FAQs for Holwell
Will you come out to Holwell?
Yes, Holwell is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is my home in Holwell listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Can a leak be traced on a dry day?
In many cases, yes. Leaks leave clues, such as staining, damp timber and moisture in materials. Intermittent leaks can be harder, so photos and notes from when it leaks help a lot.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
How much does a roof leak investigation cost in Holwell?
Roof leak investigation starts from £150, including VAT. We confirm the price for your roof before you book. For a price, call 07833 053749 or use the contact form.
Can you always find the source?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but intermittent leaks that need particular weather can be harder. The report sets out what we found and the most likely routes.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Roof leak investigation in Holwell
Some ‘leaks’ are not leaks at all. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, and the stains look much like a leak. Telling the two apart matters, since the cure for one will not solve the other. The pattern of the damp, the ventilation and the timing all help us decide. We survey lead flashings, flat roof details and rooflights and dormers, and people most frequently book us about condensation that looks like a leak and wet patches on loft insulation.
In a village or hamlet like Holwell, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, which matters if you’re thinking of an insurance claim. We check whatever is safely visible and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What else we do in Holwell

DIY checks: what’s safe
A lot can be seen from the ground. 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.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Do you need a roof leak investigation in Holwell?
Flat roofs fail with age and wear. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks often start at the edges, upstands and outlets.
Most people get in touch after spotting one of these:
- Stains around a skylight
- Staining around the chimney inside
- Wet patches high on an inside wall
- Damp underlay across a wide area
Take an older house close to Church of St Peter (C of E) at Corner with Holwell Road: water on an older roof tends to find its way in at the lead, the valleys or the chimney.

Tips that help
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Take dated photos of the leak
- Put a bucket under the drip and move valuables
- Let us know about any past repairs to the roof
- Check the loft is accessible
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, so the repair is aimed at the cause.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and wear is easier to deal with before water gets in.
What happens on the day
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes about one to two hours, more where the leak is intermittent or the roof is large. For a village or hamlet like Holwell, the journey is planned in advance: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it is safe.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Clear the way to the loft hatch
- Have any questions written down, so nothing gets missed
- Keep pets out of the way during the survey
How to book
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or send us an email.

Roof leak investigations around Holwell
What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. The covering and its details give the first clues when tracing where water is coming from.
For site and facilities teams at buildings such as The Priory School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. For landlords with property near Hitchin station, a tenant living with a leak needs the cause found, not just the stain painted over.
