Exposing Insulation – Do’s & Don’ts
Homeowner Guide
Published on the Aries Builders
Why Insulation Might Be Exposed During Repairs
During renovations, leak repairs, or flood reinstatement, it is normal and standard practice in New Zealand for plasterboard and insulation to be temporarily exposed.
This is required so builders can:
- dry out the framing
- complete repairs
- check for leaks
- carry out moisture testing
- identify any hidden problems
Short-term exposure of insulation will not normally cause issues as long as the area is dry and left undisturbed.
Some people may experience mild irritation or allergies if sensitive to dust or fibres, but this can be managed easily.
Do’s
1. Do understand that exposed insulation is normal during repairs
It is common, accepted, and safe for a short period during drying or renovation work.
2. Do keep the area isolated
We can place temporary plastic sheeting over openings if needed.
3. Do let framing dry completely
Sometimes walls must remain open for several days to allow moisture to evaporate.
4. Do be aware about any irritations or sensitivities
Some people are more sensitive to dust or insulation fibres. We can adjust the setup.
5. Do trust that insulation is left in place when safe
If insulation is dry, clean and intact, it stays — no need to disturb it.
Don’ts
1. Don’t worry if insulation is left visible for a short time
This is a normal part of the repair process and is safe.
2. Don’t close walls before timber is dry
Sealing moisture into a wall can cause mold later.
3. Don’t panic if mold is found
We follow a step-by-step procedure based on NZ guidelines.
If mold is discovered,
4. Don’t assume special equipment is always required
Negative-air extractors, HEPA vacuums, and dehumidifiers are only used when needed, not automatically.
