Thermographic Survey in Horsham

Horsham's housing mix is broad enough to need different checks for different construction eras. Detached homes make up 33.6% of the stock, semi-detached homes 30.5%, terraced homes 18.2% and flats or maisonettes 17.1%, so a single inspection method would miss a lot of detail. The age split matters too, with 44.5% of homes built post-1980, 31.0% between 1945-1980, 13.5% pre-1919 and 11.0% between 1919-1945. In that context, a thermal survey helps separate genuine insulation failure from normal behaviour in a solid wall, a cavity wall or a modern timber frame.

Traditional brickwork, especially red brick, is common across Horsham, alongside tile hanging, render and the occasional weatherboard finish. Older homes around the centre were often built with solid walls or early cavity walls, while post-war estates from the 1950s-1970s sometimes received thinner insulation and less careful detailing than today's schemes. Home.co.uk listings show active new homes at Highwood Green, Broadacres, The Maples and Orchard Gate in RH12 4SE, with Barratt Homes, David Wilson Homes, Bellway and Cala Homes all present in the local market. Those newer houses can still benefit from thermal imaging, because rushed sealing around junctions, loft hatches or service runs is hard to spot without infrared.

Horsham's geology adds another layer. The Weald Clay formation has shrink-swell behaviour, so properties with shallow foundations or mature trees nearby can face movement, especially where moisture levels swing through the year. Thermal imaging does not diagnose subsidence, yet it can reveal the moisture patterns, cold edges and damp intrusion that often sit alongside movement in older homes. Add flood risk from the River Arun and its tributaries, plus surface water pressure during heavy rainfall, and you have a town where hidden moisture problems are worth checking before they become expensive repairs.

Colour matters in a thermal report. Cooler areas usually show as blue, green or purple, while warmer areas move towards red, orange or white, depending on the palette we use. In a Horsham townhouse or a flat in RH12 4SE, a blue patch may show missing insulation, a draught path or a damp area that is pulling heat out of the surface. A bright line across a ceiling can point to a thermal bridge at a joist, lintel or junction rather than a fault in the whole wall.

Solar gain can mislead an image if the wall has been heated by the sun, especially on the west side of a property after a bright afternoon around the town centre. Reflections from glass, shiny paint or metal can also create false highs, which is why we compare the image with the building form, the weather and the time of day. Our thermal imaging specialists annotate each frame so you know why a patch is significant and why another patch can be ignored. Electrical hotspots and underfloor heating faults stand out differently, and we flag those for the right follow-up rather than guessing at the cause.

The report works best when it reads like a building story, not a gallery of pictures. We explain how a cold edge at a loft hatch in a 1970s estate differs from a chilled patch on a solid wall in the Causeway conservation area. That context matters because Horsham's housing stock ranges from pre-1919 fabric to modern timber frame, and each type behaves differently under infrared. Once the reading is tied back to the construction, the next step becomes much clearer.

Thermographic surveys in Horsham start from £300. That covers external and internal infrared scans, image review and an annotated report that shows where heat is escaping, where cold bridging appears and where moisture patterns need follow-up. In a town where homedata.co.uk records show detached homes averaging £822,544 and flats averaging £252,536, a focused survey can be a small outlay before you commit to loft work or window upgrades. It gives you hard evidence before money goes into the wrong fix.

Larger homes in the older streets around the town centre or a more complex property near the Causeway may take longer to scan than a compact flat, so the exact fee depends on size and layout. Our best results come from October to March, with heating on for at least 2 hours and a minimum 10C difference between inside and outside. When those conditions line up, the thermal images are sharper and the recommendations are easier to trust. That is why we plan the visit carefully and explain the findings in plain English, not building jargon.
