Thermographic Survey in St Davids

St Davids has a housing stock that rewards careful inspection. The town sits inside a conservation area designated in 1977 and extended in 1995, with around 115 listed buildings in the conservation area and about 120 listed buildings in the town itself, plus 11 Scheduled Ancient Monuments. Many of the older houses are late 18th and early 19th century townhouses, while newer buildings were added on the southern and eastern edges of the historic core. That mix means insulation standards vary sharply from one street to the next, and thermal imaging helps us compare them on equal terms.

Traditional homes in the town often use native Pennant stone and Cambrian Slate roof tiles, which look fitting in St Davids but can be unforgiving if insulation was added badly. Solid wall homes lose heat differently from cavity wall homes, so a retrofit that works in one property may leave gaps in another. Coastal weather adds another layer, with exposure to wind and driving rain increasing the chance of cold walls, penetrations and moisture tracking through junctions. Our thermal imaging specialists read those patterns alongside the building type, so the report reflects how the property is actually built.

Newer schemes in St Davids are useful contrasts. Maes Y Felin Phase Two includes 11 two-bedroom bungalows, while the wider scheme totals 58 homes with 18 affordable homes and 40 private and executive properties, and every home is reported to meet Welsh Government Development Quality Requirements with an EPC A rating and solar panels. Llys Menevia was also built with solar panels and air source heat pumps, which gives us a clear baseline for efficient construction in the area. When we scan both old and new homes, the thermal image shows how far the property sits from modern performance and which upgrades matter most.

The town’s population was 1,751 at the 2021 census, which gives the housing market a small and distinctive profile. That size matters because a short run of sales can shift the average, and homedata.co.uk records show the average price paid for properties in St Davids was £322,000 as of 9 April 2026, a fall of 5.6% over the last 12 months. House prices in postcode sector SA62 6 also fell -15.5% in the last year, while sales over the same period were 6% up on the previous year and 7% down on the 2022 peak of £388,993. In a market like that, an accurate thermal report helps buyers judge running costs as well as repair priorities.

Thermal images use a colour scale, with colder areas usually shown in blue or purple and warmer areas moving towards red, orange or white. A cold streak along a ceiling line may point to missing loft insulation, while a warm patch on an internal wall can suggest a hidden pipe, a heating fault or a patch of damp material. The image itself is only part of the story, so we read it alongside the property form, the weather and the construction type. That keeps the findings grounded in how the building actually behaves.

False readings matter as much as true ones. A wall that has been in direct sun can hold heat long after the surface should have cooled, and reflective finishes near a window can distort a camera’s reading. We also watch for wind-driven cooling, local heaters and recent occupancy patterns, because those can create heat signatures that look suspicious at first glance. Every thermal image we issue is annotated so you can see what is a genuine defect and what is just background behaviour.

In older St Davids homes, the difference between a useful image and a misleading one can be subtle. A Pennant stone wall may appear cooler than the plastered return beside it, or a slate roof may show a neat warm patch where insulation is missing around a junction. Our surveyors explain those contrasts in plain English, then link them to practical next steps. The result is a report that works for homeowners, buyers and anyone planning retrofit work on a historic property.

Thermal imaging surveys in St Davids start from £300, with the final fee shaped by property size, complexity and access. A compact terrace in the historic core may be quicker to scan than a detached home with loft conversions, cellars or multiple roof junctions. The survey includes external and internal infrared scans, annotated images and practical recommendations, so you receive a clear picture of where heat is being lost. For many owners, that report is the point where vague concerns turn into a fix list.

The cleanest results come from the right conditions. October to March is the preferred window, heating should be on for at least 2 hours before the visit, and a minimum 10C difference between inside and outside gives the strongest thermal contrast. That matters in St Davids, where stone walls, slate roofs and conservation-area details can produce subtle patterns that need a strong temperature spread to show properly. If you want a survey that highlights the real issues rather than the weather’s leftovers, the timing matters as much as the camera.
