Thermographic Survey in Herne Bay

Herne Bay has a housing stock that rewards a closer look. The Census profile shows a strong share of semi-detached and terraced homes, and the age mix includes pre-1919 properties, 1919-1945 homes and a large block of post-war housing built between 1945 and 1980. That means we see solid brick walls, cavity walls, suspended timber floors and later concrete floor slabs in the same town. Each construction type loses heat in a different way, so a standard walk-through often misses the real source of the problem.

Local building materials also shape the thermal image. Traditional red and yellow stock brick, rendered finishes, concrete or clay roof tiles and, on some newer schemes, timber cladding all create different surface temperatures. Herne Bay sits on London Clay in the west and other formations further east, which brings a moderate to high shrink-swell risk and can affect floor and wall junctions over time. In the Central Herne Bay Conservation Area, where Victorian and Edwardian buildings sit alongside listed landmarks such as the Clock Tower and Bandstand, our surveyors often find older walls that have been altered, patched or insulated in stages rather than as one full retrofit.

New build activity also gives us useful contrast. home.co.uk currently lists Herne Bay Gardens in CT6 7GZ from £329,995 to £499,995, The Swale in Greenhill from £399,995 to £554,995, and Herne Bay Golf Club from £340,000 to £850,000. Those homes should perform better on heat retention, yet junctions, workmanship and later alterations can still leave weak spots around roofs, chimneys, glazing and service routes. That makes thermal imaging useful for buyers, sellers and owners who want to see what the build paper does not show.

Thermal images use colour to show surface temperature, not a normal photograph. Cold areas usually appear blue or purple, warmer surfaces move through green and yellow, and the hottest points can show red, orange or white depending on the camera palette. That means a dark patch in the image is not always a defect by itself, so we read the pattern, the building material and the position before drawing a conclusion. A cold wall in a shaded part of a terrace near the seafront can mean heat loss, while the same colour on a sunlit wall may simply reflect recent weather.

Reflections and solar gain can create false readings, which is why experience matters. Glass, glossy finishes and metal surfaces can throw heat signatures off, and a wall warmed by afternoon sun can mask a hidden bridge or leak. Our thermal imaging specialists account for those effects by comparing images taken from different angles and checking the building against known conditions. In practical terms, that means we annotate each finding with a plain explanation, so you know if the issue is insulation, moisture, air movement or a feature that needs more investigation.

The report is meant to be read, not guessed at. We point out the likely source, the extent of the anomaly and the type of remedy that may help, such as topping up loft insulation, sealing a window reveal, repairing failed flashing or checking pipework under floors. In Herne Bay, where many homes have been altered over time, that detail matters because a patch repair in a 1930s semi or a later extension on a Victorian villa can create a thermal bridge that does not show from the street.

Our thermal imaging surveys in Herne Bay start from £300, which gives homeowners a practical route into infrared diagnostics without the cost of opening up the building. That fee covers external and internal scans, review of the thermal images and an annotated report that sets out the findings in plain language. For bigger homes, coastal properties with more complex access, or buildings with several extensions, the price can rise because the survey takes longer and the analysis is more detailed.

Accuracy depends on the conditions on the day. The best results come from a property with the heating on for at least 2 hours and a clear temperature difference between inside and outside of at least 10C. We also prefer survey conditions from October to March, since cool weather makes heat loss stand out more clearly on the thermal camera. In a town with a mix of pre-1919 homes, 1945-1980 stock and newer developments on CT6 sites, that timing helps us separate real insulation faults from harmless surface changes.
