Chimney survey in Thorley Street
A leaning chimney stack is worth having looked at. A stack may lean because the mortar on one side has weakened, which can happen over many years of use. The survey notes how the stack looks, how far it seems to lean and the state of the bricks and joints. Where it may be a structural concern, we will recommend a structural engineer. We are often asked to look into gaps where the stack meets the roof and pots or cowls that look unsafe, across shared and party-wall stacks, chimney pots and cowls and chimney breasts.
Older buildings in small places like Thorley Street may be 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. Older materials like clay tiles, slate and stone are frequently matched when work is done.
After the visit, you get a written report with photos, sent by email. It sets out the condition of the chimney stack, any defects and our written recommendations.

Chimney surveys in Thorley Street: local notes
About 3.6 miles west lies Much Hadham Palace, a reminder of how long the area around Thorley Street has been built on. 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. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them.
Take a building like Thorley Hill Primary School: long gutter runs and wide roofs on a building that size are worth checking on a regular cycle. For an older house near a landmark such as Parish Church of St James the Great, its chimney, valleys and lead work are likely to be the parts that need attention first.
Thorley Street is about 1 mile south of Bishop's Stortford, in Hertfordshire. We visit Thorley Street as part of our work across Hertfordshire, for homes and businesses alike. Across Hertfordshire, we cover Thorley Street and the places around it. You can also see our page for Chelmsford.

What happens on the day
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes between one and two hours on an ordinary house, and longer for a large or complex roof. Around Thorley Street, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We go through the chimneys, any damp and any work done on them.
- We check every stack from wherever it can safely be seen.
- We photograph and record the pots, flaunching, pointing and flashings.
- Inside, the chimney breasts and the loft are checked for damp where there’s access.
- You get a written report with photos and recommendations by email.
Preparing for the visit
- Have keys ready for side gates, garages or roof access doors
- For flats, make sure roof access has been agreed
- Have any paperwork from past roof work to hand

What affects the cost of chimney surveys
Prices always include VAT. The things that change the price are:
- How many separate roofs there are, such as extensions, dormers and garages
- How tall the building is and how easy the roof is to see
- Features like valleys, chimneys, dormers and parapets
- Any need for thermal images or a drone flight
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.
What we need to know
These details help when you contact us:
- Any photos you have, taken from the ground or a window
- The address and postcode of the property
- What’s prompted the survey
- Anything about access we should know
Getting a price is simple: just phone 07833 053749 or email us and give us some details about the property and we will point you to the right survey. The price is agreed up front.
Questions from Thorley Street
How do I find out if my home in Thorley Street is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you survey roofs for landlords with property near Bishops Stortford station?
Yes, landlords and letting agents book with us as well as owners. You can ring 07833 053749 or email us with the address and some details, including who will give access on the day.
Can you inspect my roof with a drone?
Yes, where it applies and safe. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Do you need to get into the loft?
Where it is relevant to the survey and there is safe access, yes. A clear path to the hatch helps.
How long is the visit?
That depends on the size and shape of the roof; most visits take between one and two hours on an ordinary house, while a commercial roof takes nearer three to four hours. The report is sent afterwards by email.
Do I have to be there for the survey?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Why is my chimney breast damp?
It can come from several places: water getting in at the top, through the brickwork or at the flashings, or moisture trapped in a stack with no ventilation. We check each one and note the most likely cause.
Surveys for landlords and agents in Thorley Street
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photographs included.
With a portfolio of properties, you can book surveys for several addresses. To arrange surveys for several addresses, call 07833 053749 or email us.
What we look for on each type of roof
Chimney pots and cowls
On redundant flues, we look at how the pots are capped. Capping without ventilation can trap moisture.
Flaunching
Flaunching is the mortar on top of a stack that holds the pots and sheds water. Cracks in it let water into the stack.
Common roof problems in Thorley Street
TV aerials, satellite dishes and their brackets are frequently fixed to chimneys. The extra load in wind can work bricks and joints loose. We check fixings on the stack as part of the survey.
These are some of the problems a survey can pick up:
- Pots or cowls that look unsafe
- Lifted or split lead flashings
- Damp on a chimney breast inside
- Worn or missing pointing
If you own a rental within reach of Bishops Stortford station, a dated record of the roof is useful when planning maintenance across a let.
Choosing a roof surveyor
- Whether VAT is in the quoted price
- How they plan to inspect the roof safely
- What follow-up you get after the report
- Whether they hold professional indemnity and public liability insurance
Why get it checked now?
If a stack seems to lean, don’t leave it. Our survey records it and says when a structural engineer should look at it, so you know where you stand. Where a roof is exposed, as many are in small places like Thorley Street, driving rain gets into any weakness, and damp in older walls is slow to dry out.
Prices start from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we can help you choose.
