SURVEY 001 South Lanarkshire · est. 02 / 2008
Thermal imaging and air tightness testing for homes and commercial buildings across Scotland and the north of England — from an independent practice in Strathaven.
01 — Brief
A camera finds where heat leaves. A fan measures how much air goes with it. Neither one on its own tells you what to fix — which is why the two are booked together.
§ 01Thermography + blower door, one visit, one report.
The camera
Does not give you: a leak rate, or a certificate.
INSIDEwarm air, under pressure
OUTSIDEcold surface, lower pressure
The fan
Does not tell you which surface is cold, or where the heat goes next.
Together the image says where, the fan says how much. Air tightness testing
02 — Survey
Every job starts with a survey of the fabric — the walls, the roof, the junctions and the holes in them. These are the four services, and what each one is actually for.
§ 02Domestic and commercial · Scotland and the north of England.
| Service | What it finds | When you need it | Link |
|---|---|---|---|
| 01Thermal imaging | Temperature differences across the fabric: missing or wet insulation, thermal bridges, and the cold shape of an air path. | A cold room, a damp patch, a new-build handover — or before you buy. | |
| 02Air tightness testing | Air lost through leaks in the building fabric, measured at a controlled pressure difference. Level 1 and Level 2 tests. | Building compliance, a Passivhaus build, or a house that feels draughtier than it should. | |
| 03Heat loss surveys | Where the heat is leaving, room by room and junction by junction, read against the images rather than guessed at. | Before you specify insulation, glazing or a new heating system. | |
| 04Retrotec equipment | Sales and support for the full Retrotec blower-door range in the UK — 300 series through to 6000 series fans. | You run your own tests and need the fan, the gauge and someone who knows them. |
03 — Images
A thermal image is not a photograph of heat. It is a map of surface temperature, with the scale attached — and it means nothing without the daylight frame beside it.

04 — Air test
A blower door holds a set pressure difference across the whole building and measures the air needed to keep it there. That figure is the air permeability — and it is the one that goes on the certificate.
§ 04Level 1 & 2 · BS EN · Elmhurst scheme.
The full Retrotec range is used — from the small 300 series fans to the 6000 series — so the same team can test a single house, a school, a community centre, a retail unit or a large commercial warehouse. Passivhaus builds included.
“We have air tested thousands of buildings over the last 15 years.”

The team
Andrew McCulloch joined in 2018 and is a Level 2 Air Tightness Tester registered with the Elmhurst Airtightness Scheme. He runs heat loss surveys for homeowners, and much of his air testing and thermal imaging is on houses and community buildings along Scotland’s west coast islands.
