Chimney survey in Holywell, Greater London
A survey of chimney stacks, pots, flashings and flaunching in Holywell, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Loose, cracked or missing pots
- Disused chimneys trapping moisture
- Cracked or missing flaunching
How a chimney survey works in Holywell
Our survey covers the structure of the stack and its weathering details. It is not a flue inspection, a chimney sweep or a gas safety inspection. For the flue itself, you will need a sweep or, for gas appliances, a Gas Safe registered engineer. If something we see points to the flue, we will say so. If you’re worried about loose, cracked or missing pots and staining on walls around the chimney, a survey will tell you what’s going on.
London has Victorian and Edwardian terraces in almost every borough, many with Welsh slate roofs, shared chimney stacks and parapet or valley gutters. Slates can last a century or more, but the nails holding them corrode, and slates slip. In Holywell, as across London, that’s why a roof needs a proper look rather than a glance from the street. Shared chimney stacks and the lead around them are just as important to check.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photograph. It records what’s sound as well as what isn’t.

Roof by roof
Flaunching
Flaunching is the mortar on top of a stack that holds the pots and sheds water. Once it cracks, water can get straight into the brickwork.
Rendered stacks
Cracked render can let water in and trap it behind. Cracks are photographed and noted.
Prices for chimney surveys in Holywell
When we price a survey, we consider:
- Features like valleys, chimneys, dormers and parapets
- The size of the roof
- House, block, shop or office
- Extra roofs, like extensions, dormers or garages
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. The roof’s size, height and access matter as well.
Booking your survey
What helps most when you contact us:
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
- Anything about access we should know
- Any stains, drips or damp patches you’ve seen indoors
Not sure which survey you need? It’s easiest to ring 07833 053749 or send us an email and describe the roof and what’s worrying you. We’ll explain the options and the price.
Do you need a chimney survey in Holywell?
Flashings seal the gap where a stack passes through the roof. They can lift in wind, crack with age or pull out of the mortar joints. When flashings fail, water often shows up in the loft or on the chimney breast. Lead is also a target for theft.
Most people get in touch when they’ve noticed something like this:
- Damp patches on chimney breasts
- Bricks with flaking faces
- Pots or cowls that look unsafe
- Disused chimneys trapping moisture
If you run a business near Charter Place, knowing the roof’s condition lets you budget for work rather than pay for emergencies.
Choosing a roof surveyor
- Whether you can ask questions once you have the report
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Whether VAT is added on top
- What’s outside the scope of the survey
Before and after the survey
You do not need to be a roofer to help. Here’s what helps most:
- Check your stacks from the ground after strong winds
- Use a Gas Safe registered engineer for gas appliances
- Make sure fixings on the stack are secure
- Keep the report to compare against at the next survey
You can send the report to roofers or builders for quotes. With the same list in front of each contractor, comparing quotes is simpler.
Watch for damp or staining on chimney breasts. Early signs are easier to trace.
Chimney surveys around Holywell
About 4.1 miles north lies High Elms Manor, a reminder of how long the area around Holywell has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Holywell is one of them, bay roofs, hips and later dormers each have their own details. Whichever you have, the details that tend to fail before the covering itself get the closest look.
The streets around a church such as St Oswald's Parish Church are often among the oldest in a place, and if yours is one of the older homes nearby, its roof may have old fixings, lead flashings and chimneys that need a closer look. If you live near a park such as King George V Playing Fields, or anywhere with mature trees, autumn leaves can block gutters and valleys.

What happens if roof problems are left?
Most people never get a proper look at their chimney stacks. Problems frequently go unnoticed until damp appears inside. A survey gives you a clear picture before that happens. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
Chimney survey starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we’ll tell you which fits.

What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, photograph what we find and make notes for the report. It usually takes about one to two hours at a house, as part of a look at the roof around the stack. London terraces rarely offer a view of the whole roof from one spot, so a visit in Holywell moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We start by noting which stacks are in use, shared or causing concern.
- The flashings and the roof around each chimney are inspected.
- We look at the flaunching and pots on every stack.
- We note the brickwork, pointing and any sign of leaning.
- The report explains the condition and which work is most urgent.
Before we arrive
- Jot down any questions you want answered
- For a flat or shared roof, check access with the freeholder or managing agent
- If you are buying, check with the agent that we can get in

Common questions in Holywell
I let a flat near Watford High Street station. Can you check the roof?
Yes, landlords and agents are among the people we work for. You can phone 07833 053749 or use the contact form with the address and what you need, and we will talk through which survey suits.
Does a conservation area affect roof work in Holywell?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How long will you be at the property?
It usually takes an hour or two at a typical home, and about three to four hours for a commercial roof. The report follows by email.
What if it rains on the day?
Light rain doesn’t typically stop a survey. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions aren’t right we’ll arrange another day with you.
Will you go up on the roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest.
What do I do with the report?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
What’s in the report?
A photo-illustrated written report, explaining the condition of the chimney stack, any defects and our recommendations, in order of urgency where relevant. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
