Thermographic Survey in Coleraine

Modern homes in Coleraine are usually built with concrete block walls and concrete foundations, while older buildings often use cut stone such as limestone, granite or sandstone. Clay bricks also appear in parts of the older stock, and roof coverings can range from slate to clay tiles, artificial slate and mineral felt. That matters because each material loses heat differently, so a sandstone wall around The Diamond behaves very differently from a cavity wall in a newer estate. A thermal scan shows those differences clearly, room by room and elevation by elevation.

New-build activity around BT52 gives us another useful contrast. home.co.uk listings show Colemans Green on Burn Road, BT52 2FU, with 84 homes from apartments to semi-detached and detached houses priced from £100,000 to £180,000, while Lodge Gardens on Lodge Road runs from £230,000 to £265,000 and Henley Hall in Knocklynn sits from £300,000 to £330,000. LaurelHill Phase 3 near Laurel Park and Strand Road brings 80 social and affordable homes close to Killowen Primary School, and New Market Street at BT52 1EH adds 36 homes in apartments and duplexes. Even new buildings can hide missed insulation, open service penetrations or thermal bridges at slab edges.

Flood history changes the picture again. Coleraine sits on a floodplain near the confluence of the Bryan Creek and Konong Wootong Creek, and the town has recorded significant flooding in 1870, 1893, 1946, 1975, 1983, 1991 and September 2016. Thermal imaging helps after wet weather because damp plaster and moisture ingress often show as colder patches before staining becomes obvious. Homes close to the Young-Robertson Street drain system can benefit from a scan after heavy rain, especially where the building has older masonry or upgraded finishes.

Thermal images use colour to show temperature, not decoration. Cold blues and purples usually point to cooler surface areas, while reds and whites show warmer zones, so the picture tells us where heat is moving or being lost. A colder band along a ceiling line can suggest missing loft insulation or an air leak at the wall plate, and a patch beside a window can point to poor sealing. The image is only the start, so we read it alongside the property type and the weather on the day.

Temperature differences matter more than bright colour alone. A small 0.1C variation can be visible to the camera, but the pattern has to make sense in context before it becomes a finding. Reflections from glass, solar gain on sunlit walls and wind across external surfaces can distort readings, which is why our surveyors compare several views before making a call. A narrow hot spot near a socket can be harmless, while a wider band across a wall junction may show a cold bridge or trapped moisture.

Every report is annotated so the finding is easy to follow. We mark the area, explain why it appears that way and say whether the evidence supports a clear repair, a further check or simple monitoring. That approach helps buyers, owners and landlords read the same image in the same way. On homes around The Diamond and newer plots in Knocklynn, the same colour can mean different things, so the context sits beside every image.

Coleraine's flood history gives damp a local angle. The town sits on a floodplain near the Bryan Creek and Konong Wootong Creek, and the September 2016 event inundated residential, commercial and industrial buildings. After heavy rain, moisture can sit in masonry, skim and timber and show as a cooler patch long before the stain dries or mould spreads. Thermal imaging is useful in that moment because it shows where the cold is concentrated, not just where the paint has changed colour.

Thermal imaging does not replace a damp diagnosis, but it helps narrow the cause. Rising damp, penetrating damp and condensation each leave a different shape on the image, and a chimney breast in a Victorian terrace near The Diamond will not behave like a leaking flat roof on a newer block. Homes near the Young-Robertson Street drain system, or close to the river side of the town, can benefit from a scan after persistent rain. That extra context saves time when a builder, plasterer or damp specialist needs a clear starting point.

Thermal imaging surveys in Coleraine start from £300, with the final price depending on property size, access and the number of elevations we can scan. A compact flat on New Market Street will not need the same time on site as a detached house near Mountsandel Road, so the fee changes with the work involved. The survey includes external and internal infrared scans, image analysis and a clear written report with annotated findings. For homes that need a fast buying or repair decision, that mix of visual evidence and explanation is often the most useful part of the process.

Timing affects the quality of the result as much as the fee. October to March gives the strongest contrast between indoor warmth and outdoor air, and a minimum 10C difference helps the camera separate genuine losses from background noise. The heating should already have been on for at least 2 hours before we arrive, because warm fabric makes cold bridges and draught paths easier to see. A report can only be as useful as the conditions allow, so we plan the visit around the weather and the property type as well as the booking slot.

A thermal survey works best when it matches the property rather than the sales pitch. A sandstone building near The Diamond, a concrete-block house on Burn Road and a new apartment at Lodge Gardens all need a slightly different reading, because the fabric and heat flow are not the same. Our thermal imaging specialists look for the story behind the colours, then connect that story to a practical fix. That might mean a loft top-up, a cavity insulation check, a draught seal or a conversation with a damp specialist.

Coleraine's housing mix gives the survey real value because the town contains older masonry, newer estates and active development sites within the same area. homedata.co.uk records show a borough average of £257,191 in Q4 2025, while the current build-out around Colemans Green, LaurelHill Phase 3 and New Market Street shows how varied the stock has become. A good thermal report helps you choose where to spend first, which jobs can wait and which issues need another professional. The result is a clearer route to lower energy use and a more comfortable home.
