Home performance diagnostics | Coffs Harbour
A closer look at the place you call home.
I care about how your home is holding up, the environment inside it, and the people who live there.
Some conditions are easy to notice. Others take a closer look. I help you understand what's happening, what the findings mean, and what deserves attention.

The Home We Don’t See
The house, one room, the readings on a wall, then where each one is kept.
Demonstration property. Example values.
Why I look beneath the surface
Once I started measuring homes, I couldn't look at them the same way.
I began thinking about a family sitting down to dinner, and the conditions around them they couldn't see. About moisture in building materials, differences between rooms, and the air inside the places we spend our lives.
For me, understanding a home means looking at its condition and durability alongside the indoor environment, and caring about the health and wellbeing of the people living there.
Why the indoor environment matters
NSW Health notes that people with asthma, allergies or other breathing conditions may be more sensitive to mould.

Indoor pollutants can affect health at sufficient levels. The effects depend on the pollutant, exposure and individual sensitivity.

Joe Builds measures building and room conditions. Health questions belong with your GP.
Understanding more, together
I bring readings and observations together to look for patterns and explain what deserves a closer look.
That includes moisture, surface temperatures and indoor conditions, with dust and airborne particle screening where included in your assessment.
The range of testing keeps growing. Each assessment starts with your home, your questions, and an agreed scope.
I want to keep learning more about the places we call home, so we can take better care of them and the people we love.
