Indoor air quality testing

Indoor air quality testing measures humidity, moisture and mould spores in your home. It means any work that follows is aimed at the real problem instead of a guess.

A common sign

“Someone in the house is always sneezing, and I don’t know why.”

Damp and mould you can’t see can affect the air you breathe. Testing shows what’s actually there before you spend money fixing it.

About indoor air quality testing

Know what’s in the air before you fix it.

An air quality specialist uses meters and samples to measure humidity, moisture in walls and floors, and mould spores in the air. The results show where the problems are and how serious they are.

You usually get a written report you can hand to whoever does the work. That helps make sure the fix matches the problem.

Worth knowing

Testing works best before any cleaning or treatment. Cleaning first can hide what the test needs to find.

Not sure where to start?

Stop guessing, start saving: find your home’s energy score.

Don’t waste money on upgrades you don’t need. A professional home energy assessment shows where your house loses heat and power, so your budget goes where it makes the biggest difference.

Heat recovery ventilation

Brings fresh air in without throwing the heat out with the stale air. What a tightly sealed house needs.

Sub floor ventilation

Fans and vents that dry out the space under the floor, which is where a musty smell upstairs usually starts.

Mould removal and treatment

Treating the growth and finding what is feeding it. Cleaning it off without fixing the moisture just delays it.

Ventilation You sealed the house. Now it's damp. Why a tighter house grows condensation and mould, what ventilation actually fixes it, and the order that avoids the problem in the first place.

Insulation Where the heat actually leaves your house Ceiling, walls, floor, windows and gaps, in the order they matter, and what each one is worth in a typical brick veneer home.

Start here The right order to upgrade your home Insulation before heat pump sizing, sealing before ventilation, and solar later than you would think. The dependencies nobody explains before you are quoted.
