Chimney surveys for Welwyn Garden City homes and businesses

Chimney surveys in Welwyn Garden City: local notes

Historic houses such as Digswell House, about 1.5 miles north, show how far back building in the area around Welwyn Garden City goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Welwyn Garden City 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, and parts of a garden city may be in a conservation area, so check with the council before re-roofing.

Living close to Stanborough Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn. Take a building like Peartree Primary School: large buildings have long gutter runs and big roofs that need checking like any other. For an older house near a landmark like Church Of Saint Francis Of Assisi, its roof may have old fixings, lead flashings and chimneys that need a closer look.

About our chimney survey in Welwyn Garden City

If a chimney looks out of line, it’s worth getting it checked. A stack may lean because the mortar on one side has weakened, which can happen over many years of use. We record the lean and the condition of the brickwork and pointing. Where it may be a structural concern, we will recommend a structural engineer. We’re frequently asked to look into damaged chimney pots and cowls and a stack that appears to lean, on lead flashings, chimney pots and cowls and flaunching.

Around Welwyn Garden City, semis and terraces share chimneys, gutters and roof lines with the house next door. When a stack or gutter is shared, the problem may not be on your side alone. Shared parts are looked at as far as they can be seen safely from the property we’re surveying. It’s useful to mention any shared stacks or gutters when you book.

Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Honest limits

In fairness, a roof survey has limits:

  • A structural engineer’s assessment
  • Gas safety checks, which need a Gas Safe registered engineer
  • The inside of the flue, which needs a sweep or flue specialist

Welwyn Garden City questions

How do I find out if my home in Welwyn Garden City is listed?

Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.

Can a landlord with a rental near Welwyn Garden City station book a roof survey?

Yes, landlords and agents book with us as well as owners. You can ring 07833 053749 or drop us an email with the address and some details, including who will give access on the day.

Is this a RICS survey?

No. We check the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.

How can you see the top of the stack?

We use safe viewpoints rather than climbing onto the stack. Where it applies, our Premium Survey adds a drone inspection for a closer view. The report is clear about anything that couldn’t be seen.

Do you cover Welwyn Garden City for chimney surveys?

Yes. Our area covers London and South East England, and that includes Welwyn Garden City.

Which parts of the chimney do you look at?

We check the pots, cowls, flaunching, pointing, brickwork and flashings. We also check chimney breasts and the stack in the loft space where we can reach. You get a written report with photos.

What do I do with the report?

You receive the written report by email, with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.

What you can safely check yourself

Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.

Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.

Practical tips

Here are a few things we’d tell any owner:

  • Keep the report to compare against at the next survey
  • Photograph damp patches with the date
  • Ask about consent before removing a chimney on an older property
  • Glance at the stacks from the street now and then

If the stack is shared, you can pass the report to your neighbour. The photos show the problem and which side it’s on, as far as we could see.

Look at your chimneys from ground level now and then, particularly after strong winds. With binoculars, you can often see cracked flaunching or lifted lead.

What happens on the day

The visit normally starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. In total, it takes roughly 1–2 hours for most homes, a little longer where there are several stacks. In Welwyn Garden City, many roofs join a neighbour’s, so we check what can be seen of the shared parts from your side. It’s useful to know about previous repairs, leaks or recent work, so time on site goes where it is needed.

  1. First we talk through the stacks, their history and any problems.
  2. Each stack is inspected from safe positions outside.
  3. Pots, cowls, flaunching, pointing and flashings are checked and photographed.
  4. We look for damp on chimney breasts and in the loft space.
  5. The report, with photos and recommendations, is emailed to you.

Preparing for the visit

  • Make a note of anything you’d like us to look at
  • Mention any parking restrictions on your street
  • Agree roof access with the managing agent if it is shared
