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.

How much does a thermal imaging survey cost in Porthmadog?

Questions about a thermal imaging survey in Porthmadog
How do I pay for work in Porthmadog?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you charge extra to travel to Porthmadog?
Not normally. Our guide prices include normal travel to Porthmadog. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can you visit Porthmadog outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
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.
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.
