Detect Heat Loss, Damp and Structural Issues with a Professional Thermal Imaging Survey
Are you noticing cold spots, high energy bills or signs of damp in your home? Many issues in residential properties go unnoticed until they cause real damage and that’s where a thermal imaging survey can help.
At Surveying Cymru, we provide expert thermal imaging surveys for homeowners and landlords looking to understand the thermal performance of their property. We can use infrared cameras to find hidden heat loss, insulation issues, moisture problems, air leaks, and more. This can be done quickly and accurately without disturbing walls or floors.
If you want to feel sure that your home is warm, energy efficient, and safe, start with a thermal survey.
What Is a Thermal Imaging Survey?
A thermal imaging survey, or thermographic survey, uses infrared technology. It measures temperature differences on walls, ceilings, floors, doors, and windows. The system then translates these temperature readings into visual images that show the distribution of heat in your property.
How Does It Work?
All objects emit infrared energy (heat) as a function of their temperature. A thermal camera detects this energy and creates a digital image based on temperature differences. These images can reveal:
- Heat escaping through uninsulated or poorly sealed areas
- Cold air entering through gaps or cracks
- Moisture intrusion and potential damp
- Electrical faults and overloaded circuits
- Underfloor heating or pipe issues
- Poorly performing cavity or party wall insulation
Because different materials retain heat differently, these surveys can uncover issues that would be invisible to the naked eye.

Why Homeowners and Landlords Use Thermal Imaging Surveys
Thermal imaging is a valuable diagnostic tool that can help prevent expensive repairs, improve comfort, and reduce energy waste. Here’s why more and more property owners are choosing this service:
Identify Heat Loss Quickly
Thermal surveys reveal exactly where your property is losing heat, whether through the roof, walls, windows, or floors. Once identified, you can take steps to improve insulation and lower your heating bills.
Detect Damp and Moisture Intrusion
Moisture in walls, ceilings or floors can often go undetected until it causes visible damage. Thermal imaging allows you to spot damp early by showing the colder areas where moisture is present, helping prevent mould growth and structural issues.
Check Insulation Performance
A survey will check if your cavity wall, party wall, or loft insulation is working well. It will also see if it has slumped, degraded, or was not installed correctly.
Diagnose Building Faults
Thermal surveys can find problems like missing insulation, cold bridging, air leaks, or flat-roof defects. This helps save time and money on repairs.
Verify Heating Systems
Thermal cameras can help locate underfloor heating pipes and check radiators for cold spots.

FAQs About Thermal Imaging Surveys
When is the best time to carry out a thermal survey?
Cooler months, early mornings or late evenings provide better conditions for detecting heat loss. Surveys during warmer periods may be less effective.
Is thermal imaging safe for my home?
Yes, it’s completely non-invasive and uses infrared light only. There is no risk to occupants, pets or property.
Do I need to prepare my home beforehand?
We recommend closing all windows and doors, running your heating for a short period before the survey, and keeping access to all rooms clear.
How long does it take?
A typical survey takes between 60–90 minutes, depending on the size and complexity of the property.
