Chimney surveys in Harrow Weald: local notes
About 0.9 miles south-west lies Headstone Manor, a reminder of how long the area around Harrow Weald has been built on. Older homes in the wider area often have features worth a closer look, like 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. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Whichever you have, the details that tend to fail before the covering itself get the closest look.
For businesses in and around places such as St. George's Shopping Centre, a written record of the roof’s condition helps you plan maintenance rather than react to leaks. If you look after a building like Salvatorian Roman Catholic College, large buildings have long gutter runs and big roofs that need checking like any other.

Chimney survey in Harrow Weald
Redundant chimneys are common, especially where fires have been replaced by central heating. A disused stack still needs looking after. Capping a stack without ventilation can trap moisture and lead to damp inside. Our survey looks at how each unused stack has been capped and checks the breasts for damp. You get photos of each stack and our recommendations. If you’re worried about worn or missing pointing and damp on a chimney breast inside, a survey will tell you what’s going on.
London has Victorian and Edwardian terraces in almost every borough, often with slate roofs, chimney stacks shared with neighbours and gutters hidden behind parapets. Slates can last a century or more, but the nails holding them corrode, and slates slip. In Harrow Weald, as across London, that’s why a roof needs a close look rather than a glance from the street. Shared chimney stacks and the lead around them are just as important to check.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

FAQs for Harrow Weald
I let a flat near Headstone Lane station. Can you check the roof?
Yes. We survey roofs for landlords, letting agents and managing agents as well as owners. You can ring 07833 053749 or email us with the address and what you need, and we will talk through which survey suits.
Will parking be an issue for a roof survey in Harrow Weald?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we’ll work around them.
Do you inspect the flue?
No. It is not a flue, sweep or gas safety inspection. We check the stack, pots, flaunching, pointing and flashings, and damp inside and flag anything that suggests the flue needs a look.
How long does the survey take?
Expect it to take an hour or two on an ordinary house, and about three to four hours for a commercial roof. The written report follows by email.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when booking.
What does a roof survey cost?
Prices start from £150, including VAT. We confirm the exact price before booking, and it depends on the roof’s size, access and the package you choose. To get a price, call 07833 053749 or use the contact form.
Do you use drones?
Where it’s applicable and safe, yes. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
What happens on the day
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes about one to two hours at most homes, though large, tall or awkward roofs take more time. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- We start by noting which stacks are in use, shared or causing concern.
- The flashings and the roof around each chimney are inspected.
- The top of each stack is checked for cracked flaunching and loose pots.
- Any lean, spalling or worn pointing is recorded.
- You receive a written report setting out what needs attention first.
How to prepare
- Let us know about parking near the property
- Have any questions written down, so nothing gets missed
- If it is not your property yet, arrange access through the agent
Getting a price
Unsure which package suits your roof? The easiest way is to ring 07833 053749 or send us an email and describe the roof and what’s worrying you. We’ll talk you through the options and what they cost.

What happens if roof problems are left?
Cracked flaunching and worn pointing are often modest repairs when they’re caught early. Leave it, and frost can work the stack loose, and the work grows. Any roof job in Harrow Weald means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Chimney survey starts from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT, and we can help you choose.

Common roof problems in Harrow Weald
The flaunching on top of a stack holds the pots in place and sheds water. Once it cracks, water gets in and frost makes the cracks bigger. In time, the pots can become loose.
These are some of the problems a survey can pick up:
- Damp on a chimney breast inside
- Pots or cowls that look unsafe
- Cracked or missing flaunching
- Mortar washing out of the joints

Roof by roof
Chimney breasts and the loft
Stains on timbers or brickwork around the stack can point to a leak. We record what we see with photos.
Chimney pots and cowls
For unused flues, we check whether caps or cowls allow ventilation. Poor capping can lead to damp inside the stack.
