Thermographic Survey in Greenock

Greenock has a built fabric that ranges from 18th-century masonry to post-war blocks, so the thermal picture changes from street to street. The oldest surviving buildings on William Street date from 1752 and 1755, while the Historic Quarter includes the 1880s Municipal Buildings and other listed structures that were built long before cavity insulation became standard. Solid wall homes of that age lose heat steadily through the masonry, especially where internal insulation is absent, patchy or poorly joined around openings. A thermal survey shows where the wall is working against the room, rather than against the weather.

The post-war stock needs a different reading. Greenock built 32 multi-storey blocks between 1962 and 1975, and some were formed using system-building methods such as Camus, which means panel joints, roof edges and service runs can be weak points. Add in the Swedish Houses and BISF houses in Gibshill and South Maukinhill, and the local mix starts to look very technical very quickly. A camera scan can reveal cold joints, degraded seals, uninsulated voids and roof leaks that are hard to trace from inside a finished room.

Market data also tells its own story. homedata.co.uk records for Inverclyde show an average house price of £113,000 in March 2026, up 11.0% from March 2025, while semi-detached and terraced properties rose by 13.7% in the year to March 2026 and flats increased by 9.1%. That level of movement means buyers and owners have real money tied up in the fabric, whether the home sits in the West End Outstanding Conservation Area or in a newer scheme off Duncan Street. Greenock homes built after 1980 can still benefit too, because retrofitted insulation often fails at the edges, around windows or where later alterations cut through the original envelope.

Thermal images use a colour scale to make temperature differences easy to see. Cooler surfaces often appear blue or purple, while warmer areas drift towards red, orange or white, depending on the palette used on site. On a sandstone terrace in the West End or a tenement close to William Street, a cold stripe under a bay window can point to a draught route, missing insulation or a bridge where heat is moving out too quickly. The image shows the pattern, but the pattern only makes sense when it is tied back to the building details.

False readings can happen, so the scan is never read in isolation. Sunlight, reflected glare on glass, wet masonry after rain and warm surfaces that have been heated unevenly can all change how a wall looks on camera, especially near the Clyde waterfront or on south-facing elevations around Madeira Street. Our surveyors check the time of day, external conditions and the property layout before drawing a conclusion. That keeps the report grounded in building behaviour rather than a single coloured patch.

Each thermal frame is annotated so the homeowner can see what needs attention and why. A cool spot around a loft hatch in a Gibshill semi, a streak at a window reveal in Ardgowan Square or a damp edge on a flat roof in the Historic Quarter will be explained in plain language. Where the evidence points to a leak, we will say so. Where the image suggests a follow-up inspection is needed, that will be set out clearly too.

Our thermal imaging survey prices in Greenock start from £300. That includes external and internal infrared scanning, image analysis and an annotated report that explains what each thermal pattern means. We focus on heat loss, cold bridging, air leakage, hidden damp and any hotspot that needs a closer look, so the report is practical rather than generic. In a conservation flat near Ardgowan Square or a post-war house in Gibshill, the price also reflects the time needed to read the fabric properly.

For many buyers and owners, the cost is easier to judge against the numbers already in the market. homedata.co.uk records show Greenock's average price paid reached £143,000 on 9 April 2026, while Inverclyde sat at £113,000 in March 2026, up 11.0% year on year. If a thermal survey uncovers a failed loft layer, bad cavity fill or a leaking window detail, the fix can pay back through lower bills and better comfort. Best results come from October to March, with the heating on for at least 2 hours and a minimum 10C inside-outside difference before we scan.
