Indoor air quality (IAQ) is the air quality within and around buildings and structures. Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces, and computer modelling of air flow inside buildings.

Infrared cameras photograph heat rather than objects. The camera is a heat-sensor that registers different temperature levels and converts them into a film or video image. Most cameras use digital imaging, but some use chemical infrared film.

An infrared inspection can identify and document moisture intrusion, energy loss, and even unexpected hot spots.

In terms of energy loss, an IR camera can detect:

• heat loss and air infiltration in walls, ceilings, floors, windows and doors;

• damaged and/or malfunctioning radiant heating systems;

• air-conditioner compressor leaks;

• under-fastening and/or missing framing members, and other structural defects that can lead to energy loss; and

• broken seals in double-paned windows.

In terms of detecting moisture intrusion, an IR camera can locate:

• plumbing leaks;

• hidden roof leaks before they cause serious damage;

• missing, damaged and/or wet insulation; and

• water and moisture intrusion around penetrations and at the foundation and building envelope that could lead to structural damage and mold.

IR cameras are equally effective at locating hot spots in the home, including:

• circuit breakers in need of immediate replacement;

• overloaded and undersized circuits;

• overheated electrical equipment and components; and

• electrical faults before they cause a fire.

Additionally, based on the color gradients that thermal images provide, an inspector can locate:

• possible pest infestation, as revealed by energy loss through shelter tubes left by boring wood-destroying insects;

• the presence of intruders, such as rats, mice and other larger pests hiding within the structure and detected because of their heat signature that the IR camera captures; and

• dangerous flue leaks, which can lead to carbon monoxide poisoning of the home’s residents.

The purpose of an insurance inspection could be to:

1. Identify potential risks that could cause safety issues or losses, so that you can address them and avoid claims.

2. The home inspector may identify different areas where you would be eligible for discounts on your home insurance policy that you did not already have.

3. Making sure that the insured dwelling value is not too high or too low. This could save you money. Learn more about this in How to Negotiate a Change in Your Home insurance Value.

Investor inspections are stripped-down home inspections focusing only on major defects with the home, and an investor consultation is essentially an investor inspection with no written report.
