What is a thermal imaging survey?
Thermal images work best when the house is heated and the outdoor temperature is low, ideally at least 10°C lower than indoors, so surveys are booked for cold mornings or evenings. We image the top-floor ceilings, the room-in-roof if you have one and the loft, and explain what each cold patch is likely to be. More about a thermal imaging survey.

Building regulations in Wales
Wales has its own Approved Document L. Insulation alone is not normally notified, but conversions need building control. How the rules work across the UK.
Questions about a thermal imaging survey in Caernarfon
How soon can you visit a home in Caernarfon?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Do you take on jobs outside Caernarfon?
Yes. We also work in Llangefni and Bangor (Gwynedd) and elsewhere in Gwynedd.
Can a landlord in Caernarfon book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
When is the best time for a thermal imaging survey?
On a cold, still, dry day with the heating on for several hours. Bright sun or rain on the roof makes outside images unreliable.
Is a thermal imaging survey worth it?
It is most useful where a problem is hard to find or you want to check someone else's work. For a simple loft you can see into, a standard survey is usually enough.
