It starts with one resident noticing something feels cold.
They can't quite explain it. A wall that never quite warms up. A corner of the room that always feels damp.
They mention it to a neighbour. The neighbour checks theirs. Then tells the next door neighbour. Then the one across the street.
What started as one cold spot becomes a development-wide conversation. And then a development-wide problem. And then a bill for the house builder.
Cold spots at the eaves junction are one of the most common and most preventable issues in new build housing.
The eaves is where insulation often stops short.
A gap is left between the loft roll and the soffit below. Where warm indoor air meets a cold surface and condensation forms.
Left untreated, that condensation leads to damp. Damp leads to mould. And mould leads to the kind of resident complaints, legal exposure and remediation costs that can turn a profitable development into a very expensive lesson.
With Awaab's Law raising the accountability bar for damp and mould in residential properties, the stakes have never been higher. The homes being built today need to be right from day one... not remediated six months after the first resident moves in.
The ARC Eaves Insulator installs at first fix for around £300 per plot.
It keeps insulation continuous at the eaves junction, maintains the ventilation your roof needs and eliminates the cold spots that cause all of this in the first place.
