What if nobody in Gisborne does this?
Then the honest answer is that it comes from out of the region, and the quote should say so with the travel in it. NovaPay asks locally first and widens rather than pretending the choice is bigger than it is.
Do rentals have to be insulated?
Yes. Ceiling and underfloor insulation has been compulsory in most New Zealand rentals for years, and the Healthy Homes standards set minimum levels along with heating, ventilation and moisture requirements.
Can I get help with the cost?
Possibly. Government-backed grants have covered a large share for owner-occupiers who meet the criteria, often linked to a Community Services Card or the area you live in. Ask installers, who deal with the schemes constantly.
Can old insulation just be topped up?
Sometimes, if it is dry, evenly laid and not degraded. Old or damp insulation is usually removed first, and that is a separate line in the quote worth seeing.
What is a ground moisture barrier?
A sheet laid over the soil under a suspended floor, stopping damp rising into the house. It is often the single most effective thing in an older New Zealand home and is required in rentals where there is enough clearance.
