Nick says other issues have included the wrong windows being installed twice, heat loss issues, and bare live wires hidden behind a wall.

The number of days that Cala said they would come to fix issues but then failed to turn up totals 45, he adds.

Cala say they have resolved the majority of items reported by Nick but have not been granted access to his home since January 2023 to allow the investigation of remaining items.

They say they offered to arrange for an independent surveyor to attend the home, which was agreed in April, but “the customer subsequently refused to commit to a date”.

After Nick arranged for professionals to inspect the property’s fireblocking (materials used to prevent fire spreading) he says they couldn’t guarantee that someone on the top floor would be able to get out of the house alive in a fire.

“The greatest thing to happen to me would be if this house went up in smoke,” Nick says.

“I wouldn’t have to deal with it… it’s just a nightmare.”

Cala Homes says there is no requirement to provide fireblocking around pipework with a diameter of fewer than 40mm in Scotland, that they never received a fire safety report from Nick and had not been granted access to assess the issue.

They add: “This home is across three storeys, it has a protected lobby (stairwell) with self-closing doors and door-seal brushes. These doors should not be fully airtight to allow ventilation and avoid a vacuum, which could stop a fire door from fully closing.

“This is in accordance with building regulations requirements and, along with fire alarms and smoke detectors, is part of the building control assessment carried out before a habitation certificate is issued.”

After receiving a thermal report from Nick that noted “fire doors and fire breaks require attention”, Cala says attempts were made to have them inspected despite them being compliant, but this “was not facilitated by the customer”, and no evidence was provided to support reports of air-flow issues.
