Thermographic Survey in Shrewsbury

Shrewsbury's housing stock covers several building eras, and each one behaves differently under infrared. Homes built in the second half of the 20th century make up a large share of the town, with a median construction year of 1979, while 11.5% were built before the 1940s and another 4% by 1949. Properties from that older group often have solid walls, traditional roof spaces and patchy retrofit insulation, which means heat loss can concentrate at junctions, chimney breasts and timber lintels. Our thermal imaging specialists use those temperature patterns to separate normal behaviour from hidden defects.

Older homes around the medieval core and Shrewsbury Castle can be especially revealing under infrared, because timber framing and red sandstone hold and release heat differently from modern cavity wall construction. Over 660 listed buildings sit in the town centre, so many properties cannot be altered in the same way as standard brick homes on a newer estate. That makes a non-invasive survey useful before anyone starts insulation work, window replacement or damp repairs. The images show where to improve comfort without damaging original fabric.

Newer areas also benefit. Homes at Darwin's Edge near the A49 and Shrewsbury railway station, the planned Thrower Road scheme near Meole Brace, and Five Oaks in Bicton Heath already include features such as solar panels, electric vehicle charging points and heat recovery systems, yet installation gaps still happen. A thermal survey picks up missing seals, poorly insulated loft spaces and cold spots around new extensions or service penetrations. In practice, that means the report helps both older and newer properties cut wasted heat and reduce uneven room temperatures.

Thermal images use a colour scale, usually with cold areas shown in blue and warm areas moving through green, yellow, red and white. On a Shrewsbury property, a cold patch over a loft corner can point to missing insulation, while a streak of warmth beside a window may show a failed seal or draught path. The image itself is only the starting point. Our surveyors add labels and written notes so the report tells you what each colour change means.

Temperature difference matters. With a minimum 10C gap between inside and outside, heat loss appears clearly enough to identify the building element behind it, rather than just a random cool surface. We also watch for false readings caused by direct sunlight, reflective glass, wet surfaces and warm pipes close to a wall. That is why the report includes context, not just pictures.

Interpretation is where the value sits. A bright patch around an extractor fan may simply be normal appliance heat, but a repeating hot trail along a ceiling joist can show insulation voids or an overloaded electrical point. In older homes around the centre, timber, sandstone and later repairs can create mixed patterns that need a careful read. We explain each one in plain language, so you can see what needs repair now and what can wait.

Common findings in Shrewsbury include thin loft insulation in post-war houses, air leakage around timber windows in older terraces, and cold spots where later extensions meet the original house. Around Meole Brace and Bicton Heath, some homes built in the 1960s and 1970s show patchy retrofit insulation, especially after partial loft upgrades. In the town centre, timber-framed properties can show heat loss around junctions, chimneys and altered openings. Those defects are easy to miss without infrared imaging.

Frankwell has long been associated with flooding from the River Severn, and the Frankwell flood defences were completed in 2003. Surface water risk is a bigger issue across Shrewsbury than river and sea flooding, with 12.48% of properties at risk from surface water and 6.32% affected by rivers and sea flooding. Moisture ingress can leave thermal traces near skirtings, external walls and ground-floor junctions. A scan helps separate damp caused by leaks from cold surfaces or ventilation problems.

home.co.uk listings for Darwin's Edge near the A49 and Shrewsbury railway station show 2-bedroom semi-detached homes from £252,000, 3-bedroom semi-detached homes from £315,000 and 4-bedroom detached homes from £400,000 to £489,995. Five Oaks in SY3 5GD lists 2-bedroom semi-detached homes from £269,995, 3-bedroom homes from £359,995 and 4-bedroom detached homes from £424,995 to £529,995. Even newer homes with solar panels or heat recovery systems can hide installation gaps around roof windows and service penetrations. We check the whole envelope, not just the obvious defects.

Thermal imaging surveys in Shrewsbury start from £300, and the booking process is straightforward. Our thermal imaging specialists carry out external and internal scans, then annotate the results so each heat-loss pattern is tied to a room, wall or roof junction. The report usually follows soon after the visit, so you are not left guessing about the next step. For homeowners in Shrewsbury parish, that speed matters when a cold patch or damp mark needs a decision.

The best results come from a property that is already heated and ready for inspection. That means the heating on for at least 2 hours, the internal temperature stable, and a solid 10C difference between inside and outside. A survey in the middle of winter often gives the clearest picture, especially in homes around Frankwell, the town centre and older streets with mixed construction. If the conditions are too mild, the thermal pattern can blur and the report may need a second visit.

Cost aside, the useful part is the detail. You receive annotated images, plain-English explanations and practical recommendations that focus on insulation gaps, draught proofing, moisture ingress and possible electrical hotspots. For a house built in 1979, or a timber-framed property with later alterations, that can be the difference between a broad guess and a repair plan you can act on. A thermal scan does not replace every other survey, but it gives a sharp first look at how the building is actually performing.
