Community Housing Limited raised an issue of works with the contractor last week, giving seven days to provide a full report.

That report identified no specific items as causing the mould, but CHL will this month replace the roof and sarking, along with sending cameras into the pipes to look for leaks.

The contractor found the roof and sarking in the older property dated and in need of replacement.

They also reported the property was sealed well and had some insulation, and with the heat pump installed the property had the potential to sweat if not ventilated.

This was flagged as a potential contributor to the mould.

Issues with orientation of the house are still not being ruled out.

The contractor also gave some solutions they suggested would assist keeping the mould at bay including opening windows to ensure the property is appropriately ventilated.

Weather permitting, CHL expects the roof replacement and leak investigation to be completed within a month.

CHL state manager Melissa Palframan said Ms Byrne would not have to relocate during the works, and would not be disrupted by them.

Ms Byrne lives at the home with her three children, aged two, four and 13, all who suffer from asthma.

The young family spent nearly three months of winter without a working heat pump.

The home had also grown mould in most of the rooms, and on the children’s toys and clothes, despite Ms Byrne cleaning it daily.

A doctor’s certificate sighted by The Examiner also said exposure to the house could have contributed the children’s recurring chest infections

The certificate noted the children’s health improved when they were not staying in the home.

A maintenance request was first lodged with CHL in June, when the heat pump in their home began to blow cold air.

The issue was fixed during the initial call, but further issues arose within 24 hours when the unit again started again blowing cold air.

A second maintenance worker visited the property and diagnosed the issue as a faulty part, which was then ordered.

Ms Byrne was advised the part had been ordered and was supplied with a temporary electric heater.

This soon became too expensive to heat for the single mum.

A new, larger heat pump was installed last week.

Ms Byrne said she feels like she is fighting a losing battle keeping the property warm.
