Chimney survey in Tewin Wood
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 roof space. We record what we find with photos and recommendations. We survey chimney pots and cowls, flaunching and lead flashings, and people most frequently book us about mortar washing out of the joints and bricks with flaking faces.
Older buildings in small places like Tewin Wood may be listed or in a conservation area. If yours is, re-roofing in different materials may need consent, so the council is the place to check. A roof report helps you plan work with that in mind. Older materials like clay tiles, slate and stone are often matched when work is done.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Questions from Tewin Wood
Is Tewin Wood within the area you cover?
Yes, Tewin Wood is on our map. A small place gets exactly the same survey as a big one.
I let a flat near Welwyn North station. Can you check the roof?
Of course. We just need to know who will give access, and the report can go straight to you or your agent.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, let us know when you book.
Do you inspect shared chimneys?
Yes. We inspect whatever is safely visible and what you give us access to. If a defect seems to be on your neighbour’s side, the report records it and you can raise it with them.
Will I get photos?
Yes. Photos are taken throughout the survey, and they go into the written report.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions aren’t right, we will talk to you about another date.
How experienced are you?
More than 5,000 surveys over 20+ years.

How the survey works
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take about one to two hours at a house, as part of a look at the roof around the stack. Around Tewin Wood, older homes can have small or awkward roof spaces, so it’s useful to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- 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 loft space.
- The report, with photos and recommendations, is emailed to you.
Before we arrive
- Check pets are kept safely away
- Make sure we can get to the back of the property
- Leave a clear route to the loft

Tips that help
Here are a few things we’d tell any owner, before and after a survey:
- Check that disused chimneys can still breathe
- Have brackets on the chimney checked
- Use a Gas Safe registered engineer for gas appliances
- Keep the report to compare against at the next survey
After the visit, we write up the report with photos of each stack. It covers the pots, flaunching, pointing, brickwork and flashings, and any damp we found inside. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Watch for damp or staining on chimney breasts. The sooner damp is spotted, the easier the cause is to find.
Local roofs in Tewin Wood
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Whatever the covering, it’s often the fixings, flashings, valleys and gutters that give out first. The wider area around Tewin Wood has a long history of building, with Digswell House about 2.1 miles south-west. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
For businesses in and around places such as Howard Centre, a roof report helps plan work around trading rather than after a leak. If you look after a building such as Ridgeway Academy, long gutter runs and wide roofs on a building that size are worth checking on a regular cycle. Landlords with a home close to Welwyn North station may find that a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak.

Should I look at the roof myself first?
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
