Thermographic Survey in Andover

Around East Anton and Picket Twenty, newer homes often appear efficient on paper, yet thermal images still reveal gaps at loft hatches, service penetrations, and junctions where insulation has been interrupted. In the older streets near the town centre, many homes were built before 1919 and were designed with solid walls, timber floors, and 18th-century sash windows in some properties. Those homes behave differently to cavity wall houses, so a surface temperature map helps separate normal heat flow from an actual defect. That matters when a property has been altered over time, because retrofits can hide a thermal bridge until winter makes it obvious.

The town's construction mix is broad. Traditional homes in Andover often use brick, stone, and timber frames, while later properties rely more on masonry, concrete blocks, steel, and modern timber frame methods. A Level 2 survey can note visible condition, but thermal imaging shows where the fabric is under stress from the inside out. That is useful in homes near Abbotts Ann or the proposed growth areas around Bere Hill and Finkley Down Farm, where housing can range from older stock to newly built shells with modern insulation expectations.

Older properties also carry more thermal risk at junctions and around patch repairs. Hard-cement repointing on lime walls, poor loft insulation, and failed seals around replacement windows can all create cold tracks that a visual inspection may miss in daylight. We often find that a property in the town centre conservation area has mixed construction, with original fabric beside later extensions. A thermal survey helps us identify which part is leaking heat, which part is holding moisture, and which part simply needs a better seal.

Thermal images use a colour scale that makes surface temperature changes easy to spot. Cooler areas usually show as blue or purple, while warmer surfaces move towards red, orange, or white. A cold patch on a wall does not automatically mean a defect, because some materials store and release heat differently, but repeated patterns across a façade often point to a real issue. The value of the scan is in the pattern, not the colour alone.

False readings can appear if a wall has been hit by direct sunlight, if a shiny surface reflects the surroundings, or if a radiator has just switched off. That is why we compare internal and external views, then annotate the image so the cause is clear. On a house near the town centre conservation area, a cold band by a window might be draught leakage, while on a newer home in Picket Twenty it may be a missing seal or insulation break. We explain the difference in plain language, so the report is usable rather than technical for the sake of it.

Surface temperature also helps us understand moisture behaviour. Damp materials often cool differently from dry ones, and that makes hidden ingress easier to spot around chimney breasts, parapet walls, or ground-floor corners. The camera does not replace a full investigation, yet it can point straight to the zone that needs moisture testing or a closer structural look. That saves time, and it stops good money being spent on the wrong repair.

The housing story in Andover is split between older fabric and planned growth. East Anton brought 1,061 homes, Picket Twenty added 534, and smaller schemes like Picket Piece with 82 homes and Harewood Farm with 150 homes changed the shape of the town. At the same time, Test Valley Borough Council has proposed land for over 2,500 houses around Andover, including sites at Bere Hill and Finkley Down Farm. That mix of completed, planned, and older stock gives thermal imaging a real role, because each building generation has its own weak points.

Moisture risk sits alongside heat loss here. Groundwater flooding has been a concern in surrounding villages, and historic flood locations in and around Andover have included Anna Valley, Kimpton, Goodworth Clatford, Monxton, and Enham Alamein. Add the town's conservation area and several Grade II listed buildings, and you get a local stock that often needs a careful eye on walls, roofs, and junctions. Thermal imaging is useful because it does not disturb the building, yet it still shows where heat and moisture are behaving badly.

Older homes built before 1919 can be excellent candidates for a scan, especially if they have been improved in stages rather than all at once. A loft top-up from one decade, new windows from another, and a later extension can leave hidden gaps between old and new construction. Around Andover College, Portway Business Park, and Walworth Business Park, the town's economic base has grown alongside its housing, so many owners now want a clearer answer on energy loss before they commit to upgrades. That is where a thermal survey earns its place.

Our thermal imaging surveys in Andover start from £300, with the final price shaped by property size, access, and the scope of the inspection. A compact flat near the town centre, a terrace in an older street, and a larger detached house near Abbotts Ann do not need the same amount of scanning time, so the quote reflects the job rather than a one-price-fits-all approach. The report includes external and internal infrared scans, annotated images, and practical recommendations that can be passed on to a builder or used when planning upgrades.

Accurate results depend on the right conditions. The heating should be on for at least 2 hours before we arrive, and the best survey window is October to March with at least a 10C difference between inside and outside. That gives the infrared camera the contrast it needs to read surface temperature properly, and it makes heat loss patterns much easier to interpret. Homes in East Anton, Picket Twenty, the town centre conservation area, and the surrounding villages all benefit from the same method, because the building fabric only gives up its secrets when the thermal contrast is strong enough.
