Infrared thermal imaging to detect heat loss and hidden defects








Cold spots, draught paths and hidden moisture rarely announce themselves on a normal viewing. Our thermal imaging specialists carry out detailed infrared surveys across Fareham, from PO14 houses in Stubbington to PO16 flats near Trinity Street. We detect surface temperature changes to 0.1C accuracy, then turn those readings into plain-English findings that show where energy is being lost. The survey is non-invasive and non-destructive, so walls, floors and finishes stay intact while we map what the eye cannot see.
Fareham's housing mix gives thermal imaging real value. homedata.co.uk records show an overall average sold price of £350,303 over the last year, with detached homes at £504,001, semi-detached at £342,593, terraced homes at £285,741 and flats at £186,800. That spread points to very different building ages, construction types and retrofit histories across Marshall Crescent, Southampton Road and Longfield Avenue. A thermal survey helps separate a decent-looking finish from the insulation gaps, air leakage and cold bridging sitting behind it.

On a Fareham terrace, the first clue is often a colder band along a party wall or under a bedroom window. Our thermal imaging specialists spot heat loss through roofs, walls, floors and glazing, then look for cold bridging at junctions where insulation stops short. We also pick up missing or collapsed cavity wall insulation, air leakage around frames, hidden damp that cools a surface, underfloor heating faults and hot electrical connections that should not be running warm. The camera sees the pattern, and our surveyors explain why it matters.
Around Marshall Crescent in PO14 2FN, or in properties close to Trinity Street in PO16, the same camera can show different problems in the same weather. Newer plots may reveal unfinished seals around service penetrations, while older homes can show patchy loft insulation or a draughty loft hatch. Our external and internal scans are matched so the image is not read in isolation. That is how we separate a genuine defect from a harmless temperature pattern.

Fareham's market shows a wide spread between flats at £186,800 and detached homes at £504,001, and that spread usually mirrors different construction ages and upgrade histories. homedata.co.uk records show the overall average sold price at £350,303 over the last year, with 508 residential sales in the same period. In practice, that means our surveyors see everything from compact apartments near Trinity Street to larger homes around Stubbington and PO14 2FN. Each property type leaks heat in a different way, so a single inspection method is not enough.
Newer schemes do not remove the need for infrared work. Oakcroft Chase in Stubbington, PO14 2FN, currently has The Windermere plots from £350,000 to £370,000 on home.co.uk, while Southampton Road in Titchfield has 95 new affordable homes, split between 71 social rent and 24 shared ownership units. New homes should perform well on paper, yet small gaps around joists, sockets, vents and loft hatches can still waste heat. A thermal survey checks that the build quality matches the specification.
Planned growth at Newlands, south of Longfield Avenue, and Welborne Garden Village between Fareham and the South Downs will add more homes with modern insulation standards, but those standards only work if the details are right. Even in a new development, a missing seal at a window reveal can create a cold line that drags down comfort and energy efficiency. Older homes near PO16 or around Stubbington often tell the opposite story, where retrofit insulation has been added in stages and leaves gaps at junctions. We detect both patterns, then separate cosmetic finishes from the thermal performance beneath them.
Heat loss tends to follow the same routes across Fareham, whether the property sits near Southampton Road or on a smaller street off Trinity Street. In many homes, around 25% of heat escapes through the roof, 35% through the walls and 15% through the windows, so the biggest savings usually sit in the building fabric rather than the boiler cupboard. Our thermal images show where the envelope is failing, which gives you a clear order for loft top-ups, cavity fill checks, draught sealing and glazing improvements. The report turns a cold patch into a practical action list.
Energy upgrades make more sense when the defect is visible. A red line along a sill, a blue patch at a loft hatch or a cool band on an external corner points to exactly where money is being wasted, and that helps with EPC improvement planning. On homes close to Marshall Crescent, or in larger plots around Crofton View, we often find that a small repair can reduce heat loss more effectively than a cosmetic upgrade elsewhere. The value lies in prioritising the worst losses first, then checking the effect of each fix against the next thermal scan.

Send us the address in Fareham, whether that is PO14 2FN, PO16 or another local postcode. We arrange a slot that suits the property and the weather conditions.
Switch the heating on for at least 2 hours before we arrive. A strong indoor-outdoor temperature difference of 10C or more gives the clearest thermal contrast.
Our surveyors complete external and internal infrared scans, usually in 1-2 hours depending on size and layout. We check walls, roofs, floors, windows, doors and accessible services.
Each thermal image is reviewed, annotated and matched to the building layout. Reflections, recent sunshine and moisture patterns are considered before any finding is confirmed.
You get a written report with thermal images, clear explanations and practical recommendations. It shows which issues need quick action and which can wait.
A thermal image does not show colour for style, it shows temperature patterns. Blue usually means colder surfaces, while red, orange and white show warmer areas, and the colour spread across a wall in PO14 can be just as revealing as the image itself. In a terrace near Trinity Street, a bright strip above a window may point to air leakage, while a cold corner in a flat off Marshall Crescent can point to missing insulation or thermal bridging. We explain each image in the report so you can see the defect, not just the palette.
False readings need to be handled carefully. Sunlight on a south-facing wall, a reflective glass door, recent rain or a hot pipe behind a plasterboard finish can all distort the pattern, especially on elevations around Southampton Road or Longfield Avenue. That is why we compare internal and external scans and note the weather, the heating status and the room conditions at the time of the survey. A thermal survey only works properly when the image is read in context, not as a single snapshot.
Temperature differences also matter. If one part of a ceiling is only slightly cooler than the rest, it may point to a mild insulation gap rather than a major failure, while a sharp contrast often points to a more definite defect. In Fareham homes with loft access from the landing, or in flats around PO16 where service risers run through multiple levels, our annotations help separate a harmless pattern from a repairable issue. The report gives you a map, then adds the explanation that turns the map into action.
Homes in Fareham show different fault patterns depending on age and layout. At Oakcroft Chase in Stubbington, a neat finish can still hide air leakage at roof junctions, while plots near Crofton View may show colder edges where insulation has not been carried through fully. In Thackeray Lodge on Trinity Street, small losses around windows, balcony doors or service points can stand out clearly on an infrared scan. We also pick up cold spots around loft hatches and wall plates in older properties.
Newer schemes and retrofit stock each bring their own problems. The 95 homes on Southampton Road in Titchfield, the outline scheme at Newlands south of Longfield Avenue and the wider Welborne Garden Village programme all depend on details being finished properly, so thermal checks are useful even before a snag list has been closed. Older homes in PO16 often show poor loft insulation, missed cavity fill or draughts around doors, while flats can reveal hidden cold bridges at junctions. The same camera sees all of it, and the report explains which findings need an immediate fix.

It can detect heat loss through roofs, walls, floors, windows and doors, along with missing insulation, cold bridging, air leakage and moisture-related cooling. Our thermal imaging specialists also look for electrical hot spots and underfloor heating faults where those systems are accessible. In Fareham, that helps with everything from a PO14 terrace to a flat near Trinity Street.
Our thermal imaging surveys start from £300. The price reflects the property size, access and the level of detail needed, which can vary between a retirement flat on Trinity Street and a larger detached home near Crofton View. You get external and internal scans, image analysis and a written report with recommendations.
October to March gives the best results because the temperature difference between inside and outside is easier to maintain. We look for at least a 10C difference, and the heating should be on for at least 2 hours before the inspection. That contrast is useful in Fareham, especially on colder mornings around PO14 and PO16.
Most surveys take 1-2 hours, depending on the size and layout of the property. A compact flat in Fareham town will usually take less time than a larger home in Stubbington or a multi-storey property close to Longfield Avenue. After the inspection, our surveyors review the images and prepare the report.
Yes, it can identify the surface temperature patterns that often appear when moisture is present. Thermal imaging does not test moisture content directly, so we read the pattern alongside the property layout, weather and heating conditions. In older Fareham homes in PO16, damp at a wall plate or around window reveals often shows up as a cooler area.
The main preparation is to heat the property for at least 2 hours before the appointment and keep windows closed. Curtains may need to be opened in some rooms, and access to loft hatches, plant rooms or fuse boards is helpful if they are safe to reach. If you are in PO14 2FN, PO16 or another Fareham postcode, we will tell you what to leave clear before we arrive.
You receive an annotated report with thermal images and plain-English recommendations. The findings show which defects need quick action, which can be monitored and which may need follow-up with a builder or specialist. That makes it easier to plan repairs around the homes on Southampton Road, Longfield Avenue or anywhere else in Fareham.

Thermal imaging surveys in Fareham start from £300, and the final price depends on the property size, access and the level of reporting required. A flat on Trinity Street will usually sit at the lighter end of the scale, while a larger home in Stubbington or near Crofton View may need more time on site. The fee covers external and internal infrared scans, image review, annotation and a clear written report.
The on-site inspection usually takes 1-2 hours, then our surveyors review the thermal images and write up the findings. Reports are most accurate in October to March, when the indoor-outdoor temperature contrast is strongest and the heating has been running for at least 2 hours. That combination gives reliable images on homes in PO14, PO16 and the wider Fareham area, especially when the weather stays dry and the sun has not heated the walls.
For buyers and owners alike, the value comes from spotting problems before repairs get bigger. home.co.uk currently lists new homes at Oakcroft Chase in Stubbington, PO14 2FN, with The Windermere plots from £350,000 to £370,000, so it makes sense to check that the insulation and air-tightness match the spec on a fresh build. An infrared survey gives you a practical way to see where heat is escaping, then decide whether loft work, sealing or a follow-up repair is the right next step.
