Infrared thermal imaging to detect heat loss and hidden defects








Our thermal imaging specialists carry out detailed infrared surveys across Burnley, using cameras that read surface temperature changes with 0.1C accuracy. The images show where heat escapes, where insulation has failed, and where cold air is entering through gaps that ordinary inspections miss. Thermal imaging is non-invasive and non-destructive, so we can map defects without lifting floors or opening walls. You get clear evidence, not guesswork.
Burnley homes often include a mix of terraced properties, semis, detached houses, and flats, so heat loss does not always appear in the same way from one address to the next. Older terraces can hide cold bridges at party wall junctions, while newer homes can still show poor insulation around roof lines, windows, or service penetrations. A thermal survey helps cut through that uncertainty. It shows where energy is being lost, which can improve comfort and reduce wasted heating.

Our surveyors use infrared imaging to trace heat patterns across walls, roofs, floors, windows, and doors in Burnley. The camera highlights missing loft insulation, collapsed cavity fill, cold bridging, and air leakage around frames or sealant lines. It can also reveal hidden damp where moisture changes the surface temperature. The result is a fast visual map of the parts of the property that need attention.
Thermal imaging can also pick up underfloor heating faults and electrical hotspots, which is useful when a room feels unevenly heated or a circuit is working harder than expected. On a Burnley property, that matters because one cold corner may point to a local insulation defect rather than a whole-house problem. Our thermal imaging specialists separate the real issue from the visual noise. That saves time on repairs and keeps the focus on the right fix.

Burnley has housing that often responds well to thermal analysis because the same street can include more than one construction era. A terrace, a semi-detached house, and a later flat can all lose heat in different ways, even when they share the same weather exposure. Thermal imaging gives a side-by-side picture of those differences. That is useful for homeowners who want to know where heating bills are being wasted.
Older properties are common across many Lancashire towns, and their original construction standards were not designed around modern insulation targets. Solid walls tend to bleed heat more quickly than insulated cavity walls, while later retrofits sometimes leave gaps around loft hatches, eaves, pipework, or replacement windows. Burnley homes with previous upgrades can still show patchy results if the work was incomplete. The thermal camera exposes those weak points in a way that a standard visual inspection cannot.
We also see value in thermal surveys where buyers want evidence before they commit to improvements. A house may look tidy on the surface, yet still have cold spots that point to missing insulation or draught paths behind plaster. In Burnley, that sort of finding can affect comfort during the colder months and influence the order of repair works. Our surveyors translate the images into practical next steps, so you know what to improve first.
Thermal imaging turns hidden heat loss into something you can see and act on. In many homes, around 25% of heat can escape through the roof, 35% through the walls, and 15% through windows, which makes the camera a powerful tool for finding the biggest losses first. Burnley properties with weak loft insulation or ageing windows often show these patterns very clearly on an infrared scan. That gives you a priority list rather than a vague warning.
The report is useful for energy decisions because it links visible defects to likely savings and comfort gains. If a Burnley home has cold bridging at a junction, missing cavity insulation, or leakage around openings, fixing those issues can support a stronger EPC position over time. Some upgrades are straightforward, like top-up loft insulation or draught sealing, while others need a contractor to inspect cavity fill or joinery. Our thermal imaging specialists show which works are worth doing first, based on what the camera finds.

Start by booking a thermal imaging survey through our quote form. We confirm the property details, access needs, and the best time for the visit, then plan the survey around conditions that give a strong temperature contrast.
For the clearest reading, the heating should be on for at least 2 hours before the survey. A minimum 10C difference between inside and outside helps the infrared camera show heat loss with much better clarity.
Our surveyors carry out external and internal infrared scans across the Burnley property. We look at walls, ceilings, floors, windows, doors, loft spaces, and service penetrations, then check for signs of moisture or abnormal heat build-up.
After the site visit, the thermal images are reviewed and annotated. We separate genuine defects from reflections, solar gain, and other false readings, so the findings stay accurate and useful.
You get a clear written report with thermal photographs, notes on each defect, and practical recommendations. Most surveys take 1-2 hours depending on property size, and the final report explains what to fix first.
Use the report to guide insulation upgrades, draught proofing, repair work, or further specialist checks. That gives Burnley homeowners a simple route from inspection to action.
Thermal images use a colour scale rather than a normal photograph. Cold surfaces usually appear in blue or purple tones, while warmer areas move through yellow, orange, red, and sometimes white. That does not mean every bright patch is a defect, because sunlight, reflections, and recent heating patterns can change what the camera sees. Our surveyors explain each image in plain terms so the meaning stays clear.
The important point is the temperature difference between one area and the next. A cold stripe on a ceiling line can point to missing loft insulation, while a sharp pattern around a window frame may show air leakage or failed seals. In Burnley, that kind of contrast is useful on terraces and semis where heat can move quickly through weak joints. The image alone is only the start, and the annotation turns it into evidence you can use.
False readings can happen, especially if a wall has been warmed by direct sun or a surface is reflecting another heat source. That is why good survey work depends on timing, lighting conditions, and careful reading of the building fabric. We cross-check the thermal image against the property layout, construction style, and what can be seen on site. The final report keeps the interpretation grounded, not speculative.
Across Burnley, our thermal imaging specialists often find heat loss at roof level first, especially where loft insulation is thin, uneven, or interrupted around storage boards and hatch openings. Terraced homes can show cold bridging at party wall junctions, while semis may reveal leakage around bay windows or replacement frames. The camera makes these patterns obvious within minutes. That helps homeowners focus on the parts of the property that are actually losing energy.
We also find damp-related signatures where moisture has entered through flashing, cracked render, poor pointing, or failed seals around openings. These areas can look minor from the outside, yet the thermal image often shows a cool patch that tells a different story. On some Burnley homes, the issue is not a major structural defect, but a smaller ingress route that has been ignored for years. Early detection keeps repairs simpler and less disruptive.

A thermal imaging survey can detect heat loss, missing insulation, cold bridging, draughts, damp-related temperature patterns, and some electrical hotspots. It can also highlight underfloor heating faults and problem areas around windows, doors, roofs, and floors. In Burnley, that helps us identify where a home is performing badly without opening it up.
Our thermal imaging surveys start from £300. The final price depends on property size, access, and how much detail is needed in the report. For Burnley homes, the cost normally includes external and internal scans, image analysis, and a written report with recommendations.
October to March gives the clearest results because the temperature difference between inside and outside is stronger. We look for at least a 10C difference, which helps the infrared camera show heat loss more accurately. A cold, dry evening often gives better contrast than a mild day.
Most surveys take 1-2 hours, depending on the size and layout of the property. Larger homes, tricky access, or extra areas such as lofts can take longer. The image review happens after the visit, so the report is more detailed than the time on site suggests.
Thermal imaging can help identify signs that often point to damp, such as cooler surface patches or patterns linked to moisture ingress. It does not replace a specialist damp diagnosis on every case, but it gives strong clues about where water may be entering. In Burnley, that can be very useful where leaks are hidden behind finishes.
Yes, a little preparation improves the results. The heating should be on for at least 2 hours before we arrive, and internal doors should stay open unless we ask otherwise. It also helps to avoid opening windows or running extract fans just before the survey, because that can distort the thermal pattern.
They work on most property types, including terraces, semis, detached houses, and flats. Some buildings give clearer thermal contrast than others, especially when the temperature difference is strong. In Burnley, that means the survey can still be useful even where the construction style changes from one street to the next.

Our thermal imaging surveys in Burnley start from £300, which keeps the service accessible while still allowing for a proper site visit and report. That price covers the infrared inspection, professional analysis, and a clear explanation of what the images show. If the property is larger or has extra rooms, access challenges, or complex insulation issues, the final quote may rise. We always set out the scope before work begins.
The report usually arrives after the images have been reviewed and annotated, so you are not left guessing what each colour band means. For Burnley homeowners, that matters because the value of the survey lies in interpretation, not just in the camera work itself. We show where heat is escaping, which areas need repair, and which defects are likely to affect comfort or running costs. The outcome is a practical plan, not a pile of pictures.
Conditions on the day still matter, even with skilled analysis. October to March normally gives the strongest contrast, and the heating should be on for at least 2 hours before we arrive. A minimum 10C difference between inside and outside helps the infrared camera separate real defects from background noise. That is why our thermal imaging specialists always check timing as part of the booking process.
Burnley properties can hide expensive energy loss behind surfaces that look perfectly sound. A room that feels cold near one wall may be telling you about missing insulation, a failed seal, or a cold bridge at a junction that the eye cannot see. A thermal survey turns that discomfort into measurable evidence. Once you know the cause, you can target the fix.
Homeowners in Burnley often use the survey before insulation upgrades, after draught-proofing work, or when a property still feels cold despite the heating being on. It also helps buyers who want to understand what a visual survey may not catch. Our thermal imaging specialists keep the process simple, direct, and focused on the parts of the building fabric that matter most. That makes the findings easier to act on.
Because the survey is non-invasive, it avoids the disruption associated with intrusive checks. You do not need to cut open finishes or remove fixtures just to find out where the heat is going. The camera does the reading, and the report turns it into a clear set of recommendations. For many Burnley homes, that is the fastest route from suspicion to evidence.
Every report is built around the property we have inspected in Burnley, not a generic template. We note where heat loss is visible, where moisture patterns need closer attention, and where insulation defects are likely to be costing energy. The images are annotated so each issue is easy to understand. That is especially useful if you want to pass the findings to a contractor.
We also explain the likely priority of each recommendation. A missing loft insulation section may be a quick win, while damp around a window reveal or roof detail may need a separate repair plan first. The report helps you decide what to do immediately and what can wait. That kind of ordering stops homeowners from spending money in the wrong place.
In practical terms, the survey gives Burnley buyers and owners a clearer picture of how the building performs. It can support retrofit decisions, inform maintenance, and reduce the chance of paying for cosmetic work before fixing the cause of the heat loss. If you want evidence that links comfort, energy use, and building fabric together, the thermal report does that job well.
Our thermal imaging specialists get the clearest Burnley results between October and March, with the heating running for at least 2 hours before the visit. A 10C temperature difference between inside and outside gives the camera the contrast it needs to show heat loss, cold bridging, and hidden leakage more clearly. The survey remains non-invasive and non-destructive, so it is a clean way to check a home's energy performance before spending on upgrades.
Yes, and that is one of the best uses for it. The survey shows whether the existing insulation is thin, uneven, or missing around the hatch and eaves. In Burnley homes, that helps you avoid topping up a loft that still has hidden weak points.
No single survey sees everything, and thermal imaging is no exception. It is excellent for surface temperature patterns, heat loss, and many moisture-related clues, but it does not replace a structural inspection where movement or settlement is suspected. We use it to answer the energy and defect questions it is designed for.
Yes, we normally carry out both external and internal scans where access allows. That gives a fuller picture of how Burnley homes are losing heat through walls, roofs, windows, and floor junctions. It also helps us check whether a cold area is caused by the building fabric or by a local condition inside the room.
The report is issued after the images have been reviewed and annotated, so the timing depends on the size and complexity of the survey. Most homeowners receive a clear written result shortly after the visit. The focus is on accuracy, not speed alone.
Yes, it can reveal unusual hotspots that may point to overloaded circuits, failing components, or poor connections. We only report what the camera can show with confidence, and we avoid overcalling any issue. If something looks abnormal, the thermal image gives you a reason to ask for a specialist electrician to inspect it.
It can be very useful, especially where a home feels cold or has had partial insulation upgrades. Buyers get a better sense of whether the property needs targeted improvement or more detailed follow-up work. That can be helpful before budgets are committed to repairs or refurbishment.
