Infrared thermal imaging to detect heat loss and hidden defects








Bordon homes hold heat differently, and our thermal imaging specialists see that quickly on camera. We carry out detailed infrared surveys across GU35, from Dukes Quarter on Thorpe Close to Mill Chase Park on Miles Road and Whistle Wood on Station Road. Infrared imaging reveals cold spots, missing insulation, damp patterns and air leakage that stay hidden to the naked eye. The camera reads surface temperature variations to 0.1C, so a patch of heat loss stands out before it becomes a bigger bill. That matters in a town where energy waste can sit behind a clean-looking wall or a neat new extension.
Bordon's housing mix gives us plenty to inspect. homedata.co.uk records show an overall average house price of £385,212 in the last 3 months, with detached homes at £561,875, semis at £393,904 and terraces at £280,313, while sales totalled 117 in the last 12 months. The average price fell by -0.04% over 12 months and -0.22% over 5 years, so owners often want proof that comfort and running costs are under control. New homes at Whitehill Chase, Dukes Quarter and Forrester Mews bring modern insulation, yet thermal defects still appear around windows, loft hatches and service penetrations. Older terraces and converted homes can show a very different pattern, which is where our report helps.

Using listing data from home.co.uk and property data from homedata.co.uk
Our infrared cameras pick up temperature differences that the eye misses. A thin band of cold along a wall can point to missing cavity insulation, while a hot strip around a roof line can show where heat is escaping into the loft. We also detect cold bridging at junctions, air leakage around doors and windows, hidden damp and moisture ingress, underfloor heating faults and electrical hotspots. The survey is non-invasive and non-destructive, so we can check the fabric of the home without opening walls or lifting floors.
Local property types change the pattern we see. A terrace near the town centre can show pronounced heat loss at the loft hatch, party-wall junctions and the rear extension, while a newer home on Thorpe Close may reveal small but costly gaps around window reveals or service entries. Around GU35 0AP and GU35 0JF, our thermal imaging specialists often find that the building looks neat from the outside, yet the image tells a different story. That is the value of infrared work, it shows where the envelope breaks down.

Bordon is a town in motion, and the numbers help explain why thermal imaging matters here. homedata.co.uk records show 117 residential sales over the last year, a drop of 27 transactions or -23.08% compared with the previous year, so many owners are taking a closer look at running costs before they make a move. The town itself stood at 9,349 people in the 2021 Census, with a 2024 estimate of 10,827, while Whitehill and Bordon reached 21,129 in the same period. Nearly half of that wider population sits between 30 and 64 years old, with children under 15 at 18% and those aged 65+ at 16%, which points to a broad mix of household types and home sizes.
That mix matters because the fabric of the housing stock is varied. The majority of homes sold last year were terraced properties, yet the local market also includes semis and detached houses, plus newer schemes such as Dukes Quarter, Mill Chase Park, Whistle Wood, Forrester Mews and Whitehill Chase. Dukes Quarter at 48 Thorpe Close, GU35 9FD, has 2 and 4 bedroom homes from £350,000 to £495,000, while Mill Chase Park on Miles Road, GU35 0JF, starts from £329,995 and includes a 3 bedroom home at £415,000. New homes in these schemes use solar panels, triple glazing, EV charging ports and water-saving systems, but thermal imaging still finds weak points at junctions, openings and roof details.
Older homes need a different reading again. Red brick, burnt headers and tile hanging appear in the newer local build palette, while the town also carries homes with older layouts, altered lofts and later additions that may not match the original insulation standard. Near Deadwater Valley and Bordon Inclosure, moisture patterns can be confusing if a wall is cooled by ground conditions or shelter, so our surveyors compare the image with weather, elevation and room use before calling a defect. That local context turns a thermal picture into practical advice, because the same colour patch can mean different things in a terrace on a main road or a home facing woodland edge conditions.
Heat loss is rarely random. In many homes, around 25% of heat escapes through the roof, 35% through the walls and 15% through the windows, and a thermal image shows those losses as clear colour differences across the building fabric. That allows our surveyors to move from suspicion to evidence, which is useful when you are weighing up loft top-ups, draught proofing, insulated plasterboard or glazing upgrades. The report can also support a better EPC outcome because it shows where the thermal envelope is failing rather than relying on a general assumption.
Small repairs can make a large difference. A missed section of loft insulation above a hatch, a poorly sealed pipe penetration or a cold bridge at a flat roof junction can drag comfort down without showing any obvious crack or stain from the inside. In Bordon, that is especially relevant in homes where a new extension has been added to an older core, because the junction between old and new often becomes the weak point. Our thermal imaging specialists map those areas so you can prioritise the work that matters first, instead of paying for upgrades that do not tackle the real loss.

Choose a convenient slot and send over the property details. We use that information to plan the scan around the layout, access points and likely heat-loss areas.
The best results come between October and March, when the inside and outside temperature difference reaches at least 10C. We also confirm that heating has been on for at least 2 hours before the appointment.
The building needs an even heat signature before scanning begins. That helps the infrared camera read genuine defects rather than a cold house that has not been heated properly.
Our surveyors carry out external and internal infrared scans, moving room by room and elevation by elevation. The survey normally takes 1-2 hours depending on property size and complexity.
Each thermal image is checked, annotated and compared against the property layout. We look for repeat patterns, unusual cold patches, thermal bridges and signs of moisture or air leakage.
You receive a clear report with thermal images, plain English notes and practical recommendations. It shows what needs attention now, what can wait and what type of contractor may be needed.
Thermal images use colour to show temperature variation, not decoration. Cooler areas usually appear blue or purple, while warmer areas move towards red, orange or white, depending on the camera palette and the temperature spread across the surface. A cold stripe along a ceiling edge can indicate missing insulation, and a bright patch on a wall may show a heat source behind the surface. The image only becomes useful once it is read in the context of the building, the weather and the rooms below.
False readings do happen, so a good survey does more than capture a picture. Sunlight on a south-facing wall, a reflective surface, a recently opened window or heat from a radiator can all change the result, especially on homes around Station Road or High Street where elevations can catch different levels of sun. Our surveyors compare the thermal view with the visible fabric, so we do not mistake solar gain for a fault or a temporary warm patch for a leak. That careful reading matters in Bordon because a modern new build and a 1930s terrace can both show odd colour patterns for very different reasons.
Every finding is explained in plain language. We mark the exact location, describe the likely cause and set out the practical next step, whether that is insulation repair, sealing a draught path, checking a roof junction or asking a specialist to inspect damp. If the image suggests a wider issue, we say so, but we also separate a probable cause from a confirmed defect. That approach gives you a report you can act on, not a gallery of pictures that leaves the next step unclear.
The most common findings depend on the type of home, and Bordon has more than one pattern. Terraced properties, which made up the majority of sales last year, often show heat loss at the loft line, around rear extensions and through older window surrounds. Detached and semi-detached homes can expose bigger wall areas, so weak insulation or a cold bridge at a junction shows up fast on the thermal camera. In homes around GU35 0AP and the older parts of town, small defects can create a larger waste profile than the owner expects.
New build sites bring their own set of clues. Whitehill Chase, Dukes Quarter, Mill Chase Park and Whistle Wood all sit within a modern regeneration story, yet even these homes can reveal insulation gaps around service penetrations, loft hatches and window details. We also look at junctions where one material meets another, such as red brick against tile hanging or dark boarding near woodland edges, because that is where heat can escape first. Around Bordon Inclosure and Deadwater Valley, where ground moisture and seasonal conditions can affect surfaces, thermal imaging helps separate condensation from active ingress.

It can detect heat loss, missing or disturbed insulation, cold bridging, air leakage, hidden damp and moisture ingress, underfloor heating faults and some electrical hotspots. Our thermal imaging specialists use the camera to spot surface temperature changes that are often invisible during a standard visual inspection. In Bordon, that is especially useful in mixed housing stock, where a new build on Station Road can show different issues from a terraced home near the older town core.
Thermographic surveys in Bordon start from £300, with the final price depending on the size and layout of the property. Larger homes, extensions and more complex access can increase the time needed on site. If you are comparing options, a RICS Level 2 survey in Bordon starts from £395, but that is a different service with a different focus.
The best results usually come from October to March, when the temperature difference between inside and outside is at least 10C. That contrast makes heat loss easier to see on the infrared camera. Strong sunshine or a mild day can reduce the clarity of the image, especially on south-facing walls and roof slopes.
Most surveys take 1-2 hours, depending on the size and layout of the home. A compact flat will usually be quicker than a larger detached house with loft access, extensions and more elevations to scan. The analysis and report work happens after the visit, when each image is checked and annotated properly.
It can identify temperature patterns that often point to damp or moisture ingress, such as cooling caused by evaporation or a colder patch where water is affecting the fabric. We still read the result carefully, because condensation, recent cleaning and local weather can create similar patterns. In places near Bordon Inclosure or around older junctions, that extra context matters before a defect is labelled.
Yes, a little preparation helps the results. The heating should be on for at least 2 hours before the survey, and windows and doors should stay closed as much as possible once the property has warmed up. It also helps to clear access to loft hatches, boiler cupboards and the rooms that need scanning.
Yes, because new homes can still lose heat at the joins and openings where workmanship meets structure. We often check homes in developments such as Dukes Quarter, Mill Chase Park, Whistle Wood and Whitehill Chase for gaps around windows, service penetrations and roof details. A thermal survey can confirm that the promised energy performance is being delivered in real conditions, not just on paper.

Thermographic surveys in Bordon start from £300, and the price reflects property size, access and the number of rooms or elevations that need scanning. A small flat in a newer scheme will usually sit at the lower end, while a larger detached house or an older property with extensions will take longer and cost more. That is because the survey is not a quick look through a window, it is a measured infrared inspection of the fabric, inside and out. For homes in GU35, the cost often becomes easier to judge once the layout and the likely heat-loss points are clear.
The fee covers the site visit, the infrared scans and the annotated report. We do not hand over raw images and leave you to guess what they mean, because the value lies in the interpretation as much as the capture. Our surveyors compare the thermal pattern with room use, weather conditions and the visible fabric, then write clear recommendations that point to the next practical step. If the home sits near Thorpe Close, Miles Road or High Street, those details can change the reading, so the report is built around the property itself rather than a generic template.
Accuracy improves when the conditions are right. October to March gives stronger contrast, and heating for at least 2 hours before the survey helps the structure settle into a readable pattern. A temperature difference of at least 10C between indoors and outdoors gives the cleanest results, which is why we often ask clients to plan ahead rather than book at random. When the scan is done properly, you get a clear picture of where heat is leaving the home and which repairs will make the most difference.
