About our chimney survey in Allen's Green
If a chimney looks out of line, it’s worth getting it checked. Stacks can lean when mortar on one side breaks down, often after years of flue gases and damp. We record the lean and the condition of the brickwork and pointing. Where it may be a structural concern, we will recommend a structural engineer. Common reasons to book are cracked or missing flaunching and mortar washing out of the joints, across brick chimney stacks, shared and party-wall stacks and chimney breasts.
Somewhere as small as Allen's Green, homes are frequently older cottages and farmhouses, with outbuildings and some newer houses. Older roofs may be clay tile, slate, stone or thatch, often with chimneys that have stood a long time. Each needs checking in its own way, and thatch is a specialist material we report on as far as it can be seen. Chimneys and lead flashings on old roofs frequently need the most attention.
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.

How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take roughly 1–2 hours at a house, as part of a look at the roof around the stack. Rural addresses near Allen's Green can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- 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.
- Any lean, spalling or worn pointing is recorded.
- The report explains the condition and which work is most urgent.
How to prepare
- Have any paperwork from past roof work to hand
- Clear the way to the loft hatch
- Jot down any questions you want answered
Booking a survey
Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, so phone 07833 053749 or email us with the details.

Chimney surveys in Allen's Green: local notes
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. Knowing the covering helps explain which parts of a roof are likely to need work first. Much Hadham Palace, about 2.2 miles north-west, is one of the historic houses in the wider area around Allen's Green. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If you own a rental within reach of Sawbridgeworth station, the gap between tenancies is a good time to have the roof looked at. For an older house near a landmark such as Former Church of St Anne, the nails, lead and mortar on the roof may be wearing out even where the slates or tiles look fine.
Allen's Green is about 3 miles south-west of Bishop's Stortford, in Hertfordshire. Whether the building in Allen's Green is a house, a flat or a commercial unit, we can survey the roof on a weekday or at the weekend. Our Hertfordshire coverage includes Allen's Green and the places around it. For surveys nearby, see our Chelmsford page.

Roof by roof
Chimney pots and cowls
On redundant flues, we check how the pots are capped. Capping without ventilation can trap moisture.
Chimney breasts and the loft
Stains on timbers or brickwork around the stack can point to a leak. What we find is photographed and described.
Prices for chimney surveys in Allen's Green
A few things affect what a survey costs:
- How big the roof is
- Extensions, dormers and garages with roofs of their own
- Commercial roofs and larger buildings
- The package you choose: Basic, Standard or Premium
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £150, including VAT.

Common questions in Allen's Green
Is Allen's Green within the area you cover?
Yes, Allen's Green is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is my home in Allen's Green listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Will you check the loft?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch.
What will the report tell me?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
Do you need to go on the roof to check the chimney?
Each stack is viewed from the safest viewpoints: the ground, nearby windows and higher points, and the loft space. A drone inspection is included in our Premium Survey where it applies. If part of a stack cannot be seen, the report says so.
How much does a chimney survey cost in Allen's Green?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, and it is agreed before booking.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we will talk to you about another date.
What this survey cannot tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Flue inspections or sweeping
- Gas safety checks, which need a Gas Safe registered engineer
- Areas we cannot view from safe positions
Not sure which survey suits your roof? You can call 07833 053749 or use the contact form and we’ll tell you before you book. What a survey covers and doesn’t.
What we check
- Brick chimney stacks
- Shared and party-wall stacks
- Lead flashings
- Chimney breasts
- Flaunching
- Chimney pots and cowls
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
