimney I do not use?
A redundant chimney needs looking after like any other. Capping without airflow can lead to damp. We check how it is capped and its condition, so you can plan what to do with it.
Is a leaning chimney dangerous?
Don’t ignore it. Stacks can lean when mortar on one side breaks down. The survey records what we can see, and a structural engineer can assess whether it needs work.
What do I do with the report?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Can you give me structural calculations?
No. We note visible signs like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
What affects the cost of chimney surveys
Our packages start from £150, including VAT. The price for your roof depends on:
- Extra roofs, like extensions, dormers or garages
- Roof area
- The package you choose: Basic, Standard or Premium
- Building height and the viewpoints available
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.
Getting in touch
A little information up front helps. It helps to include:
- Pictures from the garden or a window, if you have them
- Anything about access we should know
- Your postcode, so we can check access and travel
- The style of property, from a terrace to a block
If you’re buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.
Local roofs in Codicote
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them. Shaw's Corner, about 1.7 miles south-west, is one of the historic houses in the wider area around Codicote. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you let a flat or house near Knebworth station, a roof report helps you deal with small faults before they turn into a call from a tenant. If you live in an older home near Parish Church of St Giles, the nails, lead and mortar on the roof may be wearing out even where the slates or tiles look fine.
Codicote is about 4 miles north-west of Welwyn Garden City, in Hertfordshire. In Codicote, as across Hertfordshire, every roof gets the same careful survey. Our Hertfordshire coverage includes Codicote. London is in our area too.

What happens on the day
We don’t take risks to get a closer look. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. Most visits take about 1–2 hours for most homes, a little longer where there are several stacks. In a smaller place like Codicote, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside.
- We go through the chimneys, any damp and any work done on them.
- We look at every stack from wherever it can be seen safely.
- We photograph and record the pots, flaunching, pointing and flashings.
- We look for damp on chimney breasts and in the loft space.
- The report, with photographs and recommendations, is emailed to you.
Preparing for the visit
- Unlock side gates and any roof access doors
- Show us where any leaks or stains appear
- Keep pets out of the way during the survey
How to book

Related advice
Why get it checked now?
If you are thinking of removing or reducing a stack, it helps to know its condition first. In a conservation area or on a listed building, changes may need permission from the council and the council can advise. Around Codicote, a leak in an older house can soak into timbers and plaster, which is far harder to put right than the roof fault itself.
Prices quoted always include VAT, and the report isn’t charged as an extra. Our price is from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

Signs you need a chimney survey in Codicote
Flashings seal the gap where a stack passes through the roof. With age they can lift, split or come away from the joints. When flashings fail, water often shows up in the loft or on the chimney breast. Lead is also a target for theft.
It is worth booking a survey if you’ve seen:
- A stack that appears to lean
- Spalled or crumbling bricks
- Gaps in the mortar around the pots
- Damp patches on chimney breasts
Anyone responsible for a site like Codicote Church of England Primary School will know that a written record of a large roof helps plan work for the holidays rather than in term time.
