Infrared thermal imaging to detect heat loss and hidden defects








Our thermal imaging specialists carry out detailed infrared surveys across Wigan, using cameras that read surface temperature changes down to 0.1C. That lets us see what the eye misses, from heat loss around window reveals to cold patches that can point to missing insulation, air leakage or moisture ingress. The method is non-invasive and non-destructive, so there is no need to open up walls or lift finishes just to find the source of a problem.
Home.co.uk records show the average asking price in Wigan was £218,606 in May 2026, with 1-bedroom homes at £112,507, 2-bedroom homes at £143,325 and 3-bedroom homes at £202,762. Those figures make it worth checking how well a property holds heat before winter bills start climbing. Our surveys are a practical way to see where energy is escaping, which rooms are suffering from cold spots, and where a small repair could improve comfort fast.

Infrared imaging shows surface temperature differences that often reveal heat loss through lofts, walls, floors and glazing. It can also identify missing or collapsed cavity wall insulation, cold bridging at junctions, gaps around doors and windows, and the kind of draught path that makes a room feel colder than the thermostat suggests. In Wigan homes, that matters because the problem is often hidden behind plaster, trims or sealed finishes.
Our surveyors also look for signs of hidden damp, moisture ingress, underfloor heating faults and electrical hotspots. A damp patch may not always be a leak, but a thermal image can show where cold material, trapped moisture or poor ventilation is changing the surface temperature. That gives you a clearer starting point, so repairs are based on evidence rather than guesswork.

Wigan has a practical mix of homes, and the local market reflects that spread. Home.co.uk lists Willowbrook Fields on Seaman Way, Ince, WN2 2FP as 2-bedroom homes available for shared ownership, while The Seasons at 1A Worsley Mesnes Drive, Worsley Mesnes, WN3 5YD includes terraced to detached new-build houses from Keepmoat. Bakers Court in WN2 1HB is also on the local map, with 2 and 3 bedroom houses through Your Housing Group, and a 40% share priced at £98,000 - £118,000 against a full market value of £245,000 - £295,000.
That mix is exactly where thermographic surveys earn their keep. New-build homes can still suffer from insulation gaps at joists, service penetrations, window perimeters or loft hatches, especially if the build has been adapted or occupied before a final check has been done. Older homes in Wigan can show a different pattern, with more obvious draught paths and colder junctions, but the thermal camera still points us to the same outcome - the parts of the fabric losing heat first.
Wigan Council's draft local plan in May 2025 adds another reason to check performance early. Westwood Park is proposed for around 420 homes and new employment space, South Hindley is earmarked for up to 2,000 homes, and North Leigh Park is set out for around 1,400 homes. Moss Bank Court, Heysham Road and City Road in Orrell are also under development work, which means thermal checks are useful both after completion and once homes have settled into real use.
A thermographic survey turns heat loss into something you can actually see. In many homes, the biggest losses show up in three places, 25% through the roof, 35% through walls and 15% through windows, with the rest spread across floors, vents and small leakage points. Those figures do not belong to every property in Wigan, but they do explain why a roof, wall or glazing issue can make a noticeable difference to bills.
Our reports link those images to energy-saving action. If the loft is under-insulated, the recommendation may be a top-up or a check around the hatch. If the walls show a repeating cold pattern, we may flag cavity insulation issues, thermal bridging or a construction detail that needs closer inspection before any upgrade is signed off.
The value is not just in finding defects. A thermal survey helps you decide which works should come first, so money is spent on the areas with the clearest heat-saving return. For a Wigan property near the WN2 or WN3 schemes, that can mean separating a simple draught problem from a wider insulation issue before you commit to more expensive repairs.

For the clearest results, we aim for October to March, with the heating on for at least 2 hours and a minimum 10C difference between inside and outside.
Keep windows and external doors shut before the survey, clear access to loft hatches and key walls, and leave heating running so the fabric has time to warm through.
Our surveyors complete external and internal infrared scans, checking walls, roofs, floors, windows, junctions and any areas that show an unusual temperature pattern.
We review each thermal frame, rule out false readings such as reflections or solar gain, and annotate the findings so the cause of the cold or hot spot is easy to follow.
You get a clear report with thermal images, labelled defects and practical recommendations that point to the next repair, upgrade or further check.
A thermal image looks simple at first glance, but the colours carry useful detail. Cold areas usually appear blue or purple, while warmer surfaces move through red and white depending on the camera palette. On a Wigan property, that contrast can make a cold wall junction, a leaking window seal or a patchy loft insulation layer stand out in seconds.
Temperature difference matters. Our infrared cameras detect surface variation to 0.1C, so a small change can still point to a bigger fabric problem underneath. We also watch for false readings caused by reflections from glass, shiny metal, standing water or solar gain on sunlit elevations, because a bright patch is not always a defect.
Every finding is annotated in plain English. If the thermal pattern suggests a thermal bridge, we explain the junction involved. If it points to trapped moisture, air leakage or a possible heating fault, we set out what the image shows and what should be checked next, so the report can be used by a contractor, buyer or homeowner without needing a technical translation.
The local homes we see in Wigan often show repeating thermal patterns rather than random defects. Willowbrook Fields in Ince, WN2 2FP and Bakers Court in WN2 1HB are both good examples of schemes where insulation continuity, window perimeters and loft details deserve a close look once the home is occupied. A camera picks up those gaps quickly, even when the finish looks clean.
On the other side of town, The Seasons at 1A Worsley Mesnes Drive, WN3 5YD is the sort of development where we would expect a thermal check to pick up cold spots around openings, services and roof spaces if the fabric has not settled as intended. The proposed schemes at Westwood Park, South Hindley and North Leigh Park will need the same kind of checking once homes are in use, because a clean finish does not always mean a flawless thermal envelope.

It can detect heat loss, missing insulation, cold bridging, air leakage, damp patterns, moisture ingress and some electrical hotspots. In Wigan homes, that often means checking around lofts, windows, floors, pipe runs and wall junctions where temperature changes show up first. Our surveyors then explain what the image suggests and which follow-up action makes sense.
Our thermographic surveys start from £300 in Wigan. The final price depends on property size, access and how much imaging time is needed, especially if the home has several floors or outbuildings. You get a non-invasive survey, an annotated report and practical recommendations as part of the service.
October to March gives the best thermal contrast, so defects are easier to spot. We also look for at least a 10C difference between inside and outside, with the heating on for at least 2 hours before the visit. Those conditions make cold bridging, insulation gaps and draught paths much clearer.
Most surveys take 1-2 hours, depending on the size and layout of the property. A compact flat near Wigan town centre will usually be quicker than a larger detached home or a property with extensions. The image analysis and report writing happen after the visit, once the thermal frames have been checked properly.
Yes, it can often highlight the temperature pattern linked to damp or moisture ingress. A damp area is usually cooler than surrounding dry material, although the camera cannot tell you the exact cause on its own. If the pattern is unclear, we will flag it as an area that needs a moisture check or closer inspection.
A little preparation helps a lot. Keep the heating on for at least 2 hours beforehand, shut windows and external doors, and make sure loft hatches, main walls and any problem rooms can be accessed easily. If a room in Wigan has been heavily shaded or sunlit earlier in the day, we may factor that into how the images are read.
It will show whether the fabric is losing heat in a way that suggests the insulation is patchy, missing or poorly installed. That is useful on both older Wigan homes and newer schemes such as Willowbrook Fields or The Seasons, where a visual finish can hide a thermal weakness. The report makes the next step clearer, whether that is top-up insulation, sealing gaps or a further specialist check.
Yes, especially if you want to understand running costs before you commit to a property in WN2, WN3 or the wider Wigan area. It will not replace a full structural survey, but it can reveal heat loss and damp patterns that matter once you start living there. Buyers often use it alongside a Level 2 or Level 3 survey for a fuller picture.

Thermal imaging surveys in Wigan start from £300, which keeps the first step straightforward for homeowners who want real evidence before spending on repairs. The price covers external and internal infrared scans, image review and a report with annotated findings, so you can see which part of the building fabric is underperforming. For homes priced at the Wigan average of £218,606 on home.co.uk, that is a modest check against the cost of chasing problems blind.
Accuracy improves when the conditions are right. Heating should have been on for at least 2 hours, the inside and outside temperatures need a gap of 10C or more, and the survey works best from October to March. Once the visit is complete, we review each frame, flag false readings where needed and return the report with clear recommendations, so you can act on the heat loss rather than just look at the picture.
