Chimney survey in Patchetts Green: what you get
A chimney survey is about the outside of the stack and the roof around it. It is not a flue inspection, a chimney sweep or a gas safety inspection. If you use a fire or a gas appliance, the flue should be checked by a sweep or a Gas Safe registered engineer as appropriate. If something we see points to the flue, we will say so. We survey chimney pots and cowls, shared and party-wall stacks and flaunching, and people most frequently book us about gaps where the stack meets the roof and spalled or crumbling bricks.
In a village or hamlet like Patchetts Green, older cottages and farmhouses frequently sit alongside barns, outbuildings and a few newer houses. Older roofs may be clay tile, slate, stone or thatch, often with chimneys that have stood a long time. We report on what can be seen safely, and thatch is a specialist material. On older roofs, it is typically the chimneys and lead flashings that need work first.
Nothing in the report is left vague: where something needs attention, it says so plainly.

What a survey costs
Prices always include VAT. What changes the price is:
- Whether thermal imaging or a drone is needed
- The number of roofs, including extensions and garages
- The package you choose: Basic, Standard or Premium
- The height of the building and how the roof can be seen safely
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We will give you the figure before anything is booked.
What we need to know
To price your survey accurately, we’ll ask about:
- Where the property is, with the postcode
- Pictures from the garden or a window, if you have them
- The type of building and roof, such as pitched or flat
- Why you want a survey: buying, a leak, a storm or new work
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or email us when you’re ready.
Patchetts Green homes and their roofs
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. Whichever you have, the details that tend to fail before the covering itself get the closest look. Historic houses like High Elms Manor, about 3 miles north-west, show how far back building in the area around Patchetts Green goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Take an older house close to Church of St John the Baptist: its chimney, valleys and lead work are likely to be the parts that need attention first. If you own a rental within reach of Watford North station, knowing the condition of the roof, chimneys and gutters helps you plan work rather than react to complaints. For businesses in and around places such as Harlequin Centre, a written record of the roof’s condition helps you plan maintenance rather than react to leaks.

Why act early in Patchetts Green
Cracked flaunching and worn pointing are often modest repairs when they’re caught early. Left for a few winters, frost and water can loosen pots and bricks and the job gets bigger. Older cottages and farmhouses around Patchetts Green can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Our price is from £150, including VAT.

Patchetts Green questions
Does a conservation area affect roof work in Patchetts Green?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Will you come out to Patchetts Green?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will you walk on the roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where it applies.
Do you need to go on the roof to check the chimney?
Each stack is viewed from the safest viewpoints: from ground level, windows and vantage points, and from the loft where there’s access. Our Premium Survey includes a drone inspection where it applies. If part of a stack cannot be seen, the report says so.
Do you look in the loft space?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement.
What causes damp on a chimney breast?
Damp on a chimney breast usually means water is getting into the stack, or moisture is trapped inside it. The survey looks at the stack, the flashings and the capping and records the likely cause.
Do you inspect the flue?
No. It isn’t a flue, sweep or gas safety inspection. We check the structure and weathering of the stack and any damp and flag anything that suggests the flue needs a look.

How it works
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. Most visits take about 1–2 hours for a house, though large, tall or awkward roofs take more time. In a small place like Patchetts Green, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- 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
- Let us know about any leaks, stains or damp patches you know of
- Jot down any questions you want answered
- Clear the way to the loft hatch

What we look for on each type of roof

Chimney pots and cowls
A loose or cracked pot can fall from height. We photograph each pot and note any damage.
