Attic Vac was engaged some 2+ years ago to provide following goods/services:
removal of old batts/vacuuming of roof cavity;
installation of new batts; and
installation of ventilation devices (whirlybirds/temperature activated fan).
Under company proprietor's (Barney's) supervision work was completed in a highly professional manner. Product quality is excellent. My home is now noticeably cooler in summer months. Transparent process; was progressively informed by Barney of work undertaken. Batts were positioned throughout roof area and particularly at its furthest reaches to maximise coverage (no short-changing/saving of material at customer expense).
Recently, some water stains appeared on ceiling of upstairs hallway. Called Barney, who visited immediately, identified problem (TV aerial badly installed) and promptly fixed it at no cost. Although problem was not caused by Barney's/Attic Vac's work/team, ownership was taken immediately and water leak fixed. That is what I call top quality after sales service.
Definitely value for money. Have no hesitation in engaging Attic Vac/Barney and his team again and recommending their services/products to anyone else. They will not be disappointed.

Approximate cost: $4,000
