Chimney survey in Walsworth: what you get
Chimney stacks take more weather than almost any other part of a house. In time, flaunching cracks, mortar washes out and flashings come loose. That lets water into the brickwork, which can show up as damp on a chimney breast or in the loft space. A survey finds these problems and records them with photographs. Typical surveys look at a chimney out of line and redundant stacks capped without ventilation, across brick chimney stacks, flaunching and chimney pots and cowls.
In a smaller place like Walsworth, homes range from older cottages to bungalows and newer houses. Older roofs can have slate, clay tiles or other traditional coverings, while many later ones have concrete tiles. On older homes, chimney stacks, valleys and gutters are typically where the work is, and the fixings under the coverings matter too. Nails and battens under older coverings often give out before the slates or tiles themselves.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Why get it checked now?
Before deciding what to do with a redundant stack, a survey shows how it is doing. Changes to stacks in conservation areas or on listed buildings may need consent and the council can advise. Arranging work in a smaller place like Walsworth is easier with notice than in an emergency. Knowing early gives you time to get the right people in.
A Basic Survey starts from £150, including VAT. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the exact price before booking.

Take a look at what a roof survey costs and two real surveys.
How the survey changes by roof type
Chimney pots and cowls
A loose or cracked pot can fall from height. We photograph each pot and note any damage.
Rendered stacks
A rendered stack can mask problems in the bricks below. We look for cracks, hollow areas and staining.
Checking the roof from the ground
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Signs you need a chimney survey in Walsworth
Where a chimney meets the roof, lead flashings keep water out. With age they can lift, split or come away from the joints. When flashings fail, water frequently shows up in the loft or on the chimney breast. Lead is also a target for theft.
A survey makes sense if you’ve noticed:
- Bricks with flaking faces
- Redundant stacks capped without ventilation
- Staining on walls around the chimney
- Eroded joints in the brickwork
If you own a rental within reach of Hitchin station, a dated record of the roof is useful when planning maintenance across a let.
What to check before booking
- Their drone registration, if they fly one
- Which viewpoints they use to see the roof
- What follow-up you get after the report
- What insurance they carry
Common questions in Walsworth
I let a flat near Hitchin station. Can you check the roof?
Yes, landlords and letting agents book with us as well as owners. Just call 07833 053749 or use the contact form and tell us about the building, including who will give access on the day.
Do you cover smaller places like Walsworth?
Yes, Walsworth is covered. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned beforehand.
What should I do with a chimney I don’t use?
There’s no single answer. The survey shows its condition and how it’s been capped. In a conservation area or on a listed building, changes may need consent.
How do I book a survey in Walsworth?
To arrange a survey, call 07833 053749 or drop us an email and let us know the address and what you’d like to know. We’ll confirm the price and agree a day with you.
Can you find out why my chimney breast is damp?
It can come from several places: cracked flaunching, worn pointing, failed flashings, uncapped pots, or damp trapped in an unventilated stack. We look at each one and note the most likely cause.
Do you take photos of the roof?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Chimney surveys in Walsworth: local notes
Older houses in the South East frequently 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. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
Trees in and around Butts Close shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching. Take an older house close to St Faith's Church: old fixings, lead flashings and tall chimneys are typical of older roofs.

What happens on the day

As for time on site, most surveys take between one and two hours at a house, as part of a look at the roof around the stack. In a smaller place like Walsworth, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- We start with the details: how many stacks, whether any are shared and any signs of damp.
- We inspect each stack from safe viewpoints outside.
- The pots, cowls, flaunching, pointing, brickwork and flashings are checked and photographed.
- Where there is safe access, we look at the stack in the loft and the chimney breasts for damp.
- You get a written report with photographs and our recommendations.
How to prepare
- Gather any invoices or paperwork from past roof work
- If you are buying, check with the agent that we can get in
- For a flat or shared roof, check access with whoever owns or manages the building
