Infrared thermal imaging to detect heat loss and hidden defects








Our thermal imaging specialists carry out detailed infrared surveys across Arbroath and the wider Angus area. The camera reads surface temperature differences that the eye misses, so cold patches, air leakage, missing insulation and moisture patterns show up clearly. Because infrared cameras detect surface temperature variations to 0.1C accuracy, we can build a sharp picture of how the fabric is performing. The survey is non-invasive and non-destructive, which suits buyers and owners who want facts before spending on upgrades.
Arbroath currently has 121 listings for sale on home.co.uk, yet the same source says there is not enough sold price data available for Arbroath to display trends over the last 12 months. That makes a fabric-led check even more useful, because asking prices alone do not tell us where heat is escaping or why rooms feel uneven in DD11. A thermographic survey helps us separate cosmetic presentation from real performance. It also gives clear repair priorities for lofts, windows, floors and wall junctions.

Our thermal images pick out heat loss through roofs, external walls, floors and glazing. Missing cavity wall insulation, compacted loft insulation and air leakage around sills often appear as sharp colour contrasts, while cold bridging shows up at junctions where materials meet. Moisture ingress can leave cooler patches too, especially after rain or where ventilation is poor. Internal scans can also flag hotspots from underfloor heating defects or overloaded electrical circuits.
Each scan is taken with the property warmed up, so the temperature pattern reflects the building fabric rather than the day's weather. We can read the image to 0.1C accuracy, then mark the exact area that needs follow-up. That matters in Arbroath because a neat finish can hide gaps around pipes, loft hatches or replacement windows. The report turns those patterns into practical actions, not guesswork.

Arbroath sits in Angus, and the local market picture is thin enough that home.co.uk says there is not enough sold price data available to display trends. In that setting, thermal imaging gives a clearer route into property condition than broad market assumptions. We do not need to know the age or style of every house to see where heat is leaking from the one in front of us. The scan is about the building fabric, not the brochure.
That approach works well where a town has mixed construction and retrofit histories, because insulation can be present in one part of a property and absent in another. A loft may have added mineral wool, while a dormer, eaves detail or boxed-in pipe chase still leaks heat. A wall can also show patchy performance if retrofit work was done in stages. Our surveyors read those changes straight from the thermal pattern.
Older homes often need a closer look at junctions, but newer homes are not free from defects. Window replacements can leave cold edges, cavity insulation can be uneven, and draughts can creep in around services. In Arbroath, that means a survey is useful whether the property has been refreshed recently or has had very little work done. The image tells us where comfort is being lost, room by room.
A thermal survey turns heat loss into something visible. On a typical scan, the roof can account for 25% of heat loss, walls 35%, and windows 15%, so the biggest loss is not always where people expect it. In Arbroath, those figures help owners decide whether loft top-ups, draught sealing or window repairs should come first. The report ties the image to a repair list, so every finding has a job to do.
Energy savings follow from the fixes, not the camera itself. Once we show where heat is escaping, it becomes easier to judge which upgrade is likely to cut bills fastest and which one can wait. The same evidence can support EPC improvement planning, because better insulation and tighter air sealing often help the rating edge upwards. We also point out which recommendations are likely to have the shortest payback period, such as loft insulation top-up or draught proofing, before larger fabric work is considered.

Select the Arbroath survey slot, then tell us the property type and access details.
Keep the heating on for at least 2 hours before the appointment so we get a strong temperature contrast.
October to March gives the clearest thermal contrast, and we aim for a minimum 10C difference between inside and outside.
Our surveyors take external and internal infrared images, then check problem areas such as loft spaces, walls, windows and floor edges.
We annotate each frame, separate real faults from reflections or solar gain, and link the findings to likely causes.
You get a clear report with thermal images, repair priorities and practical next steps for the Arbroath property.
The colour scale is the first thing to read. Cold areas usually show as blue or purple, while warmer surfaces move towards red, orange and white. A cold patch does not always mean a defect, because a reflection or a surface exposed to sunlight can skew the reading. We always compare the image with the building context before we call a fault.
Temperature differentials matter more than colour alone. A weak contrast can hide a problem, while a strong contrast can make a leak stand out sharply around a window frame or a cold bridge at a junction. That is why our surveyors ask for the heating to be on and for the property to have been warmed up properly before the scan. The final report explains each image in plain language, so the cause and the fix are linked together.
In Arbroath, that explanation matters because a neat internal finish can conceal the source of heat loss. We label every image, mark the exact location, and explain if the clue points to insulation failure, air movement or moisture. You do not need to read the thermal picture alone. We do the translation for you.
This varies street to street, so we go on your exact address rather than a town-wide average. That means we do not assume a property is solid wall, cavity wall or post-1980 build until the image tells us more. The survey often finds lost heat at loft hatches, patched insulation around tanks, and draughts at replacement window junctions. Those clues are more useful than guesswork.
When retrofits have been done in stages, the thermal image may show one wall behaving well while the adjoining wall leaks heat. We also see cooler bands where insulation stops short, or where a previous alteration left a break in the fabric. In older homes, that contrast can be stark, especially around bay areas, floor edges and chimney breasts. The point is simple: the image tells us where the work was missed.

It can spot heat loss, missing or damaged insulation, air leakage around doors and windows, cold bridging at junctions, hidden damp patterns and hotspots from underfloor heating or electrical circuits. Infrared cameras read surface temperature differences to 0.1C accuracy, so the defects show up before they are obvious indoors. In Arbroath, that can help explain draughty rooms or a cold wall that has been dismissed as normal. We then mark the issue in the report and say what to check next.
Our thermographic surveys start from £300. That fee covers the infrared inspection, the image analysis and a report with annotated findings and recommendations. For a home in Arbroath, the value is in seeing where to spend first rather than guessing at insulation work. If the property needs follow-up with another survey type, we can point you to the right next step.
October to March gives the clearest results because the temperature difference between inside and outside is easier to create. We aim for a minimum 10C difference, which helps the camera highlight leaks and cold bridges. Bright sun can muddy an external image, so cooler months usually work best in Arbroath. If there is a specific issue to check, we can still advise on timing.
Most surveys take 1-2 hours, depending on the size and access in the property. A compact Arbroath flat will usually be quicker than a larger house with loft access and several elevations to scan. We then spend time analysing the images so the report is clear and properly annotated. The inspection is quick, but the reporting is where the evidence gets turned into useful advice.
It can show patterns linked to damp, such as cooler areas caused by moisture evaporation or water ingress. It does not diagnose every cause on its own, so we read the image alongside the building context and the weather conditions on the day. A damp-looking patch in Arbroath might be linked to ventilation, failed seals or a roof detail rather than a single obvious leak. We flag the area and explain what a follow-up check should target.
Yes, a little preparation helps the scan. Please keep the heating on for at least 2 hours before the appointment, close windows and doors, and avoid blocking the areas you want checked. If strong sunlight has been hitting one side of the property in Arbroath, we may adjust the timing so the image is not skewed by solar gain. Good preparation gives cleaner readings and a better report.
We can use it on most homes, but the results are strongest when there is a clear temperature difference and access to the main fabric. Flats, terraced homes and detached houses all benefit if the camera can see the relevant surfaces. In Arbroath, that means we can usually build a useful picture whether the property is compact or larger. The key is access, heating and the right weather window.
Thermographic surveys start from £300, and the fee covers the infrared inspection, the image analysis and a written report. In Arbroath, that matters because home.co.uk currently lists 121 properties for sale, yet the same source says there is not enough sold price data available to display trends over the last 12 months. A thermographic report gives a direct look at the building fabric, which is often more useful than a thin market signal when you are deciding on upgrades or pre-sale works.
We aim for the clearest conditions from October to March, with the heating on for at least 2 hours and a minimum 10C difference between inside and outside. That contrast helps the camera pick out missing insulation, air leakage and cold bridges without the noise that bright sun can create. The inspection usually takes 1-2 hours, then we move into image analysis and annotation. Once the report is ready, you can see which jobs are urgent, which ones are routine, and which ones can wait.
That makes the survey useful for buyers, sellers and owners in DD11 who want a practical maintenance plan. If the images point to a broader building issue, we can suggest a Level 2 or Level 3 survey next. The aim is straightforward: use the thermal evidence first, then choose the right fix.
