Thermal imaging survey for St Helens properties
Our Merseyside coverage takes in St Helens (WA10) and nearby Prescot, Huyton and Newton-le-Willows. It is about 11 miles east of Liverpool.
Where a St Helens wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. A survey in St Helens gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.
Exposure matters for every cavity wall. Merseyside has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
For regulations, if cavity wall insulation follows in St Helens, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

What thermal images can and cannot show
They show patterns, not proof. A cooler stripe inside might be missing fill, a cold bridge at a lintel or simply a radiator switched off. That is why we pair the images with borescope checks before recommending any work.
