Thermographic Survey in Blackpool

homedata.co.uk records for May 2024 show Blackpool's overall average house price at £165,000. Detached homes sit at £280,000, semi-detached at £185,000, terraced houses at £130,000, and flats at £95,000. The 12-month change was +2.5% overall, with detached at +3.0%, semi-detached at +2.0%, terraced at +2.8%, and flats at +1.5%. That price spread tells us why a relatively low-cost thermal survey can make sense before a purchase or after a retrofit.

Terraced houses make up roughly 40-45% of the Blackpool stock, with semi-detached homes at 30-35%, flats and apartments at 15-20%, and detached houses at 5-10%. Pre-1919 properties still form a significant share, then come many 1919-1945 semis and terraces, followed by post-war homes from 1945-1980 and newer developments after 1980. Around 141,000 people live in about 65,000 households, so the town carries a dense residential pattern where insulation defects and draughts can affect a lot of rooms quickly. Those figures are part of the reason our surveyors see strong value in a targeted infrared check.

Much of Blackpool's housing stock dates from the pre-1919 and inter-war years. Victorian and Edwardian terraces typically use solid brick walls, slate roofs, timber floor joists, and shallow brick footings, so heat loss through walls is common and condensation can build where ventilation is weak. Homes from 1919-1945 usually move to cavity brick walls and tiled roofs, yet many still have poorly filled cavities or later retrofit insulation that has left voids around bay windows and extensions. That mix shows why a thermal survey is so useful in areas like Raikes Hall and Stanley Park.

Post-war estates from 1945-1980 bring their own patterns. Cavity brick walls, concrete tile roofs, and suspended timber or concrete ground floors perform better on paper, but age, repointing, and later alterations often create cold bridges at junctions and patchy insulation where lofts were converted or topped up badly. Blackpool's clay-rich glacial till also brings moderate to high shrink-swell risk in some spots, so minor cracking can open up air paths around openings and service penetrations. Thermal imaging can show which temperature drops come from the fabric and which need a building survey follow-up.

Newer homes also benefit, especially in Foxhall Village on Foxhall Road FY1 5AL, The Gateway on Bispham Road FY2 0NR, and Cottam Hall Gardens at Cottam Hall FY4 5PL. Modern cavity wall construction and uPVC double glazing should hold heat well, yet workmanship gaps still appear around loft hatches, extractor vents, service entries, and party wall junctions. A brand-new home can still waste energy if insulation has been compressed or left discontinuous at the eaves. Blackpool's coastal wind and salt exposure make those weak points show up quickly on infrared images.

Thermal images are read on a colour scale, usually from cold blue to hot red or white. A colder patch on a wall does not always mean a defect, but when the same line appears across several images on a terrace in FY1 or a semi in FY4, it often points to a real heat path such as a missing cavity tie, an uninsulated lintel, or a draughty junction. Our surveyors compare inside and outside readings, then mark the exact area on the report so the image makes sense without guesswork.

Reflections, solar gain, and wet surfaces can fool the camera. South-facing walls warmed by afternoon sun may show false hot spots, while rain-soaked render can look colder than the structure beneath it, which is why we plan the survey around stable conditions and explain each image carefully. The infrared camera is sensitive to surface temperature variations to 0.1C, but interpretation still depends on building form, weather, and the history of any retrofit work. That is where our annotation matters.

Thermal imaging survey in Blackpool starts from £300. That price usually includes the infrared visit, external and internal scans, image analysis, and an annotated report with practical next steps. Because the survey is focused on heat loss, damp patterns, and insulation gaps, it is often the quickest way to decide whether you need draught sealing, insulation work, or a fuller building survey.

Accuracy depends on the conditions on the day. We get the clearest results between October and March, with the heating on for at least 2 hours and a minimum 10C temperature difference between inside and outside. The visit itself usually takes 1-2 hours, then our team reviews the images and issues the report soon after. On a windy Blackpool day, we may adjust timing so the reading reflects the building fabric rather than the weather.
