# Thermal Drone Survey > A thermal imaging survey flown with a radiometric camera, showing where a building loses heat or holds water, read by someone who explains the limits. Homeowners and landlords chasing heat loss, damp or missing insulation, plus managing agents who need a flat roof checked for trapped moisture. A radiometric thermal survey shows where a building is losing heat or holding water on the day it was flown, in that day's conditions, read by someone who tells you plainly what it does and does not prove. ## Services - [Thermal Roof and Building Survey](https://thermal-drone-survey.co.uk/services/thermal-roof-survey): A radiometric thermal pass over the whole roof and elevations alongside a 100 megapixel visual survey, written up with what the temperature pattern actually shows within 48 hours. - [Heat Loss and Insulation Gap Survey](https://thermal-drone-survey.co.uk/services/heat-loss-survey): A targeted thermal check on a cold room, a suspected patch of missing loft insulation, or a cold bridge at a wall junction, aimed at homeowners with a symptom rather than a vague worry. - [Damp and Flat Roof Moisture Survey](https://thermal-drone-survey.co.uk/services/damp-flat-roof-survey): A thermal check for trapped moisture beneath a flat roof membrane, aimed at landlords, managing agents and homeowners with an extension roof that never quite seems right. ## Key pages -

[Exeter, Devon](https://thermal-drone-survey.co.uk/areas/exeter): Thermal surveys across Exeter, where solid Georgian and Victorian walls in the old quarters and mass cavity-built estates on the outer ring lose heat in almost opposite ways. - [Topsham, Devon](https://thermal-drone-survey.co.uk/areas/topsham): Thermal surveys in Topsham, where listed merchant houses with no cavity to fill sit against an estuary that keeps every solid wall permanently a little damp. - [Exmouth, Devon](https://thermal-drone-survey.co.uk/areas/exmouth): Thermal surveys in Exmouth, where Regency and Victorian solid-wall villas share the town with seafront flat-roofed apartment blocks that lose heat in a completely different way. - [Budleigh Salterton, Devon](https://thermal-drone-survey.co.uk/areas/budleigh-salterton): Thermal surveys in Budleigh Salterton, where long-held Edwardian villas and a substantial stock of older bungalows have often gone decades without their insulation being checked. - [Sidmouth, Devon](https://thermal-drone-survey.co.uk/areas/sidmouth): Thermal surveys in Sidmouth, where an unusually complete Regency core with complex rendered roof geometries sits below later valley-side villas and post-war Sidford housing. - [Seaton, Devon](https://thermal-drone-survey.co.uk/areas/seaton): Thermal surveys in Seaton, where a large stock of shallow-pitched post-war bungalows sits behind Victorian seafront terraces, each losing heat through a different roof shape entirely. - [Axminster, Devon](https://thermal-drone-survey.co.uk/areas/axminster): Thermal surveys in Axminster, where a hilltop Georgian and Victorian centre sits fully exposed to wind from every direction, with former mill buildings and post-war estates around it. - [Honiton, Devon](https://thermal-drone-survey.co.uk/areas/honiton): Thermal surveys in Honiton, where a famously uniform Georgian high street sits in a valley prone to sitting fog, keeping roofs and walls damp through the winter months. - [Cullompton, Devon](https://thermal-drone-survey.co.uk/areas/cullompton): Thermal surveys in Cullompton, where cob and thatch survive in the old lanes behind a Georgian Fore Street, outnumbered by a large and continuing spread of modern estate housing. - [Tiverton, Devon](https://thermal-drone-survey.co.uk/areas/tiverton): Thermal surveys in Tiverton, where Victorian mill workers' terraces on steep streets sit below extensive post-war and large modern estates on the eastern edge of the town. - [Crediton, Devon](https://thermal-drone-survey.co.uk/areas/crediton): Thermal surveys in Crediton, where cob and thatch cottages in the lanes and barn conversions across the farmland edge carry some of the most varied insulation histories here. - [Okehampton, Devon](https://thermal-drone-survey.co.uk/areas/okehampton): Thermal surveys in Okehampton, where granite and slate Victorian terraces meet scattered moorland farms and longhouses on the wettest, windiest doorstep in this coverage area. - [Tavistock, Devon](https://thermal-drone-survey.co.uk/areas/tavistock): Thermal surveys in Tavistock, where a remarkable Victorian planned centre in solid Hurdwick stone sits in one of the wettest valleys in the network's coverage. - [Plymouth, Devon](https://thermal-drone-survey.co.uk/areas/plymouth): Thermal surveys in Plymouth, where a rebuilt post-war city of flat-roofed blocks sits beside Victorian terraces and modern waterfront apartments, three heat-loss pictures in one city. - [Saltash, Cornwall](https://thermal-drone-survey.co.uk/areas/saltash): Thermal surveys in Saltash, where old waterfront cottages on steep streets sit below Victorian villas and extensive post-war estates on gently exposed higher ground. - [Totnes, Devon](https://thermal-drone-survey.co.uk/areas/totnes): Thermal surveys in Totnes, where a dense medieval and Elizabethan core with slate-hung frontages sits above damp, tightly packed roofs with many hidden valleys and junctions. - [Newton Abbot, Devon](https://thermal-drone-survey.co.uk/areas/newton-abbot): Thermal surveys in Newton Abbot, where large numbers of Victorian railway-era terraces sit beside extensive post-war estates on the damp, low-lying floodplain of the Teign. - [Teignmouth, Devon](https://thermal-drone-survey.co.uk/areas/teignmouth): Thermal surveys in Teignmouth, where Georgian and Regency seafront terraces and converted flats face an unusual easterly exposure most South West detailing ignores. - [Dawlish, Devon](https://thermal-drone-survey.co.uk/areas/dawlish): Thermal surveys in Dawlish, where extensive post-war bungalow development on the cliff tops takes some of the most storm-exposed weather on the South Devon coast. - [Torquay, Devon](https://thermal-drone-survey.co.uk/areas/torquay): Thermal surveys in Torquay, where grand Italianate Victorian villas, converted flats and modern seafront apartments across seven hills carry three quite different heat-loss stories. - [Paignton, Devon](https://thermal-drone-survey.co.uk/areas/paignton): Thermal surveys in Paignton, where Edwardian and inter-war seaside terraces and semis, built in great number, form the largest single housing type on this site's coverage. - [Barnstaple, Devon](https://thermal-drone-survey.co.uk/areas/barnstaple): Thermal surveys in Barnstaple, where a Georgian and Victorian market centre sits on the tidal Taw, taking Atlantic weather with very little to break it before it arrives. - [Taunton, Somerset](https://thermal-drone-survey.co.uk/areas/taunton): Thermal surveys in Taunton, where a Georgian and Victorian county town centre is now surrounded on all four sides by very large post-war and continuing new-build estates. - [Wellington, Somerset](https://thermal-drone-survey.co.uk/areas/wellington): Thermal surveys in Wellington, where a Georgian and Victorian mill town with terraced mill workers' housing sits below an escarpment that accelerates wind over the town. - [Lyme Regis, Dorset](https://thermal-drone-survey.co.uk/areas/lyme-regis): Thermal surveys in Lyme Regis, where dense historic cottages on near-vertical streets sit on an actively unstable landslip coast that adds ground movement to the usual coastal exposure. ## What is on the record - CAA registered: Operator ID and Flyer ID held, plus the A2 Certificate of Competency. Every flight, including the early morning and after-dark ones this survey often needs, is planned to the rules that apply to the site. - Radiometric thermal camera: A DJI Mavic 2 Enterprise Advanced carrying a 640 by 512 radiometric sensor. Radiometric means every pixel is an actual temperature reading, not just a colour, which is what makes a genuine comparison across a roof or a wall possible. - 100 megapixel visual pass: A DJI Mavic 4 Pro with a Hasselblad camera flies alongside the thermal camera on every job, so a warm or cool patch on the thermal image can be matched back to the actual roof feature or wall detail underneath it. - Insured with Coverdrone: Full commercial cover for the operation. Certificates go to managing agents, landlords and insurers as a matter of course, without anyone having to chase for them. ## Contact - Phone: 07576 544932 - Email: info@exeterdronesurveys.co.uk - Enquiry form: https://thermal-drone-survey.co.uk/contact - Based in Exeter, covering Devon and the South West ## Optional - [Full text version](https://thermal-drone-survey.co.uk/llms-full.txt): every service, town and question on this site as markdown. - [Sitemap](https://thermal-drone-survey.co.uk/sitemap.xml) - [Privacy](https://thermal-drone-survey.co.uk/privacy) - [Terms](https://thermal-drone-survey.co.uk/terms)
