Thermal imaging surveys are revolutionising the way we detect hidden problems in homes — without lifting a single floorboard or drilling into a wall.

At Fitzgerald Surveying, we use advanced infrared technology to identify issues like heat loss, damp, missing insulation, and air leakage. Unlike traditional inspections, thermal imaging provides a non-invasive and accurate method to assess a building’s performance and spot faults before they escalate.

What Is Thermal Imaging?

Thermal imaging uses infrared cameras to detect and measure heat radiation emitted from surfaces within your home. These readings are converted into thermal images — allowing our surveyors to visualise temperature differences that indicate structural issues, insulation gaps, or hidden moisture.

It’s a highly effective way to assess the condition of walls, ceilings, floors, and roof spaces, especially when combined with expert analysis from qualified surveyors.

Why Is It Important?

Many common home issues, such as damp, poor insulation, and air leaks, don’t show visible symptoms until it’s too late. Thermal imaging allows us to:

Detect hidden defects early: Spot problems before they require major repairs.

Avoid invasive inspections: No need to damage walls or finishes to uncover issues.

Assess energy performance: Pinpoint where your home is losing heat and wasting energy.

Improve accuracy of surveys: Supports better decision-making with clearer evidence.

What Can Thermal Imaging Detect?

Here are some of the most useful insights gained from a thermal imaging survey:

Moisture & Damp: Cold areas in the imaging may indicate moisture ingress, leaks or rising damp — even when the surface appears dry.

Insulation Gaps: Easily spot missing, thin, or poorly installed insulation by identifying thermal bridges and temperature inconsistencies.

Heat Loss: Locate problem areas in walls, windows, and roofs where heat is escaping, helping reduce energy bills and increase comfort.

Air Leakage: Identify draughts or unintended airflow that reduce thermal efficiency and comfort in the home.
