Chimney survey in Letchworth, Hertfordshire
A survey of chimney stacks, pots, flashings and flaunching for Letchworth and the rest of Hertfordshire. Surveys run seven days a week.
- Spalled or crumbling bricks
- Gaps where the stack meets the roof
- Redundant stacks capped without ventilation
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
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 don’t climb up for a closer look.
Chimney survey in Letchworth
A damp patch on a chimney breast does not always come from the same place. It might come in at the top, through worn pointing or porous bricks, or where the flashings meet the roof. Moisture trapped inside a stack with no ventilation can also cause damp. Our survey checks each of these and records the likely cause. You then know where to start. We survey flaunching, chimney breasts and lead flashings, and common reasons people get in touch are bricks with flaking faces and unused flues sealed without airflow.
Most homes in a town like Letchworth are houses, so the roof is typically the owner’s to look after. Small faults, such as a cracked ridge, a slipped tile or a blocked gutter, are cheaper to deal with early. A roof report gives you a list of what needs doing and how soon. The photos let you see the parts of the roof you can’t get to.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Why act early in Letchworth
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. Extensions and dormers on homes around Letchworth often hide the first signs of trouble at their joints with the main roof. A few wet winters later, it can mean new plaster and decorating as well as roof work.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.

The survey, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes about 1–2 hours for a house, while a commercial roof takes nearer three to four hours. A typical visit in Letchworth begins with the street side of the roof and then moves round the building. The back garden is frequently where extensions, dormers and rear slopes are best seen, so unlocked gates help. The loft comes next, where there is safe access.
- We go through the chimneys, any damp and any work done on them.
- We check every stack from wherever it can be seen safely.
- We photograph and record the pots, flaunching, pointing and flashings.
- Inside, the chimney breasts and the loft are checked for damp where there’s access.
- The report, with photos and recommendations, is emailed to you.
Before we arrive
- Tell us where we can park nearby
- Let us know about any leaks, stains or damp patches you know of
- Have any questions written down, so nothing gets missed

Local roofs in Letchworth
Letchworth is one of England’s garden cities, planned in the early twentieth century. The original garden city houses are now more than a century old, alongside later estates. Older roofs may still have their original coverings, with fixings and underlay that have done a long stint. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. On roofs like these, good slates or tiles can outlast the nails, battens, lead and mortar around them.
If you let a flat or house near Letchworth Garden City station, the gap between tenancies is a good time to have the roof looked at. The streets around a church such as Church of St Paul are often among the oldest in a place, and if your house is among the older ones nearby, corroded nails, tired lead and weathered chimney pointing are the things to watch on older roofs.
Letchworth is about 5 miles north of Stevenage, in Hertfordshire. Whether the building in Letchworth is a house, a flat or a commercial unit, the roof can be surveyed. Our area takes in places right across Hertfordshire, large and small. You can also see our page for Milton Keynes.

Common questions in Letchworth
How do I find out if my home in Letchworth is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you cover Letchworth?
We do. Every survey there gets the same written report with photos.
Will I get photos?
Yes. Photographs are part of every report.
How long have you been surveying roofs?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
My chimney looks like it is leaning. What should I do?
It is worth having a leaning stack checked. Our survey notes how it looks and the condition of the bricks and joints, and recommend a structural engineer where it may be a structural concern.
Can you survey in bad weather?
It depends on the weather and the survey. In strong wind or heavy rain, a drone cannot fly and access may not be safe, so we’d move the date with you.
What’s in the report?
A written report with photos, covering the condition of the chimney stack, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
When to book a survey in Letchworth
Stacks that were used for open fires for many years can weaken from the inside. Flue gases and damp can break down the mortar, sometimes more on one side than the other, which can make a stack lean.
These are some of the problems a survey can pick up:
- Flaunching that has broken away
- Mortar washing out of the joints
- Damp on a chimney breast inside
- Signs that a stack is leaning
Hinxworth Place, about 4.5 miles north, is one of the historic houses in the wider area around Letchworth. If your home is one of the older ones, the roof may have been repaired many times, and the survey records how each part is holding up.
What to check before booking
- What experience they bring
- What the survey won’t cover
- What insurance they carry
- Whether any drone flown is registered with the CAA
