Thermographic Survey in Newquay

Newquay has a mixed building stock, and that variety matters. Older Cornish cottages often use granite, slate, cob or rendered masonry, while modern homes in places such as Kerdhva Treweythek, Hedhas Dowr and Trevithick Manor Park are built with current insulation rules in mind. Those newer homes can still hide defects at rooflines, party walls or service penetrations, especially if a fitting was rushed or a seal has failed. Thermal imaging shows the temperature pattern across both old and new construction, which gives us a practical way to separate normal building behaviour from a defect.

Traditional materials in the town include golden sandy killas, grey slatey killas, granite, polychrome brick, painted render, hanging slate and tiles. That mix creates very different heat-loss signatures from one street to the next, especially around Mount Wise, Quintrell Road and the harbour and historic core. A thick stone wall can look cool for a reason, while a badly insulated modern extension can look the same because it is bleeding heat. Our surveyors read the fabric, not just the colour on screen, so the report is grounded in construction knowledge as well as the infrared image.

Coastal conditions add another layer. Newquay faces sea-level exposure, river-related flood risk near the Gannel and a Coastal Change Management Area, so damp and wind exposure need careful handling during any survey. That matters because moisture can mimic insulation loss if the image is not interpreted properly. We check the building type, the weather, and the surface response together before we write a recommendation. The result is a clearer plan for loft upgrades, window replacement or targeted maintenance.

Thermal images use colour to show temperature differences, not actual wall colours. Blue areas usually indicate cooler surfaces, while red, orange and white suggest warmer surfaces, and the contrast between them is what tells us where heat is moving. That means a cold patch near a window may point to air leakage, while a warmer streak on a roof slope may indicate insulation missing in a neat line. Our surveyors read those patterns alongside the property’s construction, because a granite wall in the harbour and historic core behaves differently from a modern stud wall near Trevemper Road.

False readings can happen, and that is where experience matters. Sunlight on a south-facing wall, reflection from glass, internal pipework or a recent burst of heat from a radiator can all distort a frame. We also check for weather effects, since a damp surface can appear colder than the dry area around it and may be linked to moisture rather than insulation failure. Every report is annotated so the cause is explained, the risk is set out, and the next step is clear.

The strongest reports are the ones that connect the image back to the building detail. A cold line at a ceiling edge might point to poor loft insulation, while a repeated pattern along one elevation can suggest a draught path around openings or a failed retrofit. In Newquay, that kind of interpretation is useful in homes that have been refurbished in stages, because upgrades rarely happen all at once. We show the image, note the temperature pattern, then explain what it means in practical terms.

Our surveyors often find heat loss around older roof spaces, particularly where loft insulation has been topped up unevenly or interrupted by storage boarding. In properties built from granite, render or local stone, the junction between wall and floor can be colder than expected, which is often a sign of thermal bridging rather than a failed wall. Near the harbour and historic core, older fabric can also hide draughts around original openings, especially where later repairs changed the way the building breathes. Those findings are common enough to warrant a careful read, not a quick guess.

Newer homes are not free from defects. At developments such as Kerdhva Treweythek, Trevithick Manor Park, Hedhas Dowr and Trevemper Road, we sometimes see heat loss at roof penetrations, around window installations or at junctions where different materials meet. A modern home can look efficient on paper and still leak heat through a poorly sealed detail. When that happens, the thermal image gives a simple visual cue that helps the owner push for a fix before the issue becomes baked into the monthly bill.

Coastal exposure changes the picture again. The River Gannel side of town and lower ground affected by moisture can show damp-related cooling, which needs interpretation alongside building materials and recent weather. Sandrock, the local cemented beach sand stone, is relatively weak and can behave differently from harder granite, so the same type of stain or cold patch is not always the same fault. That is why our surveyors describe the pattern, the likely cause and the confidence level in the report. It gives you something workable, not a vague warning.

Our thermal imaging surveys in Newquay start from £300, which keeps the service clear and easy to budget for. That price suits homeowners who want a focused infrared inspection rather than a full structural survey, and it is often the right starting point for checking heat loss before insulation work or a window upgrade. We include external and internal scanning where access allows, then turn the images into an annotated report. The value lies in the clarity of the findings, not just in the camera time.

Accuracy depends on conditions, so we always look for the right thermal contrast before the survey goes ahead. October to March is the best season, the heating should have been on for at least 2 hours, and we need at least a 10C difference between inside and outside for the cleanest results. Bright sunlight, strong reflections and recent temperature swings can all blur the picture, which is why timing matters so much in a coastal town like Newquay. When the conditions are right, the report gives a practical view of what needs attention first, from loft insulation to draught sealing and moisture checks.
