Signs you need a chimney survey in Northaw Valley
Many chimneys are no longer used. A stack sealed without ventilation can trap damp. Damp patches can appear on chimney breasts even when nothing is leaking.
Look out for signs like these:
- Eroded joints in the brickwork
- Damp patches on chimney breasts
- Pots or cowls that look unsafe
- A stack that appears to lean
Shop and office owners around Spires Shopping Centre may find that a written record of the roof’s condition helps you plan maintenance rather than react to leaks.

Chimney survey in Northaw Valley
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. A survey finds these problems and records them with photos. We survey chimney breasts, chimney pots and cowls and shared and party-wall stacks, and people most often book us about gaps where the stack meets the roof and pots or cowls that look unsafe.
In a village or hamlet like Northaw Valley, older cottages and farmhouses frequently sit alongside barns, outbuildings and a few newer houses. Roofs there can be clay tile, slate, stone or thatch, and chimney stacks are often old. We report on whatever is safely visible, and thatch is a specialist material. On older roofs, it is typically the chimneys and lead flashings that need work first.
Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what isn’t.

FAQs for Northaw Valley
Will you come out to Northaw Valley?
Yes, Northaw Valley is covered. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Northaw Valley is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
What does a roof survey cost?
Prices start from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
Do you need to get into the loft?
Usually, if there’s one and it can be reached safely. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
Can you survey in bad weather?
Light rain does not typically stop a survey, and it can even help show where water is getting in. High wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions aren’t right we will arrange another day with you.
Which days do you carry out surveys?
Surveys run on weekdays and at weekends. To arrange a date, call 07833 053749 or email us.
How long is the visit?
Most surveys take about one to two hours for a house, while a commercial roof takes nearer three to four hours. We’ll confirm the timing when booking.
What a chimney survey does not cover
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Checks on boilers, fires or their flues
- Hidden sides of a shared stack
- A structural engineer’s assessment
If you are not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before you book. What a survey covers and does not.

Useful tips for Northaw Valley property owners
Over many surveys, some simple habits stand out:
- Use a Gas Safe registered engineer for gas appliances
- Check fixings on the stack are secure
- File photos of the stacks with your home records
- Look at the chimneys with binoculars after a storm
Once we’ve been, the findings are written up with photos. It covers the pots, flaunching, pointing, brickwork and flashings, and any damp we found inside. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Have worn pointing and cracked flaunching dealt with early. It’s far simpler than rebuilding a stack later.
What we look for on each type of roof
Brick stacks
Brick stacks rely on sound pointing to keep water out. We check the bricks for spalling and the joints for erosion.
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
Photographs are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. A typical visit takes about 1–2 hours for most homes, a little longer where there are several stacks. Older roofs in small places like Northaw Valley can have low, tight loft spaces, so it helps 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.
- Pots, cowls, flaunching, pointing and flashings are checked and photographed.
- We look for damp on chimney breasts and in the roof space.
- The report, with photographs and recommendations, is emailed to you.
How to prepare
- Move anything stored under the loft hatch
- Make a note of anything you’d like us to look at
- Make sure we can get to the back of the property
How to book
Booking is simple: just phone 07833 053749 or email us, let us know about the property and we will recommend the right survey. The price is agreed up front.
Advice
Local roofs in Northaw Valley
The wider area around Northaw Valley has a long history of building, with Wyllyotts Manor about 2.4 miles west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Each of these coverings has its own weak points, from fixings and valleys to flashings, chimneys and gutters.
If you own a rental within reach of Crews Hill station, a dated record of the roof is useful when planning maintenance across a let. The streets around a church like Parish Church of St Thomas A Becket are often among the oldest in a place, and if yours is one of the older homes nearby, old fixings, lead flashings and tall chimneys are typical of older roofs.
