Thermographic Survey in Reigate and Banstead

Reigate and Banstead's housing stock is split in a way that suits thermal analysis. Semi-detached homes make up 31% of households, detached homes 29%, flats 23%, and terraced homes 17%, while 34% of homes are 3-bedroom properties. Around 71% of homes are owner-occupied, 16% privately rented, and 11.5% socially rented, so we see everything from long-held family homes in RH2 to newer rental flats near Redhill. That spread matters because each construction type leaks heat in a different way.

Brickwork tells its own story here. Surrey houses were often built in English bond or Flemish bond, with blue burnt headers in some brickwork, and tile hanging is common over a brick or render ground floor. Cavity wall construction has been used since 1885, yet many Victorian and Edwardian homes around Reigate Priory, Reigate Castle Gateway, and Reigate Heath Baptist Church Windmill still have solid sections that bleed heat fast. In those properties, a thermal image often shows the roofline and wall junctions working harder than the rooms below.

Clay with flints over chalk, the Greensand Ridge, and the Low Weald give the borough a higher subsidence risk, around 1.6x the UK average, because shrink-swell behaviour affects foundations in dry spells. That matters in streets such as Shearwater Road and Gander Green Lane, where raised radon and older drainage can sit alongside draughts, cracked mortar, or poorly ventilated rooms. The borough had close to 60,000 households in 2021 and 63,231 dwellings in 2023, so small thermal defects add up across a large housing stock. Homes near the River Mole, Redhill Brook, Coles Meads, and South Merstham also need careful moisture checks because local flooding history can leave a thermal trace.

Colour matters on a thermal image. Cold areas often show as blue or purple, while warmer areas move through yellow, orange, red, and white, so a leaking loft hatch on Castle Drive or a cold corner at Roebuck Close is easy to pick out once the palette is read properly. The image does not show the fault itself, it shows the temperature pattern created by the fault. That distinction is why a trained surveyor matters.

Sunlight, reflective foil, wet render, and internal heating patterns can mislead the eye. A south-facing wall in Reigate town centre can look warm after a bright afternoon, so we choose conditions that cut solar gain and cross-check every patch with the building layout. Older homes near Reigate Priory may also show thermal drift around chimneys, while a new-build flat in The Vale can show reflections from glazing or metal fittings. Our analysis strips those false readings out before the report is issued.

Our reports annotate each finding with plain language and a fix priority, which helps owners in Banstead SM7 or RH2 decide whether the issue is a simple draught seal, a loft top-up, or a stronger sign of moisture ingress. We also explain where the camera sees surface change rather than the hidden fault itself, so the image is read in context, not in isolation. That approach works well in homes with awkward layouts, including listed buildings and later extensions around Reigate Castle Gateway. The result is a heat-loss map that a homeowner can act on straight away.

Thermographic surveys in Reigate and Banstead start from £300. That covers an infrared visit, internal and external scans, and a written report with annotated images, so you can see exactly where heat is leaving a property in RH2, SM7, or around Redhill. The report is designed to show where the heat loss is happening and which repair will tackle it first. It is a practical way to judge whether insulation, draught proofing, or a follow-up inspection will give the biggest improvement.

Larger detached homes in Courtlands Park, listed properties near Reigate Priory, or homes with awkward access can take longer and cost more. The survey usually takes 1-2 hours depending on size, and the best readings come from October to March with heating on for at least 2 hours and a minimum 10C temperature difference between inside and outside. A smaller flat at The Vale can be quicker, while a larger house in Banstead or a period property near Castle Drive needs a fuller sweep. That extra time helps the camera read the fabric properly.

Accurate images depend on weather and timing. Winter evenings and early mornings work best, while strong sun on a south-facing wall in Reigate town centre or around Castle Drive can blur the result. If a home has recently been re-roofed, insulated, or fitted with new windows, we still scan it, because hidden gaps around joists, vents, and service runs can stay invisible until a heat map exposes them. The end result is a report that links the image to a repair list, not just a set of colours on screen.
