Thermographic Survey in Barnstaple

Barnstaple has a housing mix that rewards careful inspection. In 2001, around 75.3% of homes in Barnstaple parish were houses or bungalows and 24.3% were flats, and the share of flats increased over the following decade. That pattern points to a town with a wide spread of property types, from compact apartments near the centre to larger houses in places like Bickington and Roundswell. Our thermal imaging specialists use that context to spot the weak points that often sit behind plaster, render or modern finishes.

Construction type matters as much as age. Many buildings in Barnstaple were made with Marland brick from the 1870s onwards, while Pottington brickworks produced Lauder and Smith bricks from local brown clay, and a few homes still use cob, including the Old Vicarage at 2 Vicarage Street. Traditional Devon construction also includes stone walls and natural slate roofs, which can store heat differently from modern cavity walls. That mix means a standard visual check can miss the real story, while thermal imaging shows where these materials are leaking warmth or trapping moisture.

The local development picture adds another layer. Barum Knoll, Bickington Park, Taw Wharf and planned sites at Landkey, Westaway Plain and Brynsworthy all point to a town that keeps changing around its older streets. Homeowners in newer estates often want to check for insulation gaps, missed seals around loft hatches, or poorly detailed roof junctions, while owners of older homes want to know if retrofitted insulation has left cold patches behind. Barnstaple’s built form is varied enough that one house can behave like three different property types in the same winter.

Thermal images use a colour scale to show temperature patterns across a surface. Cold areas usually appear blue or purple, while warmer zones show in red, orange or white, depending on the camera settings and the conditions on the day. That does not mean every blue patch is a problem, but it does mean the area deserves an explanation. Our surveyors read the whole picture, then link each image back to the building detail, the weather and the construction type.

Barnstaple properties need that level of interpretation because the same colour change can mean different things on different walls. A cold stripe on a solid wall in Newport may suggest heat loss through a bridge or a missing internal insulation layer, while a patch near a window on New Road might be caused by draught ingress rather than a structural fault. Sunlight, reflections from glossy finishes and recent rain can all distort a reading, so we avoid drawing conclusions from one frame alone. Each finding is annotated so you can see what is genuine and what is just a temporary effect.

The local building stock makes this even more important. In conservation areas such as Barnstaple Town Centre and Ebberly Lawn, older masonry and slate roofs can store heat differently from newer cavity wall homes in Bickington or on the edge of Roundswell. That means a thermal report has to explain the building, not just the image. We do that by linking the scan to likely causes, then setting out practical next steps that are realistic for the property.

Our thermal imaging surveys in Barnstaple start from £300. That price covers an infrared inspection, external and internal scanning where access allows, and an annotated report that explains the findings in plain English. It is a focused diagnostic service, so you are paying for temperature evidence rather than a general condition check. For homes in EX31 3 and across the wider Barnstaple area, that often gives a clearer first step than guessing where the heat is escaping.

Report delivery is usually prompt once the images have been checked and annotated. The exact timing depends on the property size, the complexity of the findings and how many elevations need review, but the aim is to turn the raw thermal data into something useful without delay. home.co.uk records show 151 recently sold properties in Barnstaple, which suggests an active local market where energy efficiency evidence can matter to both buyers and sellers. If you are comparing options, a thermal survey can sit alongside a RICS assessment by showing the performance issues behind the visible condition.

Best results come from the right setup. The survey should be booked for October to March, with the heating on for at least 2 hours before the visit and a temperature difference of at least 10C between inside and outside. That contrast gives our infrared cameras the thermal separation needed to show where warmth is leaking away. On a still, cold evening in Barnstaple, the results are usually far clearer than on a warm, sunny afternoon.
