Useful tips for Gustard Wood property owners
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Look at the chimneys with binoculars after a storm
- Find out whether changes to a stack need permission
- Keep the report to compare against at the next survey
- Note any damp on chimney breasts and when it appears
If the stack is shared, you can pass the report to your neighbour. The photos show the problem and which side it is on, as far as we could see.
Get small mortar repairs done while they’re small. Small repairs now can save bigger work later.
About our chimney survey in Gustard Wood
On terraced and semi-detached houses, a chimney stack is often shared with next door. We check whatever is safely visible and what the owner gives us access to. Where a problem seems to involve a neighbour’s side, the report records it and you can then discuss it with them. Everything is written up with photos and what we recommend. Typical surveys look at loose, cracked or missing pots and bricks with flaking faces, on chimney breasts, shared and party-wall stacks and flaunching.
In a small place like Gustard Wood, many roofs stand in the open, which is hard on ridges, chimneys, flashings and gutters. Damp in old walls is slow to dry, so a small leak can do a lot of harm. A written report sets out what to deal with and in what order. On exposed older roofs, chimneys and lead flashings are often the first to give way.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

Different roofs, different checks
Chimney breasts and the loft
Where a breast has been taken out, we check what supports the stack. A structural engineer should confirm whether it’s adequate.
Lead flashings
Over time, lead can lift or come away from the brickwork. Any loose or split flashings are recorded.
What we do, step by step
Once we have finished looking, we write up our findings as a report with photos. On timing, it usually takes roughly 1–2 hours for most homes, a little longer where there are several stacks. For a village or hamlet like Gustard Wood, the journey is planned in advance: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- First we talk through the stacks, their history and any problems.
- Each stack is inspected from safe positions outside.
- We photograph and record the pots, flaunching, pointing and flashings.
- We look for damp on chimney breasts and in the roof space.
- You get a written report with photos and recommendations by email.

- If you are buying, check with the agent that we can get in

Advice
Common roof problems in Gustard Wood
Some owners book because a chimney breast has been removed below and they want to know about the stack above. We record what we can see in the loft and outside, and recommend a structural engineer where support is in question.
A survey makes sense if you’ve noticed:
- Worn or missing pointing
- Lifted or split lead flashings
- Damp patches on chimney breasts
- Unused flues sealed without airflow
For landlords with property near Harpenden station, a roof report helps you deal with small faults before they turn into a call from a tenant.
Questions to ask before you book
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- What exactly goes into their report
- Their insurance cover
- Which limits apply to the survey
Gustard Wood questions
Is Gustard Wood within the area you cover?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Does a conservation area affect roof work in Gustard Wood?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
How do I arrange a chimney survey in Gustard Wood?
Just ring 07833 053749 or send us an email with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
Will you check the chimney is safe to use with a fire?
No. We survey the stack and its weathering, not the flue. For the flue, you’ll need a sweep or, for gas, a Gas Safe registered engineer.
How long will you be at the property?
Expect it to take an hour or two for most homes, a little longer where there are several stacks. You will then get the report by email.
Will I get photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
Checking the roof from ground level
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Local roofs in Gustard Wood
Historic houses such as Shaw's Corner, about 1.2 miles north-east, show how far back building in the area around Gustard Wood goes. 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. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Whichever you have, the details that tend to fail before the covering itself get the closest look.
Take an older house close to St Peter: the nails, lead and mortar on the roof may be wearing out even where the slates or tiles look fine. Take a building like St Helen's Church of England Primary School: its roofs, gutters and any chimneys need the same checks as a house’s, just on a bigger scale.
