Infrared thermal imaging to detect heat loss and hidden defects








Our thermal imaging specialists carry out detailed infrared surveys across Solihull, from B91 2SW at Hampton Manor to B90 4JE in Monkspath. Infrared cameras detect surface temperature changes to 0.1C, so we can see where heat is escaping, where moisture is cooling a wall, and where insulation has failed behind finished surfaces. The survey is non-invasive and non-destructive, so we read the building without opening it up.
Homedata.co.uk records show Solihull's average house price at £410,000, with detached homes at £630,000 and flats at £210,000. Those values sit alongside 2,050 sales in the last 12 months, which means there is a lot of movement across the market and a lot of fabric that needs checking properly. From Knowle to Olton, a hidden draught or a missed insulation gap can keep running costs high and comfort low, especially in older brick-built homes and post-war estates.

Heat loss shows up first at weak points in the building envelope. We detect missing loft insulation, cold bridging at wall junctions, air leakage around windows and doors, and moisture that creates a colder patch on walls or ceilings. In a Solihull home near Solihull Town Centre, that can mean the difference between a room that feels even and a room that always needs the heating turned up.
Hidden defects do not stop at insulation. Our thermal imaging specialists also identify underfloor heating faults, overheating electrical components, and areas where rainwater has entered through a failed seal or cracked render. A bright hot spot near a consumer unit in B91 can point to an electrical issue, while a cool line at the base of a wall in Olton can point to damp or an air path that needs sealing.

Solihull has a housing mix that suits thermal imaging very well. Census data shows 39.1% semi-detached homes, 33.7% detached homes, 12.3% terraced homes and 14.6% flats, so we see everything from compact apartments to large family houses. The age profile matters too, because 13.9% of homes were built before 1919, 16.2% between 1919 and 1945, 44.2% between 1945 and 1980, and 25.7% after 1980. That means 74.3% of the stock was built before 1980, which is exactly the kind of housing where insulation gaps, worn seals and old alterations often hide in plain sight.
Age tells us a lot about construction. Pre-1919 homes in Solihull Town Centre or around the older streets in Knowle may have solid walls and little original insulation, while many 1945-1980 homes around B90 and B91 are more likely to have cavity walls, pitched roofs and a patchwork of later upgrades. Thermal imaging is useful here because it shows how those different materials behave on the same cold morning, and it helps us see where a retrofit has worked and where it has left a gap. The result is a clearer picture than a visual inspection can give.
New-build pockets still benefit from thermal checks because even modern homes can leak heat at junctions, loft hatches, window reveals and service penetrations. Hampton Manor in B91 2SW, The Green in Shirley at B90 4NE, and Monkspath in B90 4JE all sit inside a borough where Jaguar Land Rover, the NEC Group and Birmingham Airport help keep the local housing market active. Homes built or extended at different times often end up with mixed fabric, and that mixed fabric is where infrared imaging earns its keep.
Thermal imaging turns hidden heat loss into a visible pattern. As a rule of thumb, around 25% of heat can escape through the roof, 35% through walls and 15% through windows when insulation or airtightness is poor, so our survey helps you see which part of the building is doing the most damage. A clear thermal image of a ceiling in Shirley or a cold band around a bay window in Dorridge tells us where to focus first.
Those findings connect directly to energy efficiency. If the report shows heat leaking through a loft hatch, a cavity wall gap or a poorly sealed door set, the next step is usually straightforward repair rather than guesswork. In a house near Dog Kennel Lane, B90 4FJ, that might mean topping up loft insulation, improving seals, or checking that cavity fill has not slumped after installation. Each action reduces wasted heat and helps the property move towards a stronger EPC result.

The strongest thermal contrast usually comes between October and March. For a clear result in Solihull, we look for at least a 10C difference between the inside and outside temperature, and we ask for the heating to be on for at least 2 hours before we arrive. That lets us read the fabric properly, from Hampton-in-Arden to B90.
Choose Solihull and tell us about the property, from a flat in B90 4NE to a detached home in B91 2SW. We plan the survey for a period with strong thermal contrast, ideally October to March.
Keep the heating on for at least 2 hours before the survey. A 10C difference between inside and outside gives us the clearest reading across walls, roofs and window reveals.
Open loft hatches, clear access to radiators, consumer units and key wall areas, and let us know about recent repairs in places such as Knowle or Olton. Good access helps us scan the fabric without delay.
We carry out external and internal infrared scans, recording surface temperature variation to 0.1C. That lets us identify hidden insulation faults, cold bridging and moisture patterns without disturbing finishes.
Our surveyors compare each thermal image with the building layout and weather conditions. A dark blue patch near a ceiling in Monkspath means something different from a cool band at a window in Solihull Town Centre, so we read each frame carefully.
You get annotated images, plain-English notes and repair priorities. The report shows what needs attention first, which helps you plan improvements with less waste and fewer repeat visits.
Colour is the first clue. Blue and purple areas usually show cooler surfaces, while red, orange and white show warmer zones where heat is escaping or electrical load is higher. In a house near Hampton Manor, B91 2SW, a cold strip around a lintel can mean a thermal bridge, while a warmer patch near a ceiling line can point to missing loft insulation or a gap at the eaves. We read the pattern, not just the colour.
False readings need experience. A sunlit brick wall on a clear morning in Shirley can hold heat and look warmer than it should, while reflections from glass around The Green, B90 4NE can distort a frame if the angle is wrong. That is why our thermal imaging specialists plan the scan around weather, shading and recent heating use, then separate genuine defects from surface effects. The result is a report that explains why a spot looks the way it does.
Every finding gets annotated so you are not left staring at a colour map and guessing. We mark the cold zone, explain the likely cause and note the next action, whether that is loft insulation, sealant, ventilation improvement or a follow-up check by a building surveyor. For older stock near Solihull Town Centre or Dorridge, that interpretation is often the difference between a broad suspicion and a repair you can act on with confidence.
The 1945-1980 stock in Solihull, which makes up 44.2% of homes, often shows the same pattern of defects on infrared images. We regularly see loft insulation that has been moved aside, missing draught seals around replacement windows, cold spots at wall plates and heat loss at poorly insulated dormers in places like Monkspath and B90. Those issues are common in homes that have been updated in stages rather than renovated all at once.
Older homes in Solihull Town Centre, Knowle, Dorridge, Hampton-in-Arden and Olton can behave differently. Solid walls may show cooler patches after rain, pre-1919 brickwork can reveal moisture around window heads, and properties on Mercia Mudstone ground may show movement where shrink-swell behaviour has affected the fabric. We also watch for signs that point towards flood exposure from the River Blythe, the River Cole or surface water in more urbanised parts of the borough.

A thermal imaging survey can detect heat loss, missing insulation, cold bridging, air leakage and some moisture patterns. It can also highlight overheating electrical components and faults in underfloor heating circuits. In Solihull, that often matters in older homes around Solihull Town Centre and in post-war houses across B90 and B91 where retrofit work has been added over time.
Our thermal imaging surveys in Solihull start from £300. The exact fee depends on property size, access and whether the home is a flat in Shirley, a semi in Olton or a larger detached house in B91 2SW. You receive external and internal scans, image analysis and a written report with recommendations.
October to March gives the clearest results because the temperature difference between inside and outside is stronger. We aim for at least a 10C difference, and the heating should be on for at least 2 hours before the survey. That is especially helpful on modern homes in Monkspath and older brick homes near Knowle, where faint defects are easier to separate from the background.
Most surveys take 1-2 hours, depending on the size and layout of the property. A flat near The Green in Shirley may be quicker than a larger detached house around Hampton Manor or Dorridge. The report then follows after image review and annotation.
Yes, thermal imaging can show the temperature patterns that often accompany damp, such as a cool patch from moisture ingress or a damp chimney breast. It does not replace a full damp specialist report, but it is excellent for showing where the problem is strongest. In Solihull, we often use it to map suspected issues in older homes where rainwater, condensation or a failed seal could be involved.
A small amount of preparation helps a lot. Please keep the heating on for at least 2 hours, clear access to the loft hatch, and move items away from walls, radiators and consumer units where possible. If your home is in B90 4FJ or B91 2SW, we may also ask about recent works, because fresh decoration or new glazing can affect how the thermal images read.
Yes, and it can be very useful before any upgrade work is planned. Solihull has 20 Conservation Areas, including Solihull Town Centre, Knowle, Dorridge, Hampton-in-Arden and Olton, where older fabric can hide heat loss in difficult-to-access places. Thermal imaging helps us spot problem areas before repairs are discussed with a surveyor or contractor.

Thermal imaging surveys in Solihull start from £300, with the final price shaped by property size, access and the level of reporting needed. A compact flat in B90 4NE usually takes less time than a large detached home near Hampton Manor, so the fee can vary with layout and complexity. The value is in the output: clear infrared images, practical notes and a report that shows where heat is being wasted.
Turnaround is straightforward once the survey is complete. We inspect the property internally and externally, then analyse the images and annotate the findings so the report is easy to use, not just easy to read. For the best result, book between October and March, keep the heating on for at least 2 hours and aim for that 10C temperature difference, especially if the home is in an exposed spot near the M42, M6 or around Birmingham Airport.
